Extruded polystyrene foam for floor insulation: advantages and installation methods
Very often, when warming the house, many forget about such an important part as the floor. But it is through the floor that part of the heat simply goes into “nowhere”. This is especially true of the part that is located in close proximity to the soil. The soil can freeze by 1-1.2 meters, this means that a significant part of the heat may leave. When choosing a material for floor insulation, it is worth giving preference to extruded polystyrene foam, since the material for insulation is in contact not only directly with the soil, but also with moisture, which accumulates from the outer part of the house. And in order not to insulate the floor, you can buy modular flooring, unlike the rest, this coating does not require insulation.
Extruded polystyrene foam not only sufficiently strong material, it practically does not absorb condensate and moisture, which plays a really large role while maintaining heat. The foundation wall must be insulated up to the lower level of freezing of the soil. If your house does not have a deep foundation, and the floor is located directly on the ground, you need to pay special attention to quality insulation. To choose the right material, it is necessary to take into account the specifics and nature of the flooring in your house. In this case, your choice can be stopped on mineral wool.
