Edinburgh Fire Rated Glass Solutions: Fully Certified to Scottish Building Standards

Edinburgh's construction and renovation projects are governed by the stringent requirements of the Building (Scotland) Act 2003, which mandates a Building Warrant for all building work. Central to this approval process is compliance with Section 2 (Fire) of the Scottish Technical Handbook, which dictates the performance of passive fire protection systems. For architects, contractors, and building owners in the Scottish capital, specifying the correct fire rated glass is critical to achieving the necessary fire resistance for compartmentation, escape routes, and glazed elements. Antifires provides fully certified glazing solutions tested to BS 476 Part 22: 1987, the primary standard for non-loadbearing glazing assemblies in the UK. This standard rigorously assesses both Integrity (E)—resistance to flame and hot gas penetration—and Insulation (I)—limiting temperature rise on the unexposed side to a maximum average of 140°C. By aligning with these official test protocols, Antifires ensures that every fire door system and glazed partition submitted for warrant approval in Edinburgh is backed by verifiable, third-party test data, directly supporting the fire safety strategy required by local authorities.

Navigating Edinburgh’s Building Warrant Fire Safety Compliance for Glass and Doors

Edinburgh’s planning system demands rigorous fire safety documentation as part of any Building Warrant application. For glazed elements, this requires demonstrating compliance with the fire resistance levels (FRLs) specified in the project’s fire strategy. Antifires’ fire rated glass systems are specifically tested to BS 476 Part 22: 1987, a standard fully recognized by the Scottish Building Standards Department. This standard evaluates a glazing assembly’s ability to maintain compartmentation and protect means of escape. For example, an E60 rating ensures 60 minutes of integrity, preventing flame and hot gas passage, while an EI60 rating adds thermal insulation, limiting heat transfer. Test data from our certified assemblies—such as the 26mm door glass achieving Integrity 89–90 minutes and Insulation 68 minutes—provides the precise performance evidence required for warrant submissions. These certified results, obtained under controlled furnace conditions with Type K thermocouples and specific pressure regimes (0 ±2 Pa), offer Edinburgh specifiers the authoritative documentation needed to satisfy local authority scrutiny for both new builds and complex retrofits.

Specifying EI-Class Fire Rated Glass for Edinburgh’s Mixed-Use and Civic Projects

Edinburgh’s architectural landscape is defined by its historic tenements, sandstone buildings, and modern mixed-use developments. Specifying EI-class fire rated glass is essential for projects that must balance strict fire safety with aesthetic preservation. The Scottish Technical Handbook, Section 2 (Fire), outlines the need for both integrity and insulation in many compartment walls and escape routes. Antifires addresses this with products like the 28mm EI60 panel, which delivers Integrity 66 minutes and Insulation 64 minutes, providing a robust barrier against fire spread while maintaining visual transparency. For more demanding applications, the 50mm and 54mm ultra-high-performance glass achieves EI120, offering up to 120 minutes of both integrity and insulation. These systems are engineered with multi-layer structures—incorporating intumescent gel layers between tempered glass panes—to activate during a fire, forming an opaque, insulating shield. This performance is critical for Edinburgh’s mixed-use projects where ground-floor commercial spaces require fire separation from upper-level residential units, ensuring passive protection without compromising the building’s historic character.

Addressing Fire Protection Demands in Edinburgh’s Listed Buildings and University Estates

Edinburgh’s listed buildings and university estates present unique fire protection challenges, requiring solutions that respect historic fabric while meeting modern safety codes. From the Royal Mile’s historic conversions to the University of Edinburgh’s laboratory extensions, Antifires’ fire rated windows and doors are designed to integrate with existing stonework and steel frames. These projects often require Listed Building Consent alongside a Building Warrant, demanding glazing that preserves traditional sightlines and aesthetics. Our systems, such as the 10mm FPOS (Integrity 135 min, Insulation 16 min) and 21mm FPOS (Integrity 120 min, Insulation 30 min), can be installed within custom steel or timber frames that match existing profiles. The installation process uses ceramic wool (density 210 kg/m³) and intumescent fire seals (20mm × 4mm) to maintain fire performance while accommodating thermal movement. This approach ensures that Edinburgh’s architectural heritage is preserved without compromising the fire engineering strategy required for safe occupation and egress.

Why Edinburgh Architects and Contractors Trust Antifires for Fire Rated Glazing

Architects and contractors in Edinburgh choose Antifires for a clear reason: our products carry UKCA marking and are supported by comprehensive test documentation that is directly accepted by the Edinburgh Building Standards Department. Every system, from 60-minute fire rated glass to EI120 assemblies, is tested under controlled conditions per BS EN 1634-1 and BS 476 Part 22, with full traceability to the original furnace data. This includes detailed records of furnace thermocouple placement (9–12 Type K channels), unexposed surface monitoring (10–55 thermocouples), and ambient test conditions (27°C–36°C). Beyond certification, Antifires offers local technical support, including site-specific fire strategy reviews to ensure the selected glazing aligns with the project’s compartmentation and escape route requirements. With rapid delivery schedules tailored to Scotland’s capital, Antifires provides a complete, trusted solution for Edinburgh’s demanding fire protection needs.

Frequently Asked Questions (FAQ)

All Antifires fire rated glass products are tested to BS 476 Part 22: 1987 and BS EN 1634-1: 2008/2014, the primary standards for non-loadbearing glazing and door assemblies in the UK. These standards evaluate both Integrity (E)—resistance to flame and hot gas penetration—and Insulation (I)—limiting temperature rise on the unexposed side to a maximum average of 140°C. For Edinburgh Building Warrant approval, this test data provides the authoritative evidence required by the Scottish Technical Handbook, Section 2 (Fire). Antifires also offers products tested to ASTM E119 and AS1530.4 for international projects, ensuring full compliance with local regulatory frameworks.

Yes, Antifires supplies fire rated glass solutions that can be customized to replicate the appearance of traditional sash and case windows common in Edinburgh’s historic architecture. Our systems, such as the 10mm FPOS and 21mm FPOS multi-layer composite glass, can be installed within slim-profile steel or timber frames that match traditional sightlines. These assemblies achieve certified fire ratings (e.g., Integrity 120–135 minutes) while maintaining visual clarity. The use of ceramic wool and intumescent seals ensures the glazing integrates seamlessly with existing stonework, supporting both Listed Building Consent and Building Warrant applications.
