Engineered for severe climatic variations, high elevation pressure shifts, and low-emissivity energy standards across Switzerland and the Alpine region.
Switzerland's topography presents extreme thermal dynamics—from sub-zero temperatures in the Engadin and Valais Alps to dense urban noise corridors in Zurich, Geneva, and Basel. Our custom triple-glazed fenestration systems are tailored to resolve these specific regional engineering challenges.
At elevations above 1,500 meters, fenestration units endure severe freeze-thaw cycles, high wind loads, intense solar ultraviolet irradiation, and dramatic atmospheric barometric pressure drops. Our high-altitude OEM triple-glazed units utilize capillary capillary equalize valves (pressure compensation tubes) to prevent IGU deflection and seal failure. Combined with high-performance warm-edge spacers (Swisspacer Ultimate) and low-E triple coatings, our windows maintain an exceptional overall U-value ($U_w \le 0.75 \text{ W/m}^2\text{K}$), eliminating interior radiant cold drops.
Swiss urban building regulations push for carbon neutrality under the Minergie-P and Minergie-A standards. In cities like Zurich, Winterthur, and Geneva, high-density residential complexes demand maximum natural daylight alongside extreme solar thermal regulation. Our ODM triple glazing configurations integrate warm-edge spacer bars with dual-chamber argon gas fills (90%+ gas retention rate) and custom triple-silver coating layers, achieving a Solar Heat Gain Coefficient (SHGC) optimized to prevent summer overheating while retaining passive winter solar gains.
Properties adjacent to major SBB rail corridors or Zurich (Kloten) / EuroAirport flight paths require stringent acoustic isolation (EN ISO 140-3). We manufacture specialized soundproof triple glazing incorporating asymmetrical pane glass thicknesses (e.g., 8mm outer toughened + 6mm center + 10.76mm acoustic PVB laminated inner). This configuration breaks acoustic harmonic resonance, achieving sound transmission loss ratings of up to Rw 46–48 dB without compromising thermal insulation.
Restoring historic Swiss properties in Bern, Lucerne, or Lugano often requires strict adherence to cantonal facade conservation guidelines. Our custom OEM capabilities allow us to extrude ultra-slim profiles, replicate vintage decorative muntin grills, and craft classic arch/trapezoid geometry while retrofitting advanced thermal-break aluminum or multi-chamber vinyl frames equipped with high-efficiency triple glazing.
The Swiss construction sector operates under some of the most rigorous thermal efficiency guidelines in the world. Key regulatory frameworks like MuKEn 2014 / 2024 (Mustervorschriften der Kantone im Energiebereich) and the SIA 380/1 standard ("Thermal Energy in Building Construction") dictate that replacement windows and new structures drastically cut transmission heat losses ($H_T$).
Double glazing ($U_g \approx 1.1 \text{ W/m}^2\text{K}$) is rapidly being phased out across Switzerland. Cantonal subsidies (Das Gebäudeprogramm) strongly favor or mandate triple insulated glass units ($U_g \le 0.6 \text{ W/m}^2\text{K}$) for all energy-efficiency retrofits.
Because Swiss buildings are extremely airtight, moisture control is crucial. Our tilt-and-turn and combination hopper windows integrate continuous trickle ventilation channels and multi-stage night vent positions to prevent humidity buildup and mold without thermal leakage.
Swiss architects increasingly audit the full life-cycle assessment (LCA) of building envelope materials. We utilize 100% virgin vinyl profiles free of heavy metals (lead-stabilized vinyl is strictly excluded) and thermal break aluminum alloys produced using clean energy.

Unlike trading companies or localized assembly shops, we own the full vertical fabrication stack—from raw vinyl profile extrusion and thermal-break aluminum milling to insulating glass unit (IGU) assembly and robotically automated fusion welding.
We manufacture frames tailored to exact millimeter dimensions. Whether your schedule calls for standard tilt-and-turn windows, crank casements, or custom trapezoidal clerestories, our automated CNC cutting lines ensure frame squareness within ±0.5mm tolerances.
Our vinyl fenestration series features 4-point simultaneous heat fusion welding. Corners are fused into a monolithic structural frame—eliminating mechanical screws, leaky gasket corners, or sealant degradation across decades of alpine weather exposure.
