Shaft and duct encasement system

ShaftWall provides a lightweight, fire resistant structure to protect elements in confined spaces wherever access is limited to one side only. The system provides a protective structure which can be incorporated at an early stage of the construction without the need for scaffolding. The system can also be built horizontally to provide a fire rated membrane.


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.
