Poor quality products will burn well. Therefore, we recommend that you check the fire resistance of polystyrene foam. A reliable sip panel will take a very long time to ignite and will go out on its own after a few seconds.

In order for a Canadian house made of sip panels to please you with its durability and quality, we recommend working directly with manufacturers, and not with intermediaries, who often deliver defects. And also pay attention to the cost of products and terms of payment: it is better to pay the full amount or the balance after receiving the goods at the site.

If you are looking for an opportunity to build a warm home for little money, consider building a house from SIP panels. The cost of a two-story “box” of 10*10 meters without finishing is around 17-20 thousand dollars. In this case, there is no need for additional insulation; you can move into the house immediately after construction (if communications are connected) and you can immediately begin finishing.

What is a SIP panel

The construction of houses from SIP panels began in the second half of the last century in Canada. The technology is simple, the construction of a building requires very little time (from two to three weeks, depending on the complexity of the project), it can only be cheaper, and even then not in all regions.

Houses are built from thermal insulation panels, which themselves have sufficient strength. In English, these panels are called SIP, which is an abbreviation for the following name: StructuralInsulated Panel. This translates as “Structural Thermal Insulated Panel”. It turns out, in theory, in Russian, the name of this material should sound like KTP. In reality, normal transliteration is used (replacing English letters with Cyrillic alphabet). As a result, the name “SIP panels” is in use.

This material consists of two, between which a layer of expanded polystyrene (foam) is laid. The result is a kind of sandwich (a construction “multi-layer sandwich”). Hence another name - sandwich panels.

When building a house, there are two types of assembly:

In our country, the first option is most popular. The wooden frame gives the structure additional strength. The load-bearing capacity of sandwich panels without a frame is more than enough for the construction of one or two-story private houses. But knowing that the house is built on solid timber is reassuring. This technology has one more advantage - maintainability. If there are problems, you can remove the damaged panel and replace it with a new one, which is impossible with frameless technology.

Advantages and disadvantages

Like any new technology for our country, building a house from SIP panels has its adherents and opponents. Opponents have the most important argument - the unnaturalness of the materials and the possibility of releasing harmful substances. Indeed, these boards consist of foam and OSB. Polystyrene foam is a common material and is only dangerous when it burns. OSB has also been on the market for a long time; it is made from pressed large shavings and wood chips. Resins containing formaldehyde are added as a binder. It is this binder that raises the most questions: formaldehyde is a strong poison and its presence in the atmosphere in large quantities causes poisoning.

Formaldehyde emissions must be controlled by the SES (sanitary and epidemiological station), and only safe building materials must be put on sale. So if you are planning to build a house from SIP panels, carefully choose the manufacturer - the quality of the material depends on his integrity. Panels assembled using German OSB from Egger are recognized as the highest quality and safest. Their formaldehyde emissions are E1 (safe).

Excerpt from GOST R 56309-2014 (date of introduction 2015-07-01): “Depending on the content (emission) of formaldehyde, the boards are manufactured in emission classes E0.5, E1 and E2.”

At the same time, they easily tolerate high humidity, do not absorb water and are not deformed.

SIP panel Egger E1 2800x625x174 (Romania) is the best option for walls. Height - 2800 mm, thickness of polystyrene foam - 150 mm. If you prefer “standard” ceilings with a height of 2.5 meters, then you should purchase Egger E1 2500x1250x174

German Glunz Agepan panels are also good, but few people use them. If we talk about Russian manufacturers, then you should pay attention to the products of the Kalevala company. Only safe and high-quality materials are used in production:

1. OSB-3 Kalevala Russia emission class E1;
2. Glue – TOP-UR (Russia);
3. Expanded polystyrene – PSBS – 25C Knauf (Russia).

Speaking about the advantages of construction from SIP panels, it is necessary to pay attention to the fact that the technology has been thoroughly developed. Panels are produced for various elements of the house: external walls, partitions, interfloor ceilings, etc.

Why do people build houses from SIP panels? Because such a house has solid advantages:

• Light weight, which allows you to save on the foundation. Pile or construction is ideal for this type of building.
• Low heat loss, low heating costs. Expanded polystyrene is an excellent insulation material, and it is sandwiched on both sides with OSB sheets. This is what makes a sandwich panel house very warm.
• Low cost per square meter.
• Short construction time. The box of a two-story house can be assembled in a month.
• No shrinkage. There may be settlement at the foundation. The structure made from SIP panels has no settlement.
• Finishing work can begin immediately after the box is assembled.

In general, it is this set of properties that makes people choose a house made from SIP panels. They build both permanent residences and seasonal summer cottages. So, with a limited budget, building a house from SIP panels can be a very good solution.

How to build it yourself

There are two ways to build a house from SIP panels with your own hands:

• Buy a house kit for a specific project from a company that deals with this, and assemble it yourself. Not all companies agree to this, but many have a supervising installation service. This is when a company specialist supervises your installation.
• Buy slabs. Cut them to the required sizes, purchase timber, do it all yourself. In this case, all responsibility for the quality of construction will fall on you. If you have carpentry skills or have someone to help you with, you can choose this option.

Briefly about what a house kit is. This is a set of ready-made SIP panels, wooden beams of the required size and fasteners for the construction of a specific house. All components are cut at the factory and numbered. When assembling, you use the resulting blocks in a certain order. The process is reminiscent of building a house from a children's construction set, only you are assembling a real house.

Building a house from SIP panels when ordering a house kit is like playing construction kit

A house kit is good if everything is done accurately. This is not only about the quality of SIP panels (it must be checked separately), but also about the use dry wood (kiln drying), and about cutting accuracy. The edges of the panels must precisely “grab” the beam, the two panels must be joined with an expansion gap of about 3 mm - all this is achieved using precision equipment.

Reference. The expansion gap is the required distance that is left between building materials that are subject to expansion (dilatation). If a house is being built in a region with a humid climate (for example, the Leningrad region), then it is imperative to leave an expansion gap, otherwise the OSB will swell. In dry climates, there is no need for a gap between OSB.

Construction stages: photo report

Construction of a house from SIP panels, like any other, begins with the selection and construction of a foundation. A pile foundation is considered optimal for a lightweight house. This is exactly what is done in most cases when starting the construction of a house using SIP technology. Sometimes it is impossible to install a pile foundation:

• on hard soils that are too expensive to drill (rocks);
• on unstable soils with low bearing capacity (peat bogs);
• in the presence of cavities in the rock mass.

In these cases, they do or (more often USHP - an insulated Swedish stove). They are much more expensive, but more reliable.

Once the foundation has been selected and calculated, its construction can begin.

Making a pile foundation

Since foundations are most often made from screw piles, we will illustrate exactly how they are made. Piles are screwed into the ground manually (if the soil and strength allow) or using special equipment. The height of the heads is 80 cm above ground level, the distance between the piles is no more than 2.5 meters.

The heads are welded to the installed piles, and the strapping beam is attached to them (in this example, 200*200 mm).

Important! The joints of the timber must be located on the heads. When laying the strapping beams, do not forget to coat the locks with a protective compound (bitumen mastic) before joining.

There is no support under the joint - you can’t do that!

