  • Energy saving building and method of making same
    Patent number: 4372089
    Abstract: An integral airtight layer 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 in two stories of the building can be united by a non-diffusion tight layer that encompasses an intermediate floor structure. The resulting building will be practically completely air tight.
