Compared to other parts of the building, heat leakage through the floor is lower, it is only 10-12%. However, the issue of reliable thermal insulation of the floor does not lose its relevance. After all, cold air spreads in the room from bottom to top. And even with complete sealing of the ceiling, roof, walls and windows, uninsulated floor will “dilute” cold air warm, and energy saving will not work. So, the losses on utility bills will not go anywhere. Therefore, and at the construction stage, and in the process of insulating the house already in use is very important to think about how to insulate the floor to give no chance for cold to get through the gaps in it.
Each floor – its own method of insulation
In private houses there are several varieties of flooring: wooden and concrete. And the features of insulation for each type are also different, have certain requirements and disadvantages that need to be eliminated, using the right insulator for the floor. For example, concrete flooring is very cold in itself, so insulation here should be as reliable as possible. In wooden floors, the main problem is cracks, and if there is not enough insulation under the boardwalk, unnecessary coolness will go into the house from there.
Choosing the insulation material
The market of thermal insulation materials for the floor is represented by various insulators in terms of composition, functionality, efficiency and durability. Another important aspect that distinguishes each floor insulation from others is the price (Ukraine is one of those countries where they have learned to approach the issue of heat economically).
Someone is too limited in funds or simply decides that it is not worth investing in insulation, and chooses the cheapest material. Someone, on the contrary, is sure that the most expensive will be the most effective. However, the cost of insulation is not only the insulation for the floor, the price of savings in how quickly the material will pay off, how effective will be protection from cold for many years.
It would seem that there is a lot to choose from: expanded clay, foam (ordinary and extruded), mineral and basalt wool, gypsum fiber, foamlex, aerated concrete, granulocrete, vermiculite, thermal insulation foam. Almost all of them have their disadvantages. For example, expanded clay, mineral wool and aerated concrete are too hygroscopic. Styrofoam and penoplex with improper use toxic and very “tasty” to rodents (mice can cleanly destroy the insulation under the floor!). Basalt wool and vermiculite too expensive, and this is without taking into account the cost of vapor barrier, which is mandatory in the installation of all of the above materials.
Really unique against the background of competitors is thermo-insulating eco-foam Aisinin – a universal insulator for the floor in a private house, which is characterized by a number of advantages:
- Durability;
- Environmental safety, the absence of toxic substances in the composition;
- Excellent soundproofing properties;
- Optimal vapor permeability, which allows you to achieve an optimal level of humidity in the house;
- Does not give a chance to mold and fungi;
- Not afraid of mice and rats;
- Does not rot;
- Does not burn.
Having perfect sealing properties, Aisinin foam reliably insulates the space under the floor, filling all possible voids and the smallest gaps. To work with eco-foam on top of the screed it is necessary to install lags, between which the insulation is sprayed in a layer of 10 cm. Please note that the foam is soft in texture, so you can not work with it without lags, which act as a frame. After spraying, you can lay the flooring chosen by the owners of the house.
If the ceilings in the house are low, and this fact does not allow to insulate the floor from inside the room, insulation with Aisinin foam can be carried out by treating the ceiling of the basement or the foundation with insulation.
