Do-it-yourself sip panel house. We are building a house from sip panels: construction technology, pros and cons. Roof and wall panel connections

Deciding to build a private house yourself, often the emphasis is placed not so much on the quality of materials, but on their cheapness. Currently the most profitable and quick way construction— construction of houses from sip panels.

Panel construction gained popularity more than 50 years ago. Initially this technique has proven itself in Canada, Europe, Japan. Today the technology has gained many supporters among Russians.

Types of material: what are they made of?

SIP is a structural insulating panel consisting of two special sheets, between which insulation is placed.

Layers stick together under the influence of the press with high pressure. Standard thickness slabs are 9 mm or 12 mm.

Let's figure out what sip panels are made of?

Outer layers can be made from the following materials:

  • oriented strand board;
  • sheet of gypsum fiber or plasterboard;
  • plywood;
  • fiberboard board.

The following is used as insulation:

  • expanded polystyrene is a porous material that is 90% air and is absolutely safe;
  • polystyrene foam - waterproof, but flammable and prone to rapid combustion;
  • polyurethane foam - has a high insulation threshold, does not conduct heat, is flammable;
  • mineral wool- burns poorly, is safe for health.

Advantages and disadvantages

Sip panels have significant advantages:

The disadvantages of structures made from sip panels are the following:

  1. Unsafe- primarily depends on the quality of the materials used in production. Many factories make panels using foam plastic. It’s better not to buy them; polystyrene foam emits formaldehyde.
  2. Condensation forms at the junction of the frame and the slab, which leads to the appearance of joint defects.
  3. The panels are sealed, therefore buildings need forced system ventilation, which increases the cost.
  4. Service life is limited. The structure loses its insulating properties after just a few years. This problem can be solved by replacing worn-out insulation with more durable polystyrene foam.

How to build a house from sip panels with your own hands?

Today in the construction market a huge number of companies are building houses from sip panels. Of course, you can assemble the house yourself.

Let's consider stage-by-stage execution of work. So, we are building a house from vulture panels with our own hands.

Preliminary work

At this stage, a project for the future home is drawn up. Usually, suitable option choose from a variety standard projects and modify it independently.

Or ask for help at design organizations. A thoughtful layout will ensure quality and durability of the future home.

Then it is produced calculation required quantity material, purchase quality instrument(you will definitely need a screwdriver and a hacksaw). You will most likely have to resort to the help of a specialized organization.

Purchasing standard panels and then customizing them to fit your project is quite labor-intensive. Hence, It’s easier to contact a company that will manufacture and deliver the panels required parameters.

Construction of the foundation

Most Popular foundation types are:

  • pile or pile-tape;
  • monolithic slabs with shallow recess;
  • columnar or columnar-ribbon;
  • tape recess with plinth;
  • tape deepening.

Installation of piles characterized by a relatively low installation speed, simplicity, efficiency and economy. Most experts consider piles the most acceptable basis for a panel house.

A screw pile is a metal tube with a blade. The pile is screwed into the ground quite deeply, which eliminates deformation of the building.

Water supply, heating and electricity for the future home diluted to the construction of the foundation.

Waterproofing, piping, wall construction

At this stage, two layers of roofing material or bitumen are laid on top of the foundation, and then a strapping beam, pre-treated with an antiseptic. Then the starting boards are attached to the strapping beam with screws.

Next, the panels are laid, which will later serve as the floor. When joining, the grooves are treated with sealant and fixed with self-tapping screws. Ends also treated with sealant, covered with boards.

The sip panel is attached to the starting board. It should be mounted from the corners of the structure. The connection is made simply, the groove is inserted into the ridge, the fasteners are reinforced with screws.

It is necessary to use a level so that protect the structure from distortions. Polyurethane foam is used for joints. It is also worth doing with the ends of the sip panels before joining them to each other.

Construction of a full-fledged house based on SIP panels

If you have been searching for the optimal opportunity to build a warm house Without spending a fortune, consider the process of building a home from SIP panels. Pricing for the purchase of materials for the construction of a “box” measuring 10*10 square meters, excluding finishing materials- approximately 17-20 thousand US dollars. At the same time, take into account the fact that additional insulation of the building in your case will not be required.

