Insulation of a brick house outside with penoplex under siding - how to insulate walls with penoplex and sheathing with siding video - how to insulate a house under siding. The main points of insulating the facade of the house outside with foam plastic with your own hands under siding Insulation of penoplex

Penoplex Is a synthetic insulation produced in the form of slabs. It has a porous structure due to which it has excellent thermal insulation characteristics.

It can be used for insulation practically any surfaces and does not require special skills to install the slabs on the walls of the house.

Standard width sheet is 60 cm, and the length is 120 or 240 cm.The thickness of the sheet can be from 2 to 10 cm.

Penoplex benefits for insulation of brick walls from the outside:

Good thermal insulation properties... The thermal conductivity of the material is 0.030 W / (m * C) according to GOST 7076-99. This is one of the lowest values of the indicator among all heaters.
Low vapor permeability... The vapor permeability coefficient of the material is 0.007-0.008 mg / (m * hour * Pa). A 2 cm thick slab can hold vapors in the same way as a layer of roofing material.
Virtually zero water absorption according to GOST 15588-86. Moisture is not absorbed into the internal structure of the material, so even baths and saunas can be insulated with it.
High strength... Penoplex can withstand significant loads, strong compression and significant breaking forces.
Good sound insulation.
Fire resistance... The material in production is impregnated with special substances that prevent fire.
Ease of processing and ease of installation... Penoplex is well cut with a painting knife, and you can work with it in any weather.
Penoplex has light weight(thanks to the cellular structure with air bubbles).
Lifetime - up to 50 years... During this time, foam boards retain their original shape and all their properties.

Disadvantages of Penoplex:

Decomposed by direct sunlight and some solvents.
Unnatural origin.
Strong smokiness (even after fading).
Quite a high price.

The technology of insulation of a brick house with penoplex outside

Thermal insulation method "ventilated facade"

This method is used when insulating a house penoplex under siding.

Siding is a modern material for exterior wall decoration. He perfectly protects the facade buildings, easily tolerates the effects of snow, wind and rain, is easy to clean and retains its original appearance for many years.

Penoplex insulation of a brick house under siding passes in several stages:

The walls are cleaned of dirt and old coatings, then a layer of primer and antiseptic is applied to them.
After they dry, the crate is mounted on the walls.
Penoplex slabs are cut and placed between the battens of the sheathing, fixing with special glue.
After the glue dries, the plates are fixed with dowels with an umbrella hat.
A crate is mounted for siding, on which the panels are installed.

Important: Installation of siding panels can be done at temperatures from -10 degrees.

More detailed insulation technologies slab materials are described in the article "", since the technologies are identical.

Materials and tools

For work on insulating a brick house with penoplex, you will need the following instruments:

Master OK;
rule;
putty knife;

siding panels.

In conclusion, we can say that the insulation of the outer walls of a brick house with penoplex is one of the the most demanded methods thermal insulation of buildings. The material has gained its popularity due to its high quality and excellent thermal insulation characteristics.

With a competent approach and the availability of the necessary tools and materials, insulation of external walls you can do it yourself or contact experienced professionals.

Master class on insulating a brick house with penoplex outside under siding, look at the video:

Today, the relevance of using such material as siding in modern construction is quite understandable: siding wall cladding perfectly hides all existing defects, makes the appearance of the house more attractive, and at the same time differs in a relatively low price compared to its counterparts. The main advantage of such wall cladding is that it provides for the installation of heat-insulating materials.

In this article, we will talk about the advantages that insulation provides for walls outside the house for siding, about installation technology, price, we will find out reviews and opinions of people and much more, which will help determine the choice of the best insulation for walls outside the house or cottage.

Types of heaters

Insulation materials for walls based on mineral wool are sold in roll and slab form with different densities, which affects their characteristics and, of course, the price of the material.

Glass wool. Such insulation for walls outside the house for siding is made on the basis of fiberglass. They are realized in slab and roll form. This type of insulation for walls outside the house is widely in demand in private housing construction as it has a low price, which makes the material available to all consumers.

Styrofoam. This type of insulation for walls outside the house is also very popular, although less than mineral wool and glass wool, but this does not mean that such insulation for the walls of the house is worse, it just loses to them in some respects, but in some ways it is vice versa is superior.

Extruded expanded polystyrene. Such insulation for the walls of the house has good performance, which makes it widely in demand in modern construction. Insulation of a brick house from the outside with expanded polystyrene provides a high rate of heat saving.

It should be noted that insulation for walls outside the house, which would fully meet all the requirements, is not so easy to choose, because each of them is effective with its own set of characteristics, both good and bad.

And in order to choose the right insulation for walls for siding, which would be more suitable in your case, be sure to take into account the climatic conditions, the type of walls that will need to be insulated, and so on. Many make a big mistake when, when choosing insulation for walls for siding, they pay attention only to the price, while they do not even think about what degree of efficiency will be provided to a wooden house with such wall insulation.

That is why, in order to know for sure which insulation is best for your home, carefully read the reviews of people who had to deal with the insulation of the facade of a wooden house.

