Fire Door seals

Recommended Posts

Reason I`m just checking is I was going through some stuff on BWF site and watching fire door videos and came across this " 

Fire Door Seals

Do I need to fit seals on my fire door?

ALL fire doors MUST be fitted with the appropriate seals.

 I come across plenty of fire doors on offices within corridors with No strips whatsoever ?

Since 1987 and the introduction of BS 476 p 22 and 3,  FD30 fire doors have required intumescent strips and FD30s fire doors require strips and cold smoke seals. Prior to that they did not require strips/seals but they did use inch/25mm rebates and are considered acceptable today providing they are substantial, well fitting  in good order. However if they are in a poor condition they should be replaced with fire doors meeting the latest standard.

All timber based fire doors tested to BS 476 - 22 and EN 1634-1 'currently' have intumescent fire seals.  As an inspector I would always recommend existing / older timber-based fire doors should be fitted with seals. I do this on the basis that:

1) The building operator has a legal duty to take 'reasonable precautions' and keep fire doors in 'efficient' working order under the RR(FS)O.

2) The upgrading work is reasonably simple and cost effective.

3) Intumescent seals have proven evidence in tests in contributing to the fire separation performance of timber-based fire doors.

If a client then decided not to fit the seals to existing / older doors, then its a matter for them and their fire strategy and fire risk assessment. They should justify their decision.
