Aluminium exterior door L906 made to order

High-performance aluminium exterior door with advanced thermal break and quadruple glazing, engineered for superior energy efficiency and lasting durability.

The L906 model represents a premium solution for exterior openings, engineered to exceptional performance standards. Built with qualified aluminium and modular architecture, this door type sits in the upper segment, designed for modern residential projects and buildings with stringent thermal isolation requirements.

The structural profile spans a total depth of 92 mm with a frame depth of 80 mm and leaf thickness matching that dimension. The aluminium section measures 3 mm, ensuring rigidity and dimensional stability over time. The articulated thermal break of 34 mm serves as the critical barrier against heat transfer, maintaining robust energy performance year-round. The sealing system—three EPDM gaskets—provides continuous protection against air and water infiltration, essential for European climates.

Glazing follows a quadruple configuration: two protective layers of 4.4 mm laminated triplex enclose a 5 mm satin glass insert, followed by a final 4.4 mm triplex layer, creating a formidable acoustic and thermal shield. The certified Ud value of 0.85 W/m²K (ift Rosenheim) positions this door in the upper tier of thermal efficiency. Standard dimensions reach 1100×2300 mm, with extended options up to 1200×2500 mm for single leaves, offering flexibility across diverse aperture sizes.

The restrained design and refined profile proportions integrate seamlessly into contemporary facades, minimalist spaces, or architecturally distinctive interiors. The generous system depth guarantees acoustic comfort and thermal control, reducing reliance on supplementary climate systems. Customization encompasses opening configurations adapted to functional needs—swing, sliding, or pivot—and surface finishes compatible with modern metallic or RAL colour palettes.

Recommended for single-family residences, high-end apartment buildings, offices, and premium commercial spaces. Pairs harmoniously with solid wood, polished concrete, or natural ceramic flooring, creating transitions between interior and exterior with visual clarity and consistent thermal comfort. Investment in thermal performance yields recovery through reduced energy consumption season after season.

With a thermal coefficient of 0.85 W/m²K (ift Rosenheim certified), this door ranks among high-performance exterior solutions, comparable to a well-insulated wall system. Heat loss through the door is minimized, resulting in measurable reductions in heating consumption and energy bills—particularly significant for properties in cold climates.

The frame features 3 mm aluminum profiles with an articulated 34 mm thermal break—combining lightweight strength with structural rigidity. The quadruple glazing system (44.1 triplex + 5mm Satinato + 44.1 triplex) delivers impact resistance and weather durability. Aluminum doesn't warp, rot, or corrode, maintaining functionality and appearance reliably through decades of exposure.

The L906 features multi-point sealing through 3 EPDM gaskets, ensuring both thermal retention and effective acoustic insulation. The hinge and hardware system is engineered to support the full weight of a 92 mm leaf panel, guaranteeing secure closure and smooth operation. Robust construction and premium-grade components prevent infiltration and provide long-term resistance to mechanical stress and wear.

Standard dimensions are 1100×2300 mm, with single-leaf configurations available up to 1200×2500 mm. For project-specific requirements—unusual dimensions, double configurations, or custom proportions—we recommend consulting our design team. Each door is manufactured bespoke according to DWG drawings and site specifications, ensuring perfect integration within the architectural context.

The L906 requires flat, plumb masonry with a minimum frame depth of 80 mm (matching the profile depth). When replacing an existing door, checking opening dimensions and tolerances is essential—variations exceeding 5 mm require local frame adjustments. Installation uses anchors and polyurethane mortar, with professional caulking ensuring complete sealing and long-term alignment. We recommend coordinating with your installer before ordering.

Aluminum is available in RAL paint finishes, anodized natural tones (Bronze, Titanium, Stainless), or laminated wood-effect veneers. Maintenance is minimal—periodic cleaning with neutral soap and water, avoiding abrasive cleaners. EPDM gaskets should be checked annually and gently cleaned to maintain elasticity. Industrial-grade anodizing and paint are UV and corrosion resistant, requiring no additional treatment. The door maintains performance throughout its lifespan without replacement of critical components.
