Siniat Shaftwall systems are fire rated non-load bearing walls used for lift shafts, service ducts, stairwells and fire isolated passageways. Shaft Wall systems are ideal when constructing a wall where access is only possible from one side. This side is referred to as the storey side.

Siniat Shaftwall can resist positive and negative air pressure surges up to 0.7 kPa, and can resist positive and negative sustained air pressures up to 0.5 kPa. Shaftwall systems are complimented by Siniat Shaftliner and other wall lining plasterboards.
