Aluminium exterior door L394 made to order

Aluminium exterior door with quadruple glazing and exceptional thermal insulation (Ud=0.85 W/m²K), engineered for demanding climate conditions and modern residential spaces.

The L394 exemplifies premium exterior door engineering, built with a 3 mm aluminium profile and an articulated thermal break system of 34 mm depth. The total system depth of 92 mm ensures structural rigidity and weather resistance, positioning it among high-performance doors for contemporary residential and small commercial applications.

The quadruple glazing—composed of 44.1 mm triplex / 5 mm Satinato / 44.1 mm triplex—delivers exceptional acoustic and thermal protection while maintaining refined aesthetics. Triple EPDM gaskets provide complete sealing and outstanding durability against climatic stress. The aluminium construction and surface treatment guarantee long-term corrosion resistance with minimal maintenance.

With a thermal coefficient of 0.85 W/m²K (ift Rosenheim certified), this door achieves elite-level insulation performance, significantly reducing heat loss while maintaining consistent interior comfort. The deep profile structure—80 mm frame and 92 mm leaf—accommodates thickened glazing and advanced security systems. Mechanical strength and seismic flexibility are assured through robust design principles.

Standard dimensions up to 1100×2300 mm, with customization available to 1200×2500 mm for single-leaf configurations, provide flexibility across diverse projects. The door adapts seamlessly to contemporary and minimalist architectural styles, with opening configurations including hinged, sliding, or hybrid systems.

Ideal for residences in temperate or arctic climates, offices demanding high energy efficiency standards, and commercial spaces where acoustic and thermal insulation are paramount. Pairs elegantly with timber flooring, polished concrete, or natural finishes, creating a cohesive entry statement.

With a thermal coefficient Ud of 0.85 W/m²K (certified by ift Rosenheim), this exterior door ranks among the most efficient on the market. The articulated 34 mm thermal break and quadruple glazing system minimize heat loss significantly, making it ideal for harsh winters and reduced energy consumption.

The frame and leaf are constructed from aluminum profiles with 3 mm thickness. The total system depth is 92 mm (frame depth 80 mm), with a 92 mm dense and robust leaf. Aluminum provides excellent corrosion resistance and durability in varying climates with minimal maintenance.

Standard configurations support a maximum of 1100×2300 mm. For single-leaf doors, you can reach 1200×2500 mm. We customize dimensions to fit your exact opening and existing masonry, ensuring perfect installation.

The door features 3 EPDM multi-point gaskets that ensure perfect sealing against water and wind infiltration. Combined with the thick quadruple glazing (44.1 triplex on both sides), this system provides excellent acoustic insulation for noisy external environments.

The robust aluminum profile system and quadruple glazing provide a solid security foundation. The door is compatible with advanced security hardware (multi-point locks, concealed hinges) and can be configured to RC2/RC3 standards upon request, depending on your desired protection level.

Installation requires frame systems compatible with the aluminum profile and 92 mm system depth. We verify compatibility with your existing masonry (brick, concrete, stone) before installation. The threshold is installed at the base with concealed hinges and exterior sealing for a clean, durable finish.
