Floor element for building construction, has prefabricated concrete slab with contact surface covered with thermal insulation material layer to form thermal interruption between vertical side of slab and non insulated part of construction

摘要

The floor element (1) has prefabricated concrete slab (2) with vertical transversal sides and vertical longitudinal sides. The sides have a contact surface that is in contact with a non insulated part of a building construction (8). The contact surface of the slab is covered partly with a thermal insulation material layer (3) made of polystyrene foam to form thermal interruption between a vertical side of the slab and non insulated part of the construction. An independent claim is also included for a method for fabricating a floor element.
