The floor on the ground is laid between the foundation walls, most often on a compacted layer of sand or gravel. This type of flooring requires very good insulation, which main tasks are high compressive strength, proper and unchanging thermal insulation parameters, resistance to moisture, dimensional stability, insensitivity to cyclic freezing, defrosting and biological corrosion.

HOCH XPS extruded polystyrene insulation boards meet the above requirements, making it comfortable, healthy and economical to use objects with properly made insulation with our board.