Below is a video clip, after watching which you will have an idea of how the external insulation of a house under siding with your own hands is carried out:

Styrofoam. This is a very good, and most importantly, low-cost insulation for siding for a brick house, which has high thermal insulation characteristics. Among the advantages of such a heater for siding, one should especially highlight its excellent moisture resistance, low thermal conductivity, low price and ease of installation not only outside, but also inside, for example, a log house, its installation can be carried out on vertical and horizontal wall surfaces.

Now about the disadvantages. Polyfoam is a kind of insulation for siding that can disrupt natural air exchange inside a wooden house, since it has low vapor permeability. The walls of a wooden house when facing with foam plastic will not be able to "breathe", because of this, moisture begins to collect between the walls and the insulation under the siding, which then appears in the form of condensation.

Also, the disadvantages of such wall insulation outside a log house can be attributed to its fragility - the operating time of the foam is twelve to fifteen years. In addition, the foam burns, while releasing hazardous substances.

As for the sound insulation of such insulation of a log house outside under the siding, it cannot boast of this either, since it actually amplifies the sound even more, acting as a resonator. Therefore, before choosing such insulation for the facade of a wooden house, weigh the pros and cons well, read the discussions about the material and only then decide the issue with its choice.

In the photo above, you can see how the facade of a private house is insulated with foam.

Mineral wool. Such insulation for siding, as well as its varieties, which include basalt wool and glass wool, can be called the best heat insulator, which is successfully used for external insulation of a house under siding, and it does not matter at all whether it will be a wooden or brick house, and in that and in another case, it will provide high thermal insulation.

In terms of thermal insulation characteristics, mineral wool is not much inferior to foam. The main advantage of mineral wool is that it does not burn, which makes the insulation of a wooden house outside with mineral wool for siding completely safe. In addition, all the modifications of mineral wool that exist today are vapor-permeable and, based on people's discussions, are considered the best sound insulator for the walls of a log house, and this speaks volumes. Below in the photo you can familiarize yourself with the wall insulation scheme with mineral wool.

In the photo you can see the insulation of the walls of a wooden house with mineral wool.

In the photo you can see a diagram of the device of the "insulation cake" on the walls of a wooden house.

Despite the huge number of advantages of insulating a wooden house outside with mineral wool, the material has a big drawback, which is its hygroscopicity, it is seventy percent. Therefore, when insulating a wooden house outside with mineral wool, you will need to apply a waterproofing material. However, there is also a big problem here, that is, if an ordinary film is used for waterproofing, then in this case the vapor permeability of the mineral wool will come to naught.

In order to provide better protection of the insulation against moisture penetration into the interior, it is necessary to use diffusion membranes for the waterproofing device, in which the vapor permeability index will be from four hundred to one thousand g / m2 per day or more.

The use of such waterproofing by fifteen to twenty-five percent will increase the estimate for wall insulation outside for the siding of a wooden house or cottage. Also, of the minuses, it should be noted that mineral wool when insulating a house can cause allergies as it is very "dusty", so it is better to use it only for insulating walls outside a brick house, and not inside.

Extruded styrofoam. The material is successfully used to insulate a wooden house. The main advantage of expanded polystyrene is its ease of installation and durability, it can last for thirty years, and even more. Unlike foam, such insulation outside the house for wall siding has higher strength characteristics.

Air cells in the structure of extruded polystyrene foam improve its thermal insulation properties. The one and only big minus that is inherent in this insulation is a high degree of fire hazard, and it is not so much the fire itself that is terrible, but thick suffocating smoke that causes poisoning. That is why it is better not to use it to insulate a house or cottage whose walls are built of wood.

Extruded polystyrene foam compresses very poorly, this makes it resistant to breakage, and if it happens that, for example, a log house begins to shrink, then the expanded polystyrene installed on the walls will not crack and crumble. In addition, the insulation has good resistance to moisture and temperature extremes. From the numerous reviews of people, one can understand one thing, that such insulation of walls from the outside with foam plastic for siding for a house is one of the best options.

In the photo you can see the insulation with extruded polystyrene foam.

Photo: installation of extruded polystyrene foam on a brick wall.

Looking at the table, you can see that all these materials for insulating a house for siding have a very similar thermal conductivity. The highest characteristics are inherent in basalt wool, which makes this material the best option for insulating the outside of the house with mineral wool for siding, and it can be used to insulate brick, lumber and wooden houses for siding.

House insulation technology under siding

Currently, there are several technologies that allow you to install insulation outside the house with mineral wool under siding with your own hands with little time. The first option for insulating a brick house with mineral wool can be considered really budgetary, this is when simple insulation materials in rolls are used for insulation, their installation is as follows: the insulation is glued to the surface of the wall and then fixed on it using the made crate. Judging by the reviews of many people, this technology is currently simple and affordable.

The next installation option is do-it-yourself interframe insulation of a log house under siding. Here, insulating plates of increased rigidity are used as insulation, the installation of which is carried out in the cells of the previously made lathing for siding and are fixed to the wall surface with screws or glue. The mineral wool installed in the cells of the crate will lie flat and adhere well to the brick wall.