SIP panel - characteristics and properties

The construction of houses from vulture panels began in the 2nd half of the 20th century in Canada. Technological techniques Such construction is very simple; the construction of buildings will require relatively little time (two weeks). The time spent on construction depends on the chosen project and its degree of complexity. Cheaper this method there can only be a frame house.

A house made of vulture panels, based on its structure, has a sufficient level of strength. In English, panels are called SIP, which is essentially a construction abbreviation: Structural Insulated Panel. The translation of this abbreviation has the following content: “Structural Insulated Panel”. Based on this, the Russian variation of the abbreviated name KTP. In reality, the Latin alphabet is replaced by the Cyrillic alphabet. As a result, we have the name “SIP panel”.

This material is formed from a pair of OSB boards, between which there is an expanded polystyrene layer. In the end, we have something like a sandwich. This is where another name for the slab material comes from - sandwich panel.

House made of sip panels

There are two ways to build a house from sip panels:

From lining up frame base. When building a private house, you can use timber as a basis; when building high-rise buildings, the frame is most often made of steel.

With this technology, the panels are connected using timber of different diameters.

Frameless technique involves connecting SIPs using thermal keys - inserts made from panels of small thickness.

In our country, the first option has gained the most popularity over the years. A wood frame can give the structure an additional level of strength. The load-bearing function of sandwich panels, even without the use of a frame, is sufficient for the construction one-two-story houses in the private sector. But the realization that the foundation of the house is timber somehow calms the residents. This technology has another advantage, namely maintainability. If difficulties arise, you can dismantle the damaged panels and replace them with new ones.

Houses made of sip panels for permanent residence

Advantages and disadvantages of SIP panels

Like every technology that is progressive for our environment, the construction of buildings from SIP panels has a whole range of opponents and supporters. Opponents consider the fundamental argument to be the unnaturalness of the raw materials used and the likelihood of environmental contamination with harmful substances. Indeed, this material consists of OSB and ordinary foam. Polystyrene foam is very standard material and is dangerous only when burned. OSB has also been on the market for a long time; it is produced from compressed coarse shavings. Formaldehyde-based resin compounds are added as binding elements. This is actually what causes all the criticism: formaldehyde is a poison and its presence in the atmosphere can cause poisoning.

The percentage of formaldehyde present is regulated by such a structure as the SES (sanitary and epidemiological station), and must be sold exclusively safe materials. So, if you want to build a house with SIP panels, you should choose the manufacturer more often. Recognized as the highest quality OSB boards, Egger company, which is located in Germany. Their formaldehyde emissions are E1 (safe level).

Glunz Agepan panels are also a good option, but they are used very little in our country. If we are talking about Russian companies, then we advise you to turn your attention to the products of the Kaleval company.

Only safe and reliable materials are used in the manufacturing process:

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

Any part of the building is adjusted to certain panels.

Why do many people choose SIP panels during construction?

Since such a house made of sip panels has a number of significant advantages:

Light weight of the structure, which means you can save on foundation work. Pile foundations are suitable for these buildings.

Low heat loss, reduced heating costs. Expanded polystyrene is an excellent insulation material, sandwiched on both sides by sheets. This circumstance makes the house very warm.

Low price per square meter.

Not long production times. A box of a house on 2 floors can be built in a month.

Complete absence of any shrinkage. There is settlement only at the foundation.

Finishing can be done immediately after collection.

In general, all the above circumstances force people to choose houses made from sandwich panels. They build houses for both permanent and seasonal residence. Based on this, even with a very limited budget, it is possible to build houses from sip panels, and successfully.

We carry out construction with our own hands

We build a house from vulture panels with our own hands using the following methods, there are two of them:

We purchase a house kit for a clearly specified project from a company that carries out this type works, and we will collect it ourselves. Not all companies can agree to this, but most offer an installation service from the manufacturer.

Buy slabs. Cut it to the size you need, and then purchase the timber; we do all this ourselves. In this case, responsibility for the quality level will fall only on you. If you have carpentry skills or you have relatives who are ready to give you some advice, you can go with this option.

Let's talk briefly about what a house kit is. This is nothing more than ready-made, coupled with a wooden beam required size and fastening elements necessary for construction. All building ingredients are numbered in a certain way. At the time of assembly, the blocks are connected in a pre-approved order. The whole process is similar to standard construction from a construction set, only for real.

