Shutter leaf for home, has two aprons separated by frame, and metallic films covering frame and serving as barrier to energy transmission due to radiation between aprons, where gap between aprons has multi-reflector type insulating material

摘要

The leaf has two aprons (1, 2) separated by a frame (3) that serves as a spacer between the aprons. A gap formed between the two aprons is used to maintain a multi-reflector type insulating material (6). The frame is covered with metallic films (4, 5) on all its surfaces in contact with the aprons. The films serve as a barrier to the transmission of energy due to radiation between aprons.
