Wales Fire Rated Glass & Certified Fire Doors for BS 476 Compliance

In Wales, fire safety in buildings is governed by the Building Regulations 2010 (Part B), which mandates strict compliance with fire resistance standards for all glazed elements used in compartmentation, escape routes, and fire doors. The primary standard referenced for non-loadbearing glazing assemblies is BS 476 Part 22: 1987, which tests for integrity (E) and insulation (I) performance. Antifires supplies certified fire rated glass and complete door systems that meet these rigorous Welsh requirements. Whether for a new commercial development in Cardiff or a heritage retrofit in Swansea, the selection of glass must account for the specific fire resistance period—typically 30 or 60 minutes—as well as the need for thermal insulation to protect occupants and prevent fire spread. Antifires’ product range, tested to BS 476 and BS EN 1634-1, includes both integrity-only and combined integrity-plus-insulation solutions, ensuring full compliance with local fire safety strategies. For official regulatory guidance, refer to the Welsh Government’s Part B Fire Safety documentation.

Welsh Building Regulations Part B and Fire Safety Compliance for Glazing Systems

Welsh Building Regulations Part B requires that fire-rated glazing systems maintain compartmentation and protect means of escape. Compliance is verified through testing to BS 476 Part 22, which assesses integrity (resistance to flame and hot gas penetration) and insulation (limiting temperature rise on the unexposed side). Antifires’ assemblies are engineered with G.M.S. hollow steel frames, ceramic wool (3–6 mm, density 210 kg/m³), and intumescent fire seals (20 mm × 4 mm) to ensure a stable, gap-free installation. For commercial projects in Wales—such as offices, schools, and healthcare facilities—systems achieving EI30 or EI60 are commonly specified. The fire-rated glass itself, such as the 28 mm EI60 panel (tested to 66 minutes integrity and 64 minutes insulation), provides reliable performance in high-traffic corridors and stairwells. Installers must follow the prescribed expansion gap of 3–5 mm filled with ceramic fiber and use M6/M8 anchor bolts at 300–600 mm spacing to maintain the tested assembly’s integrity.

Selecting Fire Rated Glass Grades for Welsh Heritage and Modern Construction

Wales’ building stock includes both modern commercial centres and historic structures, particularly in cities like Cardiff, Swansea, and Newport. For heritage projects where original window frames must be preserved, Antifires offers thin-profile fire rated glass, such as the 10 mm FPOS (3 mm float + 4 mm fire gel + 3 mm float) which provides 135 minutes integrity and 16 minutes insulation. This allows retrofitting without altering existing timber or metal frames. For new builds or modern renovations requiring higher insulation, the 26 mm door glass (5 mm + 5.5 mm gel + 5 mm + 5.5 mm gel + 5 mm) delivers 89–90 minutes integrity and 68 minutes insulation, ideal for 60-minute escape route doors. The selection process must consider the ambient test temperature (27°C–36°C) and relative humidity (43%–90%) under which the glass was certified, ensuring real-world performance matches laboratory results. Antifires provides fire door systems that are pre-assembled and tested, simplifying specification for Welsh contractors.

Project Demands for Fire Rated Partitions in Welsh Commercial and Public Buildings

In Welsh commercial and public buildings—such as hospitals, shopping centres, and civic offices—fire rated partitions must provide both integrity and insulation to prevent radiant heat transfer and maintain compartmentation. Antifires’ 50 mm and 54 mm ultra-high-performance glass achieves EI120 (120 minutes integrity and up to 120 minutes insulation), making it suitable for high-risk zones like plant rooms and fire-fighting shafts. The multi-layer insulated structure incorporates intumescent gel layers that activate under heat, forming a rigid opaque barrier that blocks flame and heat. For open-plan offices requiring natural light, 21 mm FPOS (120 minutes integrity, 30 minutes insulation) offers a balance between transparency and fire safety. All assemblies are tested with Type K thermocouples (9–12 channels) on the furnace side and 10–55 thermocouples on the unexposed surface, ensuring accurate measurement of temperature rise. Welsh specifiers should also consider fire partition solutions that integrate seamlessly with existing fire door and window systems, providing a unified fire safety strategy across the building.

Why Welsh Contractors Trust Antifires for Certified Fire Rated Solutions

Welsh contractors choose Antifires because every product is backed by certified test data from recognised laboratories, ensuring full compliance with BS 476 Part 22 and BS EN 1634-1. The company’s technical team provides localised support for projects in Wales, from initial specification through to installation guidance. For example, the 6 mm E90 glass (90 minutes integrity) and 8 mm glass system (73 minutes integrity) are commonly used in internal vision panels and doors, while the 15 mm FPOS (up to 132 minutes integrity, 33–34 minutes insulation) serves higher-risk applications. Antifires also supplies fire-rated insulation board (12–15 mm) and ceramic tape to complete the assembly. All products are supplied with detailed installation manuals referencing the exact test conditions (furnace pressure 0 ±2 Pa, ambient temperature 27°C–36°C) under which they were certified. This transparency builds trust and ensures that Welsh contractors can confidently specify Antifires for projects requiring E60, E90, EI60, or EI120 ratings.

Frequently Asked Questions (FAQ)

In Welsh commercial buildings, the required fire resistance rating depends on the building’s height, use, and escape route design. For means of escape, 30 minutes integrity (E30) is often the minimum, while compartment walls and doors typically require 60 minutes (E60 or EI60). Higher-risk areas such as plant rooms or fire-fighting shafts may demand 90 or 120 minutes (E90, EI120). All ratings must be verified through testing to BS 476 Part 22 or BS EN 1634-1. Antifires supplies glass and door systems certified to these standards, ensuring compliance with Wales Building Regulations Part B.

Yes, Antifires provides a full range of certified fire doors and windows that comply with Wales Building Regulations Part B. All assemblies are tested to BS 476 Part 22 and BS EN 1634-1, with ratings from E30 to EI120. Products include integrity-only glass for vision panels and insulated glass for compartment walls. Each system comes with detailed installation specifications and test certificates, giving Welsh contractors and specifiers full confidence in regulatory compliance.

Yes, Antifires supplies thin-profile fire rated glass suitable for historic buildings in Wales. For example, the 10 mm FPOS (135 minutes integrity) and 15 mm FPOS (up to 132 minutes integrity) can be installed within existing timber or metal frames without altering the original architecture. These products are tested to BS 476 Part 22 and provide the required fire resistance while preserving the building’s character. Antifires also offers technical guidance on frame reinforcement and sealant selection to ensure a compliant retrofit.