A house kit is especially beneficial if all details are executed accurately.

Construction of houses from sip panels

Stages of construction work

To build a house from vulture panels, as in other things, we begin with the selection of the type of foundation and its direct construction. The optimal foundation for houses made of vulture panels with moderate ease is considered to be a foundation made from piles. This is what is used in most examples of SIP technologies.

Sometimes it is not possible to build a swaintak foundation in a specific area due to:

  • hard soils, due to expensive drilling work (rocks);
  • on unstable soils with reduced resistance to load (peat bogs);
  • in the presence of cavities.

Once the foundation is constructed, you can proceed to the construction and assembly of panels.

More recently it has become very popular to build houses with wooden frame. Nowadays there is a constant search for new and improvement existing technologies frame construction. The article will describe the stages of construction frame house comparatively new technology from sip panels.

What is a SIP panel - manufacturing process

Sip panel or, as it is also called, sandwich panel - multifunctional construction material. It can be used in almost any conditions. The cost of the panels is low, and the potential for their application is practically unlimited.

Wall sandwich panels are a three-layer material. Let's see how they are made.

How the manufacturing process of sip panels occurs - step-by-step diagram

Step 1: Selection of materials

For outer layers use durable material: fibreboards, oriented strand boards, wooden boards, magnesite plates, galvanized steel. The thickness of the slabs is 9 or 12 mm.

For sip panels, it is better to exclude the use of wood, since it is highly flammable, short-lived, and also the most labor-intensive to process. Most often, OSB boards are used in SIP panels for building houses. Recommended thickness 12 mm. For load-bearing structures they can be adapted for use in high humidity conditions.

OSB is made from wood chips, the diameter of which does not exceed 0.6 mm. The length, as a rule, is no more than 140 mm. Such shavings are laid perpendicular to each other in three layers. During the manufacturing process, an adhesive waterproof resin is added. In the future from high pressure and temperature, this material is compressed. The result is a plate with increased strength and at the same time high elasticity. Outer layer OSB boards are also waterproof. Using wood cutting tools, the slabs are very easy to saw. OSB holds fasteners due to the method of laying wood chips, therefore it is significantly different from other similar materials, where resin provides retention of fasteners.

The insulation is placed between two rigid protective layers material. For this layer, polystyrene foam, polyurethane foam, or mineral wool are used. The last two insulation materials are non-flammable. When selecting a brand of polystyrene foam, you need to pay attention to its flammability and flame decay time. The thickness of the material, depending on the thermophysical properties of the frame house, can vary from 50 to 250 mm. If mineral wool is given greater preference, then it is necessary to lay between it and internal plate parabarrier film.

When using mineral wool in SIP panels, a material is used that has a density of 100–120 kg/m³. This product does not burn and cannot spread fire. When heated, binding elements may release unpleasant odors, but, nevertheless, such thermal insulation material much more environmentally friendly than polystyrene foam. But mineral wool increases the weight of the sandwich panel. If compared with expanded polystyrene, the weight will be 2 times more. Therefore, this type of insulation is rarely used in sip panels. The choice of this material is also negatively affected by the high cost. The use of mineral wool as insulation in a house made of sandwich panels can cost 1.5–2 times more.

For mass production, polystyrene foam with a density of 25 kg/m³ (PSB-S-25 or PSB-25) is used in sip panels. Due to its lightness and low cost, this insulation is very popular. It is 98% composed of carbon dioxide. Due to this, it has low thermal conductivity and, accordingly, high thermal insulation properties.

This material has fairly high strength and is resistant to fungus and moisture. But mice love to gnaw out nests in polystyrene foam, in which they then settle. The purpose of this material is, first of all, external insulation walls The thickness of the insulation depends on what kind of house will be built. For permanent residence, the heat insulator must be no thinner than 50 mm. For construction summer cottage A maximum of 20 mm of such insulation is sufficient. We should not forget that polystyrene foam burns; when exposed to open flame, it melts and emits acrid black smoke. The fire safety of the structure is partially ensured by the fact that the foam in SIP panels is covered with OSB boards.

