Stevenage FAQs

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.

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.

Do you work in occupied buildings in Stevenage?

Yes. Inspections and repairs in Stevenage can be carried out in occupied flats, schools, care homes and workplaces, with doors kept closable at all times.

Which fire safety law applies in Stevenage?

Stevenage is in England, so the Regulatory Reform (Fire Safety) Order 2005 applies, together with the Fire Safety (England) Regulations 2022 for multi-occupied residential buildings.
