Aluminium exterior door L554-1 made to order

Aluminium exterior door L554-1 with advanced thermal insulation (Ud 0.85 W/m²K) and quadruple glazing for superior energy efficiency and weather protection.

The L554-1 is a premium aluminium exterior door system engineered for residential and commercial applications demanding superior thermal performance and architectural sophistication. Manufactured to Greek standards (GR), this profile-based solution combines modern aesthetics with tangible energy efficiency benefits and extended product lifespan.

The 3 mm aluminium profile is integrated within a 92 mm total system depth, with 80 mm frame profiles that provide exceptional structural rigidity and stability. The articulated thermal break of 34 mm significantly reduces thermal bridging, while three-layer EPDM gasket seals ensure complete protection against air and water infiltration. The quadruple glazing system—featuring 44.1 mm triplex, 5 mm Satinato glass, and another 44.1 mm triplex—delivers outstanding thermal and acoustic insulation properties that exceed conventional standards.

Thermal performance is independently certified by ift Rosenheim with a Ud coefficient of 0.85 W/m²K, positioning this door among the highest-efficiency entrance solutions available. The substantial 92 mm leaf thickness accommodates high-performance glazing units and multiple sealing systems, ensuring durability and reliable operation throughout its service life.

The L554-1 is offered in standard configurations up to 1100 × 2300 mm in multi-leaf arrangements, or as a single leaf up to 1200 × 2500 mm. This dimensional flexibility permits seamless integration into diverse architectural settings, from residential entrances to commercial façades requiring weather resistance and thermal control.

Ideal for projects prioritising energy certification, thermal comfort, and noise reduction, the L554-1 entrance transforms building entrances into statements of performance and contemporary design, complementing minimalist and modern interiors.

The L554-1 achieves Ud = 0.85 W/m²K, a top-tier value for exterior aluminium doors certified by ift Rosenheim. This places it in the premium performance category, delivering excellent thermal insulation that significantly reduces heat loss and enhances interior comfort. The low coefficient is achieved through advanced insulation with a 34 mm articulated thermal break and quadruple glazing.

The L554-1 features a robust construction with 3 mm aluminium profile thickness, and the overall system achieves 92 mm total depth. The door leaf has the same 92 mm thickness, while the frame channel installed on the wall is 80 mm. This solid construction, combined with the articulated thermal break, ensures structural rigidity and lasting energy efficiency.

The L554-1 is equipped with high-performance quadruple glazing: 44.1 triplex / 5mm Satinato / 44.1 triplex. This configuration delivers superior thermal and acoustic insulation, significantly reducing heat transmission and external noise. The Satinato glass in the middle layer also provides partial privacy, while the triplex layers ensure safety and impact resistance.

The L554-1 can be manufactured in standard dimensions up to 1100×2300 mm, or as a single-leaf door up to 1200×2500 mm for larger openings. All dimensions are fully customizable to order based on your space requirements and wall thickness. Consult with the installation team to confirm the optimal dimensions for your location.

The L554-1 features a multi-point sealing system with 3 EPDM gaskets, ensuring hermetic closure and preventing water and air infiltration. The hinge system is designed for maximum performance and long-term durability, with smooth and silent operation. The EPDM gaskets are UV-resistant and tolerant to temperature fluctuations, guaranteeing functionality throughout the door's lifetime.

The L554-1 requires professional installation into a prepared frame that must accommodate the system's 92 mm depth. It is compatible with most masonry types – concrete, brick, stone – provided the frame is correctly positioned and level. Sealing and thermal performance depend heavily on installation quality, which is why we recommend using an experienced installer.
