Aluminium exterior door L530-1 made to order

L530-1 aluminium exterior door with premium thermal performance (Ud 0.85 W/m²K) and quadruple high-insulation glazing certified by ift Rosenheim. Advanced 92 mm system depth with articulated thermal break ensures superior energy efficiency.

The L530-1 exterior aluminium door represents a premium solution for clients who demand the highest standards of thermal insulation and longevity. With a certified thermal coefficient of Ud 0.85 W/m²K from ift Rosenheim, this model ranks among the most energy-efficient doors available, delivering optimal comfort for demanding climates and zero-compromise living environments.

The system construction combines a total depth of 92 mm with an articulated thermal break of 34 mm, effectively interrupting heat transfer across the profile. The 3 mm aluminium layer provides exceptional rigidity and lifetime durability. Triple EPDM gaskets seal the entire perimeter, delivering perfect protection against water and wind infiltration—critical for exposed entrance points. The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex) ensures superior thermal performance, acoustic insulation, and anti-burglary security in a single integrated system.

Performance exceeds contemporary energy efficiency standards. The coordinated glass-profile-gasket system creates a continuous thermal barrier that minimises heat loss in winter while maintaining cool interiors in summer. ift certification confirms rigorous laboratory testing of airtightness, structural stability, and thermal cycling resistance. The 80 mm frame and 92 mm leaf allow secure installation on standard masonry and steel-frame structures.

The L530-1 accommodates versatile opening configurations within standard dimensions up to 1100×2300 mm, with single-leaf options extending to 1200×2500 mm. The profile integrates seamlessly with manual, semi-automatic, and electro-mechanical opening systems, adaptable to specific access requirements and operational patterns. RAL colour and finish options provide design flexibility for any architectural expression.

Perfect for contemporary residences, office buildings, and commercial spaces with exacting performance demands, the L530-1 completes passive house and nearly zero-energy façade assemblies. Paired with radiant floor heating and controlled ventilation systems, it maximises the benefits of superior insulation. The initial investment yields rapid returns through reduced heating and cooling costs, ensuring resident comfort and property value for decades.

With a Ud coefficient of 0.85 W/m²K (certified by ift Rosenheim), this door achieves premium energy performance — comparable to triple-glazed window insulation. The articulated 34 mm thermal break combined with the 92 mm system depth creates an effective thermal barrier that significantly reduces heat loss and lowers heating demand during winter months.

The door features a 92 mm thick leaf with 3 mm aluminium profile, while the frame accommodates an 80 mm depth, creating a robust 92 mm system total. The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) is laminated with satin-finished glass, providing both thermal insulation and light control. The articulated 34 mm thermal break interrupts the aluminium's thermal conductivity, preventing cold bridging effects.

Standard dimensions (single leaf) reach up to 1100×2300 mm, while a single pivot leaf can extend to 1200×2500 mm, allowing for impressive wide access. For spaces with different geometry, we accept customization orders — dimensions are not restricted to standard tables. We recommend precise measurement and consultation with our showroom team to determine the best solution for your opening.

The door features 3 strategically placed EPDM gaskets that create a continuous barrier around the leaf perimeter. Multi-point sealing works through controlled compression of gaskets when the door closes, blocking water infiltration and cold air. The 92 mm profile system and 80 mm frame depth allow sufficient overlap and uniform compression — essential for long-term effectiveness, regardless of extreme weather conditions.

The frame requires a minimum depth of 80 mm to accommodate the system frame. Standard installation is on reinforced masonry, with mechanical anchoring through aluminium columns. For pivot openings (allowing bidirectional opening), compatibility is integral to the system — hinges and pivot mechanisms come pre-calibrated. We recommend professional installation to ensure correct sealing and smooth operation throughout the door's lifespan.

Aluminium requires minimal maintenance — regular cleaning with neutral soap and water preserves the finish. EPDM gaskets should be inspected annually and cleaned to ensure continuous sealing. Available finishes include painted, veneered, and laminated options — each customizable in colours and textures to align with your home's exterior architecture. For specific colour details and finish availability, consultation with our showroom team is recommended.
