Abstract
Abstract A construction element of good thermal conductivity, designed for example as a facing for a heated or cooled floor or ceiling, comprises a board pressed from organic, mineralic and/or ceramic particles adhesively bonded together, with a metallic filler distributed therein. The filler may consist of powder, chips and/or filaments and may be supplemented by a metallic grid or foil embedded in or laminated to the board. One or more conduits for a heating or cooling fluid can pass through the board, preferably in a region of high filler density.
