FIREDOOR RANGE>
• Introduction
Buildings are compartmented to delay the spread of fire from one area to another. The compartments are
usually linked by doors to allow for passage of ‘traffic’ around the building. Doorsets have two important
functions in a fire, when closed they form a barrier to prevent fire spreading and when open they provide
a means of escape.
• Performance Requirements
The performance of timber doors is judged by subjecting them to the standard test procedure specified in
BS 476 : Part 22. Tests are made on complete door assemblies, the door and frame with all the necessary
hardware. They are then fixed in a wall representing their use in practice.
• Intumescent Seals
All dedicated fire doors providing a half hour or greater performance will be fitted with intumescent
seals. These will be encased in a PVC sheath, of various colours. These seals are fitted in the door leaf
edges or the frame to seal the head and long edges of the assembly. Intumescent seals expand under
heating to seal the gaps between the door leaf and the frame and at the meeting stiles of pairs of doors.
• Smoke Control
To achieve competent smoke control, the intumescent seals used in the jambs and head of the fire doors
should be replaced with a corresponding combined intumescent/smoke seal.
