Insulation with sandwich panels. The relevance of the use of facade panels with insulation Is it necessary to insulate a building from sandwich panels

Hello.

Thanks again for your advice. Let's discuss the designs with you.

I want to outline the design of the Sandwich House in the Brick House.

Sandwich 100mm thick is sewn to brick wall. The wall is not even, the plaster is peeling off in some places. It is sewn in level with anchor screws as tightly as possible to the wall. Without any suspension system and guide profiles. We provide a snug fit to the wall in several places (bottom, top, middle) with the help of foam, which we apply on reverse side panel before installation. We seal the heads of the anchor screws with rubber gaskets or ordinary silicone sealant. The bottom to the floor and the top of the panels to the ceiling are foamed, the side joints (groove to groove) are also foamed, you can also silicone it all. So the entire perimeter. Window and door openings - hermetic finish, for example, with a metal sheet. From window profile to the edge of the sandwich with foaming the slopes and siliconizing the joints. On the floor (screed or tile), the plinth is screwed to the sandwich. After, in the same way, the ceiling is going. The joints to the walls foam and silicone. The top plinth is also screwed to the sandwich.

I understand perfectly well that the air will be outside the perimeter of the sandwiches. Maybe it will somehow penetrate there, but not by direct contact with the wall. He will need to make a path of 100 mm. I think that it will pass through the dew point, and it will already be cold at contact with the wall. Or will it come from the side of the bricks? Explain, please. Or it will remain there from the summer and at the first frosts it will condense in the outer layers of bricks and remain there until the end of winter. And next summer it will again be saturated with moisture. But during the winter, he doesn’t get where to come from? With this option, it seems to me that condensation will occur only once a year - in the fall. Maybe I'm wrong. It seems to me that the same thing happens in an ordinary uninsulated thick wall of 5 or 6 bricks in the outer layers to the street. Please comment.

I want to ask you about external insulation.

Is it possible to insulate the outside hermetically, for example, also with sandwiches, or with foam plastic (foam the joints). Also a House within a House, only bricks in a sandwich. How then is moisture removed from the structure itself (concrete, bricks, floor slabs)?
What will happen if there is insulation from the inside (5 cm polystyrene is sewn up with drywall in part of our room) and make insulation from the outside (hermetic).
Is it possible to seal a wall or ceiling on both sides, for example, outside insulation with foam or sandwich, and inside tile to the ceiling along the perimeter ( washing room). Or a sandwich outside and a sandwich inside (the same washing room)
Not infrequently I saw that they insulate with wool (special) and when sheathing decorative panels leave space under the crate. This is a feature of insulation with cotton wool (to remove moisture from the dew point) or for all heaters.

With inner wall from a gas block - good, but large space steals, but in fact it is the same internal insulation, and the wet will be inside the wall.

Thank you. I'm waiting for your answers.

Sandwich panels are produced by manufacturers ready for use, so the issue of finishing in some cases does not arise at all. For example, in the construction of industrial premises. The product is a three-layer structure consisting of two sheets of galvanized steel and a heat-insulating layer between them. As a heater, basalt wool or foamed synthetic materials: expanded polystyrene, polyurethane foam and others.

The front surfaces can be smooth or corrugated, coated with polymer resins. Due to this, the plates are produced in various colors, which allows you to create interesting geometric combinations on the outside of the building. Developers take advantage of this quality. industrial enterprises in order not to additionally solve the question of how to finish the sandwich panel. It's quite different when we are talking on the construction of private houses. If you can still get by outside appearance the plates themselves, then indoors they must certainly be closed.

Scope of use

Sandwich panels are used in construction frame houses, as filling between the drains and the crossbars of the main frame. They are used for exterior finish as self-design or as part of a hinged ventilated facade. This material serves as both insulation and cladding. There are special three-layer roofing products. Both those and others are equipped with all sorts of additional elements and layouts, so that during installation it was possible to close the joints and decorate the edges, corners, transitions. In addition, the products themselves are produced with thorn-groove locks, so they are easily and tightly mounted. You can attach them to the crate, and to a flat surface, if it is even.

