Intumescent & Smoke Seal Replacement in County Londonderry: questions
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.
Does regulation 10 apply in County Londonderry?
No. County Londonderry is in Northern Ireland, where the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 apply.
