Get a QuoteWhy modern architectural developers, general contractors, and trade importers in the Grand Duchy are transitioning to factory-direct aluminum casement profiles.
The Grand Duchy of Luxembourg represents one of Europe's most demanding fenestration markets. Driven by stringent national energy performance directives (such as the Energiepass and LENOZ sustainability certifications), real estate developments across Luxembourg City, Kirchberg, Belval, and Esch-sur-Alzette require window systems that go far beyond basic aesthetics. The region's transitional oceanic-continental climate—characterized by freezing winter humidity, driving summer rain, and frequent thermal cycling—demands profiles that eliminate thermal bridging entirely.
Historically dominated by heavy uPVC or maintenance-intensive timber frames, the Luxembourg architectural sector has shifted decisively toward thermally broken 6063-T5 aluminum casement systems. Aluminum offers structural integrity capable of supporting triple-glazed acoustic glass assemblies weighing over 120 kg per sash, while maintaining slim, elegant sightlines that maximize solar heat gain during winter months.
Our manufacturing facility serves as a direct engineering partner for Luxembourg contractors, supplying fully customized, CE-compliant casement windows that fulfill Klimabonus tax credit subsidies (requiring whole-window U-values $U_w \le 0.90 \text{ W/m}^2\text{K}$). By manufacturing in-house with German-engineered hardware and polyamide thermal breaks, we deliver European-tier performance at direct factory pricing.
A granular look at the raw materials, extrusion physics, and locking mechanisms built into every casement frame.
Our profile frames are extruded exclusively from primary 6063-T5 magnesium-silicon aluminum alloy. T5 artificial aging treatment ensures a tensile strength $\ge 185 \text{ MPa}$ and yield strength $\ge 110 \text{ MPa}$. This structural rigidity allows ultra-slim sightlines that resist severe atmospheric wind loads (EN 12210 Class C5) without frame deflection.
Monolithic metal frames conduct extreme winter cold into interior spaces. We mechanically crimp 24mm to 34mm PA66GF25 (Polyamide 66 reinforced with 25% glass fiber) thermal break strips between interior and exterior aluminum profiles. This interrupts thermal conduction, keeping interior frame temperatures comfortable and preventing condensation.
Every opening sash is equipped with high-grade European hardware (Siegenia, GU, or Roto gear mechanisms). Featuring mushroom-head locking cams, heavy-duty concealed friction hinges, and anti-slam stays, our casement sashes achieve DIN EN 1627 RC2/RC3 forced-entry protection and smooth operation for over 50,000 opening cycles.

Customizing structural engineering to meet the precise architectural demands of Luxembourg’s distinct cantons.
High-rise residential towers and modern corporate offices near the Luxtram lines demand extreme acoustic damping ($R_w \ge 45\text{ dB}$) to isolate urban traffic rumble. Our soundproof casement series uses acoustic laminated glass interlayers with multi-density EPDM compression gaskets to ensure silent interior environments.
New sustainable residential developments in southern Luxembourg mandate ultra-low operational carbon footprints. Our Passive-75 casements integrate warm-edge composite spacers and argon-filled triple glazing to exceed municipal thermal performance criteria, helping developers qualify for eco-subsidies.
Properties in northern Luxembourg face elevated wind exposures and severe winter frost. Our heavy-duty awning and French casement profiles feature Qualicoat Class 2 powder coating (resisting UV radiation and frost oxidation) and multi-point perimeter compression seals tested against driving rain up to 1050 Pa.
Key technical innovations driving procurement decisions among European developers and architects.
Homeowners and commercial property owners in Luxembourg increasingly prioritize physical security. Modern factory casements now integrate internal steel corner keys, anti-drill lock plates, and toughened laminated glazing to withstand mechanical break-in tools, meeting official EU security mandates without unsightly bars.
With summer temperatures rising across Western Europe, overheating in glass-heavy structures has become a major concern. Luxembourg specifiers prefer double Low-E soft coatings paired with solar-control tinting ($g\text{-value} \approx 0.35$ to $0.42$), allowing natural light while reflecting radiant solar heat.
Visual minimalism dominates Luxembourg interior design. European buyers favor flush casement sashes that sit entirely parallel with the outer frame. Concealed hinges eliminate visible metal barrels, providing sleek, clean sightlines that harmonize with minimalist modern architecture.
Bridging direct factory fabrication with rigorous quality control, custom engineering, and consolidated export logistics.
With over 30 years of manufacturing experience, our production line operates on full CNC automated cutting, corner-crimping, and milling machinery. Unlike localized assembly workshops or brokers, we extrude high-purity 6063-T5 aluminum profiles and bond polyamide thermal breaks under strict factory-controlled tolerances.
This integrated supply chain allows us to maintain strict quality control across every window unit, guaranteeing structural durability, zero frame leakage, and perfect finish consistency across large-volume commercial shipments.
We streamline shipping for Luxembourg general contractors, dealers, and project managers. Entry-tier vinyl and standard stock units ship within 2 to 4 weeks. Custom thermally broken aluminum casements, heavy architectural sliding doors, and specialized acoustic glass make-ups ship in 4 to 8 weeks.
Every shipment is packaged in ISPM-15 compliant sea-freight crates with waterproof vacuum wraps, customized shop drawings, detailed installation schematics, and full CE / NFRC performance documentation for hassle-free customs clearance.
Technical answers to common questions asked by architects, importers, and project engineers.
Yes. Luxembourg’s Klimabonus scheme requires replacement windows to achieve a overall U-value ($U_w$) of $0.90 \text{ W/m}^2\text{K}$ or lower. Our Passive-75 and Thermal Break Triple-Glazed Casement series achieve certified $U_w$ ratings down to $0.78 \text{ W/m}^2\text{K}$, fully qualifying your project for state subsidies.
We extrude frames using high-grade 6063-T5 architectural aluminum. The thermal barrier consists of high-density PA66GF25 (polyamide 66 with 25% glass fiber reinforcement). This structural break interrupts metal heat conduction, preventing surface condensation during cold winter mornings in Benelux climates.
Absolutely. We provide full Qualicoat powder coating, anodizing, and wood-grain thermal transfer finishes. Dual-color processing is standard: you can specify dark anthracite (RAL 7016) for the exterior face to match regional facade trends, while choosing pure white (RAL 9016) or anodized bronze for interior frames.
Our casement frames feature multi-stage EPDM weather-stripping gaskets, concealed drainage channels with non-return flap valves, and continuous corner vulcanization. Tested to European EN 12208 standards, our casements withstand water pressures up to 1050 Pa (Class E1050).
Standard profile production takes 2 to 4 weeks, while custom thermal break casement orders take 4 to 8 weeks. Products are shipped in fumigated, steel-reinforced wooden crates with corner protectors and moisture-proof plastic film to ensure damage-free transit directly to project sites in Luxembourg.
All window frames, powder coat finishes, and glass units come backed by our comprehensive factory warranty (10 years on extrusions & glass seals, 5 years on hardware). We provide shop drawings, BIM models, installation guides, and spare parts support directly from our engineering team.
Send us your window schedules, architectural elevations, or opening dimensions. Our fenestration engineers will provide shop drawings, thermal calculations, and direct factory pricing within 24 hours.
