Oslo’s TEK17 Fire Compliance and Norwegian Building Code Requirements
Oslo’s TEK17 fire compliance requires that all glazed assemblies in escape routes and fire compartments meet the NS-EN 13501-2 classification, which evaluates both integrity (E) and insulation (I) performance. Antifires products are designed to satisfy these criteria, with systems achieving ratings from EI 30 to EI 120 as verified by accredited test laboratories. The Norwegian building code emphasizes the use of pre-accepted fire designs (preaksepterte løsninger), which simplify approval for standard applications such as corridor partitions and stairwell enclosures. Key technical requirements include:
- Integrity (E): Resistance to flame penetration and hot gas leakage for the specified duration.
- Insulation (I): Limiting temperature rise on the unexposed side to a maximum of 180°C (average 140°C) to prevent fire spread.
- Radiation (W): Control of radiant heat transfer, critical for protecting adjacent combustible materials.
Antifires provides comprehensive documentation, including CE marking and test reports in Norwegian, to facilitate direct acceptance by local building authorities and fire consultants.
Fire Rated Glass Grade Selection and Technical Parameters for Oslo’s Climate
Selecting the appropriate fire rated glass grade for Oslo’s cold climate requires balancing thermal performance with fire resistance. Antifires systems are engineered to meet TEK17’s pre-accepted fire designs, accounting for radiant heat transfer and smoke leakage in mixed-use developments combining timber frames and glass facades. The glass composition utilizes multi-layer structures with intumescent gel interlayers that activate under heat, forming an opaque insulating barrier. For projects in Bjørvika and Nydalen, where energy efficiency is critical, Antifires offers configurations with U-values below 1.0 W/m²K without compromising fire ratings. Technical parameters include:
| Rating | Typical Application | Key Feature |
|---|
| EI 30 | Internal partitions and doors | Lightweight, slim profile |
| EI 60 | Escape routes and compartment walls | Balanced insulation and integrity |
| EI 120 | High-risk areas and stairwells | Extended thermal protection |
All systems are tested under conditions simulating Oslo’s ambient temperature range (27°C–36°C) and high humidity (up to 90%), ensuring reliable performance in real-world scenarios.
Oslo Building Application Scenarios: Commercial, Heritage and Residential Projects
Oslo’s diverse building stock requires fire rated glazing solutions tailored to specific project scenarios, from commercial high-rises to heritage-listed structures. Antifires systems are designed for seamless integration into TEK17-compliant designs, supporting both new construction and retrofit applications. Key application scenarios include:
- Commercial Projects: In developments like Bjørvika’s waterfront, fire rated glass is used for open-plan office partitions and atrium enclosures, requiring EI 60 to EI 120 ratings to maintain compartmentation without sacrificing natural light.
- Heritage Buildings: For Oslo’s historic structures, slim-profile EI 30 systems preserve original aesthetics while meeting modern fire safety codes.
- Residential Projects: In apartment complexes in Nydalen, EI 60 glass doors and windows provide fire separation between units and common corridors, complying with TEK17’s requirements for dwelling compartment walls.
Each installation uses G.M.S. hollow steel frames, ceramic wool seals, and intumescent fire seals to ensure airtight performance and structural stability under fire conditions.
