Technical Engineering Insight
Acoustic Fenestration Engineering: Meeting Norway's NS 8175 & TEK17 Demands
In Norway's rapidly densifying cities—such as Oslo, Bergen, Stavanger, and Trondheim—building envelopes face simultaneous acoustic and thermal stresses. The Norwegian technical standard Byggteknisk forskrift (TEK17) mandates strict overall heat transfer coefficients (U-values) alongside acoustic insulation limits governed by NS 8175 (Acoustic conditions in buildings - Sound classification of various types of buildings). Achieving an interior sound class B or C environment against low-frequency electric light-rail transit, coastal maritime shipping, and gusting Atlantic wind noise requires far more than merely installing double or triple glass.
Standard symmetric glazing assemblies often fail in low-to-mid acoustic frequencies due to internal coincidence frequency dip phenomena. To solve this, our engineering department designs asymmetric acoustic laminated glass mockups featuring multi-layer polyvinyl butyral (PVB) acoustic interlayers (e.g., 8mm Toughened Outer + 16mm 90% Argon Cavity + 44.2 Acoustic PVB Inner). When coupled with our structural polyamide thermal breaks (PA66 GF25), the profile breaks both thermal bridges and structural sound wave transmission through the fenestration frame.
| Glazing Specification (Acoustic Build-up) | Sound Reduction Index (Rw dB) | Traffic Damping (Rw + Ctr dB) | Thermal U-value (W/m²K) | Recommended Norwegian Application |
|---|---|---|---|---|
| 6mm Low-E + 16Ar + 4mm Float | 35 dB | 30 dB | 1.10 | Low-traffic Suburban Cabins (Hytter) |
| 8mm Float + 16Ar + 6mm Toughened | 38 dB | 33 dB | 1.05 | Regional Town Centers & School Classrooms |
| 8.76mm Acoustic PVB + 16Ar + 6mm Float | 42 dB | 37 dB | 0.95 | Oslo Ring 2/Ring 3 Perimeter Apartments |
| 10.76mm Sound PVB + 18Ar + 8.76mm Sound PVB | 47 dB | 42 dB | 0.82 | Harbor Front, Rail Corridors & Heliport Zones |
| Triple Glazed 12.76Acoustic + 14Ar + 6 + 14Ar + 8.76Acoustic | 50 dB | 44 dB | 0.74 | NS 8175 Class A Ultra-Acoustic Passive Envelopes |
Furthermore, air permeability is paramount in acoustic preservation. Under EN 12207 Class 4 and EN 12208 Class E1200 testing metrics, our soundproof casement and tilt-and-turn series utilize seamless, continuous EPDM co-extruded triple gaskets. This eliminates micro-gaps through which high-frequency sound and coastal gale-force water infiltration can penetrate.
Project Architecture
Engineered For Distinctive Nordic Applications
Our soundproof and thermally insulated aluminium systems provide custom exterior solutions across key demographic and geographical segments throughout Norway.
Urban Dense Redevelopments (Oslo & Trondheim)
High-density multi-family residential towers positioned directly adjacent to tramlines, passenger railways, and city expressways require NS 8175 Sound Class C compliance. Our tilt-and-turn configurations deliver secure indoor micro-ventilation with continuous compression gaskets that shut out road noise up to 45 dB.
Engineered with high-tensile 6063-T6 frames, they accommodate massive sound-attenuating triple-pane IGU packages without hinge sagging or frame deflection over decades.
Coastal Fjord Villas & Commercial Harbors
The Norwegian western shoreline (Bergen, Ålesund, Stavanger) experiences severe Atlantic wind-driven rainfall and corrosive maritime salt spray. Conventional timber-clad windows suffer exterior degradation and water ingress under gale-force barometric pressure.
Our marine-grade anodized and Qualicoat Seaside-certified powder-coated frames withstand C5-M extreme marine corrosive classifications, keeping coastal villas silent during intense North Sea storms.
Nordic Hospitality & High-End Cabins (Hytter)
Mountain lodges and wilderness boutique hotels across Hemsedal, Trysil, and Lofoten demand floor-to-ceiling panoramic glass vistas coupled with absolute acoustic silence and passive-level thermal retention.
We fabricate oversized bi-folding and heavy-duty lift-and-slide patio doors equipped with multi-chamber polyamides, providing unbroken views of the aurora borealis while keeping biting -30°C winter sub-arctic temperatures outside.
