London Fire Rated Glass Solutions: Certified for UK Building Safety

London’s built environment—a blend of historic architecture and modern high-rises—demands fire safety solutions that are both rigorous and adaptable. Antifires provides certified fire rated glass, doors, and glazed systems that fully comply with the United Kingdom’s Approved Document B (Fire Safety) and the Building Regulations 2010. These systems are tested to the authoritative standards of BS 476 Part 22: 1987 and BS EN 1634-1: 2014, ensuring passive fire protection for compartmentation, escape routes, and critical structural elements across the capital. Whether for a sensitive listed building retrofit in Kensington or a new commercial tower in the City of London, Antifires’ product range—from 30-minute integrity-only glazing to 120-minute insulated assemblies—offers verified performance. The company’s technical documentation provides full traceability to test data, including certified integrity (E) and insulation (I) ratings, which are essential for satisfying local authority building control approvals. By integrating these systems into a project’s fire strategy, specifiers and contractors can confidently meet the stringent life safety and property protection requirements that define London’s regulatory landscape.

Meeting London’s Fire Safety Requirements Under UK Building Regulations Part B

London’s fire safety framework, primarily governed by Approved Document B, mandates that passive fire protection systems maintain compartmentation and protect means of escape. Antifires’ glazed assemblies are designed to meet these requirements through rigorous testing under BS 476 Part 22 and BS EN 1634-1. For example, a typical 10mm FPOS glass unit—comprising 3mm float glass, 4mm fire gel, and 3mm float glass—achieves an integrity rating of 135 minutes, while providing insulation for 16 minutes. This performance is critical for London’s high-density zones, where fire spread between compartments must be prevented. The systems utilize G.M.S. hollow steel frames with intumescent seals (20mm × 4mm) and ceramic wool (3mm–6mm, density 210 kg/m³) to ensure stable performance under furnace temperatures reaching over 800°C. For projects requiring enhanced thermal performance, such as in energy-efficient new builds, the 50mm ultra-high-performance glass delivers EI120 ratings with U-values optimized for UK energy standards. This combination of fire resistance and thermal efficiency makes these systems suitable for both modern curtain walling and historic window replacements in conservation areas.

Selecting Fire Rated Glass for London’s Climate: E, EI, and EW Classifications

Selecting the correct fire rating classification—E (Integrity), EI (Integrity & Insulation), or EW (Radiation Control)—is essential for London’s variable climate and project-specific demands. For internal partitions and doors where radiant heat is less of a concern, E-rated glass such as the 6mm E90 system (integrity 90 minutes) provides cost-effective compartmentation. In contrast, EI-rated assemblies are required for external glazing or stairwell enclosures where the unexposed side temperature must remain below 140°C (average) or 180°C (maximum). Antifires’ 28mm EI60 panel, for instance, achieves integrity for 66 minutes and insulation for 64 minutes, making it ideal for London’s mixed-use developments. For high-rise residential towers in areas like Canary Wharf, the 26mm door glass (integrity 89–90 minutes, insulation 68 minutes) offers robust protection for escape routes. Additionally, all systems are tested under ambient conditions of 27°C–36°C and relative humidity of 43%–90%, reflecting London’s seasonal variations. This ensures that the intumescent gels and seals perform reliably, whether in a humid summer or a cold winter, without compromising fire safety or structural integrity.

Critical Applications Across London’s Commercial and Residential Projects

Antifires’ products are deployed across London’s most demanding project types. In commercial districts like Canary Wharf and the City of London, fire-rated glazing is specified for stairwell enclosures, lobby partitions, and facade systems in high-rise office towers. The 50mm EI120 glass, with certified integrity and insulation up to 120 minutes, is often used in these contexts to create safe vertical escape routes. For residential conversions in Westminster or listed building retrofits in Marylebone, the 21mm FPOS glass (integrity 120 minutes, insulation 30 minutes) provides a slim-profile solution that respects historical aesthetics while meeting modern fire codes. In healthcare and education facilities, where compartmentation is critical, the 28mm EI60 panels are installed in corridor partitions and door vision panels. All systems are installed using M6/M8 anchor bolts at 300–600mm spacing, with expansion gaps of 3mm–5mm filled with ceramic fiber to accommodate thermal movement. This technical precision ensures that the glazing performs as tested, even under the extreme deflection (up to 152mm toward the furnace) observed during fire tests, maintaining compartment integrity for the required duration.

Why London Specifiers Trust Antifires for Certified Fire Protection

London specifiers and contractors choose Antifires for verifiable compliance and local support. Every product is UKCA-marked and traceable to fire test reports conducted under BS 476 Part 22 and BS EN 1634-1. This documentation is critical for satisfying building control officers and insurers. Antifires maintains local stockholding in London, enabling fast delivery for time-sensitive projects, from office fit-outs in the Square Mile to residential towers in Stratford. The technical team provides on-site support for compliance documentation, installation guidance, and integration with existing fire alarm and sprinkler systems. For example, the company’s 120-minute fire rated glass systems are accompanied by full installation manuals specifying frame profiles, sealant types, and fixing schedules. This level of detail ensures that the as-built performance matches the certified test data. Additionally, Antifires’ 60-minute fire rated glass solutions are widely used in London’s commercial and residential sectors, offering a balance of cost and performance. For projects requiring enhanced thermal and acoustic performance, the 54mm ultra-high-performance glass provides EI120 ratings with U-values below 1.0 W/m²K, meeting the strict energy targets of the London Plan.
