Austrian OIB Guidelines and Vienna Building Code Compliance for Fire Barriers
Vienna’s building projects must comply with the OIB-Richtlinie 2, which mandates fire resistance ratings for structural elements based on building height, occupancy, and fire load. Antifires fire rated glass systems are tested to EN 13501-2 and certified for classifications including EI 30, EI 60, and EI 120, ensuring full adherence to these regulations. The Bauordnung für Wien further specifies requirements for fire compartmentation in escape routes and stairwells, where glazed barriers must prevent flame spread and limit heat transfer. Our products incorporate multi-layer intumescent gel technology between tempered glass panes, which activates at high temperatures to form an opaque insulating barrier. Test data from BS EN 1634-1 and BS 476 Part 22 confirm integrity durations up to 135 minutes and insulation performance up to 120 minutes, depending on glass thickness (e.g., 10mm to 54mm). For Viennese projects, we provide localized conformity declarations and CE marking that align with Austrian approval processes, reducing administrative delays. Typical applications include:
- Stairwell enclosures in office buildings requiring EI 60 fire resistance.
- Atrium separations in commercial developments needing EI 120 performance.
- Listed building renovations where heritage facades must integrate fire-rated glazing.
By referencing OIB guideline test protocols, Antifires ensures that every installation meets Vienna’s strict safety benchmarks.
EI Classification and U-Value Requirements for Fire Rated Glass in Vienna’s Climate
Selecting fire rated glass in Vienna requires balancing fire resistance classification (EI 30, EI 60, EI 90) with thermal insulation (U-value) to comply with Austrian energy performance standards (OIB-Richtlinie 6). Antifires offers multi-layered intumescent glazing with verified test reports from EN 1364-1, demonstrating both fire integrity and thermal efficiency suitable for Vienna’s continental climate, where winter temperatures can drop below -10°C and summer peaks exceed 30°C. Our products achieve U-values as low as 1.1 W/m²K for 50mm insulated units, reducing heat loss while maintaining EI 120 fire resistance. The glass structure incorporates 5mm tempered glass panes with 5.5mm intumescent gel layers, as tested in 26mm door glass configurations that achieved 89 minutes integrity and 68 minutes insulation. For Viennese projects, key considerations include:
- EI 30 glazing for internal partitions in residential buildings, balancing cost and thermal performance.
- EI 60 systems for office stairwells, where U-value compliance supports energy certification.
- EI 120 units for industrial fire compartments, combining high insulation with low thermal transmittance.
Antifires provides thermal performance data sheets alongside fire test certificates, enabling architects to meet both OIB-Richtlinie 2 and OIB-Richtlinie 6 requirements seamlessly.
Application in Viennese Historic Facades and Modern Office Complex Renovations
Vienna’s architectural landscape—from Gründerzeit buildings (19th-century historicist structures) to contemporary high-rises—demands adaptable fire protection solutions. Antifires fire rated glass and fire partition solutions are specified for diverse scenarios:
- Historic facade renovations: In listed buildings, our 10mm FPOS glass (3mm float + 4mm gel + 3mm float) provides 135 minutes integrity while maintaining slim profiles that respect original window frames. Tested under BS 476 Part 22, this system prevents fire spread without altering heritage aesthetics.
- Modern office complex refurbishments: For internal stairwells in Viennese office towers, 28mm EI 60 panels (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) deliver 66 minutes integrity and 64 minutes insulation, meeting OIB requirements for escape routes.
- Atrium separations in new developments: 50mm EI 120 glass, with multi-layer insulated structure, provides 120 minutes integrity and insulation for large-span glazed barriers in commercial atriums.
Each installation uses G.M.S. hollow steel frames with ceramic wool seals (3-6mm, density 210 kg/m³) and intumescent fire seals (20mm x 4mm), ensuring compliance with Bauordnung für Wien for compartmentation and heritage preservation.
Antifires Localized Support: EN-Certified Products and Direct Vienna Project Consultation
Viennese architects and contractors benefit from Antifires’ localized technical support, including German-language conformity declarations and CE marking documentation accepted by Austrian building authorities. Our service includes:
- Project-specific fire engineering advice: We analyze building height, occupancy type, and fire load to recommend appropriate EI 30 to EI 120 classifications, referencing OIB-Richtlinie 2 test protocols.
- Sample delivery and compliance verification: Antifires provides fire test certificates from accredited labs (e.g., BS EN 1634-1, ASTM E119) and thermal performance data for energy code compliance.
- Reduced approval timelines: Pre-prepared documentation, including installation manuals with frame specifications (M6/M8 anchor bolts at 300-600mm spacing) and expansion gap details (3-5mm ceramic fiber), streamlines municipal approvals in Vienna.
For a recent Viennese hotel project, Antifires supplied 28mm EI 60 door glass with 89 minutes integrity and 68 minutes insulation, meeting both fire safety and acoustic requirements.
