Horizontal Shaftwall

A free-spanning membrane with no support from the soffit

Shaftwall can be specified for horizontal applications as a free-spanning membrane with no support from the soffit. The membrane can be constructed entirely from below and can achieve spans up to 5100mm and fire resistance up to 120 minutes. A typical application is for fire escape corridors. Supporting partitions should be of at least the same fire resistance period as the horizontal Shaftwall.

Please note that all British Gypsum Drylining systems are tested to the BS EN fire test standard. However we can continue to support your BS Standard Specifications project with remaining test evidence to BS 476. Please click here for more information.
