Fire-resisting timber doorsets

Fire-resisting doorsets, as distinct from single ‘fire door’ leaves, are precisely designed and engineered component sets required to perform three main functions: Protect escape routes from the effects of fire (including smoke) so occupants can leave safely (includes lofts and conversions), protect the contents and/or structure of the building by limiting the fire spread (an insurance requirement), and permit fire fighting.

Key Information

Each component plays a critical role in the doorset’s fire resistance. Unauthorised changes in specification may impair the performance of the whole doorset. Any changes from the tested specification should only be made with the approval of an appropriate expert authority, such as a UKAS-accredited testing laboratory.

Case studies

The latest addition to the University of Kent campus is the Colyer-Fergusson Building, containing a first class concert hall in which timber is used to provide the ideal warmth and acoustic qualities for music performance.

The Wooden Annex is a single-storey, fully timber extension to a 1950s end-of-terrace house in South London. The addition of the annex accompanied a complete refurbishment of the existing house, creating increased and improved open living space for the homeowners.
