Abstract
An overhead coiling door which includes a lintel seal interface assembly comprising a mounting bracket and a seal material sandwiched between a top and bottom row of brush bristles. The top row of bristles is shorter than the bottom row which provides relative rigidity to the flexible seal material and maintains greater cycle life. Further described are novel insulating material placement used to seal the building structure—door gaps. In one preferred design, a hinged guide cover has a first leg geometry to engage the structure and a second leg geometry to engage the curtain guide assembly to effectively seal gaps created by various amounts of curtain guide assembly setback.