The photo shows a diagram of the device for interframe two-layer wall insulation.

There is another technology for insulating a log house - installation on a cross frame. It must be said that it is precisely this technology of insulating a log house, according to experts, is the best, only the price of work and materials in this case will be rather big.

The fact is that with this technology, the installation of insulation takes place in several stages: first, a crate for siding is fixed to the surface, it is filled with insulation, then another crate is installed on it and also filled with insulation. Installation of the first lathing for siding with insulation is carried out vertically, and the second horizontally, so you can completely get rid of cold bridges.

Although such wall insulation outside for siding is expensive, it will always be warm in your wooden house. This technology is also well suited for the insulation of brick and concrete walls. Below you can watch a detailed video on how the installation of insulation under siding is carried out using a simple technology:

Many who decided to insulate their wooden house very often ask themselves the question: what kind of insulation for the facade is better to choose for siding and why? It is impossible to unequivocally answer this question, since all heaters for siding differ in their pros and cons.

For example, polystyrene and all its varieties are distinguished by good resistance to the effects of moisture on them, because they have a small degree of vapor permeability, but because of this, the effect of stuffiness will always be present in a wooden house. But as for the mineral wool, when it gets wet, it loses about fifty percent of its inherent thermal insulation properties, therefore, during insulation with mineral wool outside the house, it will be necessary to equip additional protection for the insulation with the help of waterproofing materials.

Despite the weaknesses, mineral wool today, based on numerous reviews, is considered the best material for insulating walls outside for the siding of a wooden house, cottage. It must be said that such a facade insulation for siding in combination with a waterproof barrier will be able to provide a log house with excellent thermal insulation and sound insulation performance.

In addition, mineral wool is one hundred percent environmentally friendly, can last for many years, while the cost of mineral wool is low, which makes such insulation for the facade available to all buyers. As for the opinion of experts about mineral wool, they all unanimously assert that mineral wool insulation outside the house for siding is the most reasonable solution that can solve the issue of arranging the best facade insulation at home with your own hands.

Do-it-yourself insulation of a house outside with mineral wool for siding: step-by-step instructions

To make it clear to you how the installation of insulation is carried out, below we will present instructions for installing insulation for siding. So, if the insulation outside the house for siding will be carried out with the help of mineral wool, then in this case it is better to purchase hard plates and attach them to the surface of the walls with a wet method. The step-by-step instructions below will help you make facade insulation with mineral wool yourself.

First of all, we need to fix a metal cornice at the bottom of the wall surface. This is necessary so that the insulation, in our case it is mineral wool, lays down evenly, in addition to this, this way you will provide the insulation outside the house for siding with the best protection against rodents, which, judging by the discussion of people, for some reason prefer mineral wool more than other materials.

The wall on which the mineral wool insulation will be carried out must be well primed.
To make a reliable attachment to the wall of the mineral wool, we need polymer-cement glue, it is not difficult to make it, you just need to pour water into the dry mixture and mix it well until you get a homogeneous mass. The finished glue must be applied to the back of the facade insulation.
It will be necessary to fasten the mineral wool starting from the bottom and moving to the top in such a way that a dressing of the seams is formed (as with brickwork). During the installation of mineral wool, it is necessary to ensure that the plates adhere well to each other. The mineral wool slabs glued to the wall surface should be additionally secured with plastic dowels, which have large caps, although this should not be done immediately, but wait one day. When fixing the facade insulation under the siding, you need to ensure that the plates do not disperse to the sides.

That's all, mineral wool insulation of a wooden house is ready. And in order for you to better understand how such work is done, read people's reviews and watch the video instruction:

Insulation of the walls of a brick house with expanded polystyrene

If you decide to insulate the walls with expanded polystyrene, then such work is best done in the summer, when the weather is hot outside the window. By the way, mineral wool insulation is also best done in dry weather. The surface of the wall that we will insulate with expanded polystyrene must be dry, that is, moisture must not get on it for three to four days before the installation of the insulation.

First, you need to well clean the surface of the wall from the dirt on it, if there are irregularities there, you also need to get rid of them.
As soon as the walls are prepared, they will need to be leveled; a primer is used for this.
We glue the insulation sheets to the wall surface.
Next, you need to cover the insulated area with a primer, and only then you can proceed to installing siding on the walls of a wooden house.

The photo shows how to insulate brick walls with mineral wool.

Such wall insulation for siding will be very effective and will provide you with a comfortable existence even in the most severe frosts. The main thing is to competently carry out work on the walls insulation with expanded polystyrene from all sides of the wooden house, otherwise the wall insulation for siding will not be of high quality, therefore, there will be drafts and cold in the wooden house.

To prevent this from happening and you would not have to throw money down the drain, you need to approach the work of insulating walls with expanded polystyrene responsibly and strictly adhere to the video instructions:

and then the result will not disappoint you.

Installation of insulation under siding: step-by-step instructions

In order for the insulation with mineral wool or any other heat insulator to be done correctly, you need to follow the instructions and make the right calculations.

