Certified Fire Rated Glass for Graz: Antifires Solutions Aligned with Austrian Standards

For construction projects in Graz, Austria, compliance with national fire safety regulations is a non-negotiable requirement for building permits and occupancy approvals. Antifires provides certified fire rated glass systems that align precisely with the OIB-Richtlinie 2 (Austrian Institute for Building Technology) and the European classification standard EN 13501-2. These standards govern the fire resistance performance of building elements, including glazed assemblies used in escape routes, fire compartments, and facades. Whether applied in new builds in the Smart City Graz district or sensitive renovations within the UNESCO-protected Altstadt, Antifires systems are engineered to meet local authority requirements for integrity (E) and insulation (I).

Antifires’ product range includes fire door systems, fire partition solutions, and specialized glazing for windows, all tested under rigorous conditions such as BS EN 1634-1 and BS 476 Part 22. The glass compositions, ranging from 10mm to 54mm multi-layer structures, incorporate intumescent gel layers that activate under heat to maintain compartmentation. By integrating these certified assemblies, architects and contractors in Graz can achieve seamless approval processes while ensuring occupant safety. The company’s technical documentation includes references to OIB guidelines and EN test reports, providing verifiable evidence for local building authorities.

OIB Guidelines and Local Fire Safety Compliance for Graz Construction Projects

Graz building permits mandate strict adherence to OIB-Richtlinie 2 (Fire Safety for Buildings), which defines performance criteria for fire-resistant glazing in escape routes, stairwells, and compartment walls. Antifires products are tested to EN 13501-2, ensuring classification under the European system for reaction to fire and resistance. For historic renovations in the Altstadt, where structural modifications are limited, Antifires offers fire rated glass that can be installed within existing steel or timber frames without compromising heritage aesthetics.

Key compliance features include:

  • Integrity (E) and Insulation (I) ratings that match OIB requirements for fire compartments (EI30, EI60, EI90).
  • Tested frame systems using G.M.S. hollow steel sections and ceramic wool seals (3mm–6mm, density 210 kg/m³) to prevent smoke and flame penetration.
  • Certified installation methods with M6/M8 anchor bolts at 300–600mm spacing, ensuring structural stability under fire exposure.

For Graz projects, Antifires provides German-language test certificates and installation guidelines that directly reference OIB-Richtlinie 2, streamlining the approval process with local building authorities.

Fire Rated Glass Grades for Graz: EI Classification and Thermal Performance Parameters

In Graz, fire resistance requirements for escape routes and high-rise buildings—such as those in the Smart City Graz district—demand precise EI classification to match Styrian fire brigade access protocols. Antifires systems deliver certified performance from EI30 to EI90, with thermal insulation parameters that limit temperature rise on the unexposed side to ≤140°C average and ≤180°C maximum, as per EN 13501-2.

Recommended glass structures for Graz applications:

RatingGlass CompositionTypical Application
EI3010mm FPOS (3mm float + 4mm gel + 3mm float)Internal partitions, low-rise offices
EI6028mm (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm)Escape route doors, stairwell enclosures
EI9026mm door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm)High-rise fire compartments, hotel corridors

These systems maintain integrity for up to 135 minutes (e.g., 10mm FPOS: integrity 135 min, insulation 16 min) while controlling radiant heat transmission (W) for occupant safety. For projects requiring extended insulation, the 50mm/54mm EI120 glass offers up to 120 minutes of thermal protection.

Graz Building Applications: Fire Rated Glass for Offices, Hotels and Historic Facades

Graz’s diverse building stock—from modern office towers in the Smart City district to historic facades in the Altstadt—requires adaptable fire rated glass solutions. Antifires systems are designed for seamless integration into various project scenarios:

  • Office buildings: Use EI60 fire partition solutions for open-plan layouts, ensuring compartmentation without sacrificing natural light. The 28mm EI60 panel (integrity 66 min, insulation 64 min) is ideal for corridor glazing.
  • Hotels and mixed-use developments: Install 26mm door glass (integrity 89–90 min, insulation 68 min) in guest room doors and escape route doors to meet OIB requirements for fire resistance.
  • Historic facades: For Altstadt renovations, Antifires offers 21mm FPOS glass (integrity 120 min, insulation 30 min) that can be fitted within existing window frames, preserving architectural character while upgrading fire safety.

Each installation uses ceramic wool (3mm–6mm) and intumescent seals (20mm × 4mm) to maintain performance, with expansion gaps (3mm–5mm) filled with ceramic fiber to accommodate thermal movement.

Antifires Local Expertise: Austrian Certification and Project Support for Graz Clients
