BlazeFrame interior steel framing is a fire-stopping, head-of-wall system for lightweight steel-framed buildings. With an affixed fire-stop material on steel profiles, the product provides a fire rating and a smoke and sound seal of dynamic and static perimeter joints. The design is said to offer protection and support for as much as 3 inches of movement, while eliminating requirements for caulks, sprays, drywall rips, and contour drywall cuts throughout joint assemblies. When exposed to heat in excess of 325 F, the fire-stop material expands as much as 35 times its size.
