Insulated slab for use in floor of building, has reinforced concrete layer and insulation layer including closed cavity, where wall of closed cavity includes emission reducing layer with specific emission coefficient

摘要

The slab (1) has a reinforced concrete layer (3) and an insulation layer (2) including a closed cavity (6), where a wall (7) of the closed cavity includes an emission reducing layer with an emission coefficient less than 0.5. The emission reducing layer is applied by coating, laminating or painting the wall of the closed cavity.
