Patent
CA 2642384
The invention relates to a roof, ceiling or wall element (1) made of several successive superposed layers of wooden boards (2; 2a, 2b), where the wooden boards (2; 2a, 2b) of the successive superposed layers lie on top of each other with their broad surfaces (3) facing, and the wooden boards (2; 2a, 2b) of a layer are connected to the wooden boards (2; 2a, 2b) of at least the abutting layer by holding elements (4). A cost effective manufacture with small loss of material can be achieved by the fact that the wooden boards (2; 2a, 2b) on the mutually facing broad surfaces (3) are unplaned, and at least the small surfaces (8) of the wooden boards (2; 2a, 2b), which surfaces form a visible side of the roof, ceiling or wall element (1), are stepped at their edges with an upper and lower notch (9, 10).
