Technical Whitepaper
Engineering Aluminium-Clad Wood Windows for the Swiss Built Environment
Switzerland presents one of the world's most demanding regulatory and microclimatic ecosystems for building envelopes. From the perennially frosty Alpine altitudes of Graubünden and Valais to the dense urban landscapes of Zurich, Geneva, and Basel, fenestration products must satisfy stringent cantonal building mandates. Derchi's aluminium and wood window systems bridge architectural warmth with exterior durability by pairing European-sourced FSC-certified interior timber with exterior marine-grade, powder-coated aluminium shells.
In accordance with SIA 331 (Fenster und Fenstertüren) and SIA 380/1 (Thermische Energie im Hochbau), our bespoke hybrid profiles incorporate multi-chamber PA66 GF25 thermal breaks that decouple structural conductive paths. This structural configuration isolates the interior timber sash—available in sustainably harvested Larch, European Oak, or Alpine Spruce—from external moisture cycles while preserving its cellular insulation capabilities.
| Performance Characteristic | Swiss Regulatory Benchmark (SIA / Minergie) | Derchi High-Spec Technical Delivery | Test Methodology |
|---|---|---|---|
| Overall Heat Transfer (Uw) | Standard: ≤ 1.0 W/(m²K) | Minergie-P: ≤ 0.80 W/(m²K) | Uw up to 0.76 W/(m²K) (Triple Low-E, Argon 90%, Warm-Edge) | EN ISO 10077-1 / EN ISO 10077-2 |
| Air Permeability | Class 4 (Standard SIA 331 / EN 12207) | Class 4 (Continuous Co-extruded EPDM gaskets, 3 tiers) | EN 1026 / EN 12207 |
| Water Tightness | Class E900 or Higher (High-Altitude Driving Rain) | Class E1200 (Concealed Sub-sill Multi-Cavity Drainage) | EN 1027 / EN 12208 |
| Sound Insulation (Rw) | SIA 181 Norm: Rw + Ctr ≥ 35 dB to 42 dB near arteries | Rw up to 45 dB with asymmetric acoustic laminated glazing | EN ISO 717-1 / EN ISO 10140 |
| Burglary Resistance | RC2 / RC3 (Swiss Police & Cantonal Insurance Recommendations) | RC2 / RC3 configuration: Mushroom pins, hardened steel keeps | EN 1627 - EN 1630 |
Our surface finishing procedures utilize multi-layer waterborne, microporous natural oil finishes on timber layers to eliminate indoor volatile organic compound (VOC) emissions, fully aligning with Swiss eco-construction benchmarks (SNBS). On the exterior aluminium cladding, fluorocarbon (PVDF) or Qualicoat Class 2 architectural powder coatings shield against high UV indexes at mountain elevations, eliminating routine exterior repainting.
Regional Applicability
Tailored Fenestration Solutions Across Swiss Regions
Whether designing contemporary urban residential villas or restoring traditional Alpine chalets, our bespoke manufacturing capabilities accommodate specific cantonal and topographic demands.
Alpine Chalets & Ski Lodges (Valais, Engadin, Bernese Oberland)
Extreme temperature shifts require robust thermal stability. Derchi's aluminium-clad timber systems combine structural larch or spruce framing with external anodized aluminium, preventing moisture freeze-thaw cracking and providing exceptional snow-load and wind-pressure resistance.
Thermal: Uw ≤ 0.78 W/(m²K) · Snow Load Class 5
Urban Low-Energy Residences (Zurich, Geneva, Basel)
Urban architecture demands superior acoustic insulation alongside strict Minergie energy efficiency. With multi-point peripheral hardware and acoustic PVB glass sandwiches, our tilt-and-turn windows isolate tram and arterial transit noise while preserving sleek sightlines.
Acoustic: Rw 42-45 dB · RC2/RC3 Security
Panoramic Lakefront Estates (Lake Geneva, Lugano, Lucerne)
Maximizing water views necessitates large structural openings. Our minimalist heavy-duty lift-and-slide doors and oversized panoramic bi-fold systems deliver thermal efficiency while maintaining structural integrity against lake squalls and driving rains.
