Patent
CA 2317326
There is proposed a lift door panel (1), which, apart from a good sound and vibration damping with a high degree of rigidity, is producible to be largely distortion- free, wherein a warping in the case of fire and under high heat effect is reduced or avoided. According to the invention this is achieved thereby that a front wall (2) and a back wall (3) are connected together by means of connecting means which are releasable under the action of heat, wherein in addition at least one heat-resistant connection is provided.
