A lightweight panel， a lightweight construction element， its manufacturing method， and a usage method

A lightweight construction element (1) comprises at least one lightweight panel (2) and a layer of insulating material (4) associated with the lightweight panel (2)， wherein the at least one lightweight panel (2) comprises boards (6) having， on at least one of the main surfaces (8) thereof， a group of parallel running grooves (9) and being arranged in at least one layer (5) and being connected to each other via adhesive bonds. The layer of insulating material (4) comprises wood chips (19)， which are removed from the starting boards during the manufacture of boards (6) with grooves (9) for the lightweight panel (2). These lightweight construction elements have good load properties and thermal insulation properties. The material used originates from one source and achieves a large overall volume after processing.