To protect against rotting and insects, the strapping beams are impregnated with a protective compound. Roofing material was laid in two layers under the timber (on the heads).

This stage takes from 3-4 days to a week. It depends on the complexity of the soil, whether you work with the equipment or turn it yourself. Now you can start laying the floor slabs, but before that you should familiarize yourself with the methods of connecting them.

How to connect SIP panels: basic principle

When connecting panels, a wooden dowel (beam) or a thermal key (a piece of SIP panel of smaller thickness) is inserted between them. As mentioned above, in our country the technology using a frame is more popular, i.e. Dry timber is used as a key. It is this option that we will focus on.

The beam is inserted into the groove and fixed using self-tapping screws and/or nails, which are twisted/hammered through the OSB into the body of the beam. If you have a nail gun, we initially recommend tackling the panels with “yellow” wood screws 40-50 mm long, and then punching through the joints rough nails 50-65 mm long in increments of 10-15 cm.

The following can be used to fasten SIP panels: “yellow” wood screws, galvanized screw nails, galvanized rough nails. Do not use “black” hardened screws - they break off and quickly corrode

There is always a risk that the connection will be leaky, and the entire construction technology of SIP panels is based on the thermos effect, that is, on maximum tightness. Therefore, before assembling this unit (and any other), foam is applied to the side surface of the panel. It fills all the cracks, providing the proper level of heat and moisture insulation.

Note! The picture above shows a dowel made from double timber. Often such recommendations are perceived incorrectly, and in order to save money, unplaned edged boards 50x150x6000 mm of natural humidity are purchased. Once the board dries, the joint is unlikely to remain sealed.

When making a composite wooden dowel 100*150, in our opinion, it is preferable to use three dry bars with a cross-section of 50*100 mm - in this case the connections overlap (see video below).

If we are talking about wall panels, then it makes sense to insert and secure the dowels in advance.

The foam was applied, the beam was inserted, and secured with self-tapping screws. Foam was applied to the side edge of the second slab, the groove was placed under the protruding part of the beam, an expansion gap of 3 mm was set, and secured with self-tapping screws. The foam that came out of the seams during the installation process is cut off after polymerization.

This technique, with minor modifications, is repeated in any connection of SIP panels. The diagram of this node is presented above.

After cutting the slabs, it becomes necessary to remove polystyrene foam to the required depth. For these purposes, an electric thermal knife (cutter) for foam plastic is used. They come in various designs, but the thermal knife must be equipped with a limiter. Only in this case will you be able to remove polystyrene foam exactly to the required depth. “Overdoing” can lead to the appearance of cold bridges at the junction of the panels.

You can make the cutter yourself, but at the same time Do not forget about safety precautions when working with electric current.

First overlap

The first floor is nothing more than a floor that does not require insulation. As melted, it is assembled from SIP panels with a thickness of 224 mm and a width of 625 mm. With such a width of the slabs, the wooden beams are spaced at intervals of about 60 cm, which is enough to withstand the load.

If you have slabs with a width of 1250 mm, then they need to be sawn lengthwise into two equal parts.

When installing the ceiling, the panels should be laid like bricks in masonry - with the seams mismatching (staggered). This is necessary to ensure that the seams do not warp when humidity increases.

These are the pieces that floor blocks should be cut into when using 1250 mm wide slabs

To protect the bottom OSB board from moisture, each of the boards is coated on one side with the same bitumen mastic. You can use other compositions with similar properties.

Assembly of SIP floor panels for the first floor

When connecting the slabs, a mounting beam is laid between them (diagram in the previous paragraph). The beam is attached at the edges to the frame (with long nails), and the edges of the slabs are attached to it using self-tapping screws.

We cover the side sections of the slabs (all floors) with an edged board of a suitable size. We apply foam to the side surface of the slab using a snake, then we place a board and fasten it through the OSB with self-tapping screws into the end of the board.

A starting (crown) board is laid on top of the sandwich along the perimeter, on which the SIP wall panels will rest. It is laid around the perimeter and in those places where partitions will be installed.

The crown boards are fastened with nails/screws, but to be sure, they were secured through and through with studs to the pile heads. Holes were drilled for the studs. A pin is driven into them and tightened with bolts.

Walling

We continue the construction of a house from SIP panels: we are installing the walls of the first floor. For this work, it is advisable to have two assistants, then the process will go faster and easier.

We place the first panel so that it “fits” onto the crown board

Wall installation begins from one of the corners. When installing, the panel is “slipped” onto the installed starting board with a recess at the bottom (first apply a layer of foam to the board or the end of the sandwich). The panel is placed, aligned vertically, attached to the starting board on both sides with self-tapping screws in increments of 10-15 cm.

Foam is applied to the side surface of the installed slab, and another slab is set at an angle of 90°. An embedded board (end block) is pre-attached to its side part, the thickness of which is equal to the depth of the groove. Like the first one, this panel is attached to the strapping starting board.

In addition, we fasten the corner using long self-tapping screws.

As a rule, self-tapping screws with a length of 220 to 280 mm are used

The length of the self-tapping screw must be such that it passes through the slab and the entire thickness of the embedded board. The installation step of this fastener is 40-50 cm.

In window and door openings, for more reliable fastening, you can install metal perforated reinforced corners. The element is optional, but adds rigidity and inspires confidence.

External walls and partitions are immediately erected

The installation of partitions from SIP panels follows the same principle: we attach a crown board and partition blocks to it. They can be the same thickness as for external walls, but thinner ones can be used. The decrease in sound insulation properties is compensated by the interior finishing.

To save money, partitions can be made using frame technology. Then initially only the frame can be installed, and its covering can be transferred to a later period. It is more convenient to do this when the roof is already installed.

In a house, frame partitions can be made from SIP panels

Interfloor ceiling

To install floor slabs in the grooves of wall panels, boards are installed on foam and self-tapping screws. They create a harness for installing the ceiling.

Next we lay the floor slabs. If the partitions are assembled from SIP panels, their load-bearing capacity is quite high and no additional reinforcement measures are required. If the partitions were assembled using frame technology, we make the upper beams reinforced: they are assembled from three boards glued together. For greater strength, the beams can also be fastened on both sides with self-tapping screws.

Floor slabs made of SIP panels are laid on the finished frame. They should be no more than 625 mm wide, they should be laid staggered (with the seams mismatched). Since the panels are narrow, there is a lot of wooden beams in the ceiling. Due to this, such a floor can withstand loads in places where there are no floor beams.

We fasten the laid slabs to the framing beam with self-tapping screws or nails. The edges of the OSB are at the top and bottom to each intermediate beam. After securing the installation of the ceiling, we close the open side sections along the perimeter of the building according to the same principle: foam + edged board. For greater rigidity, in those places where the floor beams pass, we fasten the floor panels with long self-tapping screws (220 mm) all the way through.

This stage after assembling the first floor does not seem difficult. Everything is the same, only the work is at height, tightening the sandwich panels takes longer and is more difficult than installing them.

Second floor walls

The second floor in this project is , so the wall panels are low. We also install partitions at the same time as the external walls. Before installing the roof, an embedded beam is installed in the upper open groove; roofing SIP panels will be attached to it.