AT recent times insulated plates began to be often used for internal works. They make internal partitions, stationary and mobile, they insulate the outer walls from the inside of the premises, as well as balconies and loggias. It has become especially popular to use sandwich panels for finishing windows, more precisely - slopes. In this case, sandwiches are used with outer layers not made of metal, but made of plastic and with a thinner layer of insulation.

Slope cladding

With the advent of plastic windows, the problem immediately arose of how and with what the slopes should be finished. We tried everything - both high-quality plaster and plastic panels and many other options. But the most The best decision came with the advent of three-layer material. Sandwich paneling window slopes at the same time eliminates "cold bridges" and gives the window opening a complete look. The work is simple and quite affordable in order to do it yourself. Facing of window slopes should be carried out before finishing the walls. These jobs are done in this order:

all surfaces around the window frame are cleaned of dust, dirt, mortar influx;
a window sill is installed; most often, a solution based on cement and lime is used for this; to avoid deflections, metal strips are laid under the windowsill, and for insulation lower part and the sides are wrapped with felt; the insulation is impregnated with an antiseptic before use to prevent its decay and the appearance of insects;
voids and junctions of the window and window sill to the opening are sealed with mounting foam; hardened foam cut with a paint knife flush with the main surfaces;
the sandwich panel is cut according to preliminary measurements of the upper part and sides; the material is cut very well with a jigsaw or a metal saw;
work begins with the upper slope: self-tapping screws are attached to the frame starting plastic profile into which the sandwich is inserted right size with a slight slope the internal gap is filled with mounting foam or liquid nails and pressed against the wall;
in a similar way, the side parts of the slope trim are fastened; care must be taken to ensure that the slopes fit snugly against the sidewalls of the opening, and excess adhesives should be removed immediately and thoroughly;
finish facing the slopes with sandwich panels by fixing the finishing frame in the form of corners on liquid nails.

There are other ways to install window slopes using brackets, battens and other fixtures. However, these methods are more complex and time-consuming. They are used in special cases when the design of a window opening or frame requires it.

From the foregoing, it is clear that do-it-yourself installation work on installing a window sill, and slopes on windows, is not such a terrible problem. Moreover, this method of protecting a window opening is successfully used not only for plastic frames but also for wood. This means that you can build a beautiful frame for a window block without changing the window itself. Moreover, manufacturers have learned how to design the front surfaces of sandwiches in the most different colors and shades, including "wood, marble, granite". Plastic used glossy, semi-gloss, matte. Cladding with sandwich boards window openings can be matched to the interior of any style.

Sandwich interior walls

The premises of frame houses, the outer walls of which are made of "sandwich" slabs, are undoubtedly subject to interior decoration. Since the panel itself inside the room will look too dull and bureaucratic. At the same time, methods and materials can be absolutely any. Only for finishing will be needed preliminary preparation. Let's say it's impossible to stick wallpaper on sandwiches. Therefore, first you have to sheathe the walls with drywall. Might have to accept additional measures for better insulation walls. For this purpose, a layer of insulation is laid between the frame profiles, and then it is sewn up with drywall sheets. This is followed by a standard procedure: sealing the joints with putty with reinforcing tape, grouting the caps of self-tapping screws and wallpapering, tiling, textured plaster, painting over the finishing putty.

Some interior styles require the presence of a large amount of wood. In this case, the owner of the house can apply his talent and sheathe the walls beautiful clapboard, timber imitation, wooden wallpaper. To do this, you need to equip the frame of the bars along the surfaces of the walls, arranging them in such a way that the cladding lies as intended - in a vertical or horizontal position. If the building was built frame version and does not require additional insulation, then it is not necessary to arrange the crate, but wooden cladding can be attached to the frame posts. All work can be done with your own hands, showing maximum imagination. The main thing is to choose materials with taste and mount them according to all the rules of finishing art.

