Where do composite fire doors make sense?
Composite doorsets are widely used as flat entrance doors, both inside corridors and on external deck-access walkways where the door faces the weather. Their factory finish avoids repainting, which matters because paint build-up is a common reason seals stop working. Many products also offer security features alongside the fire rating.
As standard, the work covers:
- FD30S composite doorset made to measure
- Advice on certified composite products and options
- Viewer, numerals and security hardware within evidence
- Certificate reference and photo record
Fire door law for Windsor properties
The rules that apply to fire doors in Windsor are England's. The responsible person under the Regulatory Reform (Fire Safety) Order 2005 must keep fire doors in non-domestic premises and the common parts of flats in working order; the Fire Safety Act 2021 confirmed that this includes flat entrance doors onto common parts.
Where a Windsor block is above 11 metres, regulation 10 of the 2022 regulations means communal doors are checked every three months and flat entrance doors annually on a best-endeavours basis. Replacement doors must also satisfy the Building Regulations, with Approved Document B as the guidance most building control bodies work from.