Step 2: Choosing the Right Glue

To connect all layers of a sandwich panel, the glue must retain its properties as long as the house stands. Therefore, such material must withstand different humidity, temperature changes and other unfavourable conditions. The toxicity of the adhesive after polymerization must be completely eliminated. When assembling sip panels in Canada, the USA and the EU, the following brands have proven themselves with best side: Macroplast UR 7229, Macroplast UR 7228 and Kleiberit 502.8.

Step 3: Production of sip panels

The OSB board must be evenly coated with glue over the entire surface. Then you need to lay a sheet of polystyrene foam on top of the slab. After which you will need to reapply the polymer composition and cover it with a second OSB board.

The adhesive must be applied within no more than 10 minutes. When you find of this material In air beyond the specified time, polymerization begins. The glue foams strongly and increases in volume. In this case, it is necessary to press the glued elements within 18 tons. This is realized using a powerful press. Glued wall sandwich panels must be kept for 2–3 hours. The glue dries completely in 15–30 hours. After which the protruding edges of the insulation must be cut off.


What will the foundation be like?

Prefabricated frame houses sip panels They are quite light in weight, so a reinforced foundation is not needed. For similar buildings it is advisable to use shallow foundation. In addition to this option, the pile, columnar or slab type of frame house base is also used in construction practice. Eg, pile foundation can be done in any season of the year, in any weather. Its installation can be done in as soon as possible, large financial costs will not be required. There is no need to carry out painstaking land work.

For a frame house where wall panels are used, we recommend using one of the most popular and classic options supports - strip foundation. To do this, you will need to mark the construction site. Then dig a trench 50–60 cm deep. The width can be made 40–50 cm. In the next step, you will need to make a sand and crushed stone cushion of 20 cm, which must be compacted.

Then you can begin installing the formwork. Boards 10–15 cm wide are suitable for this. As an alternative, moisture-resistant plywood can be used. It is imperative to make the formwork 50 cm above the soil level.

Next, the reinforcement frame is connected. For this, rods 10–15 mm in diameter are most often used. After this, a concrete solution is prepared. A concrete mixer will significantly speed up this process. It is necessary to regularly tamp the mortar poured into the formwork using a vibrator. This action will remove air bubbles from concrete mixture, making the created foundation stronger. When all the pouring work has been done, the concrete solution must be allowed to sit and gain strength. Experts recommend that the foundation stand for 3-4 weeks before the walls are erected.

Installation of frame and floor - what you need to know

This process begins with attaching a wooden frame belt to the foundation. The cross-section for such timber is most often used 250x150 mm. In the corners, the wall boards are connected to each other using grooves. Anchors, as a rule, are used 10–12 mm in diameter, and their length should be 35 cm. They need to be installed at a distance of 1.5–2 m from each other. In the corners it is better to use two anchors. The bolt heads must be recessed.

Tricks of building walls

Wall elements are installed after securing the guide boards to the strapping beam. Their size depends on the thickness wall panel. Such boards must be laid taking into account a distance of 10–12 mm from the edge of the beam. It is imperative to maintain strict horizontality. In order to fasten them, you will need 70x5 mm self-tapping screws. It is better to make indents between them 35–40 cm.

In the corners there are two wall frame panels are installed by placing them on guide boards. The grooves must first be foamed. Using a level you need to perform vertical and horizontal alignment. After this, you need to screw the sandwich panels with self-tapping screws to the guide boards. The fastening step is required to be 150 mm. The panels also need to be fastened together. For this you will need boards with a cross section of 50–200 mm. They are installed between two panels. To make a reliable fixation, you will need 12x200 mm self-tapping screws.

No matter what anyone says, unification has always had a positive effect not only on the speed of production, but also on its cost. AND building sector- not an exception. Unification in frame housing construction led to the development of SIP panels and similar enlarged building materials.

The SIP panel itself was invented in 1935 in the USA; insulation was first glued into it in 1952. Since the early 60s of the last century, it began to be mass-produced, which influenced the reduction in the construction time of houses and their price in America, and then in Canada. SIP panel technologies came to Russia in the late 90s.

