Aluminium exterior door L100 made to order

Exterior aluminium door with 92 mm profile depth and exceptional thermal performance (Ud 0.85 W/m²K). Quadruple glazing and triple EPDM gaskets ensure year-round comfort and weather protection.

The L100 exterior door positions itself as a premium solution for modern buildings requiring top-tier thermal performance and long-term durability. With a total system depth of 92 mm and aluminium profile thickness of 3 mm, it combines the lightness of metal with the solidity necessary for main entrances and high-traffic spaces.

The thermal insulation system relies on a 34 mm articulated thermal break, which significantly reduces heat loss. The 80 mm frame and 92 mm leaf are engineered to provide stability and flawless sealing. The quadruple glazing—composed of two 44.1 mm triplex layers with a 5 mm satin line between them—ensures both thermal and superior acoustic insulation, certified by German institute ift Rosenheim with a Ud coefficient of 0.85 W/m²K.

Sealing is achieved through three strategically positioned EPDM gaskets, eliminating any risk of water or air infiltration and maintaining interior comfort regardless of weather conditions. The system allows flexible sizing, with standard maximums at 1100×2300 mm and extended dimensions up to 1200×2500 mm for single leaves, offering adaptability to any architectural project.

The simple, linear design of the aluminium profile integrates effortlessly into contemporary façades, permitting combinations with large glazing and modern ventilation systems. The door can be customised in various opening configurations and surface finishes, adapting to minimalist aesthetics or projects with specific colour requirements.

This is the ideal solution for premium residential properties, offices, and commercial buildings prioritising energy efficiency and user comfort. Compatibility with intelligent opening systems and integration into smart automation solutions make the L100 a strategic choice for the contemporary developer.

Ud 0.85 W/m²K (certified by ift Rosenheim) indicates superior thermal insulation, significantly better than European standards for exterior doors. This is achieved through the combination of quadruple glazing and the articulated 34 mm thermal break in the aluminium frame. In winter, you'll experience minimal heat loss and a noticeable reduction in heating bills.

The 3 mm aluminium profile combined with quadruple 44.1 triplex glazing provides high mechanical resistance to impact. The 92 mm structure and three-point EPDM sealing create a solid foundation for high-quality hardware and concealed hinges. For maximum protection, we recommend adding RC2 or RC3 certified locks and hinges upon order, transforming the door into a certified anti-burglary element.

The quadruple glazing consists of four glass panes (2×44.1 triplex) separated by noble gas-filled spaces, with a 5 mm satin glass film in the middle. This configuration creates air chambers that trap heat and significantly reduce external noise. Benefits include exceptional thermal insulation, superior acoustic protection, and maximum mechanical resistance to wind and impact.

Yes, this door can be customised upon order. Standard maximum dimensions are 1100×2300 mm for a dual-leaf configuration and up to 1200×2500 mm for a single leaf. For projects with specific space requirements, our team can adapt the thickness, width, and height according to the architectural constraints of your location. We recommend a technical consultation to ensure compatibility with existing frames and masonry.

The 3 mm aluminium requires only periodic cleaning with water and neutral detergent to maintain its original appearance. EPDM gaskets should be inspected annually and lightly lubricated to maintain their elasticity and sealing performance. Hardware and concealed hinges require light cleaning and, in corrosive coastal climates, we recommend protective polishing. The painted or laminated finish remains stable for years without complex maintenance.

The 92 mm profile with 80 mm frame depth integrates into standard brick, concrete, or stone masonry frames of 80-100 mm. For buildings with external thermal insulation or narrow masonry (under 80 mm), specific adaptations or extension profiles may be needed. The triple EPDM gaskets ensure excellent sealing on irregular surfaces. During installation, we recommend verifying the opening dimensions and level line to ensure proper mounting and optimal operation.