Watertightness: Class E1200 · Minimalist Sightlines
Market Evolution
Emerging Fenestration Trends in the Swiss Construction Sector
Insight into how architectural requirements, regulatory developments, and environmental commitments are shaping window procurement throughout Switzerland.
1. Embodied Carbon & Circularity (SIA 2039)
Swiss cantons increasingly evaluate construction products through full Life Cycle Assessments (LCA). Aluminium-wood composite assemblies with mechanically separated components allow 100% material recycling at end-of-life, reducing lifetime carbon footprints compared to PVC alternatives.
2. Concealed Minimalist Hardware
Contemporary Swiss architectural aesthetics favor fully concealed hinges, clean rebates, and zero-threshold sliding sills. Flush transitions between interior parquet floors and exterior granite terraces must maintain continuous drainage without compromising airtightness.
3. Smart Home & Building Automation
Automated micro-ventilation, motorized locking mechanisms, and integrated reed contact sensors (VdS certified) for smart burglar alarm connectivity are rapidly becoming standard specifications for high-end residential projects in Geneva, Zug, and Zurich.
Procurement Knowledge Base
Frequently Asked Questions by Swiss Buyers & Developers
Transparent technical answers regarding SIA compliance, customs clearance into non-EU Switzerland, logistics handling, and on-site engineering verification.
Do your aluminium and wood windows comply with Swiss SIA standards and Minergie energy ratings?
Yes. Our window systems are engineered to achieve overall thermal insulation values (Uw) down to 0.76 W/(m²K), matching the requirements of SIA 380/1 and Minergie-P standards. Profiles are equipped with multi-chamber polyamide thermal breaks, argon-filled triple-glazed units with warm-edge spacers, and multi-tier EPDM sealing systems compliant with SIA 331 specifications for air permeability and driving rain resistance. Complete factory testing data sheets and calculation certificates can be supplied for your local cantonal building authorization filing.
How do you manage customs clearance, Tares tariffs, and logistics into non-EU Switzerland?
Because Switzerland is outside the European Union customs area, all shipments require specific documentation under Swiss Tares customs tariff codes. We offer DDP (Delivered Duty Paid) or CIF (via major entry points including Basel Rheinhafen or direct inland multimodal rail/truck depots). We provide accurate EUR.1 / Origin documentation, commercial invoices indicating net weights for precise Swiss weight-based tariff calculations, and full packing declarations. Units are packaged in heavy-duty fumigated steel-reinforced wooden crates designed to navigate Alpine transit routes safely.
What hardware brands and surface finishes do you incorporate into your bespoke windows?
We partner with premier European hardware manufacturers including Siegenia, Roto, and HOPPE to ensure long-term reliability and straightforward on-site adjustment or replacement by local Swiss carpenters. For wood surfaces, we apply environmentally friendly, low-VOC Remmers or Sikkens waterborne primers and microporous sealers. Exterior aluminium frames receive Qualicoat Class 2 architectural powder coating or deep anodizing (20-25 microns) to resist high solar radiation, altitude weathering, and salt exposure along lakeside microclimates.
Can you support custom architectural drawings and BIM integration for Swiss engineering practices?
Yes. Our in-house technical engineering division works directly with your architectural drafts. We provide DWG/DXF shop drawings, 3D section details, structural load calculations (wind pressure and glass deflection), and Revit/IFC BIM family files. We review connection details (Bauanschluss) with your project manager to ensure thermal bridge mitigation around reveals and sills, fully adhering to the Swiss "Empfehlungen zur Ausführung von Fensteranschlüssen" guidelines.
How are warranty, technical claims, and glass replacements handled remotely in Switzerland?
We back our aluminium-clad timber fenestration products with a comprehensive 10-year warranty on structural profile integrity, extrusion coatings, and hermetic glass sealings, alongside a 5-year warranty on moving hardware components. Should a verified warranty defect occur, replacement hardware or glazing bead assemblies are expedited via express international courier. We maintain detailed digital production twins of every manufactured unit, enabling our engineering team to mill and reproduce exact sash components using the original CAD record.
