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 contents and/or the structure from the effects of fire. The doorset therefore must have resistance to fire, expressed in terms of time.

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 April 2017 and changes were made to reflect updates in harmonised product standards and CE marking.
