Aluminium exterior door L541-2 made to order

Aluminium exterior door with 92 mm system depth and exceptional thermal performance (Ud = 0.85 W/m²K), featuring quadruple glazing for maximum energy efficiency. Premium hinged door solution for main entrances and transition spaces.

The L541-2 exterior door is an aluminium solution with a 92 mm system profile, designed to deliver exceptional thermal performance at main entrances and transition spaces. Positioned in the premium hinged door category, it combines robust construction with refined finishes that integrate seamlessly into both contemporary and classical architectural expressions.

The 3 mm aluminium profile incorporates an articulated thermal break of 34 mm, significantly reducing heat transmission. The quadruple glazing — 44.1 triplex / 5mm Satinato / 44.1 triplex — provides superior thermal isolation while the satinato treatment subtly filters light and preserves privacy with understated elegance. Three-level EPDM sealing gaskets ensure flawless airtightness across the entire perimeter.

Certified thermal performance (Ud = 0.85 W/m²K, ift Rosenheim tested) positions this door among the highest-performing aluminium solutions on the market. The low heat transmission coefficient ensures interior comfort and substantial energy consumption reduction, particularly relevant for cold climates or NZEB-certified buildings. Total system depth of 92 mm, with leaf and frame proportions of 92 mm and 80 mm respectively, delivers structural stability and superior insulation capacity.

Standard dimensions reach 1100 x 2300 mm, with single-leaf options up to 1200 x 2500 mm, providing flexibility for diverse residential and commercial facade integration. The hinged opening system ensures effortless operation suitable for high-traffic areas.

This exterior door is recommended for luxury residential projects, architectural renovations, and commercial applications demanding certified thermal performance and refined aesthetics. It complements premium natural stone, high-end porcelain, or solid wood parquet in principal entrance spaces.

A Ud value of 0.85 W/m²K indicates superior thermal performance — the door loses very little heat during cold seasons, thanks to the articulated 34 mm thermal break and quadruple glazing system. This rating places the door in the high energy comfort category, significantly reducing energy losses and contributing to more efficient climate control throughout the building.

The door features three EPDM gaskets of high quality positioned around the entire frame perimeter — top, left and right pillar — ensuring uniform sealing against air and water infiltration. Hinges and closing mechanisms are integrated into the aluminium profile, delivering a clean visual appearance and smooth long-term operation.

The L541-2 is available in standard version up to 1100×2300 mm and in single-leaf version up to 1200×2500 mm, allowing adaptation to non-standard openings. Any dimension outside the standard ranges is manufactured to order according to project requirements — contact the showroom team for technical recommendations on proportions and structural stability.

The quadruple glazing consists of four glass layers (44.1 triplex / 5mm Satinato / 44.1 triplex) creating a multi-layer insulating space — the laminated glass layers (triplex) absorb vibrations, and the gaps between them function as acoustic barriers. This configuration significantly reduces external noise transmission, ideal for main entrances in busy areas or near heavy traffic, while providing superior thermal insulation.

The L541-2 with a frame depth of 80 mm is installed on frames aligned to the opening dimensions and fixed with anchors into the wall according to building standards. Compatibility with existing frames depends on their dimensions and wall condition — the installation team recommends a site survey to confirm adaptability and identify any necessary preparatory work.

The aluminum profile of the L541-2 should be cleaned regularly with soft water and neutral detergent, and EPDM seals checked periodically to maintain elasticity. For painted finishes, avoid harsh solvents and abrasive products; in coastal areas or high-pollution zones, more frequent washing is recommended. Lubricating the closing mechanism once a year with silicone grease ensures smooth and durable operation.
