Sourcing specialist fire rated glazing for a London project can be a bit of a logistical puzzle. Whether you are searching for a trusted London fire rated windows and doors company for a sensitive heritage refurbishment in Westminster or a fast-paced commercial development in Croydon, finding a team that actually understands the technicalities of fire safety is often half the battle.








We are Aluminium Fire Systems or AFS for short. We are one of the UK’s leading experts in the manufacture and supply of fire rated windows, fire rated doors and fire rated glass partitions. While our manufacturing hub is strategically based at 340 Summer Lane in Birmingham (B19 3QL), we operate as a specialist supplier for the entire UK, with an understanding of the unique demands of projects in the capital.
Being a direct UK manufacturer appears to make a real difference for our London clients. We aren’t just a distant name on a screen; we are hands-on experts building fire rated aluminium windows, fire rated aluminium doors and fire rated glass partitions in-house right here in the UK.
Why Material Choice Matters
In the UK glazing industry, fire resistance is classified into three categories: E (Integrity), EW (Integrity & Radiation), and EI (Integrity & Insulation). At AFS, we have made the strategic decision to move away from ‘E’ and ‘EW’ rated products for developments, focusing exclusively on EI-rated systems.
Standard ‘E’ rated glass is designed to stop flames and smoke (Integrity), but it allows radiant heat to pass through almost instantly. In the event of a fire, the non-fire side of ‘E’ rated glass can reach temperatures high enough to spontaneously ignite furniture or cause severe skin burns to those attempting to escape.
An EI rating provides a thermal barrier. By using an intumescent interlayer that expands when heated, EI glass limits the temperature rise on the protected side, usually to no more than 140°C above ambient temperature.
Our London Fire Rated Windows and Doors Company is committed to EI ratings that ensure your project aligns with the most rigorous safety frameworks:
We manufacture our units using high-specification profiles from Aluprof, a partner with over 70 years of experience.
