Abstract:
Certain aspects of the present disclosure provide movable barrier, including: a frame having a first side and a second side parallel to the first side; a first exterior panel connected to the first side of the frame and including: a first non-planar profile; and a first plurality of perforations; a second exterior panel connected to the second side of the frame and including: a second non-planar profile; and a second plurality of perforations; a cavity defined between the first exterior panel and the second exterior panel; and a liner disposed within the cavity and configured to: deform when an air pressure differential acting on a first side of the liner exceeds a pressure differential threshold and allow increased airflow through the movable barrier.
