Sandwich panels for wall insulation. Insulation of garage boxes with sandwich panels from the inside, Ussuriysk Insulation with mineral wool

Finally, the keys to the new apartment are in your hands! And you are already calculating the costs of repairs, imagining the interior design, imagining a noisy housewarming party, and quiet family evenings in a cozy home.

But, before starting interior repair work, check how well the facades of your house are insulated. Most modern new buildings are built with mandatory insulation of facades. But you need to think about insulating an apartment in old houses yourself.

For this purpose, sandwich panels for wall insulation have recently replaced traditional materials (foam plastic).

Cladding sandwich panels are multilayer elements, the outside is lined with metal, and the inside has a layer of insulation (mineral wool, polystyrene foam or polyurethane foam), which is covered with aluminum foil.

The panels are lightweight, which is a huge plus, since often the condition of the building walls and foundation may not withstand the additional load. In addition, the surface of the sandwich panels is durable (does not lose quality under the influence of ultraviolet radiation, low temperatures, and is not afraid of moisture). There will be no additional costs for processing the panels, since they are painted in different colors and the surface can have a variety of textures.

Thermal insulation can be both internal and external. The advantages of the latter are obvious:

A structure whose facade is protected by thermal insulation material will last longer (the wall does not freeze, the effect of atmospheric phenomena is reduced), and also has a more aesthetic appearance;

Insulating walls with sandwich panels improves sound insulation and also creates a favorable temperature regime (condensation does not form, mold and fungi do not grow);

External thermal insulation reduces heat loss, and as a result, the cost of paying for utilities (with an individual heating system);

External insulation of facades with sandwich panels does not reduce the area of ​​the premises (as is the case with internal thermal insulation);

External insulation can be carried out even after major renovations have been made indoors;

The installation of a sandwich panel with polyurethane insulation, like any other panel, is best left to professionals, since it is quite labor-intensive, and if the apartment is above the second floor, it is also a dangerous process.

A qualified craftsman will assess the condition of the wall, select the appropriate material, remove the old finish and carry out thermal insulation work.

If, with the onset of cold weather, the temperature in your apartment tends to zero, then you have a choice - make all the rooms have heaters and wrap yourself in a blanket, or thoroughly insulate your living space. Let's look at the list of possible heat loss problems in an apartment in order.

Common causes of cold in an apartment

1. The first and most common reason is cracks in window frames. If you do not have the opportunity to install sealed double-glazed windows, then seal the gaps between the frames yourself. To do this, you can use foam rubber, paper or pieces of fabric. Take one of the listed materials, roll it tightly and place it in the gap between the frame and the window opening. Seal the cracks on top with strong construction tape. This will significantly reduce the flow of cold air into the apartment, but will not provide complete thermal insulation.

2. If you live in a panel house, then the second common cause of cold in the apartment may be poor-quality seams between the plates. Your management company is required to seal external seams. But, as a rule, the procedure for completing and signing an application for such work can last a very long time.

3. If you want to solve this problem quickly, you can contact a construction company that seals the seams between panels using industrial climbing methods.

4. However, even all the measures described above may not be enough to insulate a corner apartment on the 7-14th floor. Wind gusts at this altitude are much more intense, and the water in the heating system, rising from the first floor, has time to cool down considerably. Therefore, you need to thoroughly insulate not only the windows and interpanel seams, but also the walls themselves. Sandwich panels can be used to insulate walls.

5. You can fix sandwich panels on cold walls inside the apartment. This is a relatively new, but easy to process construction raw material. In addition, this is the most economical option, because... You carry out all the construction work yourself and pay only for the materials. But the thickness of the sandwich panel can reach 25 cm. This means that the area of ​​the room along the entire length of the wall will be reduced by exactly that amount.

6. If you are not ready to part with part of the usable area of ​​your apartment, you can contact a construction company, and they will fix the sandwich panels on the outside. This is an expensive procedure, but at the same time it is the only effective method that allows you to insulate an old apartment on the top floor.

For more complex and unknown reasons, it is possible to detect cold places in the apartment using a thermal imager, which can easily identify areas of heat loss. The only negative is that this device costs a lot of money, but you can call a service that will give a comprehensive answer about the cold zones in the apartment and the places where heat is lost.

