Aluminium exterior door L541 made to order

L541 exterior aluminium door with exceptional thermal performance and quadruple glazing. Premium entry solution featuring deep thermal break and advanced sealing technology.

The L541 exterior door represents a premium entry solution crafted from high-grade aluminium originating from Greece. The 92 mm system depth ensures seamless integration with contemporary façades, while the robust 80 mm frame provides structural stability and optimal load distribution. The 3 mm aluminium section is precision-engineered to deliver a refined appearance and enduring performance across all seasons.

Construction and material selection reflect European performance standards. The quadruple glazing — 44.1 triplex / 5mm Satinato / 5mm Satinato / 44.1 triplex — combines acoustic isolation with visual refinement through its satin finish. Three EPDM gaskets establish an effective barrier against infiltration and wind pressure, safeguarding interior comfort year-round.

Thermal efficiency reaches Ud 0.85 W/m²K (ift Rosenheim certified), positioning this door within low-energy building standards and representing a sound investment for high-performance architecture. The articulated 34 mm thermal break prevents heat transfer between inner and outer profiles, maintaining interior climate control and reducing operational energy demands. The system accommodates leaf dimensions up to 1200×2500 mm, offering flexibility for expansive entrance designs.

The minimalist profile design integrates effortlessly into contemporary, brutalist, or industrial architectural schemes. Standard swing opening permits customization—side-hung, centre-hung, or automated systems—based on project requirements. The 92 mm leaf thickness conveys structural integrity and presence without visual heaviness, earning recognition in both residential and selective commercial applications.

L541 is recommended for primary residential entries, premium office environments, and upscale commercial spaces where isolation and aesthetic refinement are priorities. It pairs naturally with polished concrete, marble, solid timber, or ultra-fine porcelain flooring—materials that reflect commitment to quality and architectural precision. Professional installation on metal frameworks or concrete structures ensures the finished entry communicates solidity and refined architectural intent.

The L541 achieves a thermal coefficient Ud of 0.85 W/m²K (ift Rosenheim certified), an exceptional value for primary entrances. This results from the 92 mm system depth, articulated thermal break of 34 mm, and quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex), which minimizes heat loss and significantly reduces heating costs over time.

The L541 is available in standard dimensions up to 1100 × 2300 mm, with single-leaf configurations reaching 1200 × 2500 mm. As a modular aluminium system, it allows custom sizing to order, adapted precisely to your masonry. We recommend precise measurements and consultation with the installation team to ensure proper fit.

The L541 features a hybrid structure: 3 mm thick aluminium profile for strength and stability, a 92 mm core with articulated 34 mm thermal break preventing thermal conductivity, and laminated quadruple glazing. Sealing is achieved with 3 EPDM gaskets around the perimeter, ensuring long-term weather resistance and acoustic insulation. The Greek-origin aluminium is treated to resist corrosion.

The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex) combines thick laminated glass with a 5 mm air gap, significantly reducing external noise. The laminated construction and spacing between panes create multiple acoustic reflection points, attenuating low to mid frequencies typical of traffic and urban environments. The Satinato adds extra sound damping.

The L541, with total depth 92 mm (frame 80 mm + leaf 92 mm), requires precise opening preparation and stainless steel anchors for masonry attachment. The system is compatible with standard aluminium and PVC frames, low-threshold or threshold-free configurations, and adapts to brick, concrete, and block walls. Installation must be level and square, with polyurethane foam sealing around the perimeter essential to prevent water infiltration.

The L541 aluminium door with corrosion treatment requires regular cleaning with warm water and neutral detergent to remove dirt and salt deposits (especially in coastal areas). EPDM gaskets should be inspected annually and lubricated with silicone, and any scratches or paint chips should be touched up promptly to prevent oxidation. Avoid abrasive cleaners and stiff brushes that can damage the finish.
