Aluminium exterior door L410 made to order

Premium aluminium entrance door L410 with exceptional thermal insulation (Ud 0.85 W/m²K) and quadruple glazing, delivering superior energy efficiency and lasting durability.

The L410 exterior door is a premium access solution engineered for clients demanding exceptional energy performance. This contemporary aluminium model, crafted with 3 mm profile thickness, integrates seamlessly into modern minimalist façades, creating a refined and understated entrance presence.

The system is built on a total depth of 92 mm with an 80 mm frame and matching leaf dimension, ensuring structural rigidity and long-term stability. The articulated thermal break of 34 mm is the critical element that dramatically reduces heat transfer through the door leaf. Triple EPDM gasket sealing provides comprehensive protection against air and water infiltration, guaranteeing lasting weathertightness and reliability.

The quadruple glazing configuration—44.1 triplex / 5mm Satinato / 44.1 triplex—delivers a thermal coefficient of Ud 0.85 W/m²K, independently verified by ift Rosenheim. This performance aligns with the most stringent European energy efficiency standards. The acoustic insulation is inherently substantial due to the glazing mass and system density, creating a quiet interior environment.

Dimensional flexibility ranges from 1100×2300 mm as standard up to 1200×2500 mm for single-leaf configurations, allowing adaptation to diverse architectural openings without compromise. Installation integrates smoothly with standard aluminium profiling systems.

Ideally suited for contemporary residences, premium commercial buildings, and high-end refurbishment projects, the L410 creates controlled separation between interior comfort and exterior conditions while maintaining thermal and acoustic performance. It pairs elegantly with minimalist flooring and anodised aluminium finishes in neutral tones.

The L410 door achieves Ud = 0.85 W/m²K, certified by ift Rosenheim, placing it in the top performance bracket for aluminium exterior doors. This value reflects exceptional insulation thanks to the 34 mm articulated thermal break system and quadruple glazing (triplex + Satinato glass + triplex), ensuring superior thermal comfort and significantly reduced energy costs.

The L410 door features 3 EPDM gaskets running along the entire frame, creating a multi-point seal that ensures surface-to-surface closure. These gaskets are resilient to temperature and humidity variations, maintaining performance throughout the door's service life. The system is tested and approved to European sealing standards for exterior doors, guaranteeing complete protection against rainwater and air infiltration.

Standard dimensions go up to 1100 × 2300 mm, and for single-leaf configurations, larger models can be realized up to 1200 × 2500 mm. For projects requiring other proportions or involving multiple leaves, we accept custom orders tailored to your specifications and compatibility with existing masonry. Our specialist team measures and calculates the optimal configuration for each space.

The L410 structure uses aluminium profiles with 3 mm thickness, combined with an articulated 34 mm thermal break that not only provides thermal insulation but also integrates rigid structural design. The frame has a total depth of 92 mm, and the leaf has a thickness of 92 mm, ensuring stability and resistance to deformation. The aluminium is treated with an anti-corrosion protective finish, and the quadruple glazing (44.1 triplex + Satinato + 44.1 triplex) completes the system's durability.

The L410 aluminium requires periodic cleaning with water and neutral detergent to maintain shine and prevent dirt buildup. EPDM gaskets should be inspected annually and replaced if they show signs of degradation. Closing mechanisms and hidden hinges should be lightly lubricated with neutral oils only if friction is observed. Aggressive or abrasive chemicals are not recommended, as they can damage the protective finish.

The L410 door is installed in standard wood, MDF, or aluminium frames, with adjustment of the frame depth (80 mm) to the existing masonry. Installation requires precise measurement of the opening, proper levelling, and secure fixing with plugs and anchors appropriate to the door's weight and profile. Consultation with a qualified installer is recommended to ensure perfect alignment and complete sealing with polyurethane foam or mortar. The system is compatible with all types of modern masonry (brick, concrete, stone).
