How advanced extrusion engineering and polyamide isolators eliminate thermal bridging in extreme alpine environments.
Switzerland presents one of the most demanding built-environment landscapes in Europe. With winter ambient temperatures dropping below -20°C in high-altitude cantons like Valais, Graubünden, and Bernese Oberland, while summer temperatures exceed +30°C in urban hubs like Zurich and Geneva, architectural fenestration faces severe thermal stress. Standard non-insulated aluminum profiles exhibit high thermal conductivity ($\lambda \approx 200 \text{ W/m}\cdot\text{K}$), leading to massive interior heating loss, surface condensation, structural frost heave, and mold growth.
As a specialized thermal break extrusion factory and strategic B2B supplier to the Swiss market, our systems incorporate high-precision Polyamide 66 reinforced with 25% structural glass fiber (PA66-GF25) thermal barrier strips. Polyamide 66 features an exceptionally low thermal conductivity ($\lambda \approx 0.3 \text{ W/m}\cdot\text{K}$), effectively separating the outer aluminum profile facing harsh atmospheric exposure from the interior profile maintaining indoor climate control.
Key Engineering Metric: By combining multi-cavity PA66-GF25 thermal isolators with high-grade 6063-T6 architectural alloy profiles, our thermal break assemblies achieve window frame thermal transmittance values ($U_f$) ranging from 0.8 to 1.3 W/m²K, meeting and exceeding Swiss Minergie-P and SIA 380/1 energy targets.
| Performance / Spec Metric | Standard Aluminum Extrusion | Swiss-Grade Thermal Break System (HAQ) | Swiss Regulatory Standard (SIA / Minergie) |
|---|---|---|---|
| Thermal Transmittance ($U_f$) | 5.8 – 7.0 W/m²K | 0.8 – 1.2 W/m²K | Must be ≤ 1.3 W/m²K for energy subsidies |
| Isolator Material | None / Basic PVC strips | PA66-GF25 (Polyamide + 25% Glass Fiber) | SIA 271 high structural shear resistance |
| Thermal Expansion Coeff. ($\alpha$) | $23 \times 10^{-6} /\text{K}$ (Aluminum) | Matched PA66-GF25 ($24 \times 10^{-6} /\text{K}$) | Prevents seal shearing under $\Delta T = 60\text{K}$ |
| Alloy & Temper Options | Commercial 6063-T5 | Precision 6063-T6 / 6061-T6 / 6082-T6 | EN 755-2 structural alloy compliance |
| Acoustic Insulation ($R_w$) | 22 – 28 dB | 42 – 48 dB (with acoustic glazing) | SIA 181 noise abatement compliance |
| Surface Protection | Mill Finish / Standard Anodized | Qualicoat Class 2 / Qualanod 25μm | High resistance to alpine frost & salt spray |
Customized thermal break extrusion profiles optimized for diverse architectural and climate requirements in Zurich, Geneva, Ticino, and Alpine regions.

Tailored for Switzerland's world-leading pharmaceutical and biotechnology campuses in Basel and Zug. Airtight thermally broken frames prevent moisture ingress, maintain strict pressure differentials, and allow easy surface sterilization.
Combining extruded thermal break framing with Building-Integrated Photovoltaic (BIPV) mountings. Supports Switzerland's energy transition goals (Energy Strategy 2050) by generating renewable solar power while sealing exterior facades.
Extruded high-density thermal management profiles for Swiss electronic machinery, railway traction systems (SBB CFF FFS), and medical diagnostic equipment requiring optimal heat dissipation.
The Cantonal Energy Directors' Conference (EnDK) has tightened energy regulations across all 26 cantons. Modern Swiss building codes prohibit uninsulated metal frames in envelope construction. Building owners and general contractors must verify heat transfer coefficients before obtaining building permits, boosting the demand for factory-certified thermal break extrusion suppliers.
Swiss developers prioritize Environmental Product Declarations (EPD) and BREEAM/LEED certification. Our production facility uses high-purity recycled aluminum billet scrap and hydroelectric power sourcing, significantly reducing embodied carbon per kilogram of extruded profile compared to global industry averages.
Contemporary Swiss design emphasizes maximum natural daylight with ultra-slim structural frames. Achieving mechanical stiffness with minimal visible profile widths requires high-yield alloys like 6063-T6 and 6061-T6 combined with structurally bonded polyamide thermal breaks.
Given the harsh climate variability in northern and alpine Switzerland, architects specify super-durable architectural powder coatings (Qualicoat Class 2) or heavy anodizing (25 microns). Our in-house electrostatic powder coating line ensures 20+ years of color retention and chalking resistance.
With a metallurgical lineage dating back to 1972, HAQ Aluminium combines half a century of metal processing expertise with modern European extrusion technology. Our manufacturing campus in Lahore houses billet pre-heating, multi-ton hydraulic extrusion presses, precision aging ovens, automated thermal break insertion lines, and electrostatic powder coating under a single roof.
Technical, regulatory, and logistics answers for Swiss architectural fabricators, facade engineers, and purchasing managers.
Our thermal break extrusions incorporate multi-chamber PA66-GF25 polyamide thermal insulation strips ranging from 14.8mm to 34mm in width. When assembled with thermal foam inserts and triple glazing, frame thermal transmittance ($U_f$) values drop as low as 0.8 W/m²K. We provide detailed finite element thermal calculation reports (in accordance with EN ISO 10077-2) to support your building permit applications across Swiss cantons.
For standard architectural windows and door systems, we extrude high-surface-finish 6063-T5 and 6063-T6 billets. For high-rise curtain walls, structural mullions, and heavy wind-load applications in Alpine regions, we extrude structural 6061-T6 and 6082-T6 alloys offering significantly higher tensile and yield strength.
Yes. You can supply CAD drawings in DXF or STEP format, or send a physical profile section. Our tooling engineering team analyzes circumscribing circle diameter, press tonnage requirements, and thermal strip insertion slots. We sink the custom die, produce first-article samples within 10 to 15 working days, and send full dimensional inspection reports for your written sign-off before mass extrusion.
We operate an in-house chromate-free pre-treatment line and an automated electrostatic powder coating system using Qualicoat Class 2 super-durable architectural polyester powders (RAL colors, metallic finishes, and textured wood-grain sublimation). We also offer anodized finishes (Natural, Bronze, Black, Gold) certified up to 25 microns (Qualanod grade) for exceptional salt and UV resistance.
Our standard MOQ for custom architectural extrusion dies is 500 kg to 1,000 kg per profile section depending on size. Standard production lead time is 2 to 3 weeks post sample approval. Sea freight shipping to European container ports (Rotterdam, Hamburg, or Genoa) followed by customs clearance and truck dispatch to Swiss destinations (Zurich, Basel, Geneva) typically takes 25 to 35 days.
Every extruded profile is interleaved with protective PE film or tissue paper. Profiles are then wrapped in shrink foil, bundled, corner-protected, and packed into steel-strapped wooden crates or heavy-duty wooden skids designed for safe container loading and unloading by fork trucks at your Swiss warehouse.
Our engineering desk reviews CAD drawings, alloy specifications, surface requirements, and Swiss project schedules within 24 hours.
