Aluminium exterior door L742 made to order

High-performance aluminium exterior door with 92 mm system depth, ultra-low thermal coefficient Ud 0.85 W/m²K and quadruple Satinato glazing. Premium engineering for contemporary spaces demanding maximum energy efficiency and architectural precision.

Model L742 stands as a reference point in high-performance aluminium exterior doors. The 92 mm total system depth, combined with an 80 mm frame profile and 92 mm leaf thickness, delivers structural stability and clean linear aesthetics that define contemporary aluminium design language. This balanced proportion accommodates both new and retrofit installations without thermal compromise.

Construction integrates 3 mm laminated aluminium with an articulated 34 mm thermal break—an engineered solution that effectively separates exterior-to-interior heat transfer. Quadruple glazing—triplex 44.1 / 5 mm Satinato glass / triplex 44.1—creates a reference-grade acoustic and thermal barrier suited to urban environments and severe climatic exposure. Triple EPDM gasket sealing maintains hermetic closure across the product lifecycle.

Thermal performance certified by ift Rosenheim (Ud 0.85 W/m²K) positions this door among top-tier solutions for high-efficiency building standards. Wind penetration, water penetration, and compression resistance are ift-validated, guaranteeing stable behaviour under extreme conditions. Robust construction and surface treatments ensure long-term durability without performance degradation.

Dimensional flexibility is substantial: standard version up to 1100×2300 mm, single-leaf variant up to 1200×2500 mm, accommodating diverse spatial and architectural proportions. Opening systems—hinges, closers, handles—can be tailored to orientation and usage frequency without affecting structural integrity.

Recommended for modern residences, commercial interiors, office environments and buildings with thermal and acoustic performance requirements. Pairs seamlessly with matching aluminium window systems, creating architectural coherence across façade design. Ideal for passive houses, eco-certified projects, and installations requiring international performance certification standards.

The Ud coefficient of 0.85 W/m²K (ift Rosenheim certified) indicates top-tier thermal insulation — significantly above European standards. This is achieved through the quadruple glazing system and 34 mm articulated thermal break, dramatically reducing heat loss and heating costs. ift testing is the gold standard for premium door performance.

The quadruple system with Satinato (44.1 triplex / 5mm Satinato / 44.1 triplex) combines two laminated glass layers with a central diffusing pane. Satinato provides controlled frosting effect and elegant diffused light while protecting privacy without sacrificing transparency. Four layers deliver exceptional acoustic and thermal insulation.

Standard maximum dimensions are 1100×2300 mm; for a single mobile leaf you can reach up to 1200×2500 mm. This door is available for custom orders to fit non-standard openings — contact us with your frame measurements and our sales team will propose the optimal configuration. The modular aluminum construction allows precise adjustments without performance compromises.

The system has a total depth of 92 mm — frame 80 mm deep and mobile leaf 92 mm. Aluminium profiles are 3 mm thick, ensuring rigidity and lightness. The articulated 34 mm thermal break separates interior from exterior and eliminates direct heat conduction, crucial for exceptional thermal performance. Hybrid aluminium + insulation construction is the standard for premium exterior doors.

The door features 3 EPDM gaskets around the entire perimeter, ensuring multi-point sealing against water, wind, and infiltration. EPDM (synthetic elastomer) is standard in premium exterior applications due to UV resistance and long-term durability. The combination of system depth (92 mm) and triple sealing provides long-term protection even in high-wind or heavy-rain areas.

The modular 92 mm system adapts to standard and new frames, compatible with brick, concrete, or stone masonry. Installation requires professionalism to maintain insulation integrity — polyurethane foam sealing combined with exterior weatherstrips is recommended. Post-installation, access to the closing mechanism allows fine adjustments for perfect closure. Our recommendation: have installation certified by an authorized service to preserve warranties.
