Abstract
Formed sheet metal elongate studs and furring channels with two separate sections bonded together, each section having means for attachment to a wall base or a wall facing material. The sections are bonded together with a heat-sensitive material, preferably a hot-melt adhesive, which melts and separates the sections in a fire, and also tends to reduce thermal conductivity through the stud under conditions that do not melt the adhesive.