Installing PVC windows is an excellent way to preserve the warmth of the interior of a living space, since plastic windows are characterized by high tightness. But besides this, to maintain heat in the house and increase energy saving indicators, it is very important to correctly perform the slopes.

This is a fundamental point. And that's why. The window frame is inserted into the opening using mounting foam, and it is not recommended to leave the foam open - it is destroyed under the influence of sunlight. In addition, polyurethane foam has the ability to accumulate moisture, which can subsequently lead to the spread of mold and mildew in the house.

Slopes are the inner walls of the niche into which the window frame is inserted. There are different methods for processing window slopes.

Making slopes is an extremely important task. The energy saving indicators of the living space and its sound insulation will depend on how well the slopes are made and what materials were used.

The simplest way to finish slopes is plastering with a plaster mixture or putty. Plastering is a very affordable method, however, it is very ineffective in terms of energy saving. Such slopes, unfortunately, are characterized by poor thermal insulation. Plaster is a fragile material and can crack over time, which leads to the need for periodic corrective actions.

To ensure good thermal insulation when making slopes, it is necessary to use additional materials in the work, due to which it will be possible to provide the insulation function. In other words, insulation is the use of thermal elements that are mounted with slopes and are subsequently plastered. Next, the article will discuss how to properly insulate window slopes.

There are two types of work for this operation:

• external works;
• internal work.

The materials used for insulating slopes are:

• drywall;
• mineral wool;
• Styrofoam;
• expanded polystyrene;
• sandwich panels.

External insulation of slopes

External thermal insulation of slopes is carried out in several approaches. First, you need to prepare the working surface - clean it of dirt, dust, foam residues, and uneven surfaces.

For external insulation, as a rule, foam plastic or polystyrene foam is used, which is attached to the working surface using liquid nails. Using perforated plastic corners in your work will help you achieve perfectly even levels.

The work process is as follows:

• gluing prepared foam sheets to the outside of the slope;
• if there are cracks, fill the cavity with an adhesive solution;
• securing the reinforcing mesh to the surface of the foam sheet;
• carrying out plastering;
• carrying out staining

The second step in insulating window slopes is carrying out internal work.

Internal insulation of slopes

1. Plasterboard insulation

A fairly common option for finishing slopes is using plasterboard.

Drywall is a material whose structure consists of two sheets of construction cardboard with a core of solid gypsum. It should be noted that this material is quite delicate, as it does not tolerate moisture well and can swell and lose its original shape. There is moisture-resistant gypsum cardboard, which contains antifungal substances and silicone granules, but when finishing it would be useful to use additional materials, for example, a moisture-resistant primer.

Insulation technology

Insulation of window slopes consists of several stages. To do the work yourself, you will need a standard set of tools: a tape measure, a painting knife, wooden blocks, a roll of tape, several
packages of polyurethane foam, as well as sealant, moisture-resistant primer and possibly gypsum plaster.

The insulation process occurs according to the following scheme:

2.Insulation with mineral wool

Types of mineral wool

Mineral wool is a popular material that is characterized by two important, linearly dependent characteristics - thermal insulation coefficient and volume. There are three types of mineral wool:

• Soft type - high insulation coefficient and large volume.
• The semi-rigid type - compressed material - takes up less volume, due to which it loses its thermal insulation properties.
• The rigid type is a thin material, but also ineffective at providing thermal insulation. As a rule, it is used only in combination with other insulation materials.

Insulation technology

The method for insulating window slopes using mineral wool is similar to the above-described technology for insulating with plasterboard, with the only difference being that it is necessary to lay a layer of the material in question between the wall and the sheet of finishing material. In order for insulation to be effective, it is necessary to take into account some nuances:

3. Insulation with foam plastic

Types of foam. Properties

Foam plastic is a whole class of polymer materials, which are essentially cellular foamed plastic mass.

In addition to the economic benefits, the advantages of the material include:

• high thermal insulation properties;
• materials are non-toxic;
• light weight of materials, ease of installation and fastening;

Compared to polystyrene foam, polystyrene will score more points, since the material is not as fragile, more flexible and durable.

Insulation of slopes with polystyrene foam. Technology

The insulation method is identical to those described above. Sheets of material are mounted on a slope using glue with further plastering or covered with sheets of plasterboard.

When insulating window slopes in a relatively warm climate region, two layers of material will be sufficient; in colder climates, polystyrene must be combined with other insulation materials, for example, mineral wool.

