Certified FD30 & FD60 Fire Door Specialists
The correct installation of fire-rated doors is a critical component of any fire protection strategy. Golden Ratio Windows provides expert fire-rated door installation across London, ensuring the highest standards of safety and full compliance with UK Fire Safety Order 2005.
Fire-rated doors are specifically designed to impede the spread of fire and smoke, providing vital time for occupants to escape and for emergency services to respond. They compartmentalise buildings and prevent fire spreading rapidly from one area to another.
Crucial Note: A fire door is only as good as its installation. We ensure gap tolerances meet the strict 3mm–4mm industry requirement and every installation is backed by official compliance documentation.
Every fire door installation includes:
We don't just fit doors — we provide life-safety systems. Every fire door installation is backed by rigorous technical standards and official certification for your building insurance.
Certified resistance for 30 minutes, giving occupants vital time to escape. BS 476 Part 22 compliant. Required in most residential and commercial applications.
Extended 60-minute fire resistance for high-risk areas, stairwells, and commercial premises where enhanced compartmentalisation is required.
Precision-fitted heat-expanding seals that swell in fire conditions to block the passage of lethal smoke and toxic gases — embedded strips expand to 25x their size above 200°C.
We only use fire-rated hinges, latches, and self-closing devices tested to operate under extreme heat without failure. All ironmongery is CE marked and fully traceable.
Our fire doors are precision-engineered from the core outward. Every component is specified and installed to meet or exceed UK fire safety standards.
We follow a rigorous three-stage process to ensure every fire door installation is fully compliant, correctly fitted, and officially signed off.

Yes. Fire safety doesn't mean sacrificing style. We offer bespoke timber fire doors that meet FD30 standards while matching Victorian, Edwardian, or contemporary aesthetics.
The strict industry requirement is 3mm–4mm around the door leaf. This ensures the intumescent seals can expand correctly in a fire. We check every installation against this standard before sign-off.
Most single fire door installations are completed within one day, including removal of the existing door, precision fitting, ironmongery installation, and final gap checks.
