Shaft wall system. They are specifically engineered to prevent the spread of If ShaftWall is built on the same line as the beamwork framing the shaft, problems may arise in trying to seal the wall up to the steelwork. 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. USG Corporation remains a leading manufacturer of ceiling, wall, backerboard, underlyament, gypsum, roofing, sheathing, and industrial products. The Cavity Shaft Wall System includes components that provide the strength to withstand lateral loads and fire protection necessary for walls that enclose elevator shafts, stairwells and other vertical shafts. Shaftwalls are interior fire-rated wall assemblies that provide life safety protection for elevators, stairwells, chases and mechanical enclosures. It is recommended that, wherever possible, the wall should be located to one side of the beams, and fixed from structural floor to structural soffit. The system includes gypsum liner panels, gypsum panels and cement board, interior finishing products and framing components. For heights up to 4400mm. Best of all, gypsum shaftwall systems are more economical than masonry shaft construction. National Gypsum produces Shaftliner board with green moisture-resistant paper or purple moisture/mold/ mildew resistant paper on both sides with a beveled edge configuration allowing for simple installation into the Shaftwall System framing. fcg jzl sfkm rqmqf gffgv opewpc hcsgu zggv fyam hef
