Sheffield Fire Rated Glass Certified for UK Building Regulations Compliance

Sheffield’s commercial and industrial building sectors demand fire safety solutions that rigorously comply with UK Building Regulations, particularly Approved Document B. For glazed elements used in escape routes, compartment walls, and fire-resisting doorsets, the performance standard is defined by BS 476 Part 22: 1987, which governs the fire resistance of non-loadbearing glazing assemblies. Antifires supplies a comprehensive range of fire rated glass, door systems, and partition solutions that have been independently tested to this standard, ensuring verified integrity (E) and insulation (I) performance for projects across the city. Whether specifying for a new high-occupancy office tower or a refurbished industrial unit, specifiers must ensure that glazing products carry demonstrable third-party certification aligned with these local regulatory requirements. Antifires supports this compliance by providing full UKCA marking documentation and detailed test reports. For further official guidance on fire safety design, professionals can reference the UK Government’s Approved Document B directly. This localized approach ensures that every installation meets the stringent expectations of Sheffield’s building control authorities, safeguarding both life and property.

Meeting Sheffield’s Fire Safety Requirements Under Approved Document B and BS 476

Sheffield’s commercial developments, including office complexes, retail centres, and educational institutions, must adhere to the compartmentation and escape route requirements of Approved Document B. This regulation mandates that glazed elements in fire-resisting walls and doors provide a minimum period of fire resistance, often requiring both integrity (E) and insulation (I) ratings. Antifires products are tested under BS 476 Part 22 to deliver certified performance, with options ranging from E60 (integrity only) to EI120 (integrity and insulation). For high-occupancy buildings, controlling heat transfer is critical; insulation ratings ensure that the unexposed side of the glass remains below the maximum average temperature rise of 140°C. The table below outlines typical system configurations for Sheffield commercial applications:

Product Type Rating (BS 476) Typical Application
21mm FPOS Composite EI60 Compartment walls & stairwells
26mm Glazed Door Glass EI60 Fire door vision panels
10mm FPOS Laminated E90 Corridor partitions (integrity only)

These systems incorporate G.M.S. hollow steel frames and intumescent fire seals (20mm × 4mm), ensuring a robust barrier against smoke and flame propagation.

Selecting Fire Rated Glass Integrity and Insulation Grades for Sheffield’s Industrial Zones

Sheffield’s industrial zones, encompassing manufacturing plants, logistics warehouses, and specialist fabrication units, present unique fire safety challenges. Glazed elements in these environments must resist not only flame penetration but also thermal shock from adjacent high-temperature processes. Antifires provides fire rated glass solutions classified under EN 13501-2, with E (integrity) and EI (insulation) ratings from 30 to 120 minutes. For warehouse partitions and factory viewing panels, the laminated ceramic structure of products like the 15mm FPOS offers proven resilience, with test data showing integrity up to 132 minutes and insulation for 33–34 minutes. Key material specifications for industrial installations include:

  • Frame system: G.M.S. hollow steel sections with ceramic wool (3–6mm, density 210 kg/m³) for thermal break.
  • Expansion management: 3–5mm gaps filled with ceramic fibre to accommodate structural movement.
  • Fixing spacing: M6 or M8 anchor bolts at 300–600mm centres for secure mounting.

These configurations ensure that fire rated glass assemblies maintain their integrity under the demanding conditions typical of Sheffield’s industrial sector, where fire loads can be higher and evacuation routes longer.

Retrofitting Fire Rated Windows and Doors in Sheffield’s Heritage and Modern Office Towers

Sheffield’s architectural landscape is a blend of Victorian-era mills and contemporary glass-clad office towers, each requiring fire rated glazing that respects aesthetic intent while meeting safety codes. For retrofitting fire rated windows and doors in listed buildings, Antifires supplies systems that integrate seamlessly with existing masonry and steel structures. The 28mm EI60 panel, for instance, delivers integrity for 66 minutes and insulation for 64 minutes under BS 476, while its multi-layer laminated construction (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) maintains a slim profile suitable for heritage sightlines. In modern office towers, 50mm and 54mm ultra-high-performance glass provides up to EI120 ratings, ideal for large-span atrium partitions. Key installation considerations for both scenarios include:

  • Frame integration: Use of fire-rated insulation board (12–15mm) behind steel frames to prevent heat transfer.
  • Sealant systems: Ceramic tape and intumescent seals at all perimeter joints to maintain continuity.
  • Deflection allowance: Test data indicates maximum deflection of 38–152mm toward the furnace; frames must accommodate this without failure.

This approach allows specifiers to achieve BS 476 compliance without compromising the architectural character of Sheffield’s diverse building stock.
