Zurich Fire Rated Glass Certified for Swiss and EN Building Compliance

Zurich, as a leading financial and construction hub in Switzerland, enforces some of the most stringent fire safety regulations in Europe. For architects, specifiers, and building owners, ensuring that passive fire protection systems meet both Swiss VKF/Brandschutzrichtlinien (Swiss Cantonal Fire Prevention Association guidelines) and the SIA 183 standard (Swiss Society of Engineers and Architects) is non-negotiable. Antifires supplies certified fire rated glass and glazed systems that are fully compliant with these local codes, as well as the overarching European EN 1363 and EN 1634-1 test standards. These regulations demand that glazing in Zurich’s mixed-use high-rises, transit infrastructure, and heritage-adjacent structures achieve specific EI (Integrity + Insulation) ratings, typically ranging from EI 30 to EI 90. By referencing the official VKF Brandschutzrichtlinien documentation, Antifires ensures that every product specification aligns with the localized requirements for compartmentation, escape route protection, and radiant heat control. This commitment to certified compliance provides Zurich’s construction industry with verifiable, audit-ready documentation for building permit approvals.

Zurich Building Fire Codes and Swiss Norm SIA 183 Compliance Requirements

Switzerland’s fire safety framework is defined by the VKF/Brandschutzrichtlinien (Cantonal Fire Prevention Directives) and the technical specifications of SIA 183:2011, which governs fire protection in building construction. For Zurich projects, these standards mandate that fire-rated glazing must be tested to EN 1364-1 for non-loadbearing walls and EN 1634-1 for door assemblies. The key performance criteria are Integrity (E)—preventing flame and hot gas penetration—and Insulation (I), which limits the average temperature rise on the unexposed side to ≤140°C and the maximum to ≤180°C. Zurich’s building authorities require third-party certification for all glazing systems, with documentation proving the glass’s ability to maintain compartmentation for durations such as 30, 60, or 90 minutes. Antifires’ product range, including 60-minute fire rated glass with integrity and insulation, is engineered to meet these exact thresholds. The systems utilize multi-layer intumescent gel technology that activates under heat, forming a rigid insulating barrier. This ensures compliance not only with Swiss norms but also with the rigorous ASTM E119 and AS1530.4 standards for international consistency.

Fire Rated Glass Classification and Technical Specifications for Zurich Projects

For Zurich’s diverse building stock—from modern office complexes to protected Altstadt structures—fire-rated glazing must deliver precise technical performance. Antifires classifies its products according to the EN 13501-2 standard, providing clear EI 30, EI 60, and EI 90 ratings. The glass composition is critical: for example, the 28mm EI60 panel (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) achieves an integrity of 66 minutes and insulation of 64 minutes under furnace test conditions. For higher-demand applications, the 50mm and 54mm ultra-high-performance glass delivers EI 120 ratings, with both integrity and insulation sustained for 120 minutes. The table below summarizes key classifications for Zurich projects:

RatingGlass ThicknessIntegrity (min)Insulation (min)Typical Application
EI 3010mm FPOS13516Internal partitions, low-rise offices
EI 6028mm6664Escape routes, stairwells
EI 9026mm door glass89–9068High-rise compartmentation
EI 12050–54mm120120Industrial, critical infrastructure

Installation in Zurich requires adherence to specific frame and sealant specifications: G.M.S. hollow steel sections, 12–15mm fire-rated insulation board, and 3–6mm ceramic wool (density 210 kg/m³) for expansion gaps. These parameters ensure that the glass system performs as certified under real-world fire conditions.

Zurich Building Applications: Office Complexes, Transit Hubs, and Mixed-Use Developments

Zurich’s urban landscape presents unique fire protection challenges across multiple project types. In office complexes and mixed-use developments, fire-rated glazing is essential for creating safe compartmentation between commercial and residential zones. Antifires systems, such as the fire partition solutions, are designed for high-traffic areas where transparency must not compromise safety. For transit hubs like Zurich Hauptbahnhof or airport extensions, glazing must withstand crowd pressure and provide clear visibility for wayfinding while maintaining EI 60 to EI 90 ratings. In these scenarios, the glass’s deflection behavior—typically 38mm to 152mm toward the furnace during testing—is factored into structural framing calculations. A critical application is retrofitting historic buildings in Zurich’s Altstadt. These structures often have non-standard openings and load-bearing limitations. Antifires provides custom-sized fire-rated glass and door assemblies that integrate with existing masonry without altering the facade. The use of 3–5mm expansion gaps filled with ceramic fiber ensures thermal movement is accommodated, preserving both heritage aesthetics and modern fire safety. For each project, Antifires supplies a full compliance package, including test reports per BS 476 Part 22 and EN 1634-1, to satisfy Zurich’s building permit requirements.

Antifires Brand Assurance: Swiss-Certified Fire Protection and Local Technical Support

Antifires distinguishes itself in the Zurich market through a combination of Swiss-certified product performance and localized technical support. Every glazing system is tested in accredited laboratories to standards including BS 476 Part 22, EN 1364-1, and EN 1634-1, with certified ratings from E 60 to EI 120. The company’s technical team provides on-site consultation for Zurich projects, assisting with frame selection, sealant specification, and installation protocols. This includes guidance on using intumescent fire seals (20mm × 4mm) and M6/M8 anchor bolts at 300–600mm spacing to meet local building codes. For architects working in Zurich’s protected zones, Antifires offers documentation that directly references the VKF Brandschutzrichtlinien and SIA 183 requirements, streamlining the approval process. The brand’s commitment to quality is evident in its use of multi-layer tempered glass with intumescent gel, ensuring that even under extreme furnace conditions (ambient test temperatures of 27°C–36°C and relative humidity of 43%–90%), the glass maintains integrity and insulation. By providing a single-source solution—from product specification to final certification—Antifires delivers the reliability that Zurich’s construction industry demands.
