Shaftwall systems are nonload-bearing fire rated wall assemblies that provide critical, life safety, fire-resistant protection for elevator shafts, stairwells, vertical chases and mechanical enclosures. Shaftwalls in elevators and stairwells are one of the most important wall assemblies in a building. They provide the only means of evacuation from the building in an emergency. Vertical chases and mechanical enclosures keep vital communication, power, water, fresh air and exhaust systems intact when a fire occurs.
Shaftwall System consists of 1" shaft liner panels supported by 2-1/2", 4" or 6" CT-Studs and faced on one side with two layers of 1/2" fire code board.
Stairwell Systems are designed to enclose stairwells; this system is finished on both sides with a single layer of 1/2" fire code board.
