Floor insulation on the ground is also necessary as well as the insulation of the walls and roof. The correctly selected heat insulation thickness limits the alignment of the temperature between the warm floor and cold soil.
The insulation of the house from the soil is necessary as well as insulation of walls or roof. Thermal insulation in houses without basements, serves to limit the temperature difference between the floor and cold soil. The type of material used, as well as the sequence of laying layers may differ depending on each specific case.
If the thermal insulation layer is on a concrete plate, then it can be made of ordinary polystyrene plates or from hydrophobic, solid minvata of high density and strength. Despite whether we use mineral wool, or extruded polystyrene foam, the thickness of the thermal insulation layer should be at least 10 cm. In the case of mineral wool, it must be remembered that it is separated on both sides of other layers using waterproofing. Choosing polystyrene foam, it is better to take with fixed joints that allow you. Thanks to this, the risk of the formation of cold bridges will be much less.
If a layer of insulation is placed on a pushing layer, then the EPS 100 038 brand foam is used (it is characterized by low moisture absorption) 10 cm thick. It is especially recommended for insulating floors on soils of moisturizer. Another solution may be laying a layer of plates of extruded polystyrene foam XPS 200, 300 or 500 with a thickness of 8 cm.