Installing PVC windows is a great way to keep the heat in the interior space of a living space, as plastic windows characterized by high tightness. But besides this, in order to maintain heat in the house and increase energy saving rates, it is very important to competently perform slopes.

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

Slopes are the inner walls of the niche into which it is inserted window frame. Exists different techniques processing of window slopes.

The implementation of slopes is an extremely important task. From how well the slopes are made, and what materials were used, the energy saving indicators of the dwelling and its sound insulation will depend.

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

To ensure good thermal insulation when performing 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 subjected to subsequent plastering. Further, the article will focus on how to properly insulate window slopes.

There are two types of work on this operation:

outdoor work;
internal work.

Materials that are used for slope insulation are:

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

External slope insulation

External thermal insulation of slopes is carried out in several approaches. First you need to prepare the work surface - clean it from dirt, dust, remnants of mounting foam, bumps.

For external insulation, as a rule, foam or polystyrene foam is used, which is attached to working surface through liquid nails. Use of perforated plastic corners will help you achieve perfectly even levels.

The work process is:

gluing prepared foam sheets with outer side slope;
in the presence of cracks, filling the cavity with an adhesive solution;
fixing the reinforcing mesh on the surface of the foam sheet;
carrying out plastering;
staining

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

Internal insulation of slopes

1. Plasterboard insulation

A fairly common option for finishing slopes is with the use of drywall.

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

Warming technology

Insulation of slopes of windows consists of several stages. For self-fulfillment work will require a standard set of tools: tape measure, paint knife, wooden bars, a roll of tape, a few
packs of mounting foam, as well as sealant, moisture-resistant primer and, possibly, gypsum plaster.

The warming process takes place according to the following scheme:

2.Insulation with mineral wool

Kinds 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.
Semi-rigid type - compressed material - occupies a smaller volume, due to which it loses in thermal insulation properties.
Rigid type - thin material, but also ineffective for providing thermal insulation. It is used, as a rule, only in combination with other heaters.

Warming technology

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

3. Foam insulation

Types of foam. Properties

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

In addition to 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;

In comparison with polystyrene, polystyrene will gain large quantity glasses, since the material is not so fragile, more flexible and durable.

Insulation of slopes with foam plastic. Technology

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

When insulating window slopes in a relatively warm climatic region, two layers of material will be sufficient; in colder climatic conditions, polystyrene must be combined with other heaters, such as mineral wool.

4.Insulation with 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.

By purpose, sandwich panels are classified into:

roofing;
wall - used in finishing work

As a heater in these panels is used:

mineral wool;
expanded polystyrene;
fiberglass

The advantages of sandwich panels include:

good thermal and sound insulation;
human safety;
no response to impact chemical environment as well as mold and mildew
between the wall and the sandwich material, the gap is eliminated with the help of some kind of heat insulator, for example, mineral wool;
the outer side of the slopes is closed with an F-shaped profile to achieve an aesthetic effect

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

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

Thinking about how to veneer a shell house covered with ordinary rough cement plaster, I decided to choose panels with insulation. Facing facade panels with insulation are a convenient and interesting option, but finishing with this material has many nuances and subtleties.

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

Panel types - advantages and disadvantages

The very principle of the thermal panel device is several layers of finishes. Insulation layer, adhesive base and decorative coating with additional protective functions. Today there are four options for a sandwich, which are quite affordable.

Clinker tiles as a decorative layer - looks stylish and allows you to create any facade design. In this finish, the carrier layer is made of OSB, which gives the material extra rigidity.
For the base, it is better to choose a material that is additionally reinforced with pressed-in metal or plastic bushings. It's more reliable. In addition, it is quite possible to mount such a lining with your own hands.

Layer decorative plaster on polystyrene foam - there are many options. As a decor, you can choose the addition of marble chips or quartz. The advantage of such panels is the ability to create an ideal seamless finish surface.

