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.
