Aluminium exterior door L511 made to order

Aluminium entrance door with 92 mm profile depth and exceptional thermal performance (Ud 0.85 W/m²K). Quadruple glazing and triple EPDM sealing deliver premium weather and acoustic protection.

The L511 exterior door represents a premium aluminium entrance system engineered for residential and commercial buildings demanding superior thermal efficiency and architectural refinement. Structurally, the aluminium profiles—fabricated with 3 mm wall thickness—deliver lasting durability and weather resilience across diverse climate zones.

The construction system features a total profile depth of 92 mm, supported by an 80 mm frame assembly that provides structural rigidity and long-term stability. An articulated 34 mm thermal break strategically intercepts heat and cold transmission between interior and exterior. Glazing comprises quadruple panels in a composite arrangement (44.1 triplex + 5mm Satinato + 44.1 triplex), optimizing both acoustic insulation and thermal performance. Triple EPDM gaskets, distributed along the full perimeter, create a robust barrier against water infiltration and air leakage.

The certified thermal coefficient (Ud 0.85 W/m²K, ift Rosenheim standard) positions this door within Europe's highest performance tier, generating measurable energy savings and consistent internal comfort. The 92 mm leaf thickness and system compactness effectively reduce heat loss and acoustic transmission, making it ideal for exposed locations, high-moisture environments, or urban areas with elevated noise.

Standard installation accommodates apertures up to 1100×2300 mm, with extended options for single-leaf configurations reaching 1200×2500 mm. This dimensional flexibility enables seamless integration into varied architectural frames and accessibility requirements. Aluminium's inherent properties support diverse surface finishes and aesthetic customization.

Recommended for primary residential entrances, commercial facilities, thermally sensitive applications, and climate-variable regions. Full compatibility with radiant floor heating and modern HVAC systems ensures seamless integration into contemporary comfort strategies.

The 92 mm aluminium profile combined with an articulated 34 mm thermal break and quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) creates a reference thermal barrier. This configuration, tested and certified by ift Rosenheim, significantly reduces heat loss while maintaining interior comfort and lowering heating consumption.

Standard dimensions accommodate openings up to 1100×2300 mm and are ideal for most contemporary entrances. If you need a larger opening (up to 1200×2500 mm) with a single leaf, this option adapts to spacious entries without requiring a double door, providing an elegant and functional solution.

Quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) dissipates sound energy and reduces external noise transmission, while the opaque Satinato layer provides additional privacy. Triple EPDM gaskets create multi-point sealing that completely blocks water and wind infiltration, protecting the interior against weather and noise pollution, even in exposed locations.

Yes, the specified dimensions (1100×2300 mm standard and 1200×2500 mm single-leaf) are certified maximums. For adaptations to different measurements or masonry particuliarities, our team studies custom solutions without compromising the thermal and sealing integrity of the profile. We recommend consulting the showroom directly for your specific requirements.

The profile has a total depth of 92 mm (80 mm frame + 12 mm leaf overhang) and adapts to masonry of 90–100 mm, with the option to add adapters for different thicknesses. Installation requires mechanical fixing on provided anchors and sealing with mineral wool and silicone, ensuring a flush surface with the wall. For correct and safe installation, we recommend consultation with an approved installer.

Aluminium requires no painting and resists corrosion naturally, but benefits from periodic washing with water and soap to maintain its aesthetic appearance. Available finishes include anodizing in various tones (silver, anodic grey, brown, black), painting in RAL colours, or laminates with wood/stone imitation, which increase durability and provide long-term UV protection. EPDM gaskets can be replaced over time if they wear, ensuring continued sealing.