In the photo - the rules for mounting metal panels

The metal coating is reliable and durable. The insulation is protected on both sides by aluminum or profiled sheet. You can choose any - under a tree or under a stone, but it will cost more.
The minus of metal is a heavy finish, the instruction does not recommend installation on old walls without additional strengthening and reinforcement.

Concrete coating with additional reinforcing additives and an interesting "torn" texture. Insulation - a layer of foam. The most budget option.

At mini-factories you can buy two times cheaper than in a store. This is the finish I chose. It can be painted both under a stone-sandstone, and under a marble or a 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 align all the flaws and irregularities.

Rules for cladding with any sandwich panels

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

Rule #1

It is important to calculate the loads on the foundation and walls, especially in older buildings with shallow strip foundation. Some insulated panels for the facade have a considerable weight ( concrete pavement or metallic). For clinker tiles, you will need to install the crate.

The architects advised in no case to choose a tree for the crate. Even treated with a deep penetration primer, it quickly begins to rot, besides, woodworm beetles love it very much. Only a metal crate, as 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 reinforcing reinforcement with a metal mesh and apply a layer of starting leveling plaster with reinforcing additives.

If there is no desire to pay for the calculations of architects for bearing capacity walls, it is better to stop at a lightweight version for exterior decoration - according to metal frame or light clinker tiles.

Rule #2

Be sure to look for a professional construction team, because fixing bad work will be problematic. That's exactly what happened to me. I hired craftsmen, they assured me that they worked with this material, but received not walls - but chessboard no frayed seams. I had to spend money on additional painting with decorative additives.

Let the masters show their work, do not be lazy, go and look at the object, talk with the owners. Now there are a lot of “craftsmen” who can do “everything”, but in the end they just spoil good material.

Rule #3

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

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

Metal plinth and decorative plaster;
A plinth made of textured pressed cement and wood-like siding - the plinth can then be designed to look like a bar or wild stone. Lots of decor options.
Clinker tiles are very “gentle”; it is good to use them as decorative inserts for panels covered with "torn" plaster.

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

Rule #4

Immediately decide 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 - the most reliable for the plinth and corners.

If there are strong temperature fluctuations or severe winters in the region, then it is worth choosing not an ordinary foam, but a bulk one. This material retains heat better and is not afraid of moisture.

Rule #5

When finishing the facade with sandwich panels, you cannot save on protective and disinfectant impregnations, because then you will have to change the entire lining.

Be sure to treat before installing the wall battens with an antiseptic and deep penetration strengthening primer. Northern walls even in two doses with a frequency of a day.
If the crate for finishing is made of wood, then we process the wood with a protective primer, and in addition you can also paint it.
It is important not to forget about the organization ventilation gaps- this applies to all materials that are attached to the crate, it does not matter if it is metal or wood.
If there is a close occurrence on the site ground water, then additional waterproofing of the basement is necessary. Suitable coating resin or ruberoid.

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 climate.

Summary

In the video presented in this article, it is described in detail about the installation of thermal panels on a metal crate.

I would be happy to discuss this interesting topic in the comments, and in the near future I promise a detailed article with photos of the “masterpiece” of my craftsmen. Maybe someone will advise interesting option painting.

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

Thermal panels - facade decorative elements

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

1 Features of facade thermal panels

It is worth mentioning right away that the presented metal and rustic facade panels trademark Rockwool represent the most rational and environmentally friendly solution to the thermal insulation issue.

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

Warming the facade of the house with Rockwool sandwich panels will give better results if they are fixed on an additional layer of foam.

By the way, unlike polystyrene, 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 fastening of the Rockwool sandwich panel to the outer surface of the facade (unlike foam plastic) can be carried out on such surfaces as:

Concrete;
Expanded clay concrete;
Classic brick on;
plastered facade;
Unplastered facade;
Block house wall;
aerated concrete;
Wood;
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, it may be the possibility of insulating old buildings with sandwich panels. Such products as rustic thermal panels can, if necessary, insulate the facade of a house with a broken geometric shape.