To install wall insulation for siding, it is required to take insulation, the thickness of which must be at least four to five centimeters.
With the help of glue, the siding insulation is fixed to the crate, which is installed on the surface of the outer wall of a wooden house.
Installation of insulation for siding starts from bottom to top.
As soon as the walls of the wooden house are fully lined with material, you can proceed with the installation of siding.

Lathing for siding with insulation

The cladding of the facade of a wooden house must be started with the installation of the lathing. At the moment, the best and most inexpensive way is the use of bars or slats, such a crate will allow not only conveniently installing siding, but also installing insulation under the siding. The step of the wooden lathing should be between thirty-five and forty-five centimeters. All wooden elements of the lathing for the facade must be treated with a special antiseptic.

In the photo you can see the device of the wooden lathing of the facade of a log house, as you can see here everything is very simple.

The need for lathing is due not only to the fact that it is necessary to align the walls, but also to arrange a place for laying insulation.

There is another type of lathing for facade insulation, it is made of metal. Such a crate for the facade will last for more than a dozen years. In order to be able to set the indent you need from the wall surface, you will need to use special suspensions.

In the photo you can see the lathing device for the facade of a brick house.

The photo shows a diagram of the installation of lathing and siding.

To better understand what a crate for a house for siding is, watch the video presented for you:

You can also read the discussions of people who made the crate for siding with their own hands.

The price of work on the insulation of the facade for siding

It is not difficult to do any of the existing methods of insulating walls outside a wooden house for siding yourself, but if for some reason you cannot do this, then entrust such work to specialists. The cost of insulating a wooden house for siding will directly depend on how much work needs to be done. In the table below you can see the approximate price of insulation for siding the facade of a wooden house.

Siding is not only a way to give a building a beautiful appearance, but also a great way to protect thermal insulation installed on the facade of a building. After all, insulation outside allows you to save the usable area of a private house, i.e. decorating a house with siding allows you to kill two birds with one stone - decorate the cottage and insulate it.

But, since siding (vinyl, metal) insulation itself is very conditional, insulation under siding is a fairly common phenomenon.

This sandwich can reduce heat loss by up to 70%. The main condition is a reasonable choice of insulation and its correct installation.

There are several types of heaters on the market, each of which requires compliance with its own installation rules.

We offer to consider the most popular types of thermal insulation materials, as well as the features of their installation.

What insulation is better for siding

In order for thermal insulation to serve for a long time and productively, the following factors must be taken into account:

climatic conditions and thermal conductivity index... Different heat insulators have different thermal conductivity. The lower this indicator, the more suitable the insulation is for cold climates;

incombustibility... From the point of view of fire safety, the insulation should not burn, should not support and promote the spread of the flame. And also he should not spread harmful substances under the influence of open fire;

moisture resistance... Wet insulation loses its thermal insulation properties;

durability... This refers to the preservation of the characteristics and geometric dimensions of the material during the entire service life;

environmental Safety... Despite the fact that the insulation is carried out outside the building, the desire to protect your home from the harmful effects of hazardous compounds is inherent in every sane person;

ease of installation... This parameter is especially important for those who are going to insulate themselves on their own, without the involvement of expensive professionals.

Insulation methods for siding

There are at least two types of thermal insulation devices for cladding siding panels.

Option 1 - "light" insulation

A method based on the use of roll insulation, for example, foamed polyethylene foam (roll, sheet).

The thickness of polyethylene foam is only 2-10 mm, which does not allow us to speak of it as a full-fledged insulation. But he is quite capable of protecting the house from drafts.

Option 2 - full insulation

A method of insulation for siding focused on the use of dense types of insulation.

1. Solid types of insulation for siding

These types include aerated concrete and aerated concrete, as well as polystyrene and expanded polystyrene.

It should be noted that these heaters are often used under plaster. However, those owners who, after reading what kind of insulation mice do not eat, prefer solid insulation. Since this is the only thermal insulation material that is not of interest to rodents.

Installation of insulation under siding

Warming with solid wall insulation is performed as follows.

The surface of the house, prepared for cladding with siding, is completely laid with blocks of foam concrete or aerated concrete. Since such a wall is flat, you can mount the siding directly on aerated concrete. But, most often, a crate is arranged (from a metal profile or a wooden bar), between which insulation and siding are attached.

However, it should be noted that foam concrete and aerated concrete as insulation are not widespread among consumers.

And extruded polystyrene and expanded polystyrene, on the contrary, are quite a popular material on the market.

The properties of polystyrene and expanded polystyrene as insulation are presented in the table.

Benefits of Styrofoam and Styrofoam:

low cost;
no need to use film;
high speed of installation.

Flaws:

flammability.

Good to know. Expanded polystyrene has the lowest thermal conductivity in comparison with all heat-insulating materials. This is due to the technology of its production. Expanded polystyrene is made by extrusion, which gives it a high density and the absence of air chambers.

Thermal insulation with polystyrene and expanded polystyrene under siding - instructions

Both materials are similar in shape and structure, so the principle of the device will be identical.

