It’s no secret that the heat loss of a private house is much higher compared to apartments. The air heated by the heating system transfers its heat to the walls, ceiling, floors, which then partially release it into the environment. To save on heating — on bills or on fuel, it is advisable to insulate the building with special materials. There are quite a few on the market.
Professional builders say that there are no good or bad heaters, there are materials that are suitable or not suitable for each specific situation. We decided to help our readers in choosing the best products, and made a rating of the best wall insulation. We tried to cover each position of the review in as much detail as possible so that no one has any questions about the cases in which this material is used, how environmentally friendly it is, what composition it has. However, before starting to analyze heaters, I would like to give a number of useful tips regarding their correct choice.
How to choose the right insulation for the walls?
One of the fundamental factors is thermal conductivity — this indicator indicates the amount of heat that can seep through the thickness of the material. The lower the value, the better it will be possible to protect the building from freezing in the winter, respectively, the heating costs will be much lower. Another key point is the vapor permeability of the insulation. This implies the ability of the material to pass vapor particles through itself, without detaining them either in its structure or in the room itself. If the vapor permeability is low, then excess moisture will remain in the walls, which will ultimately lead to the appearance of mold, fungus and other unpleasant moments, which are not so easy to get rid of.
Over time, some materials can shrink, losing shape or volume simply under their own weight. To prevent this from happening, you will have to provide more frequent fixation points during the installation process. At the same time, there are materials on sale that can only be installed in a horizontal position, for example, during floor or ceiling insulation.
The mass and density of the insulation is also important, because the insulating qualities directly depend on these parameters. The density value usually ranges from 11 to 220 kg/m3. The higher the indicator, the better, however, with an increase in density, the mass of the material also increases — it is necessary that the supporting structures withstand the additional weight.
It is possible that during operation the insulation will be exposed to direct moisture. If there is no certainty that this will not happen, you need to purchase products with minimal hygroscopicity — it does not allow moisture to pass through itself, it does not deform under its influence. Depending on climatic conditions, a range of operating temperatures is also selected, which can range from -180 to +1000 degrees. Of course, you should also pay attention to the service life of the material — for some it is about 20 years, while for others it can reach 70 years. If you plan to insulate the room from the inside, then it is advisable to check that the products do not emit harmful or toxic substances into the environment that can adversely affect human health.
When we chose products to include in our ranking of the best wall insulation, we took into account all the factors considered. In addition, user reviews (including experienced professional builders) were taken into account, as well as value for money.

This material is based on very thin fibers, which are obtained by melting mineral raw materials at a very high temperature. The product is produced in the form of plates, which can be easily cut and sawn. The insulation does not conduct heat well through itself, but water vapor escapes through it almost instantly — you don’t have to worry about the formation of mold. It can also be used as thermal insulation. This characteristic is provided due to the special structure of the material, because the air gap between the fibers dampens not only sound, but also vibration vibrations. The products are non-combustible, so it is absolutely safe to use, which allows it to be used for finishing frame, wooden and block houses. The mass of plates is insignificant, the service life is at least 50 years. In the manufacturing process, insulation is treated with special water repellents that provide high water-repellent qualities.
It is undesirable to use this product for interior decoration, as it is produced with the addition of phenol-formaldehyde resins, which are used as a binder for fibers. Over time, they begin to emit harmful fumes into the environment, which can harm human health.
- In addition to high-quality thermal insulation, it has high soundproofing and water-repellent characteristics;
- Long service life — from 50 years and more;

7. PENOPLEX Comfort
It is used in professional and individual construction quite often. It has excellent technical parameters. In fact, the material is extruded polystyrene foam. High quality is provided largely due to the cellular structure of products. The size of the cells is in the range from 0.1 to 0.2 mm. They are located in the structure as evenly as possible, which positively affects the strength of the material itself and allows you to provide not only heat-insulating, but also sound-proofing characteristics. It is worth noting that the cells are not isolated, but connected to each other. Through such passages, water vapor escapes without lingering in the room. The sheets have edges made in the form of the letter «L», which allows not only to greatly facilitate the installation process, but also to reduce heat loss. As a rule, islands of cold appear at the joints of plates; this does not happen when working with such material.
This is one of the lightest materials in our review — its density is a maximum of 35 kg / m3.

It has another name Woodflex, it is an environmentally friendly insulating material that is produced on the basis of natural wood fibers. It can be used to fill elements of roofs, ceilings and walls in frame construction, suitable for thermal insulation of technical rooms and utilities. The products are quite elastic, so it is comfortable to finish even quite complex shapes. In use, the insulation is absolutely safe, you can not be afraid of the release of chemical compounds into the air of the room, and it is also not capable of causing an allergic reaction. Such plates are easy to install, since during operation a large amount of debris is not formed. Thermal insulation characteristics are very high due to the fact that in the manufacture of boards, wood retains all its basic natural qualities. Each fiber of the material has the ability to absorb and accumulate heat in itself. With this feature, a comfortable atmosphere will be created in the house, and daily temperature fluctuations will be minimized, which is most important on hot summer days.
Moisture can accumulate in the material, but at the same time its useful qualities will remain at the same level. Even if one cubic meter of insulation contains about 10 liters of water, it will still be able to maintain its original shape without a hint of deformation. The unique structure also provides sufficiently high soundproofing characteristics.

This insulation was launched on the market back in 2007 — it is manufactured by a fairly well-known domestic company «TechnoNIKOL», founded in 1992 and specializing in the production of finishing and building materials. When creating products, the latest scientific developments, as well as the most modern technologies, were used. Largely due to this, the insulation fully complies not only with Russian, but also with international standards. The basis here is mineral wool, which is an absolutely environmentally friendly material. With its help, you can significantly reduce heat loss, keeping the heat inside the room. This product interacts calmly with various chemicals found in masonry materials. It does not react with plaster and other mortars, gypsum, dry mixes.
Thermal conductivity is practically zero, however, it is necessary to lay the insulation in such a way that it does not come into contact with water. Otherwise, it begins to lose its useful characteristics. However, mineral wool easily tolerates mechanical and physical influences, it can be laid even in rooms with an aggressive environment. Despite the fact that the material is afraid of water, it easily passes water vapor through itself.
