An exhaustive guide to navigating TEK17 passive fire protection regulations, marine corrosion prevention, thermal isolation dynamics, and custom profile fabrication for Scandinavian specifiers.
Designing fenestration solutions for the Norwegian market requires reconciling two physically opposing performance imperatives: structural fire protection (Brannsjekk under TEK17) and extreme thermal retention (U-verdi isolation). Under Norway’s Byggteknisk forskrift (TEK17), specifically Section 11 (Forhåndssikring mot brann), building envelopes in high-density urban infills (e.g., Oslo, Bergen, Trondheim) or multi-story timber constructions must prevent fire spread across exterior walls separated by less than 8 meters.
Traditional non-insulated steel frames conduct cold rapidly, generating severe thermal bridges that result in internal frame condensation, ice buildup, and structural frost damage during sub-zero Scandinavian winters. Conversely, standard unreinforced aluminum profiles lose structural integrity above $600^\circ\text{C}$. Our advanced fireproof window factories resolve this conflict through engineered 6063-T6 aluminum alloys fused with internal steel reinforcing cores and multi-chambered PA66 GF25 fiberglass-reinforced polyamide thermal breaks.
To accurately specify fenestration in accordance with NS-EN 13501-2 and NS-EN 16034, architects and general contractors in Norway must distinguish between the three primary fire safety performance metrics:
Why raw material purity and continuous corner welding dictate fire resistance longevity under extreme wind-driven loads.
We do not use secondary contaminated scrap for structural fire frames. Utilizing virgin 99.97% pure A00 grade primary aluminum ingots alloyed with precise silicon and magnesium ratios (6063-T6), our extrusions offer uniform grain structure, eliminating micro-cracking risks under extreme thermal stress expansion.
Unlike standard windows assembled with mechanical crimps or plastic corner keys that warp and open water gaps under fire conditions, every frame and sash member in our facility is Sigma Welded at every joint. The corner becomes a single monolithic metallic piece, holding structural integrity even under intense heat load.
Our fireproof glass units utilize multi-laminated clear float glass separated by clear, hydrated potassium silicate layers. When temperatures reach $120^\circ\text{C}$, these interlayers foam up into an opaque, rigid heat shield, converting radiant energy into endothermic chemical reactions that block heat transmission.

Tailored window engineering configurations solving real-world microclimate challenges in Scandinavian regions.
Urban density regulations in central Oslo enforce strict EI30 or EI60 fenestration barriers on property lines closer than 8 meters. Our narrow sightline aluminum casement and fixed frames allow architects to retain maximum daylighting ratio while meeting 100% of Norsk Standard NS 3904 fire safety requirements.
Structures situated along the wind-battered western Norwegian fjords face relentless salt fog, driving rain, and sub-zero squalls. We supply C5-M high-salinity anodized profile finishes combined with 316-stainless steel multi-point locking hardware, preventing galvanic corrosion while preserving EI60 fire protection.
In Northern Norway, extreme temperature differentials ($\Delta T > 45^\circ\text{C}$) create thermal stress that causes subpar window frames to warp. Our PA66 GF25 thermally broken fireproof units maintain structural stability, blocking heat escape and eliminating frame frosting during severe polar nights.
Addressing essential technical, logistics, and certification queries for fenestration imports to Norway.
Our fire-rated window systems are fully tested in accredited European laboratories in accordance with NS-EN 1363-1, NS-EN 1364-1, and NS-EN 16034 standards. We supply complete CE marking documentation, Declaration of Performance (DoP), and test reports required by Norwegian building controllers (Kommunal bygningsmyndighet) and SINTEF Byggforsk guidelines for TEK17 compliance.
Traditional non-insulated steel windows offer excellent fire integrity but poor thermal insulation, leading to severe frame condensation ("sweating") and high energy losses in Norwegian winters. Our thermally broken aluminum fireproof windows incorporate high-grade structural polyamide barriers and internal cooling compounds, providing low U-values (down to 0.78 W/m²K) without compromising EI60 or EI90 fire resistance.
Yes. Every single window unit is engineered directly from your submittal shop drawings. There are no standard stock size limitations. We specialize in custom opening sizes, fixed glazed curtain wall units, tilt-and-turn configurations, continuous glass facades, and specialized radius-head profiles welded to millimeter precision.
We provide full export-grade crating for sea freight. Every glass unit is edge-protected, wrapped in moisture-barrier film, and packed inside fully enclosed steel-reinforced wooden crates. Shipments land directly at major Norwegian freight hubs including Oslo Havn, Bergen Port, Brevik, and Larvik with complete customs documentation ready for local installation site distribution.
For installations within 5 kilometers of ocean water, we mandate our Qualanod Coastal Class 25µm Hard Anodized finish or 3-coat PVDF fluorocarbon paint system. This offers certified resistance against C5-M marine atmospheric corrosion, preventing micro-pitting and surface degradation under coastal salt spray exposure.
Purchasing direct from our precision manufacturing facility eliminates intermediary agent markups, providing 30% to 50% cost savings on major commercial fenestration packages. Furthermore, you gain direct access to our structural engineering department for custom CAD shop drawings, glass stackup calculations, and expedited lead times.