4. Insulation using sandwich panels

The concept of sandwich panels. Kinds

A very effective and modern way to insulate window structures is insulation with sandwich panels.

Sandwich panels are a building material with a complex structure, consisting of two sheets of rigid material (often PVC) and a layer of insulation. All elements of the material are connected by pressing - cold or hot.

According to their purpose, sandwich panels are classified into:

• roofing;
• wall – used in finishing works

The following is used as insulation in these panels:

• mineral wool;
• expanded polystyrene;
• fiberglass

The advantages of sandwich panels include:

• good thermal insulation and sound insulation;
• safety for humans;
• lack of reaction to exposure to chemical environments, as well as mold and mildew
• the gap between the wall and the sandwich material is eliminated using some kind of heat insulator, for example, mineral wool;
• the outer side of the slopes is covered with an F-shaped profile to achieve an aesthetic effect

Before insulating window slopes, you need to measure the width of the gap. It should be noted that the choice of insulation is often associated with precisely this indicator, and therefore, with a gap of about 40 mm or more, it would be more reasonable to use polystyrene foam or expanded polystyrene. If the gap is less than the specified dimensions, mineral wool is used.

Thus, insulation of slopes is an important and necessary matter. For the result to be effective, work must be carried out simultaneously on the inside and outside of the window structure.

While thinking about how to clad a house made of shell rock, covered with ordinary rough cement plaster, I decided to choose panels with insulation. Facade facing panels with insulation are a convenient and interesting option, but finishing with this material has many nuances and subtleties.

I will share my experience using the example of panels made of a cement mixture with additives of a beautiful texture, insulated with a layer of foam plastic. But first, the options that can be found in a large hardware store.

Types of panels - advantages and disadvantages

The very principle of the thermal panel design is several layers of finishing. A layer of insulation, an adhesive base and a decorative coating with additional protective functions. Today there are four sandwich options that are quite affordable.

• Clinker tiles as a decorative layer look stylish and allow you to create any facade design. In this finish, the supporting layer is made of OSB, which gives the material additional rigidity.
  For the base, it is better to choose a material that is additionally reinforced with pressed metal or plastic bushings. It's more reliable. In addition, such cladding can be installed with your own hands.

• A layer of decorative plaster on polystyrene foam - there are many options. As decoration, you can choose the addition of marble chips or quartz. The advantage of such panels is the ability to create an ideal seamless finishing surface.

The photo shows the rules for installing metal panels

• The metal coating is reliable and durable. The insulation is protected on both sides by aluminum or profiled sheets. You can choose any one - wood or stone, but it will cost more.
  The disadvantage of metal is its heavy finish; the instructions do not recommend installation on old walls without additional strengthening and reinforcement.

A concrete coating with additional strengthening additives and an interesting “torn” texture. Insulation – a layer of polystyrene foam. The most budget option.

You can buy it at mini-factories for half the price than in the store. This is exactly the finish I chose for myself. You can paint it like sandstone, marble or wild stone.

Panels for insulating the facade of a house made of pressed concrete with the addition of strengthening and water-repellent additives can be mounted on any walls with rough plaster. Ideally smooth out all the imperfections and imperfections.

Rules for cladding with any sandwich panels

Since I am familiar with many problems firsthand, I will share the main nuances that are important to pay attention to.

Rule #1

It is important to calculate the loads on the foundation and walls, especially in old buildings with shallow strip foundations. Some insulated panels for facades have considerable weight (concrete coating or metal). For clinker tiles, installation of sheathing will be required.

The architects advised under no circumstances to choose wood for the sheathing. Even treated with a deep penetration primer, it quickly begins to rot, and wood-boring beetles love it very much. Only metal lathing, like for drywall.

It is also important to consider the strength of the walls. If the building is old, then it is necessary to carry out additional strengthening reinforcement with a metal mesh and apply a layer of starting leveling plaster with strengthening additives.

If you don’t want to pay for architects’ calculations on the load-bearing capacity of the walls, then it’s better to opt for a lightweight option for exterior finishing - a metal frame or light clinker tiles.

Rule #2

Be sure to look for a professional construction crew because it will be difficult to correct poor work. This is exactly what happened to me. I hired craftsmen, they assured me that they worked with this material, but what I got was not walls - but a chessboard without worn out seams. I had to spend money on additional painting with decorative additives.

