Abstract

The invention relates to low-flammability structural elements, particularly boards, and to a process for constructing them. The low-flammability structural elements are constructed utilizing combustible plastics waste material. They contain in addition non-combustible inorganic additives and a flame-proofing agent mixture. The components are held together by at least one hardened adhesive. Because of this build-up the structural elements display, despite the combustible components, low-flammability.