Standard panels will have to be cut to fit the gables, since the shape is non-standard. The installation and connection of the wall panels themselves on the second floor is no different.

Roof made of SIP panels

Special sandwich panels are used for the roof. Under them, the ends of the slabs are cut at a certain angle, which is determined by the angle of inclination of the roof slope. Here, just as with flooring, you can get by with a minimum of beams, because each connection has its own beam. Therefore, the rafter system is not assembled.

For a roof made of SIP panels, beams need a minimum

Skate decoration

The roof of a small to medium sized house is made of SIP panels and usually has a central ridge beam. Here two planes of the roof converge. This node can be designed in two ways (in the pictures below). The first one is symmetrical. The sandwich panels are cut at an angle, and the top of the ridge beam is cut at the same angle. Two planes are fastened with long self-tapping screws through the panel to the beam on both sides. The fastener installation step is 30-40 cm.

In this method, there is no usual timber between the two slabs; they are connected only by foam. After the foam has polymerized, the excess is cut off, the seam is treated with a waterproof sealant, after which a protective strip - made of metal, plastic, etc. - is put on the ridge. - depends on the type of roofing chosen.

There is another way to join roofing SIP panels on the ridge. The second method does not require cutting the slabs at an angle, but one part of the panels must be longer (by the thickness of the roofing slab). The beam is still cut at an angle, the slabs are joined at right angles, and fastened through and through with long self-tapping screws to the beam.

This connection uses embedded end bars. They are installed as usual - using mounting foam and self-tapping screws. To block the access of moisture to the under-roof space, the junction of the two panels is also additionally coated with a waterproof sealant.

There is an option to install a roof from SIP panels without a central beam. There are roofing options with two load-bearing beams that are located off-center. These can be either specially laid floor beams, or partitions assembled from SIP panels or using frame technology. In the second case, it is better to strengthen the beams (make them prefabricated with glue and nails).

The most difficult thing in this unit is to cut the embedded beams at the right angle. This can be done on the ground, which greatly simplifies the task. The panels are fastened through the slab with long self-tapping screws to the floor beams or mortgages in the partitions. Also, two planes are fastened together at the junction point - on opposite sides with long self-tapping screws.

Roof and wall panel connections

For laying SIP roofing slabs, wall slabs are cut at the required angle. The inner part of the OSB is higher than the outer part. The foam plastic is “cut” at the same angle, and the edges of the embedded beam are trimmed. It is this part that is the most difficult if you did not buy a house kit, but are building a house from SIP panels using standard panels, cutting them to the required dimensions with your own hands.

How to connect wall and roof SIP panels

If you have the appropriate equipment, cutting them at an angle is not a problem. The problem is cutting the foam between the OSB boards to the required depth. You can select the core using a thermal knife, and then remove the remains purely mechanically. Most likely, the cut will still not be smooth, so you will have to add more foam to fill the unevenness.

In the pictures, the roof overhang is also made of slabs with insulation. This is easier to implement, but it is an unreasonable expense. To save money, the length of the SIP panel is taken up to the intersection with the walls, and then only the timber goes (as in the photo). In this case, the beam is made composite: one part is longer by the amount of the overhang, the second is shorter and ends where the wall ends.

Features of joining roofing slabs

The connection of two roofing slabs occurs in the same way as others: timber, foam, self-tapping screws. But since precipitation is possible here, it is advisable to seal all seams.

To improve the tightness, all seams on the roof are additionally coated with waterproof sealant. First, the hardened foam is cut into a plane with the roof, then a sealant is applied. After filing the overhangs, we can consider that the construction of a house made of SIP panels is completed. Install windows/doors, connect communications and the home is already suitable for habitation. Finishing can be done immediately after installing the box.

Mice and other troubles

To save our readers from unnecessary headaches, we decided to talk about the mistakes made during the construction of one residential building. First of all, the material is intended for those who hire contractors for construction. However, it will also be useful for those who build a house on their own.

The facility was built under the “Rural House” program, and local would-be builders acted as the contractor. Unfortunately, the future residents did not pay due attention to the quality of the work. The result is natural - a large number of significant “jambs”.

Brief information about the house:

• Commissioning date: 2008
• Number of floors: 2
• Foundation type: strip
• Technology: frameless
• Panel sizes: 2740x1220x224 (floors), 2740x1220x174 (walls), 2740x1220x145 (dowel for connecting wall panels)

Problems appeared quite quickly and were associated with the most important part of any structure - the foundation. The strip foundation was filled with low-quality concrete, which led to the fact that when moisture entered, it began to crumble.

In extreme cold (below -30°C), another “jamb” was discovered - part of the plastic floor plinth in the kitchen froze.

It was decided to remove the bottom panels of the vinyl siding, remove the cold bridges where the wall slabs adjoin the first floor ceiling, and sheathe the foundation with corrugated sheets to look like stone.

After dismantling the lower siding panels, signs of field mice appeared.

During construction, the ends of the floor were not covered with boards. Pieces of plywood are installed, with large distances between them. Also note that the roofing felt does not start from the timber, but from the floor level

A brief explanation of roofing felt. At the time the house was built, vapor-permeable membranes had not been heard of in a particular locality. The contractor was going to lay plastic sheeting on the walls. The customer opposed this, and as a result, roofing felt was used.

It is clearly visible that the mice did not waste any time...

As a result, the owner of the house had to mitigate the consequences using his modest construction experience.

Related errors:

• The lower part of the first floor ceiling has not been treated with bitumen mastic.
• SIP panels with a width of 1220 mm were laid on the floors of the first and second floors (they had to be cut in half lengthwise).
• Raw wood was used.
• The panel for making thermal keys is thinner than the polystyrene foam layer.
• The corners of the house are not tightened with long screws.
• Self-tapping screws are exclusively black.

There were other mistakes, but we do not talk about them, as they do not directly relate to the technology of constructing SIP houses.

Alas, the case discussed above is not the most severe - the fatal option is discussed in the video below.

The conclusion is very simple: you should not blindly trust the customer. All stages of construction must be supervised personally, or seek the help of a knowledgeable person from the outside.

If the construction is carried out by contractors, then the quality of their work can be assessed already at the stage of acceptance of the first floor slab.

Installation of SIP panels. Instructions

An example of installation of SIP panel units is given for the use of panels with a polystyrene foam insulation thickness of 150 mm and OSB walls of 12 mm.

Depending on climatic conditions and customer objectives, it may be advisable to use thicker panels with 200 mm insulation

Node No. 1. Foundation-Floor-Wall

Let us remind you that when building a house on a monolithic slab, there is no need to use strapping beams and SIP panels as the floor. Therefore, we will dwell in more detail on the features of installation on strip and pile foundations.

As for the slab, it is more cost-effective to use other methods of insulating the subfloor, for example, high-density extruded polystyrene foam.

Placed on the foundation 2 or more layers of waterproofing to prevent wood saturation with moisture. This condition applies to all types of foundations.

The waterproofing must be strong enough so that the weight of the entire house does not compromise the properties of reliable insulation from moisture for decades.

A strapping beam is laid on the waterproofing and is securely attached to the tape in increments of 400 mm or to the pile heads. The strapping beam should be at least 45x145 mm in size, but it is better to use a larger size, for example, 90x145 mm or 145x145 mm.

