Aluminium exterior door L390 made to order

Advanced aluminium exterior door with superior thermal performance (Ud = 0.85 W/m²K) and quadruple glazing. Precision engineering ensures weathertight sealing and lasting durability.

The L390 is a premium exterior solution engineered to exacting Greek standards and material specifications. The thermally treated aluminium profile delivers exceptional structural stability, with a 3 mm wall thickness and an articulated 34 mm thermal break system. This core architecture ensures performance integrity across diverse climatic conditions.

Construction depth totals 92 mm at the system level, with an 80 mm frame profile that accommodates all performance components. The quadruple glazing system—comprising 44.1 mm triplex, 5 mm satinato glass, and 44.1 mm triplex—delivers superior acoustic and thermal insulation across classified performance bands. Triple EPDM gaskets resist hardening, block water infiltration, and maintain seal integrity over decades of seasonal cycles.

The thermal transmittance value of Ud = 0.85 W/m²K (ift Rosenheim certified) positions this door in the high-performance category, significantly reducing heat loss and lowering HVAC demand in residential and commercial settings. This energy efficiency translates to enhanced indoor comfort and sustained operational cost savings, especially in climate-controlled environments.

Standard maximum dimensions of 1100×2300 mm expand to 1200×2500 mm for single-leaf configurations, offering maximum architectural flexibility. The door adapts seamlessly to renovation projects and new construction, with customization available for non-standard openings and manual or motorized operating systems.

In spaces demanding safety, durability, and year-round energy performance—residential entries, primary thresholds, mixed-use commercial frontages—the L390 serves as a premium barrier between interior climate and exterior exposure, upholding contemporary comfort standards.

The Ud coefficient of 0.85 W/m²K (ift Rosenheim certified) places this door in the very good performance category for exterior applications. This is achieved through the 34 mm articulated thermal break system and specialized quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex), which significantly reduces heat loss and maintains interior comfort even in harsh northern European climates.

The door is constructed from aluminium with 3 mm thick profiles and a total system depth of 92 mm. The frame reaches 80 mm, while the leaf has the same 92 mm depth, guaranteeing a robust and stable structure. The 34 mm articulated thermal break separates interior from exterior sections, preventing thermal bridging and ensuring optimal insulation.

The door features three high-quality EPDM gaskets that form a multi-point seal around the entire perimeter. These gaskets are resistant to temperature fluctuations and UV degradation, guaranteeing lasting protection against rain, snow, and wind penetration over years of use. The system is tested and certified to ift Rosenheim standards, ensuring that performance remains consistent even under extreme weather conditions.

Standard maximum dimensions are 1100×2300 mm, and for single-leaf configuration up to 1200×2500 mm is possible. For custom sizes beyond these parameters or special configurations (dual opening, asymmetrical symmetry), we recommend consulting with the showroom team who will verify compatibility with frame systems and constructive feasibility. Each custom order receives the same quality standards and certifications.

The quadruple glazing system (44.1 triplex / 5 mm Satinato / 44.1 Triplex) is a reference solution for advanced thermal and acoustic insulation. The 44.1 mm triplex glass consists of laminated layers that fragment sound vibrations, while the intermediate 5 mm Satinato layer serves as an additional damper. This configuration significantly reduces external noise, making it ideal for high-traffic locations, airports, or noisy urban areas.

The door is installed through the standard fixing system on the aluminum frame (80 mm frame depth), which is compatible with brick, cellular concrete, or stone masonry. For each construction type, frame depth and wall thickness must be evaluated to ensure secure installation and proper sealing. The showroom team provides technical consultation for opening preparation and compatibility with threshold systems (if applicable) and can recommend specific adapters for non-standard walls.
