Abstract (en)
[origin: WO2022013228A1] The invention relates to a multi-layer wall element for building up drywalls (2) comprising an insulating ply (3) with two flat sides (5a; 5b) of heat or sound insulating material which have a large surface area relative to front sides (6), wherein a support layer (5) is placed with an inner flat side (5a; 5b) of the support layer (5) against each flat side (5a; 5b) of the insulating ply (3), wherein a cover layer (7) is placed against each outer flat side (5a; 5b) of the support layer (5), and wherein the support layer (5) is, along at least two directions (R1, R2) which are oriented parallel to a plane (E) of the support layer (5) and perpendicular to confining edges (8) of the support layer, offset relative to the cover layer (7) by a respective offset amount (V1/V1'; V2/V2,), wherein the support layer (5) forms a tongue (10) at least along a first confining edge (8) and along at least one opposite second confining edge (8) a groove (11) together with the insulating ply (3) and the cover layer (7).
