Aluminium exterior door L732 made to order

L732 aluminium entrance door with premium quadruple glazing and certified thermal performance (Ud 0.85 W/m²K). Contemporary design for modern residential and commercial facades.

The L732 is a premium aluminium entrance door designed for modern building facades that demand both performance and design clarity. With a total depth of 92 mm and frame depth of 80 mm, the 3 mm aluminium profile delivers structural rigidity and thermal efficiency in a slender, contemporary format. This system combines exceptional insulation properties with minimalist aesthetics, making it ideal for residential and commercial projects with clean architectural language.

The central performance feature is the 34 mm articulated thermal break, engineered to significantly reduce heat transfer between exterior and interior environments. The quadruple glazing system — constructed from 44.1 mm triplex, 5 mm Satinato interlayer, and 44.1 mm triplex — delivers outstanding acoustic and thermal insulation, particularly valuable in urban settings with noise and climate exposure. The triple EPDM gasket sealing system provides comprehensive protection against water infiltration and wind pressure, ensuring long-term durability and consistent interior climate control.

Energy performance is certified by ift Rosenheim with a thermal coefficient Ud of 0.85 W/m²K — a remarkable value for exterior doors that substantially reduces thermal losses and lowers the building's overall energy demand. The multi-layer construction and advanced insulation represent a responsible choice for sustainable building practices and climate efficiency. Testing to European standards confirms structural resilience and material durability across challenging weather conditions.

The L732 is available in standard dimensions up to 1100×2300 mm, with oversized options for single leaves reaching 1200×2500 mm. Aluminium finishing can be customised to match existing colour schemes, achieving seamless integration with the building's architectural character. Opening systems and configurations adapt to specific access requirements and interior flow patterns.

Recommended for contemporary residential homes, administrative buildings, retail centres, and hospitality projects where energy efficiency and modern design are paramount. It integrates seamlessly with coordinated window systems and exterior design elements, contributing to architectural coherence and premium visual impact.

Ud 0.85 W/m²K (certified by ift Rosenheim) is an exceptional thermal value for external doors, indicating minimal heat loss in winter and significantly reduced condensation on glass. This performance comes from the quadruple glazing (44.1 triplex + 5mm satin glass + 44.1 triplex), 92 mm frame depth, and the articulated 34 mm thermal break, placing L732 in the premium category with superior energy efficiency.

L732 features 3 mm aluminium thickness in both frame and leaf, with a total system depth of 92 mm, guaranteeing exceptional structural rigidity. The articulated 34 mm thermal break not only insulates thermally but also reinforces mechanical resistance. The high-quality Greek aluminium (GR origin) offers superior corrosion resistance and long-term dimensional stability, while the profile configuration ensures uniform load distribution.

Door L732 is equipped with 3 EPDM gaskets that create multi-point sealing around the entire perimeter where the frame meets the wall. The first gasket seals on the exterior side, the second in the middle, and the third on the interior, preventing water and wind infiltration even in extreme weather. This ensures consistent indoor comfort, reduces forced ventilation needs, and prevents outside noise discomfort.

Standard dimensions for L732 are 1100×2300 mm for typical openings. For special projects, the door can be ordered in custom variants up to 1200×2500 mm for single leaves. This flexibility allows adaptation to any masonry and façade configuration, ensuring perfect integration without requiring additional installation adjustments. We recommend consulting the design team for non-standard dimensions.

The 92 mm profile and 80 mm frame depth make L732 compatible with most standard frames and conventional masonry (brick, concrete). Installation is done by mechanically anchoring the frame to the masonry anchors, with precise level and plumb positioning, followed by isolation of the cavity with expanding polyurethane and final sealing. For renovation projects, it may require frame adjustments or compensation with adaptation profiles.

Aluminium L732 requires regular cleaning with soft cloths and neutral soapy water, followed by complete drying to prevent mineral deposits. The quadruple glazing (54.2 mm total thickness) is highly resistant to abrasion and thermal shock; cleaning is done with non-abrasive products. Hardware should be lightly lubricated annually, and EPDM gaskets maintain elasticity if not exposed to prolonged direct sunlight. The anodised or painted aluminium finish resists wear very well over time if aggressive chemicals are avoided.
