ClarkDietrich Shaftwall Systems

ClarkDietrich Building Systems provides fully tested and approved assemblies for shaftwall construction. What makes the ClarkDietrich system unique is that it has been tested with almost every gypsum board and shaft liner manufacturer in the country. Unlike competing systems, the ClarkDietrich CT Stud and J-Tabbed Track system provide maximum flexibility to choose from a variety of board manufacturers. Other systems are only tested with one type of gypsum board and shaftliner.

This unprecedented flexibility means quick availability of product at economical costs. It provides you with a choice and peace of mind knowing you’re using a tested and approved assembly.

 

 

Shaftwall System consists of 1" shaftliner 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.

 

 

 

 

Stairwall Systems are designed to enclose stairwalls, this system is finished on both sides with a single layer of 1/2" fire code board.

 

 

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.

Cavity shaftwalls are constructed utilizing one of two methods: masonry/CMU or light-gauge steel and gypsum. Gypsum drywall shaftwall construction has become the preferred and most widely used shaftwall assembly. These shaftwalls are lightweight, install faster, and provide lower inplace costs. They also significantly reduce structural framing and foundation costs. Masonry shaftwalls in high-rise buildings historically weigh between 20 and 45 lbs. per square foot compared to gypsum assemblies that weigh between 10 and 13 lbs. per square foot.

In addition to substantial weight reduction, gypsum shaftwall assemblies can be installed from the exterior of the shaft at each floor, eliminating the need for scaffolding. Shaftwall installation is easy, quick and clean. Light-gauge steel and gypsum assemblies provide fast, lightweight, low-cost and high-performance assemblies.
