In short: intumescent seals are strips set into the edge of a fire door or its frame that expand when heated to close the gap around the door. Smoke seals, usually brush or fin seals, block cold smoke before the intumescent reacts. Both are part of the door's tested performance.

Intumescent & Smoke Seal Replacement in Belfast: questions

Does regulation 10 apply in Belfast?

No. Belfast is in Northern Ireland, where the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 apply.

What is the difference between an intumescent strip and a smoke seal?

An intumescent strip expands in heat to seal the gap during a fire. A smoke seal, often a brush or blade, blocks cold smoke at lower temperatures. Smoke control doors, marked with an S such as FD30S, need both.

Can I just stick new seals over the old ones?

No. Seals should be fitted into the groove after the old seal is removed, in the size and type the door was tested with.

Can you price remedial work in Belfast from another company's report?

Yes. Send the report and we will price each line for your building in Belfast, or revisit specific doors if the report lacks detail.