Industry Horizon
Market Evolution & Sustainable Architecture in Norway
Understanding why general contractors, façade specifiers, and civil engineers in Norway are shifting from traditional timber to performance-machined aluminium.
Low-Carbon Aluminium (Circal / Hydro 75R Equivalence)
BREEAM-NOR certification is now standard for Tier-1 Norwegian commercial and multi-family tenders. Developers actively prioritize low-carbon aluminium extrusions refined using renewable hydroelectric energy.
Our supply chain integrates high-percentage post-consumer recycled billets, supplying verified Environmental Product Declarations (EPD) that contribute directly to achieving BREEAM-NOR 'Outstanding' and 'Excellent' ratings.
Transition from Timber-Alu to Structural All-Aluminium
For decades, the Nordic market relied on Scandinavian timber with exterior aluminium cladding (tre-alu). However, recurring issues with interstitial condensation rotting hidden wood cores have led engineering firms to shift toward full thermal-break aluminium systems.
Engineered aluminium will not warp, twist, or rot, allowing significantly slimmer sightlines and supporting modern architectural trends for heavy, sound-damped multi-laminated glass weights up to 600 kg per panel.
Stringent Airtightness & Low-Frequency Traffic Isolation
With the rapid adoption of electric vehicles in Norway, high-frequency combustion engine whine has subsided, making low-frequency tire rumbling and road vibrations more noticeable inside residential master bedrooms.
Norwegian acoustic consultants specifically seek window assemblies with high Ctr coefficients (traffic noise attenuation index). Our custom multi-cavity chamber design is optimized specifically for low-frequency vibration absorption.

Buyer Knowledge Base
Frequently Asked Questions by Norwegian Buyers
Clear technical, logistic, and regulatory answers for developers, builders, and distributors sourcing aluminium window systems for Norway.
Q
How do your aluminium systems satisfy Norwegian TEK17 thermal regulations?
TEK17 states an overall requirement where windows must achieve an average U-value of ≤ 1.2 W/m²K, with high-performance specs often targeted at ≤ 0.80 W/m²K. We achieve these rigorous targets by pairing wide polyamide insulating strips (PA66 GF25 up to 34mm) with warm-edge composite spacers and argon-filled triple-glazing with two low-emissivity coatings, achieving certified Uw values down to 0.78 W/m²K.
Q
What acoustic test certifications accompany your export shipments to Norway?
Our window and door lines are factory and lab-tested in accordance with EN ISO 10140-2 and rated under EN ISO 717-1 for sound insulation metrics (Rw, C, and Ctr). Full accredited third-party acoustic performance certificates, showing test curves from 100 Hz to 5000 Hz, are delivered with your project documentation for local municipality (kommune) building control sign-offs.
Q
How do you protect aluminium finishes against high salinity along the Norwegian coastline?
For coastal installations such as Bergen, Kristiansand, and Stavanger, standard polyester powder coating is insufficient. We offer Qualicoat Seaside-class pre-treatment and architectural fluorocarbon (PVDF) finishes, or thick anodizing (up to 25 microns Class AA25). This ensures optimal resistance to C5-M marine atmospheric corrosion, blistering, and UV exposure.
Q
Can we order custom hardware compatible with local Scandinavian locking standards?
Yes. While we supply high-performance multi-point European groove hardware (Roto, Siegenia, or our proprietary zinc alloy heavy-duty hardware), we also machine our aluminium sash profiles to accept standard Scandinavian profile cylinders (such as TrioVing / ASSA Abloy standards), enabling uniform access master-key systems across your property.
Q
What are the lead times and shipping routes for containerized orders to Norway?
Following CAD shop-drawing and finish approval, manufacturing averages 4 to 6 weeks depending on volume. Sea freight routes direct from production ship to major Norwegian ports including Oslo Havn, Bergen Havn, and Brevik, typically taking 30 to 38 days at sea. All customs export clearances, ISPM-15 heat-treated crating, and bill of lading transfers are managed seamlessly.
Q
Do you supply factory glazing or frames unglazed for on-site local installation?
We offer both solutions. For maximum quality assurance and certified acoustic values, fully factory-assembled, glazed, and pressure-tested units are preferred. However, for oversized facade openings or curtain wall units where crane capacities or steep topography in Norwegian fjords dictate, we supply pre-crimped frame kits along with precision glazing beads for on-site glass insertion.
