Fire Rated Glass Certified for Liechtenstein’s Strict Fire Safety Standards

For the Principality of Liechtenstein, where building safety regulations align closely with both Swiss and European Union frameworks, the specification of certified fire-rated glazing is a critical engineering requirement. Antifires provides a comprehensive range of fire rated glass solutions that are fully compliant with the EN 13501 classification system and the Swiss SIA 183 standard for fire resistance. These products are designed to meet the rigorous demands of high-rise residential towers in Vaduz, commercial complexes in Schaan, and critical infrastructure throughout the country. By adhering to harmonized European test protocols such as BS EN 1634-1 and BS EN 1364-1, Antifires ensures that every glazing system delivers verifiable Integrity (E), Insulation (I), and Radiation (W) performance. The local adoption of the SIA framework requires that all fire-resistant building elements carry CE marking and are supported by third-party test reports from accredited laboratories. Antifires meets this requirement by providing full documentation for building permit submissions, enabling architects and engineers to navigate Liechtenstein’s stringent approval processes with confidence. For further reference on the Swiss fire safety code, professionals can consult the VKF (Swiss Fire Prevention Association) technical guidelines, which form the basis for local enforcement in Liechtenstein.

Navigating Liechtenstein’s Fire Protection Regulations and EN 13501 Compliance Requirements

Liechtenstein’s fire protection regulations are primarily governed by the Swiss SIA 183 standard, which mandates specific fire resistance ratings for building elements based on occupancy type, building height, and fire load. For non-loadbearing glazed assemblies, the required classification typically follows the EN 13501-2 system, with common ratings including EI30, EI60, and EI120. Antifires products are tested to these exacting criteria, with certified performance data derived from standardized furnace tests. For example, a typical 28mm EI60 panel achieves an integrity rating of 66 minutes and an insulation rating of 64 minutes, comfortably exceeding the 60-minute threshold required for many partition applications. The table below outlines the correlation between Liechtenstein’s typical project requirements and Antifires’ certified glass configurations:

All test reports are issued by accredited third-party laboratories, ensuring full acceptance by local fire safety inspectors in Liechtenstein.

Selecting Fire Rated Glass Grades and Technical Parameters for Liechtenstein Projects

Selecting the appropriate fire-rated glass grade for a Liechtenstein project requires a precise evaluation of both fire resistance duration and thermal insulation performance. Local enforcement mandates that all glazing systems carry CE marking and be backed by test reports from accredited labs such as SP (Sweden) or MFPA (Germany). Antifires offers a range of certified configurations, each with distinct structural compositions. For instance, the 10mm FPOS glass—comprising 3mm float glass, 4mm fire gel, and 3mm float glass—provides integrity up to 135 minutes, making it suitable for integrity-only (E) applications. For projects requiring combined integrity and insulation (EI), the 28mm EI60 panel, built with a multi-layer structure of 6mm glass, 5.5mm gel, 5mm glass, 5.5mm gel, and 6mm glass, delivers 66 minutes of integrity and 64 minutes of insulation. The following list summarizes key selection criteria for Liechtenstein engineers:

  • Fire Resistance Duration: Match the required EI or E rating to the building’s fire compartment size and evacuation strategy.
  • Thermal Insulation: For escape routes and fire doors, choose EI-rated glass with an average temperature rise below 140°C on the unexposed side.
  • Radiation Control: For large glazed areas near fire sources, specify EW-rated glass to limit radiant heat transfer below 15 kW/m².
  • Structural Integrity: Ensure the glass is installed in G.M.S. hollow steel frames with ceramic wool seals (3–6mm, density 210 kg/m³) to maintain system performance.

All fire partition solutions are supplied with full technical documentation for seamless approval.

Integrating Fire Rated Glass into Liechtenstein’s Building Applications and Engineering Demands

Integrating fire-rated glass into Liechtenstein’s diverse building applications demands a systems-level approach that accounts for local environmental and structural conditions. In Vaduz, government office buildings frequently require fire-rated partitions that combine transparency with EI60 performance for open-plan layouts. These systems are engineered to withstand seismic loads typical of the Alpine region, with expansion gaps of 3–5mm filled with ceramic fiber to accommodate building movement. For underground parking garages in Triesen, smoke-control glazing is specified to maintain compartmentation while allowing natural light; Antifires’ 21mm FPOS glass, with 120-minute integrity and 30-minute insulation, is a common choice. In Balzers, hotel corridor fire doors must meet EI90 standards to protect escape routes; the 26mm door glass, achieving 89-minute integrity and 68-minute insulation, is installed in G.M.S. hollow steel frames with intumescent fire seals (20mm × 4mm) to ensure gap sealing under fire conditions. The following list highlights key integration considerations:

  • Seismic Zones: Use flexible ceramic wool seals and M8 anchor bolts at 300mm spacing to absorb structural movement.
  • High-Altitude UV Exposure: Specify multi-layer glass with UV-stable intumescent gel to prevent degradation over time.
  • Smoke Control: Combine fire-rated glass with smoke seals certified to EN 1634-3 for effective smoke containment.
  • Historic Renovations: Custom-fabricate curved or oversized panels to match existing architectural openings while maintaining fire performance.

Antifires provides fire rated glass partitions that are pre-engineered for these demanding scenarios.
