Abstract (en)
[origin: WO9004080A1] A rational means for sound-insulating existing doors consists in mounting on the door leaf (2) a metal frame (1) that can be provided on its outer side with hollow sealing strips (4). These hollow sealing strips made of rubber are pressed against the door frame (3) when the door is closed, ensuring the required insulation.