With the help of ordinary foam, it is almost impossible to perform such insulation work. In particularly difficult cases, in order to insulate the uneven facade of the house, instead of foam plastic, a sheathing is first carried out, which levels the work surface.

After that, 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 that was spent on conducting construction works and, consequently, their cost.
It is known that during construction work, a significant share of the costs is not only the purchase of material and wages, but also rent scaffolding, with which the facade work will be carried out.
The 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.
For this, by by and large need minimum set the most common tools. During installation, you can not do without:
Electric drills;
construction knife;
Hammer;
Screwdrivers as per .

Before you start installing the insulation, you need to make sure that the surface of the walls is even and has no significant flaws.
Facade panels can be fastened with glue, foam foam or dowels. It is known that the presented panels cost significantly less than the traditional one. brickwork, therefore, after carrying out simple calculations, you can find out the percentage of cost savings when conducting insulation in this way.
Insulation, presented in the form of thermal panels, completely relieves the owner of the mandatory need associated with the periodic repair of the facade and restoration of the outer surface of the walls.
However, if the work is performed without observing the requirements of the technology, then the insulating coating may undergo deformation.
The presented material has a long service life, which is 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 on the secondary housing market Vacation home. Decided to make it overhaul before settlement. When it came to the insulation of the facade, I bought and installed Rockwool thermal panels. Excellent insulation and, moreover, pleasing to the eye.

Sergey, 50 years old, Kramatorsk:
Lately old heating system failed to do its job well. I took up the exterior insulation of the facade. As a heater, I used a Rockwool sandwich panel. Now in all rooms optimum temperature. I recommend this heater to everyone.

Vladimir, 43 years old, Zhytomyr:
I am a small foreman construction team. We work mainly on private orders. When it comes to external insulation of the facade of houses, we use Rockwool thermal panels. These products have long been proven to be the best. Customers are always satisfied, excellent material, we have no complaints about its quality.

2.2 Clinker thermal panels
The presented variety of panels has clinker tiles as a decorative layer. Regarding the degree of resistance to aggressive impact environment, then the clinker outperforms some varieties of natural stone.
This material has a large number of colors and is made using shale clay. Such raw materials are currently mined in North-Western Europe.
This suggests that clinker is an absolutely environmentally friendly material that does not contain harmful chemical additives and impurities.
It is created during the implementation of the high-temperature firing method. Clinker panels show high performance mechanical strength, with a low value of water absorption.
Such material is distinguished by pronounced frost resistance and the ability to maintain its properties throughout its entire service life.
In addition to the fact that clinker panels show excellent thermal insulation and aesthetic performance, they demonstrate high sound insulation qualities.
In addition, the material acts as an additional waterproofing as. Such material is used not only as a heater and decorative element facade, but also for interior finishing work.
2.3 Thermal panels with porcelain tiles
Kermogranite is another type of insulation ceramic tiles. It is made from high quality raw materials, in the process of firing, exposure high temperatures and pressure.
The result is a very densely compressed material, which is practically unaffected by the harmful effects of the environment.
These indicators are significantly superior to natural natural stones. The presented thermal panels are especially quoted by those house owners who prefer to design a facade that has a detailed textured surface.
Thermal panels made of porcelain tiles are large in size, which easily allows them to imitate masonry.
As a rule, these products are used in houses, the appearance of which is oriented towards the Mediterranean or scandinavian styles. Despite the solid size of the plates, they weigh a little, so this allows you to install them with ease with your own hands.
2.4 Thermal panels with glazed tiles
This type of thermal panels is currently very popular. Their use is especially important in the process of finishing low-rise houses.
The popularity of this material was already noticed in the 60s of the last century. Glazed tiles are distinguished by their smooth surface and their heterogeneity. colors, which gives the facade of the house a resemblance to natural brickwork.
This material is characterized by good appearance, ease of installation work, high strength characteristics and a minimum number of shortcomings.
