Quick Overview

These systems are interior nonload-bearing gypsum panel partitions designed to construct elevator shafts, mechanical shafts, stairwells, air returns and horizontal membranes. SHEETROCK brand shaft wall systems have been comprehensively tested for 1- to 4-hour fire resistance ratings (UL Design No U415) only when all of the system components are used together. Substitutions of any of the components are not recommended. Metal framing members for the system consist of USG CH Stud, USG J-Runners, USG E-Studs and USG Jamb Strut. Each steel component is formed to produce a strong, highly efficient member.