And this procession, unlike the United States, where tens of millions of square meters of such housing are built annually, has not yet become triumphant, and its cost is 30-40% higher than abroad. This is partly due to the mentality of our developer, partly due to the high cost of components imported from abroad, the prices of which are used by rare domestic producers who have mastered the production of similar products. But once upon a time, before releasing our own semi-truck, we also purchased a batch of Ford trucks.

What does a SIP panel consist of and how is it produced?

The design of the SIP panel is extremely simple, which means it is easily repeatable, but the copyright holders and patent holders will not miss theirs, so they factored their interest into the cost of the equipment for its production. And the essence of the technology is to glue between two sheets of OSB (oriented strand board - OSB) a polystyrene foam block PSB-S-25, where C is self-extinguishing, and 25 is density (from 15 to 25 kg/m3). Its thickness ranges from 100 to 200 mm, depending on the type of building and the climatic zone where it is being built. Also, thinner panels can be used in the construction of partitions inside a frame house from SIP panels. Along the contour of the panel there are grooves for connecting and fastening bars. It must be said that panels with 100 mm insulation in terms of thermal conductivity correspond to approximately a one and a half meter wall made of solid burnt clay brick, but according to the current Russian standards for middle zone you need 120 mm polystyrene foam. Therefore, most manufacturers of SIP panels offer standard products with 140 mm PSB-S-25 and OSB thickness of 10 - 12 mm.

Making SIP panels with your own hands

It is best to cut polystyrene foam with a nichrome string, which you should use D.C. from an adjustable transformer (parameters are selected depending on the length and thickness of the wire). The charger can act as a charger car device or welding machine.

In the manufacture of SIP panels, a single-component polyurethane glue. On standard equipment, it is applied using 4 dozen nozzles for greater uniformity of distribution. The gluing process itself is carried out under pressure. For this purpose, either vacuum or mechanical presses are used. The number of panel blanks in a stack and the number of glued stacks depend on the parameters of the press.

At home, it is not difficult to make a SIP panel with your own hands. From the entire chain of technology, it is necessary to highlight only one process for explanation - applying glue and suggest pressing parameters. The rest is not difficult to implement, and a thinking person will also create a couple of devices for the relative positioning of the panel components.

So here's how to apply the glue. Choose almost any polyurethane balloon adhesive for polystyrene foam (the better known one), take a paint sprayer with an upper tank and a 2.5 mm nozzle. From an old professional spray foam gun, unscrew the assembly for connecting cylinders with ball valve. Immediately make sure that it is working properly or clean it with a special washing liquid. Make a simple adapter with the appropriate threads and connect them together. Connect to the compressor and get a uniform layer of glue (or foam) adjustable in thickness.

To be fair, it must be said that ordinary professional polyurethane foam will work no worse than glue, but will require a little more skill from you. The grooves in SIP panels are made with a depth of 25 to 40 mm, while the lower and upper trim boards will have exactly this thickness, and the connecting beams will be twice as thick.

Place the resulting sandwich under an evenly distributed load at the rate of 15 - 20 kg/m2 and leave for a couple of hours. The standard panel has an area of ​​3.11 sq.m. The load can be several wooden beams. As panels are made, add them to the stack, moving the load to the top one - the newly made one. The main thing when laying is not to move the sheets. Tip: Cut 6 pieces of board to the appropriate width and use them as templates during assembly, joining with self-tapping screws.

You will be able to fully use your SIP panels the next day.

On what foundations are SIP panel houses assembled?

Such houses can be mounted on any foundations and here main role should not be carried out by the type of frame formation (in this case it is platform, American, Canadian, pallet), but by the condition of the base - the soil. It is understandable if you have swampy soil, the area has complex terrain or is located high groundwater, we will recommend screw piles with powerful wooden bottom trim, or a platform immediately formed on its basis.

If you have soils subject to large frost heave, make a well-insulated floating foundation. It will also serve as a platform on which you can directly install SIP panels by securing the installation board with anchors, which partly serves as the bottom trim.

Under standard conditions, a grillage on poles is best suited for this type of frame.

Floor panels can be assembled directly on it, having previously treated them with a primer. In addition to sufficient strength for such a foundation, there will be one requirement when choosing SIP panel construction technology: ensuring good ventilation of the underground space.