Read more about the features of its installation in the description of foundation arrangement.

Secure the strapping beam into the tape using anchor bolts with a diameter of 12-14 mm. The bolt nut should be recessed into the beam and not stick out. To do this, you should pre-drill a small hole in it with a larger diameter than the nut. The anchor must extend at least 100 mm into the foundation.

Secure the strapping beam to the pile using a 12-16 mm stud with 2 nuts. The ideal option is to weld a pin into the center of the pile head, extending 100-200 mm inside the pile, followed by concreting the pile and welding the head to it. 2 or more layers of waterproofing are also laid on the pile, and the pin passes right through the strapping beam. It is cut to the level of the timber and fixed with a nut with a pre-prepared hole so that the nut was recessed into the timber.

The installation of SIP panels begins on the strapping beam in accordance with the installation plan. For the floor, it makes sense to use 625 mm wide panels to increase the number of joists. The foundation design must take into account the presence of support points and tie beams under all internal walls.

In quality construction they try to reduce the number of cold bridges and, accordingly, thermal seams. Therefore, it is advisable to mount the external wall of the SIP panel before attaching the strapping beam, and start the floor panel behind this external wall (see Unit 1.1). This solution will require the use of a taller SIP wall panel.

Economical option provides for the installation of SIP wall panels directly on the floor panels. In this case, there will be 3 thermal seams instead of 1 (see Unit 1.2), but panels can be used of a smaller height. For builders, this solution is faster and simpler, since there is no need to cut each wall panel. But it’s up to you to live in the house!

By choosing one of these options, you can begin installing floor SIP panels. They will either be shifted to the center of the house by 12 mm (the wall thickness of the OSB wall panel) in the first option, or they will go flush with the strapping beam - according to option 2.

Floor panels are installed according to the layout plan using information on the installation of Unit No. 2 Panel-Panel.

An important nuance - the lower part of the floor SIP panels is covered with mastic, to protect them from moisture in the ground. If possible the lower thermal gap of the floor panels is also sealed. If it is impossible to gain access to it after installing the panel, it is necessary to apply sealant in advance

onto an already installed panel.

There is also an alternative opinion that mastic cannot be used on the lower part of the first floor floors. If moisture penetrates into the floors from inside the house, there will be nowhere for it to escape. This may occur due to poor-quality sealing of the seams (for example, they simply foamed it instead of using thermal seam technology).

The floor panels are fastened to the strapping beam first with a 4x60 mm self-tapping screw diagonally from the ends. This is necessary to prevent the panels from moving in the plane of the foundation. After the installation of all floor panels is completed, their ends are covered with an antiseptic dry planed board 45x145 mm (end board in the diagram).

Everything by technology the inserts of the beams into the panel must be pre-foamed with high-quality mounting foam-glue. In order for the foam to work as efficiently as possible, Before applying foam, surfaces should be sprayed with water from a spray bottle.. Polymerization of the foam occurs under the influence of moisture, and this simple action will achieve better quality of foam curing.

When the floor is completely ready, it begins installation of connecting beams for fastening SIP wall panels. You can use 45x145 mm (in the diagram) or 90x145 mm - depending on the design of the house and the required balance of strength and thermal characteristics. The wall fastening beam is foamed from below and placed on the floor SIP panel.

There is a modification of the technology when a roll of foam polyethylene insulation the width of a beam and a thickness of 2-3 mm is laid between this board and the floor SIP panel, or 2 grooves of 3-4 mm are made in the board and a cord of foamed polyethylene 6-8 mm is laid (in the diagram these insulation options are not presented).

The connecting beam of the wall is secured with a high-strength structural screw TORX M8x280 mm (purple in the diagram). The length of the self-tapping screw is chosen such that it passes through the floor panel to the middle of the strapping beam). Fastening pitch - 400 mm. This is a very important component for attaching the wall to the foundation; we do not recommend saving on it!

Do not forget about the correct location of the fastening board on the floor SIP panel. When working according to Option No. 1, the board is flush with the panel. When working according to economical Option No. 2, the board is shifted inside the house by 12 mm (the thickness of the OSB wall panel). Before installing the wall panel, the board fastening to the floor is sprayed with water and foamed on all sides (green seam in the diagram).

The wall panel is fastened to the fastening board from 2 sides (outside and inside the house) using TORX 4x60 mm structural screws with a pitch of 150 mm.

Node No. 2. Panel-Panel

SIP panels are connected to each other using connecting beam.

Its dimensions can be different: for panels with insulation thickness 150 mm, dry planed antiseptic timber with a width of 145 mm and a thickness of 90 mm is used (see diagram Option No. 1). The sampling grooves in the insulation are made 40-45 mm deep.

Lightly loaded structures can be connected by timber/board 145x45 mm (see diagram Option No. 2).

The same lightweight version is sometimes used for roof panels. The depth of the groove in this case is 20-25 mm.

Dry planed is also used board 145x25 mm for insertion into the grooves at the ends of SIP panels. For example, in the lower and upper parts of the wall, along the perimeter of the floor panels, these are the ends of the roof overhangs.

Before inserting the timber into the groove of the panel, it is necessary to moisten the surfaces with water using a sprayer, then apply mounting foam into the groove of the SIP panel.

If the size of the beam and the depth of insulation in the SIP panel are chosen correctly, then the thermal seam between the walls of the panels will be 3-5 mm.

For high-quality sealing of the seam it is necessary to use Izolon cord and sealant(see above). In this case, the thermal gap is called thermal seam - it will be elastic, air- and moisture-proof and will ensure a long service life of the SIP at home.

In cheap SIP construction, thermal seam technology is not used. All thermal gaps are foamed with mounting foam, which is cut off after drying.

The obvious disadvantage of this solution is that the foam gradually breaks down and crumbles under the influence of oxygen. Moisture will get into the seam, and this will not only bridge of cold, but also the likelihood of damage to the timber and the end of the panel fungi.

Cut ends of OSB boards SIP panels are most susceptible to fungal damage, so they must be treated with an antiseptic. Ideally, buy SIP panels immediately with processed ends + process the ends yourself when cutting a solid panel.

If a SIP panel is used 200 mm thick, For a more durable option, a connecting beam is suitable 195x90 mm, and for lightweight - 195x45 mm.

A durable option is used if the house is being built in volume or on several floors. A 195x25 mm board is also used to seal the ends of the panels.

In cheap SIP construction, builders can save money by using high-quality timber of the required thickness. There are 2 options for replacing timber with smaller boards.

Option No. 3

Instead of 90x145 mm timber, 2 dry planed boards 45x145 mm are used, fastened with self-tapping screws and foam. Obviously, this connection will provide a significant cold bridge over time.

Option No. 4

3 boards are used to recreate the size of the timber 90x145 mm. This option is more difficult to manufacture, but the cold bridge will be smaller than in option No. 3.

Node No. 3. Panel angle 90,45,135o

There are several options for assembly installation schemes. We will not present “Economy” options with boards sticking out and 3 thermal seams, as they are not recommended. Moreover, they do not save anything except 20 minutes of construction time.

