Abstract: A stud for use in building structures is provided with a thermal break. The thermal break is formed by rows of slits with adjacent portions of the sheet material displaced relative to one another. This enables the stud to be formed by a simple rolling operation, without requiring a separate stamping operation to remove parts of the material. The stud can be formed integrally with an exterior panel, or can extend between interior and exterior panel portions of a combination panel.

Abstract: A building panel is formed from a single sheet of material, and comprises an inner panel portion, a web portion, and an outer panel portion. The web portion extends between the inner and outer panel portions. In use, the panels are arranged with adjacent inner and outer panel portions overlying one another. Consequently, an outer wall surface can be formed from the outer panel portions, while an inner wall surface is formed from the inner panel portions. To insulate the wall, insulation can be provided between the inner and outer panel portions.

Abstract: A pressure relief wall assembly has a liner panel and first and second exterior panels. A first portion or end of the liner panel is secured to one part of the frame. A second portion or end of the liner panel is releasably fastened to another part of the frame, by a plurality of first elements, which elements fail when an excess pressure is applied to either side of the wall assembly. A first end or portion of the first exterior panel is secured to the one part of the frame, and a second end portion of the first exterior panel is secured to the liner panel, for example, at a location midway between the two parts of the frame. The second exterior panel has a first portion secured to the other part of the frame. A second, end portion of the second exterior panel is releasably fastened to the liner panel or to the first exterior panel by a plurality of second elements, which fail when excess pressure is applied to the assembly. In response to excess pressure, the first and second elements fail.
