The CH Studs are specially designed for Shaftwall Systems, whereby access is only via one side, such as those commonly found in lift shafts, stairways and garbage shoots. The CH Studs are designed to provide friction-fit contact for 25 mm Gypsemna’s Core Board as shaftliner. CH Studs normally space at every 600 mm to suit the width of the Gypsemna’s Core Board panel.
