Abstract
A joining strip is provided by which sheet metal may be formed into a hollow tubular panel. The joining strip provides a seam between panel edges that acts as a thermal break between inner and outer faces of the panel. The joining strip may also carry a resilient tubular cushion which extends into the joint between the side ends of two panels that are connected by a hinge. This cushion contributes to providing an air seal within the joint between the two panels. Applications include roll-up garage doors and roll-away, articulated walls.