Installation of slabs is carried out in several steps.

Cutting the sheet to the required size. If the crate was mounted taking into account the parameters of the sheets, then only those sheets that need it need to be cut off.

Fastening a sheet of polystyrene (or expanded polystyrene). Sheets are installed between the beams or the sheathing profile. For greater reliability, the sheets must be "planted" on an adhesive solution.

It is recommended to fix each sheet with a special dowel with an umbrella.

Good to know. The gaps that have formed between the sheets, as well as between the sheets and elements of the crate, can be blown out with foam. This will prevent heat loss.

The mounted polystyrene and expanded polystyrene are shown in the photo.

Sometimes, these heaters also play the role of a supporting material for outbuildings that are not intended for permanent residence (summer cottages, sheds, etc.). Of course, such frame "walls" are subsequently sheathed with siding.

2. Soft types of insulation for siding

These types include glass wool and mineral (basalt) wool.

On the market, cotton wool is found in rolls or sheets, which does not affect its characteristics.

Insulation of the facade with mineral wool for siding is perhaps the most common method of thermal insulation. We will dwell on the choice and correct fastening in more detail.

Advantages of insulation with cotton wool:

multidirectional fibers, which allows cotton wool to retain its geometric parameters longer;
fire resistance;
ease of installation;
long service life.

Flaws:

formaldehyde acts as a binder for cotton wool fibers, which makes this material not environmentally friendly;
low level of hygroscopicity. Vata is capable of absorbing water.

Good to know. Improperly mounted cotton wool gets wet and loses its properties.

SNiP regulate the thickness of insulation for houses intended for permanent residence based on the regulatory requirement for resistance to heat transfer (Rtr) and its actual indicator. Using the table below, you can make an informed choice of basalt wool. The thermal conductivity coefficient of the heat-insulating material is taken equal to 0.036 W / (m * C °).

Mineral wool insulation for siding - instructions

cut the insulation into pieces of the desired length.

Advice. Before mounting the cotton wool, it is advisable to unwind it and leave it for an hour and a half. So its structure will align and the insulation will be ready for installation.

install pieces of cotton wool between the vertical beams of the sheathing;

fix the cotton wool with dowels.

a waterproofing film, wind barrier or superdiffusion membrane should be pulled over the cotton wool;

The purpose of the film is to ensure the safety of the heat-insulating material from the appearance of condensation and to preserve its heat-insulating properties.

Advice. The higher the vapor permeability of the film, the better. The superdiffusion windproof membrane Tyvek (Tyvik) has the highest vapor permeability.

It is a revolutionary material in the construction industry. Since the structure of the film allows you to keep moisture outside and at the same time release steam from the room. In addition, its structure is able to withstand wind loads. This is not an advertisement, but an opinion based on practical use and feedback.

Good to know. Vapor permeability of Tyvek is 1300g / m2 in 24 hours.

fix the film with a construction stapler. It is important to maintain an overlap of 100 mm;

further, it is desirable to make a counter lattice on top of the film. It is a wooden slats stuffed over the frame. Its purpose is to create ventilation between thermal insulation and siding panels.

In finished form, the insulation siding will look like this:

3. Blown types of heaters

A novelty on the building materials market is inflatable insulation (inflatable, spraying, spraying, pouring).

Ecowool and penoizol are used as blown insulation.

Advantages:

ease of installation (for the master);
high density;
no requirements for the presence of films or other additional waterproofing materials;
good thermal conductivity.

Flaws:

high price;
availability of special equipment for spraying insulation and work experience.

In terms of its heat and sound parameters, ecowool is similar to cotton wool.

Advice. Ecowool can be applied by hand. To do this, you need to fluff it up, put it in place and tamp it.

Thermal insulation of the facade using the wet method using special equipment consists in blowing blown cotton or foam insulation between the battens of the battens. It is important to inflate them more or less evenly, and the remains are removed using a metal or wooden T-shaped structure.

Conclusion

In this article, we looked at approaches to insulating a house for siding. I would like to believe that now you not only know which insulation is better for siding, but you will also be confident that you can install it yourself.

A house built from any material is capable of losing heat through walls, roofs and other building elements. Even if you do not always save on heating, it turns out to achieve the optimal temperature regime.

Therefore, you should take care of insulating the house outside with penoplex with your own hands under siding. One material is able to reliably keep heat in the room, and the second one will transform the house from the outside.

The material is popular both in private construction and on an industrial scale. All thanks to a number of advantages that Penoplex has:

The minimum indicators of heat conductivity. Thanks to this, it retains all the warm air inside the house.
Moisture repellent properties. The material does not absorb moisture at all, which means that it is not afraid of mold or fungus, which like to settle in a warm and humid environment.
More durable than Styrofoam.
Long service life.
It can be used for insulating buildings made of gas and foam concrete, as well as silicate bricks.
The presence of soundproofing properties.
Ease of handling and installation. There is no need to acquire specific tools if the developer will do all the work with his own hands.

Apparently, Penoplex really deserves popularity, since there are a lot of positive characteristics.

