When insulating a wooden house, there are always many questions that only a professional can answer with confidence. But if you don't want to spend extra money and choose the best solution yourself, then a selection of relevant tips from Novate.ru will help you with this in the best possible way. With them, the house, which has been letting the cold for a long time, will cease to bother with drafts and discomfort, but will become as comfortable and reliable as possible.

1. Preliminary preparation of wood for insulation

Usually, log cabins, which have already served for some time, require insulation. Therefore, their condition could worsen: they usually settle, which is natural, but defects and chips may appear that need to be found and strengthened. This is a very important point, because after insulation, there will be no open and easy access to wood for many years. If the logs are in good condition and ready for insulation, they should first be treated with an antiseptic and fire-fighting agent, and then dried thoroughly.

Helpful advice: If, when checking the wood, it was found that bugs had started up in it, then it is not necessary to insulate the house recommended, because there is no effective remedy for pest control, except for long-term exposure to very low temperatures.

2. Thermal insulation of a log house from the right side

It is recommended to insulate the log house exclusively from the outside. It is this approach that will provide the best result, as well as lead to an improved and longer service life of the load-bearing wall material and the insulation itself. If the insulation is carried out inside the building, then the evaporation of moisture, which is invariably present in a human dwelling, will lead to deterioration and deformation of the insulation and the logs themselves.

3. Correct determination of the thickness of the thermal insulation layer

For thermal insulation to work well, special attention must be paid to the choice of insulation, as well as its thickness. For example, 5 cm of insulation is enough if you need to ensure comfortable living in the house in the spring and autumn months. But for the winter, this thickness is not enough. If you plan to live in the house all year round, it is recommended to use two layers of insulation with this thickness. They can simply be stacked one on top of the other. When determining the thickness, it is important to take into account the territorial location of the house. After all, this recommendation is suitable for the central regions of Russia. In the south, you can limit yourself to one layer of insulation, and water for the northern regions will even need three layers.

4. The correct choice of thermal insulation material

Modern construction markets are downright replete with materials that can be used to insulate a wooden house. Therefore, choosing the right insulation takes a long time and with certain difficulties, especially when you want to buy the ideal one. A few basic tips will help you figure it out. First of all, we will define the three most common thermal insulation options. They can be made of glass wool, mineral wool, extruded or cellular polystyrene foam.

The latter has excellent thermal insulation properties that surpass the characteristics of other options. Expanded polystyrene practically does not absorb moisture and does not allow water vapor to pass through. However, when interacting with an open fire, it melts strongly and releases very dangerous gaseous chemicals. Therefore, when choosing this material, you need to show extreme care and additional types of protection, or use it exclusively where it will least of all interact with the tree: in the blind area, in the basement or foundation. If we compare mineral wool and glass wool, then their characteristics are similar to each other and are equally well suited for insulating a wooden house.

5. Choosing between flexible and rigid boards

On the modern market, you can find rigid and flexible thermal insulation mats. At first it may seem that they are the same, but in fact there is a difference. Rigid slabs retain their original shape for a long time, but flexible mats are especially good for insulating horizontal surfaces, for example, between floors or the space under the floor.
