How to make wall insulation for a private house from the outside efficiently, quickly and inexpensively? Can I do this kind of work with my own hands? It should be noted that important fact that insulation from the outside is not only an improvement in the microclimate and the creation of comfortable living conditions. Such events have purely economic reasons: the fact is that with high-quality wall insulation in the house outside, there is no need to use additional room heating systems (for example, electric heaters). This means that electricity bills will be noticeably smaller. The savings will be noticeable even if you heat your cottage with gas, because you do not have to use the maximum power of the boiler or other gas equipment you have. Another important plus of thoroughly warming the walls of the housing with your own hands is that at a low temperature, coupled with high humidity there is a high probability of developing fungi, mold: and if the house is warm and dry, this risk is minimized.
Thermal insulation of the walls of a private homeownership outside can be done both with the involvement of professionals and with their own hands. The choice of materials in the modern market is quite large, and each homeowner will be able to find an option that is optimal in cost. However, when choosing a insulation material, it is necessary to focus not only on cost, but also on other important points.
The first aspect of the choice is the material from which the walls of your country house are made. For each version of the insulation, individual installation methods are provided. And it may turn out that a certain type of insulation is suitable for your house, but it will be impossible to mount it yourself, or it will only be possible to insulate it with the condition of additional surface preparation and, accordingly, with the involvement of additional finances (and the total amount may turn out to be larger than you expected ) And in order to minimize both financial and temporary expenses, you need to choose insulation material very carefully.
It should be remembered that insulation for a private house outside will be most effective. The undoubted plus of thorough external insulation is that in this case the material will not reduce the living area of the premises, in addition, moisture in the rooms does not accumulate (there is no “sweating” effect).
External insulation is one of the most important points regarding the improvement of your home. Experts note that up to thirty percent of the heat can go through insufficiently insulated walls of the building. What materials should I prefer? There are many options, among which the most popular are:
- thermal insulation of the building with foam;
- mineral wool thermal insulation;
- use of “Penoplex” (extruded polystyrene foam) as insulation - only for basement and basement walls.
Exterior insulation of a residential building with foam
Polyfoam, without a doubt, is one of the most affordable, lightweight, and therefore very popular materials, with the help of which the walls are insulated for the house outside. In order to mount such a insulation material, you do not need any complicated additional devices: all the work can be done by yourself. However, one should not forget about such a lack of polystyrene as its instability to fire (this is a combustible building material).
Thermal insulation with foam can be carried out in the following way. First of all, surface preparation is performed: it is necessary that it be carefully aligned. Polyfoam is made in the form of plates, and if such a heater is applied to uneven surfaces, voids will inevitably appear and, accordingly, it will be colder in the rooms than might be expected. Secondly, with mechanical action in places where the foam plate comes in contact with an uneven wall, the material can simply burst. It is important to remember that isolated space is a possible place of accumulation of insects, moisture, etc. Therefore, it is very important, before starting wall insulation for a private house outside with the use of polystyrene, to perform a thorough primer. If there are, for example, significant traces of whitewashing on the walls, thermal insulation with foam insulation becomes less effective (the glue may not “seize”).
After the walls are thoroughly washed and primed from the outside, it is time to proceed to the next stage, namely, the installation of ebbs. They are aligned using the level on the horizon: this will allow in the future to make thermal insulation of the walls with foam with their own hands without additional cutting of the plates. Before laying the foam, you should put the “starting bar” - the base, which will prevent the slabs from sliding off the walls. In addition, it will become much easier to comply with the line during further installation. From how the bottom plate is exposed, it will depend on how smooth the entire row will turn out. When insulating the building from the outside with foam plastic, the plates are mounted on their own using special glue. In the event that the walls in the house allow, you can additionally fix the material with nails in a few days.

If your house was built from timber, you should additionally cover up all the cracks: with mounting foam, mineral wool or other materials suitable for this purpose. It is important to eliminate drafts: without this, insulation from the outside of a residential building will not be so effective.
External insulation for the house with mineral wool
Thermal insulation outside a residential building can also be carried out using another popular material - mineral wool. If you have heard, for example, that the walls are insulated with "glass wool" or "stone wool" - then this is one and the same material. It is based on fiberglass. As a rule, for external thermal insulation, special slabs of mineral wool are used, and they sheathe the facade.
For the installation of this type of plates, special fittings are used. To warm the attic and the roof of the building, it is recommended to use Linrok cotton. Its advantage is good flexibility, which means that in order to perform thermal insulation for the house outside, you do not have to conduct thorough preliminary preparation of the surfaces.
The undoubted advantages of stone wool are:
- low thermal conductivity combined with high sound insulation;
- relatively low price;
- stone wool does not support combustion;
- it is not susceptible to damage by rodents, as well as the occurrence of mold and fungus;
- vapor permeable material, the building "breathes";
- stone wool is easy to install with your own hands: you can choose the best type of insulation - in rolls or mats;
- The material is eco-friendly and safe.
External wall insulation for home ownership using stone wool is carried out in several stages. With the help of a plaster mixture, boards are glued to the wall surface. Next, mineral wool is covered with another layer of the mixture, then a fiberglass alkali-resistant fiberglass mesh is installed, a primer is applied and, finally, finish (painting, decorative plaster, etc.).

Thermal insulation “Penopleks”: we insulate the building with our own hands outside
As well as in the cases of mineral wool or polystyrene foam, one can do the external thermal insulation of the building’s walls with the help of “Penoplex”. Today, this material is very popular for independent thermal insulation of residential buildings.
Important! It is possible to insulate with “Penoplex” only the basement and basement walls. The fact is that this material does not allow water vapor passing through itself, tending from the living quarters to the outside, which can lead to the formation of fungus and mold.
Important advantages of Penoplex for thermal insulation of a building:
- the material is light, warm enough and durable;
- extruded polystyrene foam is immune to moisture;
- the material is fireproof, practically does not burn when exposed to high temperature;
- It is easy and convenient to mount it with thermal insulation of the building yourself.
The thickness of “Penoplex” for thermal insulation of a residential building, according to modern standards, should be at least 5 centimeters. This material is laid in several stages:
- alignment of surfaces, elimination of cracks, primer;
- installation of "Penoplex" on a special glue, after 2-3 days - additional fixing of the material with dowels;
- gluing reinforced mesh;
- prefinishing;
- finishing of the facade using facade plaster.
In order for the insulation of a residential building to be of high quality, do not spare money on insulation material. If the thermal insulation with foam, “Penoplex” or stone wool was carried out in compliance with all the rules, you will be able to provide the most comfortable atmosphere in residential premises and, at the same time, reduce heating costs.