Manufacturing technology

Insulation is a close relative of polystyrene, since it is also made from polystyrene balls. But there are some differences in the technological process that allow you to create a material with improved characteristics.

bunker - polystyrene, fire retardants (reduce the flammability of the material) and other additives are loaded. Everything is mixed here;
Extruder - in this machine, the components are fused and mixed several more times. In addition, another component is attached - a blowing agent, which creates a large number of cells filled with air;
forming sheets using rollers or plates.

Thanks to this production, penoplex is obtained, suitable for insulating almost all buildings and important communications.

Design features

As mentioned above, it consists of a large number of cells filled with air. About 98% of the foam volume is air, and only 2% is polystyrene itself. At the same time, it is clearly seen on the cut that the structure is homogeneous, and the bubbles are evenly distributed throughout the entire layer of insulation.

It is known from physics lessons that air does not conduct heat well, that is, it heats up and cools down for a long time. Thanks to this, the material has thermal insulation properties.

Scope, is it possible to do the work yourself, do it yourself

Since penoplex has a lot of positive characteristics
as a heat-insulating material, it is used for insulation:

Facades in private construction.
Plinths and foundations.
Loggias and balconies.
External walls of industrial facilities and public buildings.
Various pipelines.
Required tools

When insulating a house outside with penoplex with your own hands under siding, you do not have to buy any special tools. The usual set that any responsible owner has is quite enough. The following tools are required:

pencil or stamp for marking;
tape measure;
building level and plumb line to determine the horizontal and vertical;
hammer or screwdriver;
puncher for making holes for brackets;
a clerical knife or an ordinary sharpened knife, a hacksaw for cutting foam sheets.

What exactly needs to be purchased at a hardware store is fasteners, that is, umbrella dowels.

Preparatory work

To carry out any work, it is necessary to carefully prepare the bases. You should not skip this stage, even if the house is completely new, and even more so for old buildings. The presence of fungal deposits under the penoplex will contribute to the rapid destruction of the main structure. After all, mold and mildew thrive in a warm and humid environment.

If cracks remain on the wall, they will become cold bridges. This means that there will be no effective insulation. In this case, the owner will lay down all responsibility on the team that performed the work or on the material. Different reasons require a special approach at the preparatory stage, therefore we will consider two options:

wooden structure;
brick house.

Wooden base

Wood is rightfully considered an environmentally friendly material. In such a house you feel light and comfortable. But at the same time, the material is short-lived. Quickly enough absorbs moisture from the environment and at the same time loses its attractiveness, and even thermal insulation properties. Therefore, when preparing a wooden base for penoplex, they are attentive to:

Presence of mold, mildew or insects on the substrate. Everything is carefully cleaned and treated with a special antiseptic compound, as well as a moisture-repellent agent.
Differences on the wall. If there are strongly protruding places, it is better to cut them down or remove them in another way.
Cracks. If the house is built of rounded logs, then it is necessary to caulk the inter-crown space with natural material and only after that proceed to sheathing with penoplex.
If there are rotten parts, they are replaced and reinforced.
The new home is given time to shrink naturally.

In addition, do not forget to remove all hanging structures that can create inconvenience in the process of finishing the house. And all metal parts that cannot be removed are coated with a special compound that protects against corrosion.

Brick base

A brick base also requires careful preparation. The main stages practically do not differ from a wooden house:

freeing walls from curtain structures;
sealing cracks and depressions - cement mortar is used for this;
cleaning the base from dust, stains and mildew. Here you need to choose the right means suitable for processing bricks;
a new structure takes time to shrink.

If you do everything yourself, but correctly, then the premises will become warm and reliable, and the siding finish will cover both the insulation and the main structures from the negative effects of the environment.

Frame fabrication and vapor barrier

In order to attach the penoplex to the wall, there is no need to install an additional frame. The material is securely fixed with glue and mechanical fasteners to the base. But to fix the siding on the penoplex, a crate is needed. It can be made from:

Wooden beams.
Metal profile.

But before starting the insulation process, the walls should be covered with waterproofing. To do this, use a vapor barrier membrane or bitumen mastic. If it is a film, then they begin to lay it from the bottom of the wall, so that the next layer covers the previous one by 10-15 cm.

The joints are glued with tape, the membrane is fixed with a construction stapler. The entire surface is treated with mastic, without missing a single detail. It is imperative to completely dry the layer.

Wooden frame

Wood lathing is capable of withstanding vinyl panels, but metal siding will require something sturdier. Wooden parts are coated with a protective compound that will help extend the service life.

A wooden frame is installed already on top of the foam, you just need to wait until the adhesive composition, on which the heat insulator was attached, has completely dried. To fix the battens, front dowels are chosen, the length of which is equal to the thickness of the insulation multiplied by 2.

Such a frame will not only serve as a supporting structure for siding, but also create a ventilation gap. For foam insulation, it is simply necessary to leave such a gap for the natural removal of excess steam.

Metal crate

If a metal profile is chosen for the installation of the siding, then the brackets will have to be fixed even before the insulation is attached. Therefore, they adhere to the following plan:

laying waterproofing;
markings for brackets;
installation of brackets;
fixing the penoplex;
fastening guides.

