Deformable insulating panel for a goods-handling door, and a door including such a panel

摘要

A goods-handling door for separating different spaces in factories or warehouses includes a curtain that can be raised by being wound up or by being folded up concertina-like. The curtain is insulating both with respect to heat and with respect to noise, while being transparent so that one vehicle can be seen by another if they approach the door from opposite sides. The door includes two airtight flexible skins that lie parallel to each other and that sandwich spreaders between them. The spreaders are spaced apart and define intermediate spaces between the two skins. The spaces are filled with air, which provides the required insulation. Since the two skins are transparent, the door is transparent in the vicinity of the intermediate spaces.
