Fire Door Gap Adjustment in Lisburn

From the BT27 district outwards, we cover Lisburn and neighbouring towns such as Belfast and Castlereagh for fire door gap adjustments.

Fire door gap adjustment is the work needed to bring the gaps between a fire door leaf and its frame, and under the door, back within the tolerance in the door's evidence, typically 2 to 4 mm around the edges. We use the same method for buildings in Lisburn.

Lisburn FAQs

What gap is allowed around a fire door?

Most guidance and manufacturers' evidence expect gaps of about 2 to 4 mm at the head and edges, with 3 mm as a practical target. The door's own certification or test evidence takes precedence if it states a different figure.

Can you fix a big gap with a thicker intumescent strip?

Not as a general rule. Seals are tested for a particular gap; using oversized seals to hide a poor fit is not a reliable repair.

Which fire safety law applies in Lisburn?
