Method of building an energy saving building, and an energy saving building

摘要

An integral airtight layer (12; 57, 50) in the floor, the walls and the roof surrounds the entire useful space of a house or other building. The tightness of the layer is tested before the flooring and inner wall linings are mounted. The airtight layer is made of a diffusion tight material so that it serves as a vapor barrier. The vapor barriers (57) in two stories of the building can be united by a non-diffusion tight layer (50) that encompasses an intermediate floor structure (51). The resulting building will be practically completely air tight.
