BUILDING PANEL FOR WALLS, ROOFS AND FLOORS, BUILDINGS MADE THEREFROM AND CONSTRUCTION TECHNIQUES USING SUCH PANELS

摘要

A building panel for walls, floors and roofs has an inner region defined by a pre- stressed concrete panel, metal or plastic studs or other construction articles. The region is at least partially filled with expanded concrete. In a preferred construction the expanded concrete includes up to about 80% of its holding capacity for air.
