Performance of fire-resisting timber doorsets
Fire-resisting doorsets are required to be able to contain a fully
developed fire, to facilitate escape of a building’s occupants and allow
fire-fighting, and to protect the structure from the effects of fire. The
doorset therefore must have resistance to fire, expressed in terms of
This Wood Information Sheet is intended as a guide to architects, quantity surveyors, building surveyors, building control officers, fire prevention officers and builders. It compares the various performance requirements for timber fire-resisting doorsets and makes recommendations on their specification.

This Wood Information Sheet was revised in October 2018.
This Wood Information Sheet gives guidance on assessing the suitability of existing doors for upgrading to give a 20 or 30 minutes' fire resistance comparable with that of purpose-made fire doors. Upgrading to 60 minutes' performance will rarely be possible.
Upgrading the fire resistance of existing doors is a...
Chiltern International Fire's Product Assessor Simon Bailey discusses the role of passive fire protection (PFP) products, in the context of Regulatory Reform (Fire Safety) Order, and emphasises the need for correct installation to ensure performance and life safety.

Even among experienced developers and engineers, the performance of mass timber buildings in fire is a sensitive and often misunderstood topic. Wojtek Serwatka summarises the current state of knowledge in the industry regarding self-extinction in mass timber structures and its relation to overall fire safety strategy.
