KNAUF SHAFTWALL DOUBLE LAYER

SHAFTWALL

SYSTEM IS DESIGNED FOR USE WITHIN ELEVATOR SHAFTS AND STAIRWELL AREAS THAT PROVE TO BE A VITAL LIFE SAFETY LINK IN MULTI-STORY BUILDINGS. THESE WALLS ACT AS THE MAIN FIRE PROTECTION BARRIER AGAINST FIRE, THEY HELP TO PREVENT FIRE ENTERING THE LIFT SHAFT AND SPREADING RAPIDLY FROM FLOOR TO FLOOR. SHAFT WALL SYSTEMS PROVIDE ONE OR TWO HOUR FIRE RESISTANCE RATINGS IN  NON-LOAD BEARING CONFIGURATIONS.THE SYSTEM IS DESIGNED TO WITHSTAND THE CONTINUOUS SURGE OF AIR PRESSURE CAUSED BY FAST MOVING ELEVATORS. THESE  SYSTEMS ARE CONSTRUCTED USING THE KNAUF CT AND J-TRACK CHANNELS THAT  SUPPORT THE 1” (25.4MM) TYPE X CORE BOARD AND BOTH THE ½” (12.7MM) AN 5/8” (15.9MM) TYPE X GYPSUM BOARDS.

ELIMINATE THE NEED TO BUILD EXTENSIVE SCAFFOLDING THE 610 MM

WIDE TYPE X CORE BOARD MAKES INSTALLATION FAST & EASY AS IT FRICTION FITS WITHIN THE CT STUD AND AUTOMATICALLY PROVIDES A 24” (610 MM)  O.C SPACING READY FOR THE CLADDING OF THE TYPE X GYPSUM BOARD ON THE OUTER FACE. SHAFT WALLS CAN BE ERECTED FROM ONE SIDE, ELIMINATING THE NEED TO BUILD EXTENSIVE SCAFFOLDING.