Let the craftsmen show their work, don’t be lazy, go and look at the site, talk to the owners. Nowadays there are a lot of “craftsmen” who can “do everything”, but in the end they simply spoil good material.

Rule #3

When choosing thermal panels for insulating the facade of a house, immediately think about the design concept for the entire facade. Now, for five thousand rubles, you can order sketches from a design office with different finishing options in texture and color.

Then redoing and purchasing additional materials will not only be more troublesome, but also significantly more expensive. Of the most interesting options, I can recommend inexpensive and beautiful combinations:

• Base made of metal and decorative plaster;
• The plinth is made of textured pressed cement and wood-look siding - the plinth can then be designed to look like timber or wild stone. Lots of decor options.
• Clinker tiles are very “delicate”; they are good to use as decorative inserts for panels covered with “torn” plaster.

For the basement of an old house, a brick-like metal thermal panel is ideal, and above it can be insulated with light plastered slabs.

Rule #4

Decide immediately what layer of insulation is needed. The thicker the layer, the more expensive the finish. But in some cases it is worth paying more. This applies to the basement and those walls of the house where there is the most traffic.

Here the finish must be durable and resistant to ground moisture. Metal panels, protected on both sides, are the most reliable for the base and corners.

If there are strong temperature changes or harsh winters in the region, then you should choose not ordinary polystyrene foam, but self-leveling foam. This material retains heat better and is not afraid of moisture.

Rule #5

When decorating a facade with sandwich panels, you cannot skimp on protective and disinfectant impregnations, because then you will have to replace the entire cladding.

• Before installing the sheathing, be sure to treat the walls with an antiseptic and deep-penetrating strengthening primer. The northern walls are even done in two steps, every day.
• If the lathing is made of wood, then we treat the wood with a protective primer, and in addition you can paint it.
• It is important not to forget about the organization of ventilation gaps - this applies to all materials that are attached to the sheathing, no matter whether metal or wood.
• If the site is close to groundwater, then additional waterproofing of the base is necessary. A resin or roofing material coating is suitable.

Thermal panels for insulating the facade of a house save up to 40 percent of heating costs, plus they guarantee dry walls and a comfortable indoor microclimate.

Summary

The video presented in this article describes in detail the installation of thermal panels on a metal sheathing.

I will be glad to discuss this interesting topic in the comments, and in the near future I promise a detailed article with photographs of the “masterpiece” of my craftsmen. Maybe someone will recommend an interesting painting option.

If you want to express gratitude, add a clarification or objection, or ask the author something - add a comment or say thank you!

Facade facing thermal panels are presented in the form of special structures that perform two important tasks - they insulate the facade of the house and are a finishing material.

Thermal panels - facade decorative elements

Metal and rusticated facade panels have gained well-deserved popularity due to their relatively low cost and high speed of installation work.

1 Features of facade thermal panels

It’s worth mentioning right away that the presented metal and rusticated facade panels of the Rockwool brand represent the most rational and environmentally friendly solution to the thermal insulation issue.

Before you start insulating the outer surface of your house with a product such as a façade sandwich panel, you should take into account that it can be compatible with any surface, be it stone or brick.

Insulating the façade of a house with Rockwool sandwich panels will give better results if they are secured to an additional layer of polystyrene foam.

By the way, unlike foam plastic, Rockwool sandwich panels, stylized as stone or brick, significantly improve not only the heat-saving qualities of the facade, but also increase its aesthetic appeal.

In addition, the Rockwool sandwich panel can be attached to the outer surface of the facade (as opposed to foam plastic) on surfaces such as:

• Concrete;
• Expanded clay concrete;
• Classic brick on ;
• Plastered facade;
• Unplastered facade;
• Wall of a block house;
• Aerated concrete;
• Tree;
• Unfired raw brick.

Thermal panels stylized as stone or brick have mostly positive reviews, which is associated with a certain number of advantageous features.

For example, this may be the possibility of insulating old buildings with sandwich panels. Products such as rusticated thermal panels can, if necessary, insulate the facade of a house with a broken geometric shape.

It is almost impossible to carry out such insulation work using ordinary polystyrene foam. In particularly difficult cases, in order to insulate the uneven facade of the house, instead of polystyrene foam, it is first finished with lathing, which levels the working surface.