In order for the insulation to be conveniently placed in those places where the brackets are, holes are made in the penoplex and put on the parts. Be sure to glue the heat-insulating material, and then additionally fix it with dowels.

After the outer walls are sheathed with insulation, the guides are fixed to fix the siding. This will create a ventilation gap.

Instructions for thermal insulation of the house outside

The technology of wall decoration with this insulation is quite simple. A beginner can do the job on his own. The only thing that has to be done carefully is to study the theoretical foundations of the process. If you follow the instructions, then there should be no problems.

Thermal insulation of walls with mineral wool

To attach mineral wool under the siding to the base, you will need to make an additional crate, which will be an additional support for the insulation. The scheme of actions is approximately as follows:

Laying waterproofing.
Installation of a frame for mineral wool.
Installation of mineral wool mats.
Laying another layer of waterproofing.
Fixing insulation and membranes with dowels with wide caps. For a secure fit, there are 5 mechanical fasteners per mat.
Installation of a frame for siding.

In this case, the entire structure will be as reliable as possible and insulation over time.
will not settle.

Heat insulator installation

As for the penoplex, there is no need to mount an additional frame for insulation here. This significantly reduces the time required to complete the work. In order for the insulation to be fixed securely, they adhere to the following plan:

a starting profile is installed above the foundation or plinth;
finishing starts from the bottom corner of the house;
an adhesive solution is applied to a sheet of penoplex around the perimeter, and several blunders are made in the center;
the lower edge of the element is placed in the starting profile and pressed tightly against the base;
the next sheet is covered with glue and tightly applied to the first sheet;
this is how the first row is finished;
in the next row, the sheets are shifted to the side, half the length. This method of fastening will help to avoid the coincidence of the seams, which means that the structure will be stronger;
sheathe the entire wall.

When the glue dries up, they begin to mechanically fix the foam. Holes are made using a puncher. Dowels are installed in them, after which the core is screwed in.

Fastening the guide elements

Under the siding, you need to set the guides correctly. If the panels are installed horizontally, the profiles are aligned vertically. The elements are spaced evenly, and the distance between them matches the distance between the holes in the perforated edge.

For panels that are installed vertically, a horizontal crate is suitable. In this case, too, all parts are evenly spaced. Do not secure the guides too close to each other. The optimal distance will be 40-50 cm. During fixing, be sure to control how evenly both the profiles and the siding panels are attached.

To insulate a house of penoplexes, it is completely unnecessary to select special weather conditions. It is enough that it does not rain or snow. The drying time of the adhesive solution will depend on the ambient temperature, but the quality of adhesion is not affected.

Before buying material and doing everything with your own hands, still consult with professionals. Maybe for a specific building it is better to choose another insulation or finishing material. In addition, a master who knows his business will help you accurately calculate the amount of materials and the thickness of the insulation.

Heat loss through the walls of a building can range from 30 to 80%, depending on the material of the walls. When choosing a heater, you need to take this into account, and choose a heater with the lowest degree of thermal conductivity... The specific type of material will depend on two factors: climatic conditions and the material of the building walls.

Materials for insulation of external walls for siding

Types of heaters:

Mineral wool insulation. They are made from metallurgical waste, silicates and other rocks. The thermal conductivity of the material is 0.042 W / m * K. Minvata has good fire-fighting properties. The main disadvantage is high coefficient of water absorption(about 70%).
EPPS(extruded polystyrene foam). Low thermal conductivity (0.03 W / m * K); water absorption does not exceed 2%; ease of installation. These advantages and the high density of the material (up to 40 kg / m3) provide it high thermal insulation properties. A significant drawback is the high degree of flammability.
Expanded polystyrene suitable for insulation of foundations and rooms with high humidity.
Styrofoam. It has a low level of thermal conductivity (0.035 W / m * K) and water absorption. The material contains many gas bubbles. The buyer can choose slabs of different thicknesses and densities. The disadvantage of styrofoam is that rodents love it.
Polyurethane foam. Obtained by mixing two substances - polyol and isocyanate. Low thermal conductivity, good sound insulation, high density, low water absorption. Resistant to mold, decay, rodents and insects do not start in it. Its disadvantages: destroyed by UV; when attaching siding the integrity of the layer is violated, and this reduces the effectiveness of the material.

The first two types of insulation have better sound insulating properties than polystyrene and expanded polystyrene, but at the slightest wet lose their thermal insulation properties Therefore, it is better to mount mineral wool with special membranes. Polyfoam and EPSP during installation may require additional sound insulation.

When choosing between rolled and slab materials, the following should be taken into account: rolled mineral wool serves more efficiently on horizontal surfaces, does not fit well at the joints, and so that the dew point is not in the room, the material must be laid in two layers. Plate insulation does not have such disadvantages, therefore more often used for wall insulation.

The environmental friendliness of the material plays an important role. Here, basalt insulation, polystyrene and polyurethane foam wins.

What kind of insulation to choose for the facade?

