Aluminium exterior door L554 made to order

High-performance aluminium entrance door with L554 profile, quadruple glazing and thermal efficiency of 0.85 W/m²K. Premium external solution engineered for contemporary homes and commercial properties.

The L554 aluminium door is a premium external access solution engineered with technical precision for contemporary facade penetrations. The robust aluminium profile design, with a total system depth of 92 mm, delivers exceptional rigidity and longevity across diverse climatic conditions. The 3 mm aluminium finish and surface treatment ensure a refined aesthetic and superior corrosion resistance, suitable for high-end residential and commercial projects.

Innovative construction incorporates a 34 mm articulated thermal break that efficiently interrupts thermal bridges and delivers remarkable energy performance. The insulation system is complemented by a quadruple glazing unit combining 44.1 triplex layers with 5 mm Satinato glass, merging thermal isolation with light control and privacy. Triple EPDM gaskets ensure superior airtightness throughout the product lifecycle, minimizing periodic maintenance requirements.

Certified thermal performance (ift Rosenheim) with a Ud coefficient of 0.85 W/m²K positions this door among elite aluminium insulation standards. This exceptional value minimizes heat loss during cold seasons and substantially reduces building energy consumption. The 80 mm frame depth and 92 mm leaf thickness ensure outstanding structural resistance and flawless rigidity across all dimension ranges.

The model accommodates maximum dimensions of 1100×2300 mm in standard configuration and up to 1200×2500 mm for single leaf applications, enabling adaptation to varied entrance geometries. The swing opening system offers flexibility in spatial distribution and facilitates smooth circulation flow. The L554 profile integrates seamlessly with contemporary facades and minimalist design styles, remaining compatible with all flooring categories through flexible orientation capability.

Deployed in primary entrances of private residences, corporate headquarters and premium commercial spaces, the L554 combines technical reliability with modern architectural expression. The ideal choice for property owners prioritizing energy insulation, security and aesthetic purity in external access structures.

The Ud thermal coefficient of 0.85 W/m²K (certified by ift Rosenheim) places this door in the premium insulation category. The quadruple glazing—composed of two 44.1 mm triplex panes and a 5 mm satin layer—ensures a thermally robust barrier, suitable for harsh climates and low energy consumption. The insulation is enhanced by an articulated 34 mm thermal break within the aluminium profile.

The L554 door has a total depth of 92 mm, with the frame measuring 80 mm and the leaf panel matching this dimension. The raw aluminium is thin (3 mm), optimized for lightness and durability, while the core is lined with continuous thermal insulation. The 92 mm system depth allows efficient integration into standard masonry, maintaining structural rigidity and stability.

The quadruple glazing consists of two 44.1 mm triplex glass layers and a 5 mm satin layer in between. The 44.1 triplex configuration offers both safety—glass remains in the frame if broken—and enhanced acoustics. The central satin layer acts as a thermal buffer and reduces light reflections, creating fully effective thermal and acoustic insulation.

Standard dimensions are available up to 1100×2300 mm, and for single-leaf variants, limits extend to 1200×2500 mm. For requirements exceeding these parameters or different configurations, we recommend contacting the showroom to discuss custom manufacturing options. Any non-standard size is available with extended lead time.

The door is equipped with 3 EPDM gaskets arranged in a multi-point sealing perimeter, creating a continuous barrier against air infiltration and moisture. The gaskets are dimensioned to compress progressively upon closure, ensuring uniform sealing across the entire frame length. EPDM is a premium material, UV-resistant and tolerant to temperature fluctuations, guaranteeing long-term effectiveness.

With a system depth of 92 mm and frame of 80 mm, the door integrates into standard masonry openings, ensuring simple and stable installation. The aluminium profile has anchoring channels for fixing into concrete or masonry, and gaps are filled with thermally insulating polyurethane. For existing frames, we recommend compatibility inspection with the showroom specialist, as minor adaptations may be required.
