Aluminium exterior door L514 made to order

Aluminium exterior door with slim profile and superior thermal performance (Ud 0.85 W/m²K). Quadruple glazing with Triplex lamination ensures security and exceptional acoustic comfort.

The L514 model is positioned as a premium solution in the aluminium exterior door range, combining robust construction with top-tier energy efficiency. The compact profile, with a system depth of 92 mm, enables elegant integration into any modern facade without compromising thermal insulation or structural integrity.

The entire system's construction is based on 3 mm aluminium with an articulated thermal break of 34 mm, which minimises thermal bridging and maintains dimensional stability over time. The three-band EPDM gasket system ensures uniform air tightness, reducing infiltration and optimising interior climate control. The special glazing—a quadruple system featuring Triplex laminated glass on both outer layers—delivers superior impact resistance and proven acoustic protection.

Certified thermal performance (Ud 0.85 W/m²K, according to ift Rosenheim testing standards) places this door in the top category for European climates. Acoustic insulation benefits fully from the 92 mm leaf thickness and the complex glazing system, making it ideal for spaces exposed to ambient noise. Load capacity and wind resistance are guaranteed for standard openings up to 1100×2300 mm, with the option of single-leaf configurations reaching 1200×2500 mm.

Customisation encompasses a wide range of dimensions and opening configurations—classic hinged systems, pivot variants or sliding solutions, adaptable to any usage scenario. The aluminium finish allows application of coatings in any RAL profile, offering creative freedom in facade design without compromising structural integrity.

The L514 is ideally suited for main entrances in modern residences, corporate offices or commercial buildings requiring dignified and efficient access solutions. Pairing with premium solid wood or porcelain tile flooring creates elegant transitions between interior and exterior, reinforcing the impression of quality and attention to detail.

The L514's quadruple glazing—44.1 Triplex / 5mm Satinato / 44.1 Triplex—delivers superior thermal and acoustic insulation. The fourth pane and Triplex lamination minimize heat transfer and external noise, ensuring remarkable energy efficiency, with a Ud coefficient of 0.85 W/m²K reflecting this performance.

The articulated 34 mm thermal break in aluminium separates the outer profile from the inner frame, preventing cold transfer. This design allows a total system depth of just 92 mm without compromising insulation, maintaining an elegant slim-line aesthetic. The result is superior condensation control and consistent thermal comfort, even in harsh climates.

The L514 can be ordered in standard dimensions up to 1100×2300 mm, or as a single leaf up to 1200×2500 mm for larger openings. Custom configurations are tailored to your specific needs and frame compatibility—we recommend consulting our team to ensure perfect fit to your existing masonry and profiles.

The L514 uses three-point EPDM gaskets that ensure superior perimeter sealing—eliminating water and wind infiltration risk. The combination of articulated profiles and 92 mm leaf thickness guarantees consistent protection even in extreme weather conditions. This means long-term durability and reduced energy loss.

The L514 uses 3 mm aluminium profiles with an 80 mm frame depth, providing structural stability and durability over time. While specific anti-burglary class ratings are not detailed in the standard configuration, the premium aluminium and 92 mm leaf thickness offer solid protection for residential use, with the option to upgrade with advanced security hardware and concealed hinges for additional security.

L514 installation requires the frame and masonry to be in good condition, with an opening precisely matching your ordered dimensions. We recommend checking the frame level and plumb before installation, and ensuring compatibility with existing threshold systems and sealing profiles. Our consultants can assess your location and recommend specific preparations to ensure seamless installation and optimal long-term sealing.