The correct corner contains 1 thermal seam. In one of the panels it is necessary to make a cutout of the insulation and the inner part of the OSB to match the size of the second panel. After this, an additional sample of insulation is made using a thermal knife under a 45x145 mm beam and the inner beam is installed.

In the second panel, a sample of insulation is made for a 45x145 mm beam (indicated in the diagram) or (if it is necessary to structurally strengthen this corner), a sample and a 90x145 mm beam are used.

This corner beam is first fixed to the first panel with TORX 4x60 screws. It must be secured in such a way that there is room for the OSB walls of the second panel. If we are mounting a corner of the wall, then do not forget about the need for a fastening beam on the floor.

The second panel with the finished groove is inserted last. After leveling in all planes, the panels are secured to the fastening beams along the perimeter.

Using only 4x60 mm self-tapping screws is not enough to securely fasten the corner. The main fastening element in this assembly is a TORX 8x200 structural screw, which is fastened through the second panel into the fastening beam of the first panel with a pitch of 400 mm.

Sharp corners are installed using the same principle in SIP construction.

It is important to cut the fastening beam at the desired angle and take into account that if the beam is placed at an angle in a panel with 150 mm of insulation, the width of the beam must be more than 150 mm.

You may need dry planed timber measuring 45x195 mm or larger.

Also, the thickness of the timber used can be increased when it is necessary to strengthen a structural element.

Connecting SIP panels at an obtuse angle, for example, 135 degrees, can be done by analogy with the SIP panel - SIP panel unit (see above), but the connecting beam must be used longer, since it is also at an angle in the panel.

To simplify the installation of self-tapping screws at an angle, it may make sense to drill a 2.5-3 mm hole with a drill.

It is also possible to use thicker timber in installation - if necessary, strengthen the structure.

Node No. 4. Window and door assembly

The installation of window and door openings is shown in the diagrams in the section of the wall plane.

SIP panels are mounted in such a way as to create a window opening of the required size.

timber 45x145 mm is laid.

The timber is secured with self-tapping screws, and all seams are foamed, and the outside, after the foam has dried, is covered with sealant.

The beam is recessed flush into the panel. It is important to ensure that the timber is level. This will greatly facilitate the subsequent installation of windows.

The doorway is mounted in much the same way as a window. When installing walls the lower fastening beam remains on the floor until the installation of all sections of the wall is completed. This is necessary to ensure that the wall is level.

Upon completion of the construction of the door opening, the fastening beam in it is cut out and removed.

A small SIP panel insert above the door can be mounted and inserted separately. It is very important to ensure a uniform plane of panels to the left and right of the door.

As an option, you can pre-fix the connecting beam along the top of the panels, this will simplify the leveling of the plane.

There is an installation option with recesses in niches (windows, doors) of only 25 mm and the use of timber, respectively, measuring 145x25 mm.

The illustration shows an example of inserting a connecting beam into an opening before the stage of securing it with self-tapping screws.

Node No. 5. Interfloor ceiling

The installation of interfloor slabs in a SIP house can also be performed in several ways.

In our options The floor panels of the 2nd floor rest on the walls of the 1st floor and are fastened through and through to the fastening beam of the 2nd floor.(structural self-tapping screw 280 mm with a pitch of 400 mm in the diagram).

There is an opinion that it is cheaper to make a floor using standard frame technology - wooden logs and wool. But, if you take into account all the subtleties of the correct installation of frame floors and moisture/vapor barrier wool, then the option with SIP panels will not be much more expensive.

Most often used for floors SIP panels 625 mm wide, which allows you to increase the number of lags and the strength of the structure. In this case, the lags are the fastening beams in SIP panels.

The fastening beam of the 1st floor ceiling, 2nd floor floor and floor joists can be either 45x145 mm or 90x145 mm, depending on the required structural strength of the building.

Option #1

The installation of the first floor wall ends with a 45x145 mm beam in the groove of the wall panel. The interfloor SIP panel rests on it. It makes sense to immediately assemble a whole row of panels and secure the floors in rows according to the designed panel layout plan.

In Option No. 1, the floor panel is shifted by 12 mm into the house so that the OSB wall panel of the 2nd floor covers the floor. This allows you to make 1 thermal seam instead of 4. But in this case it is necessary to use higher SIP wall panels.

The logs themselves are not shown in the diagram, only the joint with the wall of the 1st and 2nd floors.

During the installation process, the floor panel must be fixed with temporary fasteners to the fastening beam of the wall of the 1st floor. After laying out a row along the wall, you should mount the fastening timber of the 2nd floor walls on the panels and tighten the structure with a long TORX 8x400 mm structural screw with a pitch of 400 mm.

SIP panels of the walls of the 2nd floor are cut from the inside to the thickness of the ceiling + insulation is removed from them using a thermal knife under the fastening beam of the floor of the 2nd floor.

Node No. 6. Mauerlat. Wall-Roof

The connection unit for a wall made of SIP panels is presented in the variant with ceiling covering of the 2nd floor also made of SIP panels.

Just as in interfloor slabs (see above), this slab can be made using different technologies, including those presented in the diagram.

The outer OSB wall goes all the way to the end of the wall. A cutout is made inside for installing the ceiling and a hole for the connecting beam. Installation begins with the installation of this connecting beam and bringing all the beams of this wall to the same plane using a laser level.

SIP panels we install the ceilings with the end board already fixed in them. Installation of panels should be carried out in rows, securing the panels to temporary fasteners so that they do not move along the installation plane.

We use the designed panel layout plan. For floors, SIP panels with a width of 625 mm are most often used.

The wall assembly ends with the installation of a beam called " Mauerlat". This is a thick beam beveled at the angle of the wall, for example, 150x150 mm. The Mauerlat is fixed through the floor panel to the connecting beam of the 2nd floor wall using TORX 8x280 mm structural screws with a pitch of 400 mm.

On the roof panel, which is also most often 625 mm wide, it is mounted locking block 50x50 mm - to rest on the Mauerlat and prevent the panel from sliding off the roof during installation. This block is necessary only for the convenience of starting the installation of the panel and will not bear the main structural load.

The main fasteners for the SIP roof panels are TORX 8x240 mm structural screws, also with a pitch of 400 mm.

Upon completion of the roof installation, the end parts of the roof panels are covered with boards 45x145 mm or 25x145 mm.

There is an option to install a roof with a SIP panel only up to the beginning of the wall. Then the roof is removed using the connecting beams of the panels (rafters), but without insulation inside. This solution saves on the required panel area, but ultimately depends on the span length and the need to cut panels or use whole ones.

Node No. 7. Run. Roof panels

The purlin is a thick beam, beveled at the angle of the roof, which transfers the load to the walls from the middle part of the roof (between the Mauerlat and the ridge). Purlin is required when the roof span is more than 4 meters long.

The purlin beam is mounted in the walls in a niche prepared for it. You need to select the insulation from the niche using a thermal knife and install the connecting beam according to the diagram.

The purlin cannot be installed in an unprepared opening, resting only on the edge of the OSB boards!

The connection of the roof panels is carried out at the installation site of the purlin beam. 45x145 mm or 90x145 mm is used as a connecting one (according to the design and calculations).

