The rating depends on the timber species and density, frame sections, bead profiles, fixings and the glazing seals used in the test. We build timber screens to a tested specification, or to a formal assessment, and finish them without compromising the intumescent details.
Timber frames need dry conditions on site and acclimatisation before glazing to avoid movement around the glass.
Timber screens are tested with specific species and minimum densities. Softwood substitutions or thinner sections can fall outside the evidence.
Heavier insulating glass may need larger sections; we confirm the frame can carry the chosen build-up.
Building work in England is covered by the Building Regulations 2010, with fire safety guidance in Approved Document B and impact safety guidance for glazing in Approved Document K.
Once a building is in use, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire safety measures, including fire-resisting glazing. The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.
In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.
We cover Harrow and the surrounding postcode districts, including HA2, HA1, HA3, HA0, HA9, HA5. Nearby towns we also serve include Brent, Wembley, Northolt. We cover Harrow as part of our Greater London coverage.

Yes. Hardwood screens are tested to 30 and 60 minutes in many configurations, with the right glass, beads and seals.
Sometimes. If the frame can be shown to be suitable, we can replace non-rated glass and add the correct seals and beads. Where it cannot, replacement is the honest answer.
Yes. We survey and install in Harrow and across Greater London, including the HA2 district and nearby Brent.