SIP panel assembly technology

The connection of SIP panels to each other is carried out by gluing on polyurethane polyurethane foam timber, evenly fitting into their grooves. Fastening of panels to a floor or ceiling platform is also carried out using a tongue-and-groove system, with the role of a tenon being performed by the boards of the bottom and top harness appropriate sizes.

The bottom board is also called the installation board. Its thickness can be from 25 mm to 40 mm. Corner connections are made according to the same principle, only the installation board is attached to the vertical panel.

As a rule, its thickness is half the thickness of the connecting beam. Fixing parts at seams is most often done using wood screws, less often with a nail gun. The design of a SIP-panel house is so durable that for the lower and upper trim, as well as corner connections A 25mm thick board is enough.

If you decide to make SIP panels with your own hands, and we tried to convey to you that this is not so difficult, then we hope that you will make the panels of specific sizes and configurations, with ready-made connecting nodes, and you will not need additional trimming on the site. But if you find it more profitable to buy ready-made panels from the manufacturer, we recommend ordering them to be cut for your project. Many companies sell house kits.

To cut standard SIP panels yourself, you will need at least a large grinder with 230 mm disks, or the same manual one Circular Saw, long thin sharp knife for cutting and a simple device for cutting out foam plastic with a nichrome string (see photo below). Expanded polystyrene is cut to a little more than half the thickness of the connecting beam.

Time frame for assembling a house made from sip panels

Assembly one-story house 2-3 people can easily make SIP panels; it is better to make panels together. The weight of a standard SIP panel with dimensions 2500 x 1250 x 160 is 43 – 44 kg, and with a thickness of 164 (OSP-12) – up to 50 kg. Floor and roof panels are often made longer and narrower for rigidity, or additional beams are glued into them during manufacturing.

From practice, two strong men on the first floor can handle a panel with dimensions of 1250 x 5000. Above that, helpers are needed. Attic or two-storey house assembled by 4 people with the involvement of 2 helpers for a couple of days, if you do not use lifting and transport mechanisms.

And if you have cozy place for the production of SIP panels and a site for their temporary storage, then of all the frame house building systems, this is the most optimal, believe me from experience. A 100-square-foot house without any special architectural frills can be assembled by a team of the above-mentioned composition in a maximum of a week, with measured work in compliance with hourly standards. labor legislation. And if it is you personally and yours will help you Good friends or relatives, it will take even less time. And you can adapt to the weather.

Below is an accelerated video of the assembly of a house from sip panels - it’s very interesting to see how it looks from the outside.

Dear readers, if you have any questions, please ask them using the form below. We will be glad to communicate with you;)

Technology frame construction strongly associated with high speed construction of houses, their efficiency, variability in the selection of materials. One of the most practical options are SIP panels (SIP panels). Based on translation from in English, they are often called thermally insulated, structural. What distinguishes them from sandwich panels and how to properly build frame houses from SIP panels?

SIP panels - what is it?

SIP panels are one of the modern multilayer materials which is used in construction residential buildings. Their operational properties due to the special structure and manufacturing method.

Three-layer SIP structure

SIP are three-layer construction panels that are made by pressing. As a result, the material is almost seamless. The first layer is oriented strand board (OSB), the second is polystyrene foam, the third is another OSB.

Oriented strand boards are made from several layers of wood chips, which are bonded together with synthetic resins. They are pressed at high temperature and pressure. In each layer, the chip direction is different, which gives the finished sheet high strength.

Please note: than more quantity chip layers and the better the adhesive composition, the higher the moisture resistance and strength of OSB.

Oriented strand boards have stable dimensions, provide excellent noise and heat insulation, are resistant to temperature changes, and are easy to install.

Expanded polystyrene consists of individual microporous granules, inside of which there are voids. They determine the lightness of this insulation and its good soundproofing properties. Expanded polystyrene does not release toxic substances into the air, is frost-resistant, and resistant to mold.

The advantages of these two materials largely determine the advantages of construction from SIP panels.

Sandwich panels and SIP panels - what are the differences?

It’s worth mentioning right away that at its core, SIP is a type of sandwich panels. It is characterized by: a combination of OSB and expanded polystyrene, a certain set of performance qualities.