After this, the facade is covered with thermal panels or sandwich panels, which can be stylized as stone or brick.

2 Characteristics and properties of thermal panels

When finishing the outer surface of the facade with thermal panels, the period of installation work is significantly reduced.

In turn, this significantly reduces the total time spent on construction work, and as a result, their cost.

It is known that when carrying out construction work, a significant share of the costs is not only the purchase of materials and wages, but also the rental of scaffolding, with the help of which facade work will be carried out.

Installation of a thermal panel does not require the involvement of highly qualified workers and specialists, because you can do it yourself without much difficulty.

To do this, by and large, you will need a minimum set of the most common tools. During installation you cannot do without:

• Electric drills;
• Construction knife;
• Hammer;
• Screwdrivers as shown.

Before you start installing insulation, you need to make sure that the surface of the walls is smooth and free of significant flaws.

Facade panels can be secured using glue, polystyrene foam or dowels. It is known that the presented panels cost significantly less than traditional brickwork, therefore, after carrying out simple calculations, you can find out the percentage of cost savings when carrying out insulation in this way.

The insulation, presented in the form of thermal panels, completely relieves the owner of the mandatory need associated with periodic repairs of the facade and restoration of the outer surface of the walls.

However, if the work is carried out without complying with the technology requirements, the insulating coating may be subject to deformation.

The presented material has a long service life, which is equal to more than fifty years, while maintaining the original color.

2.1 Product reviews

As already mentioned, reviews of facade panels with insulation are mostly positive.

Pavel, 45 years old, Izhevsk:

I recently purchased a country house on the secondary housing market. I decided to do a major overhaul before moving in. When it came to insulating the facade, I bought and installed Rockwool thermal panels. Excellent insulation and, moreover, pleasing to the eye.

Sergey, 50 years old, Kramatorsk:

Recently, the old heating system began to cope with its task poorly. I took up the external insulation of the facade. Rockwool sandwich panel was used as insulation. Now all rooms have the optimal temperature. I recommend this insulation to everyone.

Vladimir, 43 years old, Zhitomir:

I am the foreman of a small construction team. We work mainly on private orders. When it comes to external insulation of house facades, we use Rockwool thermal panels. These products have long proven themselves to be the best. Customers are always satisfied, the material is excellent, we have no complaints about its quality.

2.2 Clinker thermal panels

The presented type of panels has clinker tiles as a decorative layer. If we talk about the degree of resistance to aggressive environmental influences, clinker is superior in its performance to some types of natural stone.

This material has a large number of colors and is made using slate clay. Such raw materials are currently mined in Northwestern Europe.

This suggests that clinker is an absolutely environmentally friendly material that does not contain harmful chemical additives or impurities.

It is created by implementing the high-temperature firing method. Clinker panels exhibit high mechanical strength, with a low water absorption value.

This material is characterized by pronounced frost resistance and the ability to retain its properties throughout its entire service life.

In addition to the fact that clinker panels exhibit excellent thermal insulation and aesthetic properties, they demonstrate high noise insulation qualities.

In addition, the material acts as additional waterproofing. This material is used not only as insulation and a decorative element of the facade, but also for interior finishing work.

2.3 Thermal panels with porcelain tiles

Ceramic granite is another type of insulating ceramic tile. It is made from high-quality raw materials, through the process of firing, exposure to high temperatures and pressure.

The result is a very densely compressed material that is practically immune to harmful environmental influences.

These indicators are significantly superior to natural stones. The presented thermal panels are especially appreciated by those home owners who prefer to design a façade that has a detailed textured surface.

Thermal panels made from porcelain tiles are large in size, which easily allows them to imitate masonry.

As a rule, these products are used in homes whose appearance is focused on Mediterranean or Scandinavian styles. Despite the substantial size of the slabs, they weigh little, which makes it easy to install them with your own hands.

2.4 Thermal panels with glazed tiles

This type of thermal panels is currently very popular. Their use is especially relevant in the process of finishing low-rise buildings.

The popularity of this material was already noticed in the 60s of the last century. Glazed tiles are distinguished by a smooth surface and have a heterogeneous color range, which gives the facade of the house a resemblance to natural brickwork.

This material is characterized by good appearance, ease of installation, high strength characteristics and a minimum number of disadvantages.