The connecting bars perpendicular to the mauerlat, purlin and ridge will serve as roof rafters.

SIP roofs do not require a separate rafter system underneath.

The main fastener of the unit is a structural self-tapping screw TORX 8x360 mm and 8x280 mm. The long self-tapping screw must also pass through the connecting beam under the purlin. Self-tapping screws 280 mm go in the span areas, between the walls.

It is possible to strengthen the structure with the help of galvanized mounting angles, which additionally secure the rafters to the purlin. When using them, you will need to make a small cutout in the next SIP panel at the corner.

The most popular solution is to use SIP panels with an insulation thickness of 200 mm in roof panels. In this case, a wider beam 45x195 mm or 90x195 mm is used.

There are solutions that involve the use of a standard rafter system UNDER a SIP roof. This makes it possible to increase the strength of the structure, but also increases installation time.

Node No. 8. Roof ridge

A ridge or ridge beam is the main load-bearing element of the roof, located at the very top of the frame. Usually this is a beam 150x150 mm or larger. For long, thick beams, it makes sense to use quality laminated timber solutions. They give minimal deformation and sagging.

The connecting bars of SIP roof panels are also a rafter system; they are tied together using a 45x145 mm board with TORX 4x95 screws. In this case, the strapping board runs along the outer layer of the SIP panel.

The main load-bearing fastener of the unit is a TORX structural screw 8x240 mm. In the case of fastening through the cross section of rafters with a thickness of 45 mm, it makes sense to drill a 5-6 mm hole for a self-tapping screw in the rafters to prevent them from cracking during installation.

It also makes sense to fix the rafters with mounting angles to the ridge beam, and also to connect the rafters of different roof slopes with a galvanized plate.

SIP panels: material characteristics, advantages and disadvantages, reviews from residents

SIP panels, which are used for the construction of non-residential buildings and private houses, are very popular today. If you are planning to get your own home, then using a SIP panel will be an excellent choice, which will allow you to build a warm and comfortable building, while construction costs will be significantly reduced. Such buildings are lightweight, which eliminates the need to build a full-fledged foundation. After completing the arrangement of the walls, you can begin interior or exterior decoration.

Our company took part in the REN TV program “Honest Repair”, which talks about SIP panels and their characteristics - watch the video:

Description of SIP panels

First, you need to get acquainted with the features of this material, which will allow you to make the right choice by using one or another type of sandwich panels for construction. Subsequently, by choosing the right material to use, it will be possible to avoid any mistakes and problems with the constructed house.

SIP panels are a multilayer structure that consists of two OSB boards, inside of which there is a thermal insulation layer of polystyrene foam. In the manufacture of such material, environmentally friendly polyurethane glue is used, which firmly connects the materials to each other, ensuring their maximum possible strength. Modern technologies make it possible to produce panels that can withstand pressure of 12 tons. On sale today you can find two types of slabs, which are intended for the construction of walls and the formation of floors.

Material characteristics

97% of SIP panels consist of environmentally friendly oriented strand boards. This material is laid in several layers, and subsequently glued with a special resin, in which the wood does not lose all its useful properties. To ensure excellent thermal insulation and strength of the material in SIP panels, numerous layers are arranged in the opposite direction, which ensures the durability of the material. Special treatment of SIP panels makes it possible to increase their resistance to rotting and deterioration of characteristics when the material is exposed to ultraviolet radiation in sunlight. We can confidently say that this is an ideal material for the construction of private houses.

Features of the internal component

Inside the panel there is polystyrene foam, which consists of 98% air and 2% synthetic materials. This is an environmentally friendly and non-toxic material that provides excellent thermal insulation and at the same time has minimal weight. Today, expanded polystyrene, as a modern material, is used for internal and external insulation.

Main characteristics of the erected structures

Professional specialists are responsible for the development of projects for the construction of residential private houses from SIP panels. However, nothing prevents you from planning and building a country house from this material yourself. Standard sizes of sandwich panels are excellent for private construction, which allows you to save on the services of professionals and do all the work yourself. The height of the sheet is usually 350 centimeters and the width is 63-150 centimeters. The thickness of SIP panels, depending on the specific modification, is 5-23 centimeters. It is necessary to choose certain types of material and their dimensions depending on the structure being built. The popularity of this material is largely due to its versatility and light weight, which not only allows you to save on arranging a full-fledged foundation, but also makes it possible to build on marshy soils, where it can be difficult to use other materials and construction technologies.

We offer SIP panels produced by Kalevala
Kalevala composition: OSB-3 Kalevala ECOHOUSE Russia emission class E 0.5, glue – TOP-UR (Russia), expanded polystyrene – PSBS – 25F (Russia). Own production.

SIP panel Kalevala Dimensions: 2500x625x174 - 2500x1250x124 - 2800x1250x124 - 2500x1250x174 - 2800x1250x174 - 2800x625x174 - 2500x1250x224 - 2500x1250x 224 -2500x625x224 - 2800x1250x224 - 2500x1250x224 - 2800x625x224

A standard house made of SIP panels, the area of ​​which is 150 square meters, will weigh 15 tons. Whereas a similar brick structure will have a mass of 60 tons, which will invariably increase the load on the foundation, and will require the presence of soil on the site with the appropriate bearing capacity. The light weight of the material should be taken into account when choosing a specific type of foundation, which allows the homeowner to somewhat reduce the cost of construction work.

Reviews about thermal insulation characteristics and strength

Excellent thermal insulation characteristics, strength and durability are one of the advantages of such a coating. The load resistance is largely due to the three-layer construction, which allows one square meter of slab to withstand a weight of 10 tons. The lateral load is about 2 tons per square meter.

When SIP panels are exposed to loads with vertical bending, the slabs are compressed, and when exposed to horizontal pressure, they are stretched. This ensures the strength of the material, which is protected from cracking and damage. Panels and walls of a house made of this material can withstand significant longitudinal loads, and the maximum lateral load is 2 tons per square meter of surface.

The existing excellent resistance to bending of the walls of the house allows it to easily withstand strong gusts of wind, which makes it possible to build such construction in climatic regions with hurricanes. Buildings made from this material are distinguished by excellent strength, and the ceilings of SIP panels can withstand pressure of 150 kilograms per square meter.

Houses built from SIP panels have excellent thermal insulation characteristics. Even if you live permanently in such a house, you do not need to additionally insulate the walls. In this case, it is necessary to correctly select the thickness of the material that will be intended specifically for the construction of residential buildings. In terms of its thermal insulation performance, a standard 12-centimeter panel is comparable to a 2-meter-thick brick laying.

Reviews on fire safety

SIP panels are a modern material that is completely fireproof. When making the coating, it is treated with various fire retardants, which increases fire resistance. Even if there is a fire, the panels quickly extinguish on their own, and in terms of fire safety characteristics, plastic is seven times better than wood. This property makes it possible to use such a coating for the construction of residential prefabricated structures.
Our company conducted its own fire resistance tests - watch the video

Positive characteristics

The material production technologies used make it possible to achieve numerous positive characteristics of the coating, which makes SIP panels popular in low-rise private construction. Accelerated construction technology can significantly reduce the construction time of structures, so a private house can be built turnkey in three months. By choosing the right construction project and subsequently strictly observing all documentation requirements, you can build a durable and reliable house that will provide maximum living comfort.

