Aluminium exterior door L511-5 made to order

Aluminum exterior door with slender profile and certified thermal insulation. Robust construction featuring an articulated thermal break and quadruple glazing for premium comfort.

The L511-5 aluminum door represents the exterior access solution for homeowners who prioritize energy efficiency and durability. This door combines the elegant slenderness of its profile—92 mm total system depth—with the structural rigidity needed to withstand climate demands. The design is pure and restrained, equally suited to contemporary and classical architecture.

The 3 mm aluminum profile is fitted with an articulated thermal break of 34 mm, which effectively interrupts energy transmission between outside and inside. The quadruple glazing—stratified as 44.1 triplex, 5 mm satin glass, and 44.1 triplex again—ensures balance between insulation and optical clarity. Triple EPDM seals prevent water and air infiltration, guaranteeing long-term airtightness even in high wind conditions.

Thermal performance certified by ift Rosenheim establishes a heat transfer coefficient Ud of 0.85 W/m²K—a value that positions the door in the premium segment of access systems. This insulation level translates to reduced energy loss, consistent indoor comfort, and minimal environmental impact. The total system depth of 92 mm allows easy integration into various wall thicknesses and existing structures.

Available in standard configurations up to 1100 × 2300 mm or single-leaf option up to 1200 × 2500 mm, the door adapts to most entrance spaces. Traditional swing opening delivers reliability and ease of operation without dependence on complex automation systems. The profile accommodates mounting in various orientations—façades, side walls, or interior walls with optional solar shading.

The L511-5 integrates seamlessly into modern homes with minimalist finishes, and equally into renovations of classical properties seeking discreet improvements in insulation and aesthetics. Paired with solid wood flooring, stone-look porcelain, or patinated concrete, this door amplifies the authority of your entrance space. It is recommended for homeowners who understand that a well-crafted detail—however modest—transforms daily experience at home or work.

The L511-5 achieves a thermal coefficient Ud of 0.85 W/m²K, certified by ift Rosenheim, placing it among the highest-performing exterior doors. This is achieved through the combination of a 34 mm articulated thermal break and quadruple glazing (44.1 triplex / 5mm satin / 44.1 triplex), ensuring superior thermal comfort and reduced heat loss during cold periods.

The L511-5 uses 3 mm aluminium profile thickness integrated into a system with total depth of 92 mm, ensuring optimal structural rigidity without compromising ease of handling. The thin profile is made possible by the 34 mm articulated thermal break that provides stability and resistance to deformation, maintaining thermal insulation and multi-point sealing throughout the product's lifetime.

The L511-5 offers two dimensional options: standard configuration up to 1100×2300 mm and single-leaf configuration up to 1200×2500 mm. Beyond these maximum dimensions, the product can be customized upon request to meet your specific needs, ensuring perfect adaptability to any architectural project and space configuration.

The L511-5 is equipped with 3 EPDM gaskets that form multi-point sealing around the entire frame perimeter, effectively preventing water and wind infiltration in extreme weather conditions. These high-quality gaskets are combined with the total system depth of 92 mm and articulated thermal break, creating a complete barrier that protects the interior of the home and reduces thermal losses.

The L511-5, with total depth of 92 mm and frame depth of 80 mm, is installed according to European construction standards, integrating into the frame and masonry through anchoring on three or four sides. The system allows adaptation to different wall thicknesses and masonry types (concrete, brick, insulation), and hidden hinges and hardware are configured for standard and pivot openings, ensuring optimal long-term operation.

The L511-5 is designed with security in mind through a combination of robust hardware, hidden hinges, and multi-point sealing that eliminates common weak points. While exact RC (Resistance Class) specifications are not detailed in the technical sheet, the advanced construction system with premium aluminium profile and 92 mm leaf thickness offers significant structural resistance, being certified according to European performance standards. For the exact burglary protection level (RC2 or RC3), we recommend consulting with our specialist who can adapt the hardware and locking mechanisms based on your location's specific risk.
