Fire Door Gap Adjustment in County Londonderry: questions
Why do gaps open up over time?
Hinges wear and drop, frames shrink or move, leaves warp, and doors are sometimes planed after flooring changes. Each needs a different repair.
How big can the gap under a fire door be?
It depends on the door's evidence. Doors without smoke control often allow a larger threshold gap, sometimes up to around 8 to 10 mm, while smoke control doors usually need 3 mm or less or a tested drop seal.
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.