The owners of timber, log and log houses appreciate unique properties of wood, its environmental friendliness, low thermal conductivity. When insulating a house with its siding, it is important not to lose these advantages and not increase the disadvantages (fire hazard, high degree of water absorption, insects).

From this point of view, PPU is perfect for a wooden house. The material has good vapor barrier, is applied in a thin layer and does not weigh down the walls of the building. Fire safety, resistance to temperature extremes. The microclimate inside the wooden house will be preserved.

For wooden structures, mineral wool and fiberglass are also popular because of their fire-fighting properties.

Brick houses

Extruded polystyrene foam and basalt insulation are recommended for brick houses due to ease of installation and soundproofing properties.

Foamed polyethylene with the addition of fire retardants, extinguishing additives is used to insulate brick houses. Lack of the need to involve installers.

Despite the indicated disadvantages of polystyrene, it is actively used in the insulation of brick houses for siding. The reason is simple - ease of installation, relative cheapness of material and environmental safety. For families with children and allergy sufferers, this is a great option.

Houses made of aerated concrete and foam blocks

When choosing a heater for aerated concrete, it must be borne in mind that blocks of this material are distinguished by high vapor permeability. The wrong choice of thermal insulation can only worsen the indoor climate and shorten the life of the home.

The vapor-proof material will disrupt gas exchange between the room and the environment.

Condensation will collect at the border of the wall-insulation and will moisten the wall. Aerated concrete will be covered with mold and will start to rot.

Mineral wool insulation, like aerated concrete, has a high vapor permeability. Such a "duet" will have a positive effect on the microclimate at home. Due to the ease of installation and relatively low cost, mineral wool is often used to insulate houses from aerated concrete.

Polyurethane foam is also gaining in popularity. For houses made of aerated concrete, this is the ideal option. The most effective way to use the spraying method- this way you avoid cold seams.

Styrofoam, expanded polystyrene have poor vapor permeability, therefore, it is necessary to use them to insulate houses from gas blocks in extreme cases.

Frame houses

For external insulation of frame houses, mineral wool is most often used (see photo). Experience shows that the price-quality ratio is the most acceptable. But the material is needed isolate from moisture and dew points. This is done using a vapor barrier and membrane film.

Despite the negative attitude of specialists towards polystyrene, homeowners very often use this material for insulation. Cheapness and the absence of the need for additional moisture, noise, and vapor barrier play a decisive role.

Insulation of frame polyurethane foam by spraying also has many advantages. For frame houses, as well as for brick, foam concrete, this is an excellent option.

How much does it cost to sheathe a house with siding?

The final cost of insulation and siding of the facade depends on the price of materials and the cost of work. The cheapest insulation is foam. The price of siding depends on the manufacturer, the material from which it is made.

We will calculate the approximate cost based on average prices and panel sizes. Imagine that you want to sheathe a house with a facade area of 63 sq. M. You will need the following materials:

vinyl siding (3.85 x 0.231 m). 150 rubles × 80 pcs. = 12 thousand rubles;
waterproofing film (50 m.) - from 1600 rubles;
mineral wool at a price of 1500 rubles / cubic meter m in total, 9.45 cubic meters will be needed. m. 1500 × 9.45 = 15 120 rubles;
consumables (screws, slats, corners, etc.) - up to 15 thousand rubles;

The total cost of finishing will be RUB 43 720

When using the services of professionals, expect an average of RUB 1,500 per sq. m. Of course, depending on the qualifications of the workers, the price in the price list can vary significantly.

Do-it-yourself cladding and insulation of the facade using the example of mineral wool

Consider the procedure for insulating walls with mineral wool and cladding with metal siding:

Preparing the walls. We clean the facade from cement smudges, metal pins, communications, drainpipes and other things. We seal up cracks and chips with cement mortar and apply an antifungal coating to those areas where there is mold.
Installation of horizontal battens. The step of the horizontal lathing is determined by the width of the thermal insulation boards with a deduction of 2 cm (to ensure the necessary density when laying the insulation). Use bars with a cross section of 50 × 50 mm or 40 × 50 mm.
Laying insulation boards. We put plates between the beams. They will hold due to the reduced pitch of the sheathing. One edge folds over the bar, and the other folds in for a good fit.
Waterproofing layer. We fasten the diffuse membrane with waterproofing properties to the bars with construction clips.
Vertical lathing. This part of the lathing is fastened to the level. If there are irregularities, special linings can be made. Planks 25 mm thick are used here.

Siding installation:

When inserting the siding into a special lock, do it smoothly, without pulling, until it clicks. If there was no click, then the element is not fixed.
After fixing the profiles, fix the panels in the direction from the middle to the edges. Vinyl siding can be fastened with nails, screws, but always with galvanized hardware to avoid rusty streaks.
The fasteners must enter the panels strictly vertically, with a 1 mm gap between the surface and the head.
When the temperature changes, the panels will "walk", so there should be 5 - 8 mm gaps at the joints.

Durability and insulation service efficiency and cladding completely depends on the selected material and competently carried out installation. Coziness and warmth to your home!
