Aluminium exterior door L543-2 made to order

L543-2 aluminium exterior door with slim profile and advanced thermal insulation Ud = 0.85 W/m²K. Quadruple-glazed system for maximum performance in residential and commercial spaces.

The L543-2 exterior door positions itself as a premium solution in the aluminium entrance door segment for residential and commercial buildings. Clean profile lines with a total depth of 92 mm deliver balanced proportions and subtle architectural presence. The system is engineered for durability under extreme weather conditions and long-term structural integrity.

The technical composition combines 3 mm aluminium with an articulated 34 mm thermal break, creating an effective barrier against heat loss. Frame depth of 80 mm and leaf thickness of 92 mm ensure stability and constructional solidity. The triple EPDM gasket sealing provides comprehensive water and air-tightness, essential for buildings in challenging climate zones.

Thermal performance certified by ift Rosenheim — Ud = 0.85 W/m²K — places it in the high-performance category, aligned with Europe's most rigorous standards. The quadruple glazing system (44.1 triplex / 5mm satin / 44.1 triplex) delivers superior sound insulation and optimal UV protection. Thermal resistance remains consistent across the entire door surface, eliminating cold spots.

Configurability ranges from standard dimensions of 1100 × 2300 mm to single-leaf options up to 1200 × 2500 mm. System flexibility accommodates diverse architectural approaches — from minimalist contemporary projects to sensitive interventions in heritage buildings. Pure aluminium requires no painting and maintains its original appearance throughout the product lifecycle.

Suitable for main entrances, commercial accesses, office spaces, and residential applications demanding high thermal insulation. Pairing with polished concrete, solid wood, or natural stone flooring amplifies visual impact. The L543-2 system meets security and performance standards for high-efficiency buildings.

The L543-2 achieves a Ud coefficient of 0.85 W/m²K, certified by ift Rosenheim, placing it among the highest-performing exterior doors on the market. This performance is delivered through quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) combined with a 34 mm articulated thermal break, ensuring maximum comfort and energy efficiency.

The L543-2 uses a 3 mm aluminium profile with a total leaf thickness of 92 mm, providing exceptional strength and durability. Aluminium combined with the 34 mm articulated thermal break and quadruple glazing creates a hybrid high-performance system that resists warping and requires minimal long-term maintenance.

The L543-2 is available in standard configuration up to 1100×2300 mm, and for single leaf doors, customization is possible up to 1200×2500 mm. The total system depth is 92 mm (frame depth: 80 mm), allowing adaptation to various wall thicknesses. Custom sizing is possible according to your requirements and structural specifications.

The L543-2 is equipped with 3 multi-point EPDM gaskets ensuring progressive sealing around the entire perimeter. The sealing system is tested to resist water and air infiltration under extreme conditions, working in synergy with the 92 mm depth and aluminium structure. EPDM guarantees long-term durability and maintained sealing properties over decades.

The L543-2 uses a quadruple glazing system: 44.1 triplex / 5mm Satinato / 44.1 Triplex, made from laminated glass layers combined with Satinato glass. This system provides exceptional thermal insulation, increased acoustic protection, and impact resistance, directly contributing to the Ud coefficient of 0.85 W/m²K. Quadruple glazing minimizes heat loss and enhances structural security.

Installing the L543-2 requires a frame with 80 mm depth, making it compatible with standard masonry (single bricks, autoclaved blocks). The total system depth of 92 mm provides sufficient space for sealing and insulation. Installation must be performed by qualified personnel, ensuring exact leveling and use of appropriate sealing and fastening materials (anchors, polyurethane foam).
