Abstract
An insulation and weatherstripping arrangement and associated method for a rolling door includes an insulation supporting member to support a block of expanded polystyrene or similar insulation inside a vertically extending cavity disposed between a guide track and a wall. Most advantageously, metallic parts disposed on the inside of the door are thermally isolated from metallic parts disposed on the outside of the door. Additionally, inner and outer weatherstrips are used for further minimizing heat loss.
Claims8
A door comprising a plurality of slats connected for relative pivoting between adjacent slats, said slats mounted for movement along a vertical guide track, said guide track mounted on a mounting flange projecting out from an inside surface of a wall and having a vertically extending cavity between said inside surface of said wall and said guide track and bounded by said mounting flange;
- and insulation disposed in said vertically extending cavity, and insulation being in contact only with stationary surfaces, and further comprising an insulation supporting member bounding said vertically extending cavity opposite said mounting flange, said insulation supporting member mounted to an opening surface of said wall, said opening surface defining an opening, and extending between said wall and said guide track, said insulation supporting member supporting said insulation disposed within said vertically extending cavity, and wherein said insulation supporting member is L-shaped in horizontal cross-section with two legs, one leg parallel and attached to said opening surface of said wall, the other leg parallel and attached to a surface of said guide track, said surface of said guide track being parallel to said inside surface of said wall.