Canadian SIP panels are very popular today, allowing the use of a lightweight frame that perfectly transfers the weight of the coating to the ground, reducing the cost of building a house. Sandwich panels are completely environmentally friendly materials, so such houses will be completely safe and comfortable to live in.

What attracts you about sandwich panels?

If you plan to use such material to build a private house, then you need to make sure that a number of construction works can be completed by you yourself. Otherwise, you should contact professional builders who offer turnkey construction services. The cost of houses made from SIP panels will depend on the material used and the area of ​​the building.

Features of building finishing

You can begin finishing work immediately after completing the construction of the walls of the house. This material is not subject to shrinkage, which subsequently eliminates any deformation and eliminates the need to carry out expensive re-repairs in the house. Products may be exposed to moisture and sun, so the finishing of the building must be started as quickly as possible after the walls of the house have been furnished. The panels are covered with siding, covered with plaster or other protective facade materials. The cladding carried out can provide additional heat and sound insulation, improving the appearance of the constructed structure.

Choice of cladding

The choice of finishing materials for houses built from SIP panels will depend solely on the overall construction budget. When choosing such a material, you need to pay attention to fire safety during finishing and other characteristics of the finishing material you choose. Vinyl siding is very popular, which simultaneously combines low cost, durability, and attractive appearance. This type of finishing will be an excellent choice for houses built from SIP panels. The combination of PVC siding panels of various shades looks original, which will give the architecture of the house an unusual appearance. You can also use polymer panels that imitate brick, natural stone and wood as finishing materials. This material is distinguished by its quality and low cost.

Cement-brick panels made of cement with the addition of sand and dyes are used. However, such material has certain disadvantages. This is, first of all, significant weight, which leads to a slight increase in the load on the foundation. Cement-brick panels will have a higher cost than siding, which increases the cost of construction work. However, the attractive appearance of such a coating completely eliminates the existing disadvantages. Modern material does not fade or become cracked.

Disadvantages of SIP panels

Like any other technology and building material, SIP panels will have certain disadvantages, knowledge of which will allow you to correctly select the specific project according to which the house will be built.

SIP panels - stands for structural insulating panel, is a building material consisting of two panels of pox (or other material) at the edges and insulation between them. The material from which the boards are made and the insulation are glued together using glue under a certain pressure.

SIP panels as a building material were invented in the USA in the 30s of the 20th century, by American engineers, in order to minimize the cost of heating and insulation of buildings, as well as reduce the cost of construction. Such a simple development was appreciated by manufacturers of building materials and the panels began to be mass produced and modified. Nowadays, the technology for the production of sip panels and the construction of houses from sip panels has been brought to perfection and at the same time does not cease to improve and develop.

This technology is firmly entrenched in Canada, where the issue of insulation and energy saving is especially relevant, and is widely used to this day. Therefore, in the world, the technology of building houses from sip panels is known as Canadian construction technology. This technology is especially widespread in places with harsh climatic conditions, where low temperatures prevail most of the year, which makes it difficult to build houses from common materials.

Types of SIP panels

SIP technology is constantly being refined and evolving to suit certain construction conditions, and to be more precise, the combinations of materials of the main slab and insulation change, but the principle of forming the slab itself remains the same - two slabs and insulation between them.

Depending on the purpose, sip panels are manufactured separately for ceiling installation, sip panels for wall installation, sip panels for construction of internal partitions of a building and roof. However, they differ in thickness, weight and size.

Sip panel made of OSB and polystyrene foam

OSB– means oriented strand board, consists of compressed and glued wood chips.

This is the most common type of SIP panels; it consists of a bundle of OSB boards and polystyrene foam as insulation. This vulture board has maximum strength and high functional qualities. Due to its light weight, it is easy to install, high quality and lasts a long time. It is mainly used for the construction of residential buildings and outbuildings.

Sip panel made of OSB and polyurethane foam

This type of sip panel consists of a combination of OSB boards and insulation – polyurethane foam. They are used both for the construction of residential buildings and industrial buildings and their elements

Polyurethane foam is a synthetic substance with a cellular structure and is a hardened polymer foam.

Properties of sip panels made of polyurethane foam:

– does not burn or melt; under the influence of high temperatures, which create extreme conditions for the material, polyurethane foam is converted into a liquid mass and drains without ignition

– the thermal conductivity of polyurethane foam sip panels is 2 times better than that of polystyrene foam sip panels

– prevents rodents and insects

– due to the closed cellular structure, it does not absorb moisture, that is, it is completely moisture resistant

– environmentally friendly for humans, does not produce fumes harmful to health

– durable, the manufacturer gives a guarantee of 50 years of material service

– not much, but more expensive than a sip panel made of OSB and expanded polystyrene

Sip panels made of OSB and mineral wool

This type of sip panel is built on the same sandwich principle, only polystyrene foam is replaced with mineral wool, which acts as insulation. This version of the sandwich panel has both positive and negative sides. The positive aspects are that mineral wool is vapor-permeable and is a breathable material that also perfectly retains heat indoors, unlike expanded polystyrene, which is completely vapor-proof.

Negative aspects of sip panels made of OSB and mineral wool:

– due to the specific fleecy structure of mineral wool and the strength of the connection between the OSB board and mineral wool is questionable, that is, the insulation shrinks and settles over time at the base of the board;

– due to the weak rigidity of mineral wool, the sip panel design itself does not have acceptable strength properties

This is a standard sip panel design with mineral wool and was created and used in the Russian Federation.

Fragment of a sip panel with mineral wool

The technology has the right to life, since it makes sense to preserve the properties of expanded polystyrene without losing the breathable effect of mineral wool, therefore this type of sip panel is being finalized and used in construction; the above disadvantages are eliminated by changes in the composition and coating of the components of the slab.

One example is the already widely used sip panel, where mineral wool is also used as insulation, and magnetized slabs are used as slabs.

SML sip panels

Properties of SML SIP panels:

Mineral wool already has a more dense structure, and can be compacted through combination with other more durable insulation materials, but is already less breathable, but still vapor permeable:

Absolutely non-flammable

– moisture resistance, when in water for up to 100 days, the properties and characteristics of the material remain unchanged, this became known as a result of testing;

– environmental safety, also low weight;

– sound insulation is better than that of a standard sip panel with polystyrene foam;

– the gluing area of ​​the insulation layer and the board inside the structure is 100%, in comparison with a standard OSB board where the gluing area is up to a maximum of 35%.

– such walls do not need additional finishing, such as plaster or drywall. You can work directly with the surface of the panel;

– most manufacturers install cable channels in the designs of SML SIP panels;

– aesthetic appearance of LSU panels, they are white and create the external impression of a stone house.

The properties of an already modified sip panel, where mineral wool is used as insulation, were described above. When choosing a material for construction, you should distinguish between a regular sip panel with mineral wool and modified modifications, so that in the future you will not encounter negative qualities of the panel.

