Loft conversion fire doors for Castlereagh buildings

A loft conversion in Castlereagh that adds a new storey often brings a building control requirement for fire doors on rooms off the stair. We can fit loft conversion fire doors in Castlereagh as your builder's subcontractor or directly for you.
FD20 or FD30?
In England, the guidance generally asks for FD20 (E20) doors in this situation, and self-closers are not usually required within a house. Scotland is different: the domestic Technical Handbook expects doors onto the protected stair enclosure to be self-closing fire doors, so closers are part of the job there. Many homeowners choose FD30 doors anyway, because they are widely available and the price difference is small. Either way, the door must be fitted properly: correct gaps, fire-tested hinges and an intumescent strip where the product requires one.
On a typical job that means:
- Work coordinated with your builder
- Product details for building control
- Fire-tested hinges and intumescent strips as required
- Check of which openings need fire doors

Do loft conversion fire doors need closers?
Not usually within a single-family house in England. In Scotland, doors onto the protected stair enclosure are expected to be self-closing. Wales and Northern Ireland have their own guidance, and your building control body may ask for something different in particular layouts.
Do all my doors need to be fire doors after a loft conversion?
Usually the doors from habitable rooms onto the stair do, on every floor. Bathrooms are often excluded. Building control decides for your house.
