Aluminium exterior door L524-1 made to order

Aluminium entrance door L524-1 with outstanding thermal efficiency (Ud 0.85 W/m²K) and quadruple glazing for contemporary homes. Refined 92 mm profile delivers both aesthetic precision and robust weather protection.

The L524-1 exterior door represents a premium aluminium solution designed for contemporary residential entrances where energy performance and architectural refinement demand excellence. The compact 92 mm profile ensures seamless integration into modern façades while maintaining structural rigidity and flawless operational reliability.

The frame and leaf construction combines 3 mm aluminium with an articulated 34 mm thermal break that decelerates heat transfer and minimizes condensation risk. The quadruple glazing—twin triplex 44.1 mm panes framing a 5 mm satinato core—delivers a thermal transmittance coefficient of 0.85 W/m²K (certified by ift Rosenheim), exceptional performance for an entrance door. Triple EPDM gaskets provide comprehensive perimetral sealing and sustained resistance to thermal cycling and moisture exposure.

Acoustic insulation benefits substantially from the layered glazing architecture and the sealed profile system, reducing external noise to comfortable interior levels. The 92 mm system depth ensures superior load-bearing capacity across generous apertures—up to 1,200 × 2,500 mm for single-leaf installations, or 1,100 × 2,300 mm in standard configurations.

The door design accommodates personalization aligned with architectural intent—available in classical or contemporary opening mechanisms with adaptable dimensions and surface finishes. Aluminium finishes can be selected to integrate with contemporary colour palettes or create deliberate façade accents.

L524-1 suits luxury residences, premium commercial properties, office buildings with public entries, and refined retail environments. Compatibility with intelligent locking systems and security installations makes it ideal for owners committed to both thermal efficiency and residence protection.

The thermal coefficient Ud reaches 0.85 W/m²K, certified by ift Rosenheim, placing this door in the premium insulation category. This performance exceeds standard requirements and ensures minimal heat loss—critical for commercial and high-end residential applications.

The door is constructed from aluminium with 3 mm thickness, and the total profile depth is 92 mm. This construction ensures structural rigidity with minimal weight and allows for varied finishes, from anodizing to decorative lacquers. The articulated 34 mm thermal break prevents thermal conductivity and reduces condensation.

The quadruple glazing 44.1 triplex / 5mm Satinato / 44.1 Triplex ensures superior acoustic insulation and exceptional optical clarity. The four-layer configuration with laminated interlayers and 5 mm intermediate spacing attenuates external noise and provides uniform thermal protection across the entire surface.

Standard maximum dimensions are 1100×2300 mm, and for single leaf configurations, the door can be customized up to 1200×2500 mm. Custom orders are available—we recommend consulting our sales team for your specific sizing and frame adaptation needs.

The door is equipped with 3 high-quality EPDM gaskets ensuring multi-point sealing around the entire frame and leaf perimeter. EPDM gaskets are UV and oxidation-resistant, guaranteeing long-term durability and consistent protection against water, wind, and dust infiltration in all weather conditions.

Installation requires flat, clean masonry and a prepared frame according to building standards. The total system depth of 92 mm accommodates most standard frames. We recommend checking planarity tolerances and consulting our technical team for special considerations or adaptations for irregular masonry.