There are other sandwich panels:

  • casing: galvanized steel with polymer coating, rigid PVC sheets, plasterboard, chipboard, ;
  • thermal insulation: mineral wool, .

The general prefix “sandwich” only means multi-layered material.

The manufacturing technology also distinguishes SIP from other sandwich panels. Densely compressed into monolithic sheets they are superior to analogues made from other materials. But most sandwich panels can be easily disassembled into layers.

Concerning bearing capacity, then SIP can be structural elements houses, to bear the vertical load from floors, roofs, etc. Sandwich panels are more suitable for internal partitions, additional insulation external walls.

Advantages and disadvantages of the material

Equipped houses made from SIP panels are different high level heat saving. They can be almost 1.5 times warmer than similar buildings made according to standard frame technology. This allows you to reduce energy and heating costs.

Inside the building is formed favorable microclimate. During cold weather, the air in the rooms quickly heats up, but takes a long time to cool down.

To build a warm “box” at home it will take literally 10-14 days, regardless of the time of year. And upon completion of the work, you can immediately begin finishing, since the walls practically do not shrink.

Also, insulated panels in most cases do not need additional steam and wind protection.

Their disadvantages include: high cost when using high-quality OSB, flammability of wood and the “thermos” effect. The latter implies the need to install forced ventilation under conditions of an almost closed thermal circuit.

How to build a house from “warm” panels

Building a frame house from SIP panels with your own hands is not difficult. Not the least role in this is played by the relative lightness of the material and its strength.

The sequence of work will be as follows:

  1. Carrying out earthworks to determine soil quality.
  2. Marking the foundation and laying it. Due to the lightness of SIP, it can be a budget tape, pile or screw option.
  3. Construction of the lower tier of the building (subfloor). The slabs are laid from the corner, not forgetting to make technological holes for communications.
  4. Construction of external walls and partitions inside the house. The connection of the panels should be as tight as possible, without voids.
  5. Laying of floor panels from SIP panels, construction of the second floor using already proven technology.
  6. Installation of the rafter system and its SIP sheathing.

Construction of a residential building from SIP panels saves time and labor. Instead of covering external walls and insulating them (with installation of sheathing), you only need to install ready-made three-layer material with the required set of properties.

Connecting panels to each other and to other structural elements

High-quality SIP fastening means the absence of cold bridges and ease of assembly individual parts, the strength of their connection. Each of the main structural units has its own characteristics.

Fastening panels to the foundation

To install wall SIPs to the foundation, first lay waterproofing (roofing felt) on it and secure the trim boards (BW).

After this, the floor panels are laid. They are fixed to the base using anchors. The distance between fasteners should not exceed 2 m.

Installation of this type of SIP panels occurs as follows:

  • Self-tapping screws with a diameter of 4.8 mm and a length of 95 mm connect the ceiling to the trim boards.
  • Using 3.1x50 mm self-tapping screws, fix the wall panel to the DO. The distance between fasteners should not exceed 150 mm.

During the installation process, check the evenness of the SIP fastening using a building level.

Corner connection of wall elements

In outdoor and internal corners(90°) panels are joined together using wooden dowels. Typically these are boards 50 mm thick and 150 mm wide. An alternative for building a house is I-beams.

Please note: joints individual elements first foamed with polyurethane foam.

The dowel is attached to one of the walls using self-tapping screws 4.8 mm in diameter. The distance between them should not exceed 200 mm.

The panel of the other wall is fixed to the dowel with 3.5 mm screws, maintaining a pitch of no more than 150 mm. Projecting part OSB boards fixed to the end of the wall panel in the same way.

Joining wall and floor panels

This is a complex SIP connection unit at home, which involves the use large quantity fastening elements.

  1. The floor slab is fixed to the lower wall using self-tapping screws, the diameter and length of which are 6.3 and 240 mm, respectively. The distance between them should not exceed 300 mm.
  2. A trim board is mounted on top of the ceiling. To do this, use 4.8x95 mm self-tapping screws, screwing them in increments of 100-200 mm.
  3. Using 3.5x51 mm self-tapping screws, fix the panels of the upper wall to the trim board. The distance between them should not exceed 150 mm.
  4. OSB on the floor trim board is also secured with 3.5 mm self-tapping screws. However, a step of 300 mm is acceptable.
