Internal insulation is ideal for half-timbered or wooden facades, as the exterior of the house remains unchanged. In addition, it is suitable if external insulation is not possible. Perhaps you only have enough money for a phased approach – then internal insulation is a great solution.
Is it necessary?
Since wooden dacha and log cabins are often used only in the warm season, their hermetic construction provides relatively good thermal insulation due to the specific properties inherent to wood. This reduces the need to insulate the house itself. However, if you decide to live in the house all year round, then it is certainly worth it to insulate the wooden structure. In this case, it will not only be much more airtight, but also less cold in winter.
It is important to keep in mind that before starting any work on the insulation of a wooden house, it is necessary to take into account that the built house will settle. If this is not taken into account when choosing materials for warming and insulation, they may be damaged. Then you will have to redo all the work.
Different types of thermal insulation of a wooden house
Wooden houses are in great demand due to their numerous advantages. The natural atmosphere brings coziness and positive energy. But this does not mean that insulation of a wooden house is not necessary.
Let’s start with warming the floor. The best type of foundation for an insulated house is concrete. Then you need to assemble the wooden house, put on the roof and attach the roofing material to make sure that a sudden downpour does not interfere with your insulation work and does not wet the glass wool and floor boards. That is why floorboards should always be installed last, even if you do not want to insulate your wooden house.
The insulation is laid between the foundation beams, and the most suitable are rigid or semi-rigid plates made of mineral wool. Only this material creates insulation and keeps the house warm. Calculate the distance between the foundation beams, prepare panels of the required size. They need to be in contact with the ground to avoid moisture and ensure good air circulation. The thickness varies from 4 to 10 cm, depending on the size of the house and the manufacturer.
After warming the floor, you can deal with problems with the roof and its internal insulation. For an effective result, roofing tiles of the highest quality should be used to protect the roof from moisture and wind outside. The right roofing tiles combined with good insulation protect the home from bad weather and wind. Since 40% of the heat goes through the roof, it is very important that it is well insulated and covered.
You can insulate wooden walls with the help of mineral wool in the form of panels. Start with the vertical braces of the wall. If you choose such a material with a thickness of 5 cm, then you should use wooden bars of the same size. Consider the specifics of your climate.
The distance between the bars should be slightly smaller than the width of the insulation, so that the entire insulated area is filled, and the mineral wool is laid without fasteners. You can buy wooden boards, panels, plywood, OSB plates, etc. for internal wall cladding. Wooden houses with a wall thickness of more than 34 mm do not need insulation.
Advantages and disadvantages of internal insulation
Internal insulation is effective, significantly reduces heat loss. Acoustic comfort is excellent, and installation is faster and cheaper than outside. On the other hand, the living space is reduced and the location of the power grid must be revised. In the case of internal insulation, the decoration of the walls also needs to be redone.