We operate automated insulating glass production lines equipped with dual Low-E coaters, automated spacer bending, continuous butyl primary sealing, and online argon gas measurement tools (EN 1279-2/3 certified).
To ensure complete compatibility with Swiss architectural expectations, our ODM lines seamlessly integrate authentic Siegenia, Roto Frank, or Hoppe heavy-duty gearboxes, multi-point locking cams, and concealed hinges.
We ship factory-direct to Basel, Zurich, and Geneva hubs. Every unit is shrink-wrapped with protective Corner-Gard padding, placed in fumigated wooden crates, and sequenced by floor plan schedule for fast jobsite distribution.
Every production batch comes accompanied by complete NFRC thermal performance certificates, EN 14351-1 conformity documentation, and structural wind load test reports required by cantonal building authorities.
From CAD blueprint submission to final site delivery in Switzerland—how we streamline cross-border fenestration manufacturing.
Submit your elevation drawings or window schedules. Our engineers analyze wall rough openings, wind load requirements (SIA 261), and thermal compliance specs.
We issue line-by-line shop drawings detailing profile cross-sections, thermal breaks, glass build-up, and hardware locations. Profile samples are dispatched via express courier.
Profiles are extruded, CNC cut, and fusion-welded. Insulating glass units are assembled under strict humidity control, gas-filled, and seal-tested before glazing.
Units are tagged by building floor and opening ID, packed into ocean/rail export crates, and delivered directly to your logistics partner or Swiss jobsite.
Clear, technical answers to common queries regarding standards, logistics, pressure equalization, and custom tooling.
Yes. Our advanced OEM/ODM triple-glazed fenestration systems are specifically designed to meet or exceed Minergie-P requirements. By combining multi-chamber thermal break profiles with 48mm triple insulating glass units ($U_g = 0.5 \text{ W/m}^2\text{K}$) filled with Argon gas and equipped with Swisspacer Ultimate warm-edge spacers, we achieve overall window $U_w$ values as low as 0.72 to 0.78 W/m²K, satisfying SIA 380/1 and cantonal energy codes.
When glass units manufactured at sea level are transported to alpine sites (e.g., St. Moritz at 1,800m or Zermatt at 1,600m), the lower atmospheric pressure causes the trapped gas inside the IGU to expand, leading to glass bowing or seal rupture. For Swiss alpine orders, we equip our triple glazed units with factory-installed capillary tubes (pressure compensation valves). These are sealed at the final jobsite altitude or fitted with micro-porous pressure-equalizing membranes to preserve optical clarity and structural integrity.
Absolutely. As a dedicated OEM/ODM manufacturer, we offer custom die extrusion for aluminum and vinyl profiles. If your project involves replacing historic fenestration in cantonal heritage zones, our engineering team can duplicate existing sightlines, frame depths, and decorative exterior moldings from your physical sample or CAD file.
We standardly offer top-tier European multi-point hardware systems, including Siegenia-Aubi, Roto Frank, and Winkhaus, alongside Hoppe handles. We also offer custom hardware integration if your project specifies particular RC2 / RC3 burglar resistance ratings according to EN 1627 standards.
Fabrication typically requires 15 to 25 days following shop drawing sign-off, depending on order volume and custom finish requirements (e.g., custom RAL anodizing or powder coating). Transit via ocean container to European entry ports (Rotterdam/Hamburg) followed by bonded rail/truck transport to Switzerland generally takes 28 to 35 days. Accelerated air/rail shipping options are available for urgent project phases.
We provide full export documentation under standard Incoterms, including FOB, CFR, CIF, or DDP (Delivered Duty Paid). Our documentation includes HS tariff codes (typically TARIC 3925.20 for vinyl windows or 7610.10 for aluminum units), EUR.1 certificates of origin (where applicable), and complete commercial invoices to facilitate smooth clearance through Swiss Federal Customs Administration (FCA) checkpoints at Basel or Geneva.
We provide a limited lifetime warranty on extruded vinyl and structural aluminum frames, a 10-year warranty against insulated glass unit (IGU) seal failure and desiccant fogging, and a 5-year warranty on mechanical hardware. Replacement parts or glass units are prioritized and dispatched via air freight in the rare event of damage.
