FD30 Internal Fire Doors

The usual triggers are straightforward. A loft conversion or any three-storey house generally needs fire doors onto the stair enclosure. A door between an integral garage and the house needs one. Houses in multiple occupation have their own requirements, and landlords are the group most likely to be inspected on it. If you are unsure whether your project falls into one of these, your building control officer or architect will confirm it — and it is worth asking before the doors are ordered rather than after.

A fire door only performs as a system. The rated leaf is one part; the frame, the intumescent seals that expand to close the gap in a fire, three correctly rated hinges, and a closer where one is required all matter. Fitting also matters more than on an ordinary door: the gap around the leaf has to be within tolerance, and packing out a badly sized opening or trimming beyond the manufacturer's limit can void the rating entirely. That is the main reason we would rather supply and fit these than supply them alone.

Every fire door here carries a 30-minute rating and is hung with the correct ironmongery as part of the installation. If you tell us what the doors are for — loft stair, garage, HMO — we will quote the whole assembly rather than just the leaf, so there is nothing missing on fitting day.
