Adhering to Leeds Building Fire Safety Regulations Under Approved Document B
Leeds commercial developments, including office towers, retail centres, and educational facilities, must strictly adhere to the fire safety requirements outlined in Approved Document B. This regulation mandates that fire-resisting glazing used in escape routes and compartment walls must provide both integrity and, in many cases, thermal insulation to prevent the spread of fire and smoke. For example, a glazed partition forming part of a protected corridor must achieve a minimum EI30 rating (30 minutes of integrity and insulation) to allow occupants sufficient time to evacuate. For higher-risk areas, such as stairwell enclosures in high-rise buildings, EI60 or EI120 rated systems are often required. Antifires' certified products, such as the 28mm EI60 panel (tested to 66 minutes integrity and 64 minutes insulation) and the 50mm/54mm EI120 systems, are engineered to meet these demanding criteria. These systems utilise multi-layer composite structures with intumescent gels that activate under heat, forming an opaque insulating barrier that prevents radiant heat transfer and structural failure. By aligning with these local regulations, architects and contractors in Leeds can ensure their projects meet the legal standards for fire safety without compromising on design or transparency.
Selecting EI and EW Fire Rated Glass Grades for Leeds Climate and Building Types
Selecting the appropriate fire rated glass grade for a Leeds project requires a detailed understanding of the building's fire strategy, occupancy type, and structural design. For high-rise residential and commercial projects, the BS 9999:2017 code of practice for fire safety in the design, management, and use of buildings provides a framework for selecting performance levels. This standard often recommends EW (integrity and radiation control) or EI (integrity and insulation) rated glazing for phased evacuation strategies. For instance, in a Leeds office conversion, a 26mm door glass system (tested to 89 minutes integrity and 68 minutes insulation) is ideal for fire doors requiring both high impact resistance and thermal performance. Conversely, for internal partitions where only flame containment is critical, an E90 integrity-only glass (tested to 90 minutes) may be sufficient. The table below outlines typical applications for different ratings in Leeds building types:
| Rating |
Typical Leeds Application |
Key Performance |
| E60 |
Internal partitions in low-risk areas |
Flame containment only |
| EI30 |
Protected corridors, small office compartments |
Flame + heat containment |
| EI60 |
Stairwell enclosures, high-rise residential |
Extended evacuation time |
| EI120 |
Compartment walls in large commercial blocks |
Maximum fire separation |
This systematic approach ensures that the glazing solution matches the specific fire risk profile of the building, optimising both safety and cost.
Addressing Fire Safety in Leeds’ Historic Mills and Contemporary Mixed-Use Developments
Leeds is characterised by a unique architectural heritage, including historic mills and industrial buildings now being converted into contemporary mixed-use developments. These projects present distinct fire safety challenges. In a listed building conversion, the original structural elements, such as timber beams and stone walls, may not meet modern fire resistance standards. Here, fire rated glass partitions can be strategically installed to create fire compartments without altering the historic fabric. For example, a 21mm FPOS system (tested to 120 minutes integrity and 30 minutes insulation) can be used to enclose a new stairwell within an old mill, providing a modern fire escape route that is visually unobtrusive. In contemporary mixed-use developments, which combine retail, office, and residential spaces, the need for flexible, high-performance glazing is paramount. EI60 and EI120 rated systems, such as the 50mm ultra-high-performance glass, allow for large, open-plan designs while maintaining strict fire compartmentation between different uses. These systems are installed using robust G.M.S. hollow steel frames with intumescent fire seals and ceramic wool to ensure a complete fire barrier. By addressing both heritage constraints and modern design ambitions, Antifires provides solutions that are technically sound and architecturally sensitive for Leeds' diverse building stock.
Why Leeds Architects and Contractors Trust Antifires for Fire Resistant Glazing
Leeds architects and contractors consistently choose Antifires for fire resistant glazing due to the company's unwavering commitment to certified performance, technical expertise, and project-specific support. Every product supplied is backed by rigorous third-party testing to BS 476 Part 22 and BS EN 1634-1, providing verifiable proof of compliance for building control approvals. The technical team offers detailed guidance on frame specification, sealant selection, and installation methodology, ensuring that the entire glazed system performs as intended under fire conditions. For example, the use of ceramic tape (3mm–6mm, density 210 kg/m³) and intumescent seals (20mm × 4mm) is specified to maintain integrity during thermal expansion. Furthermore, Antifires provides comprehensive documentation, including test certifications and installation manuals, which are essential for project handover and future inspections. For complex Leeds projects, such as the conversion of a historic mill or a large-scale commercial development, the company can offer site-specific support to address unique fire strategy requirements. This combination of certified products, deep technical knowledge, and practical support makes Antifires a trusted partner for ensuring fire safety in Leeds' built environment.
