Custom-engineered architectural profiles built from 6063-T6 aluminum alloy with sigma-welded joints, designed to surpass European U-value thermal standards and withstand maritime climate exposure.
Belgium’s building construction sector operates under stringent environmental performance standards governed by regional authorities: the Flemish Energy and Climate Agency (VEKA) in Flanders, the Service Public de Wallonie (SPW) in Wallonia, and Brussels Environment (IBGE). Under the current Energieprestatie en Binnenklimaat (EPB) frameworks, double glazing and window frame assemblies imported for residential or commercial projects must meet exacting thermal transmittances (U-values) and airtightness metrics to achieve compliance.
For Belgian architectural projects, standard double glazing unit (DGU) specifications typically require an Ug-value of ≤ 1.0 W/m²K, achieved via a combination of soft-coat Low-E (Low Emissivity) coatings, argon gas filling (90%+ concentration), and warm-edge composite spacer bars (such as Technoform or Swisspacer). When integrated into our heavy-duty 6063-T6 extruded aluminum profiles with multi-chamber polyamide (PA66 GF25) thermal barriers, our complete window assemblies deliver an overall Uw-value ranging between 0.85 W/m²K and 1.3 W/m²K—fully aligned with Belgian RENOVATION 2050 targets and BEN (Bijna-Energieneutraal / NZEB) building codes.
From coastal marine conditions along the North Sea to historic urban centers in Ghent and Brussels, our custom double glazing and thermal break aluminum windows are engineered for specialized regional demands.
Fenestration in West Flanders must withstand extreme saltwater corrosion, high ambient moisture, and gusting wind pressures exceeding 1600 Pa (Class C5 wind load resistance). Our 6063-T6 aluminum frames receive Qualicoat Seaside certified powder coating and feature 100% continuous sigma-welded joints, eliminating vulnerable screw joints where salt air causes internal oxidation.
Replacing legacy single-glazed steel or timber sashes in historic Belgian townhouses demands ultra-slim profile sightlines without sacrificing modern thermal performance. Our thin-profile architectural casement and tilt-and-turn series replicate heritage aesthetics while integrating 28mm double glazed low-E units for superior energy retention.
Urban acoustic pollution along major ring roads (R0 in Brussels, R1 in Antwerp) requires specialized soundproof double and triple glazing packages. By utilizing asymmetric glass thicknesses (e.g., 6mm toughened outer + 16mm argon gap + 4.4.2 acoustic PVB laminated inner), our window systems achieve up to 45 dB (Rw) sound insulation.
New-build BEN (Nearly Zero Energy Building) residences utilize multi-chamber thermally broken tilt-and-turn (Draaikiep) double and triple-glazed sashes. Micro-ventilation options allow baseline air movement while preventing thermal bridging during cold Ardennes winter nights.

| Thermal Barrier System | 14mm PVC or basic polyamide strips | 24mm to 34mm PA66 GF25 Polyamide Strips | Lowers frame Uf to ≤ 1.4 W/m²K, preventing interior sweating |
| Glazing Seal & Gaskets | Standard PVC gaskets | Triple EPDM Weatherstripping Seals | Class 4 Air Tightness (EN 12207) under severe storm pressure |
| Hardware Integration | Generic surface-mounted hardware | European Groove / Siegenia / Sobinco Tilt-Turn | Smooth multi-point locking (RC2/RC3 burglar resistance certified) |
| Surface Finish Standard | Standard 60-micron powder coating | Qualicoat Seaside / PVDF 80-micron Finish | Resists severe saline mist in coastal Flemish regions |
Building double glazed aluminum sashes for international export requires absolute precision. Unlike mass-market suppliers offering rigid stock sizes that force builders to use unsightly gap fillers, every single unit from our factory is fabricated strictly according to your submittal shop drawings.
Every frame member, sash, and door panel joint is fused solid via high-precision welding, then hand-dressed smooth for a flawless paint finish that outlasts mechanical joints.
Our engineering office prepares CAD elevations and cross-section details for every opening, allowing Belgian architects to verify glass bite, rough opening dimensions, and egress compliance before production.
Windows are protective-wrapped, corner-shielded, and packed into ISPM-15 compliant sea-freight wooden crates destined directly for Port of Antwerp-Bruges or Zeebrugge.
Understanding shifting procurement dynamics for Belgian window importers, trade distributors, and general building contractors.
Belgian end-users heavily prefer dual-action tilt-and-turn windows. The tilt mode provides safe, rainproof background ventilation during wet Flemish spring days, while the turn mode allows easy cleaning of exterior glass panes from inside high-rise apartments.
Modern Belgian residential designs favor dark textured exterior finishes (RAL 7016 Anthracite Grey, RAL 9005 Jet Black) paired with dual-color anodizing options to match contemporary brickwork facades.
Belgian public tenders increasingly request Environmental Product Declarations (EPDs). Aluminum's 100% recyclability and long service life make our 6063-T6 frames a preferred sustainable material choice over short-lifecycle vinyl (uPVC).
