Norway Fire Rated Glass and Certified Building Safety Systems for Oslo Projects

In the demanding landscape of Norwegian construction, ensuring fire safety compliance for glazed assemblies requires a deep understanding of both local regulations and international testing standards. For projects in Oslo and across Norway, specifying fire rated glass that meets the rigorous demands of TEK17 (Byggteknisk forskrift) is not optional—it is a legal and safety imperative. TEK17 mandates specific fire resistance classes, ranging from EI 30 to EI 120, for elements such as escape route enclosures and compartment walls, directly referencing the European classification system EN 13501-2 for performance verification.

Antifires provides a comprehensive portfolio of certified glazing solutions that align seamlessly with Norway’s national pre-accepted solutions, facilitating smoother approval processes with local building authorities. Whether the requirement is for integrity-only (E) or combined integrity and insulation (EI) performance, each system is backed by documented test data from standards like BS 476 Part 22 and BS EN 1634-1. This ensures that architects and specifiers in Oslo can confidently design for high-rise residential towers, commercial complexes, and public infrastructure without compromising on safety or aesthetic transparency. By integrating official standards such as NS 3919 and referencing guidance from the Directorate for Building Quality (DiBK), Antifires delivers solutions that are technically validated and locally accepted. For a deeper understanding of how these systems apply to specific project types, explore our range of fire partition solutions designed for demanding commercial environments.

Norwegian Building Regulations TEK17 and Fire Class Requirements for Glazed Assemblies

Norway’s building regulations, particularly TEK17, establish a strict framework for passive fire protection, requiring glazed assemblies in critical areas to achieve defined fire resistance classes. These classes, such as EI 30, EI 60, and EI 120, are based on the European standard EN 13501-2, which classifies products according to their performance in integrity (E) and insulation (I). For glazed elements used in escape routes and fire compartment walls, compliance with these classifications is mandatory to ensure safe evacuation and contain fire spread.

The Norwegian standard NS 3919 further refines the requirements for fire-resistant glazing, specifying criteria for both integrity and thermal insulation that must be documented through certified test reports. Antifires products are engineered to meet these exacting standards, using multi-layer glass compositions with intumescent gels that activate under heat to create a robust insulating barrier. For instance, systems achieving EI 60 performance—such as a 28mm composite panel—demonstrate the ability to limit temperature rise on the unexposed side to an average of ≤140°C and a maximum of ≤180°C, as per test protocols. This technical alignment ensures that specifiers can submit documentation that satisfies local building authorities without the need for costly project-specific retesting. For applications requiring only integrity, such as certain internal partitions, our 60-minute integrity-only glass offers a certified solution that meets TEK17’s performance demands.

Selecting EI 30 to EI 120 Fire Rated Glass for Norwegian Climate and Structural Loads

Selecting the appropriate fire-rated glass for Norwegian projects involves balancing fire performance with the unique climatic and structural conditions of the region. Oslo’s cold climate, characterized by significant temperature differentials between interior and exterior environments, demands glazing systems that minimize thermal bridging while maintaining certified fire resistance. The Directorate for Building Quality (DiBK) requires documented performance for high-rise residential and commercial towers, where stairwell enclosures and atrium perimeters are critical to life safety.

Antifires offers a range of solutions from EI 30 to EI 120, each designed to meet the specific thermal and structural loads of Norwegian buildings. For stairwell enclosures, where insulation performance is vital to prevent heat transfer, a 21mm multi-layer composite insulated fire-resistant glass provides 120 minutes of integrity and 30 minutes of insulation, as verified by standard test conditions. For projects requiring higher insulation values, such as those in the Barcode district, a 50mm ultra-high-performance glass system achieves EI 120 with full insulation for the entire duration. The frame systems utilize G.M.S. hollow steel sections with ceramic wool and intumescent seals, ensuring that the entire assembly—not just the glass—performs under fire exposure. To further enhance energy efficiency in cold climates, these systems can be integrated with low U-value configurations, making them suitable for exterior applications where thermal performance is as critical as fire safety. For comprehensive project specifications, review our 120-minute fire-rated glass for walls and partitions.

Oslo Commercial Towers and Stavanger Offshore Facilities: Fire Rated Glazing Project Demands

The architectural demands of Oslo’s Barcode district skyscrapers and Stavanger’s offshore facilities present unique challenges for fire-rated glazing. In high-rise commercial towers, atrium perimeters often require EI 60 fire windows to contain smoke and flames while maintaining visual connectivity. Antifires installations have successfully passed DiBK inspections for over 15 high-rise projects, demonstrating consistent compliance with Norwegian building codes. These systems utilize frames fabricated from Norwegian-sourced steel profiles, which are engineered to prevent thermal bridging—a critical factor in maintaining both fire integrity and energy efficiency in cold climates.

For offshore facilities in Stavanger, where harsh marine environments and stringent safety regulations apply, the glazing must resist both fire and corrosive conditions. Antifires provides assemblies that incorporate fire-rated insulation boards (12mm–15mm) and ceramic fiber expansion gaps (3mm–5mm), ensuring structural stability under fire exposure. The test behavior of these systems, including controlled glass cracking within 2–4 minutes and subsequent intumescent gel activation, is well-documented. Maximum deflection toward the furnace is monitored, typically ranging from 38mm to 152mm, ensuring that the assembly maintains its barrier function. For project-specific requirements, such as those in Stavanger’s offshore sector, Antifires can tailor the frame and sealant specifications to meet both fire resistance and environmental durability standards.

Antifires Local Technical Support and EN-Certified Product Consistency for Norwegian Specifiers

Antifires provides Norwegian specifiers with comprehensive local technical support, ensuring that every project benefits from expert guidance and EN-certified product consistency. The Oslo-based technical team offers on-site fire testing demonstrations, allowing architects and contractors to witness the performance of EI 30 to EI 120 assemblies under controlled conditions. This hands-on approach, combined with Norwegian-language documentation, eliminates translation errors that can complicate compliance submissions. All products are backed by SINTEF verification for fire resistance, a key requirement for acceptance by local building authorities and insurance companies.

The technical support extends to detailed installation guidance, covering critical aspects such as frame fixing with M6/M8 anchor bolts at 300–600mm spacing and the correct application of intumescent fire seals (20mm × 4mm). This ensures that the installed system performs exactly as tested, maintaining its certified fire resistance. For Norwegian projects, this level of support is invaluable, as it reduces the risk of non-compliance and project delays. Antifires also provides access to full test reports from accredited laboratories, including data from furnace tests using Type K thermocouples and 9–12 channels, ensuring transparency and traceability. This commitment to local expertise and certified product consistency makes Antifires a trusted partner for specifiers across Norway, from Oslo’s commercial towers to Stavanger’s industrial facilities.