Sip panel made of fiberboard and polyurethane foam

This building material is a fairly new product on the building materials market. This sandwich panel consists of two fiberboard boards and polyurethane foam (PPU) as insulation between them. The properties of such a board combine all the advantages of fiberboard and polyurethane foam, we present them below:

House made of fiberboard sip panels

Characteristics of fiberboard:

– consists of 60% wood chips, approximately 39.7% Portland cement grade 500 and approximately 0.3% sodium silicate binder with a reduced concentration, the so-called liquid glass. Fiberboard is also called improved wood

– fire-resistant, does not burn, unlike OSB

Fiberboard boards

– practical for interior decoration, because due to the rough surface it has good adhesion, i.e. adheres well to interior materials such as putty and others. Lightweight, which facilitates the installation of slabs and, accordingly, reduces construction time

– easy to process and work; when working with fiberboard, the same tools are used as when working with wood; it drills and saws well.

– a fairly fragile material, susceptible to mechanical damage when dropped, it splits, in principle, like most artificial materials

Sip panel made of fiberboard and polyurethane foam in a wall section

– moisture resistance, there are two sides of the coin: in interior decoration, fiberboard should be used in rooms where the humidity is approximately 70%, which is higher than normal. However, due to its porosity, which on the one hand has its advantages, the fiberboard board absorbs moisture well, which, if it freezes inside, will destroy the board. Therefore, construction from fiberboard SIP panels should only be done in dry conditions, in the warmest and driest time of year. This drawback can be eliminated by external finishing of the facade; if the protective finishing is carried out on time, then the low moisture resistance of the material will not make itself felt

– slabs are made in different sizes, lengths and thicknesses

Fibrolite has been actively used in the European Union for more than 70 years.

The second component of a fiberboard sip panel is polyurethane foam, or PPU for short, used as insulation.

Properties of polyurethane foam:

– obtained by mixing a polyol and a polyisocyanate. The frozen foam mixture contains up to 90% gas, which ensures cellularity and creates high thermal insulation properties

– can be either soft and elastic, popularly called paralon, or densely hard but does not lose its elasticity, which is used for the production of vulture panels

– very low thermal conductivity coefficient, in comparison with a brick wall 1 meter thick, polyurethane foam performs the same function with only 30 mm of its thickness

– strong moisture resistance, not subject to structural changes as a result of temperature changes

– chemical strength

– not susceptible to rotting and eating by rodents, the spread of mold and mildew,

– environmentally friendly material, absolutely non-toxic

Polyurethane foam is a fairly new material and is rapidly gaining popularity around the world; it is used in the automotive, aviation, and furniture industries. A very good insulation material that is already used in the construction of high-tech energy-efficient buildings.

Sip panels made of fiberboard and polyurethane foam

Polyurethane foam in sip panels is used not only in combination with fiberboard, but also with OSB and other panel materials.

Sip panels made of fiberboard and polyurethane foam are used in the construction of bathhouses, garages, extensions and gazebos, walls, load-bearing structures in houses.

Pros and cons of houses made of sip panels (why they build from sip panels)

Above we looked at the most effective and popular options for sip panels and the materials from which they are made. But the main thing is how the house itself, built from vulture panels, manifests itself during operation. What disadvantages and advantages does it have for the homeowner and what surprises can it present to the owner.

Advantages of houses made of sip panels

– huge energy savings, in comparison with all types of building materials from which houses are built. This is one of the biggest advantages of Canadian technology.

Sip panel does not light up

– high heat savings, sovereignty can be called the first big plus. As proven by time and the operation of vulture houses, at low temperatures in the winter season, the temperature inside such a house is by 3-5 degrees Celsius per day. Given this thermal efficiency, you can safely use an electric heating system in your home.

– creates a thermal effect inside the house, in the summer it maintains a cool microclimate in the room, thus you can use split systems and air conditioners less often, which again results in savings on electricity consumption, albeit insignificant

– the properties of the material, namely its lightness, ease of processing and installation, allows you to build a house in a short time

- thanks to the low overall weight of the house, that is, there is no need to build a massive and expensive foundation for such a house. Houses made from sip panels can be built on shallow strip, pile or column foundations, otherwise this again saves your money

– the flammability is lower than that of wood; the materials of the slab are treated with special solutions that prevent the slab from catching fire. Sip - a stove made in accordance with all state standards, with the observance of technologies like in Canada, it is not possible to set fire even intentionally, all the talk about the lightning-fast ignition of the material is rather from the field of anti-PR

– houses made of sip panels are earthquake-resistant and resistant to hurricanes and strong winds, well suited for construction on unstable and problematic soils

– not subject to shrinkage, with the rare exception of extreme soils, therefore the façade can be finished and the roof can be completed immediately after installation of the house

– due to the small thickness of the walls, in comparison with the same brick, the internal area of ​​the house increases

– low cost of construction compared to the use of other building materials

Disadvantages of houses made of sip panels

– Sip-Houses still have fairly good flammability, although the materials are impregnated with special compounds, but they do not provide one hundred percent protection from high temperatures and complete protection from fire. However, the flammability of sip panels is much less compared to wood. If you properly install wiring and sockets, avoid overloading electrical networks, that is, follow basic fire safety rules, some flammability of sip panels will not make itself felt

– thermal effect vulture – on the one hand, this is an advantage of the house, but on the other hand, it is a disadvantage, which is that it is necessary to build additional ventilation; ordinary ventilation of a frame or brick house will not work here. And insufficient ventilation naturally leads to the formation of mold, condensation, and simply a lack of oxygen

Inside a house made of sip panels

– the walls of the house do not accumulate heat, only the air heats up. When doors and windows are opened for a short time, the room cools down very quickly. Compared to a stone house, which takes a long time to warm up, but accumulates heat and does not cool down so quickly. This disadvantage can be minimized by using heat-intensive materials in the interior decoration of walls and floors and still monitor the windows

A conscientious manufacturer impregnates the sip panel with water-repellent agents

– the facade of a house made of sip panels cannot be left for a season without external finishing and a full roof, this will inevitably lead to the accumulation of moisture and dampness in the walls with a further loss of strength of the materials and rotting. Therefore, when building a house from sip panels, it is immediately necessary to plan and install the external façade finishing, otherwise all efforts and resources will be wasted

The main mistake in building a vulture house

– it is strictly prohibited to build a house from vulture panels in a constantly damp climate, as well as to use raw materials during construction. You should not start construction in damp or variable rainy seasons, because vulture slabs absorb moisture well, otherwise your house will rot before your eyes and the money will be wasted. This rule is often neglected by many SIP developers, wanting to fulfill the client’s order faster. They are ready to build even in the rain. It is advisable for the future homeowner to monitor the quality of materials at the site and the storage conditions of sip panels at the site, as well as in what weather conditions the developer installs the house!!!

If you conscientiously follow Canadian construction technology, a sip panel house will delight you with its low cost, practicality and unique properties.

It is not possible to give an unambiguous recommendation on what type of sip panels a house should be built from. When choosing this or that type of sip panel, you must proceed from the climatic conditions in which you are going to build the house and for what purposes the building will be used, what weather and static loads it will endure. The variety of modern building materials and their combination in construction already allows us to meet all the needs of the future homeowner and construct buildings in any climatic conditions.
