Aluminium exterior door L372-10 made to order

High-performance exterior aluminum door L372-10 with advanced thermal insulation, 92 mm profile depth, and quadruple Satinato glazing. A premium solution that delivers superior energy efficiency and contemporary style.

The L372-10 exterior aluminum door is a reference choice for property owners investing in durable, high-performance exterior access. The 92 mm profile depth, reinforced by an articulated 34 mm thermal break, delivers exceptional thermal performance with a Ud coefficient of 0.85 W/m²K, certified by ift Rosenheim. This profile thickness is the signature of a robust system designed to support the weight and stresses of a premium exterior door.

The 3 mm aluminum material, paired with triple EPDM sealing gaskets, creates a secure barrier against weather elements. The quadruple glazing system — 44.1 triplex/5mm Satinato/44.1 triplex — provides both acoustic and superior thermal insulation, while the Satinato finish offers a discreet, elegant aesthetic suitable for any contemporary architectural context. This multi-layered approach ensures durability and longevity in demanding outdoor conditions.

Thermal performance is the standout strength of this door. With a Ud coefficient of 0.85 W/m²K, the L372-10 ranks among premium exterior doors with exceptional insulation, significantly reducing heating costs during cold months. The 34 mm articulated thermal break prevents cold bridging at the junction between profile and adjacent elements, maintaining thermal comfort across the entire perimeter. The total system depth of 92 mm, compared to the frame depth of 80 mm, allows elegant integration into the exterior wall without compromising structural integrity.

Standard dimensions up to 1100×2300 mm cover most residential openings, with an extended single-leaf option up to 1200×2500 mm for more generous spaces. The system allows personalized adjustments based on site conditions and project requirements. The Satinato finish imparts a refined presence, integrating harmoniously regardless of façade style. Customization options ensure the door complements both modern minimalist and contemporary classical designs.

The L372-10 is recommended for modern residences with high energy standards, premium-grade renovations, and buildings in cold or temperate climate zones. The combination of high-performance thermal insulation, acoustic sealing, and uncompromising design makes it the ideal choice for discerning homeowners who refuse to compromise on durability and efficiency.

With a thermal coefficient Ud of 0.85 W/m²K (ift Rosenheim certified), this door ranks among the highest-performing exterior access points, ensuring minimal heat loss and significantly reducing heating costs. The 92 mm system depth combined with the articulated 34 mm thermal break and specially designed quadruple glazing maintains stable interior climate even during extreme weather conditions.

The structure is built on an aluminium profile with 3 mm wall thickness, delivering extreme rigidity without excess weight. Insulation is integrated through a 34 mm articulated thermal break, and the glazing features a quadruple configuration with 44.1 mm triplex layers, 5 mm Satinato glass, ensuring premium thermal and acoustic insulation with optical clarity and visual comfort.

The system offers great customization flexibility: standard maximum dimensions are 1100×2300 mm, but for larger openings or special shapes, single-leaf configurations can be produced up to 1200×2500 mm. Any custom modifications are manufactured directly at the factory, ensuring precise fitting to your frame proportions and specific architectural requirements.

Multi-point sealing is achieved through 3 high-performance EPDM gaskets, creating a complete barrier against water infiltration and air leaks around the entire door perimeter. Combined with the special quadruple glazing (with triplex and Satinato glass layers), this solution delivers superior acoustic attenuation, ideal for homes in congested urban areas or near transportation routes.

Due to the 3 mm aluminium construction with optimized core and quadruple glazing, the door carries substantial but balanced weight, requiring professional installation by specialists. Hardware and hinges are specifically sized for this mass, and post-installation adjustment is critical for smooth long-term operation; we recommend requesting installation services from the supplier or a certified craftsman experienced with premium aluminium systems.

The L372-10 aluminium requires minimal maintenance: regular cleaning with lukewarm water and neutral detergent on exterior surfaces followed by drying with a soft cloth prevents debris accumulation and corrosion. EPDM gaskets should be inspected annually and lightly treated with neutral silicone to maintain elasticity; in salt-prone climates (coastal zones), more frequent cleaning is recommended. Hardware does not require lubrication from the factory—replace any damaged components quickly to prevent operational compromise.
