Intumescent & Smoke Seal Replacement in Hanworth

We provide fire door seal replacements for buildings in Hanworth and the TW13 postcode district, from single doors to whole blocks and estates.

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.

Hanworth FAQs

Will new seals fix a door with big gaps?

No. Seals only work within the gap they were tested with. Gaps outside tolerance need the door adjusting first.

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.

Does regulation 10 apply to buildings in Hanworth?

Yes, if the building is a multi-occupied residential building with storeys over 11 metres. Hanworth is in England, so the quarterly communal door checks and annual flat entrance door checks apply to those buildings.
