Abstract: Roofing or wall panels are installed and connected together edge-to-edge with the aid of a special mounting clip and a seam strip. The mounting clip is attached to the seam strip and to the supporting structure of the roof, and during installation the seam strip becomes locked to an edge of each of two panels. The mounting clip is a two-piece assembly having a connecting portion adapted to cooperate with a complementary portion of the seam strip, the two-piece construction facilitating connection of the clip to the seam strip at any point along the strip and thereafter preventing transverse withdrawal. Locking of the seam strip to the edges of the roof panels is effected by deforming the seam strip into gripping engagement with the panel edges.

Abstract: An exterior wall or roof assembly for a building comprises parallel metal framing members supported in spaced relationship to an inner supporting structure by metal clips which are secured to the inner supporting structure and which during assembly are deformed to clamp the edges of the framing members between opposed surfaces of the clips, the opposed surfaces of the clips being thermally insulated from the framing members so that there is no metal heat flow path between the framing members and the inner supporting structure.
