Aluminium exterior door L547 made to order

Aluminum exterior door L547 with high-performance profile and superior thermal insulation (Ud = 0.85 W/m²K). Modern system with triple glazing and EPDM seals for maximum weather protection.

The L547 is a contemporary solution for exterior access, engineered in aluminum with a refined profile and expansive dimensional capability. Available up to 1200×2500 mm in single-leaf configuration, it adapts seamlessly to large openings and modern architectural designs. The 3 mm aluminum skin delivers robust weather resistance without compromising visual elegance, while the 92 mm total system depth integrates naturally into contemporary masonry with an 80 mm frame depth.

Advanced thermal insulation is achieved through an articulated thermal break of 34 mm, substantially reducing heat loss and lowering supplementary heating demand. The triple-glazed unit—44.1 triplex / 5mm Satinato / 5mm triplex—delivers an exceptional Ud value of 0.85 W/m²K (certified by ift Rosenheim), controlling solar gain while attenuating external noise effectively. This construction strategy balances transparency with year-round climate control, critical for energy-conscious specifications.

Weather tightness relies on three EPDM gaskets positioned strategically across the frame, defending against water infiltration, air leakage, and dust ingress. The opening mechanism adapts to project requirements—swing, slide, or hybrid configurations—without degrading thermal performance. All components meet rigorous European testing standards, guaranteeing long-term reliability in exposed and demanding environments.

Available in custom dimensions within standard maximums, the L547 suits residential, commercial, and institutional projects where contemporary aesthetics meet functional rigor. The neutral aluminum profile accepts surface treatments—polishing, RAL-color coating, or anodized finishes—aligning with your building's architectural language. Its pairing with matching window systems, solar shading, or thermal mass facades creates coherent, high-performance envelopes.

The L547 is specified for premium renovations, passive-standard homes, and projects prioritizing carbon reduction. Installation demands precision, but the modular system ensures swift execution and professional outcomes—an investment architects and builders confidently recommend.

The L547 door achieves a thermal coefficient of 0.85 W/m²K, certified by ift Rosenheim, placing it in the high energy efficiency category. This performance is achieved through a 34 mm articulated thermal break and a premium triple glazing package with superior insulation, maintaining interior warmth and significantly reducing heating costs.

The L547 features a quadruple glazing system: 44.1 triplex + 5 mm Satinato + 44.1 triplex, providing superior thermal insulation and effective sound reduction. The asymmetric structure with laminated glass and acoustic dampening layers significantly reduces external noise transmission and ensures comfort in high-traffic areas, while the total system depth of 92 mm guarantees exceptional thermal performance.

The L547 can be ordered in standard dimensions up to 1100×2300 mm or, for a single leaf, up to 1200×2500 mm, perfectly adapted to your space. Any dimension within these limits can be made exactly to your frame size, with no gaps or sealing compromises, and installation ensures perfect alignment and optimal operation. We recommend precise opening measurements and consultation with our specialists to select the ideal configuration.

The L547 has a frame depth of 80 mm and total system depth of 92 mm, making it compatible with standard frames and modern masonry of 15-20 cm width. The modular system allows installation on new concrete walls, brick, or blockwork, with adjustable gaps for proper sealing with polyurethane or quality mortar. Installation requires precision in leveling and secure mechanical fixing; we recommend certified installers to guarantee maximum thermal performance and durability.

While complete security specifications (RC class) are not detailed in the available technical sheet, the L447 benefits from robust aluminum construction with 3 mm profile thickness and triple-laminated glazing system (44.1 triplex), ensuring high mechanical resistance to impacts and forced entry attempts. For precise anti-burglar classification assessment and secure hardware recommendations, we invite you to consult our specialists who will adapt the solution to your desired security level.

The aluminum L547 requires minimal maintenance: regular cleaning with mild soap and water on profiles and glazing, followed by drying with soft cloth. The triple EPDM gasket system should be wiped periodically and may require replacement after 8-10 years of intense weather exposure. For finishes, the aluminum can be supplied anodized (standard silver), lacquered in custom RAL colors, or with other protective treatments. We recommend checking the specific installation document for detailed instructions and recommended cleaning products.
