Aluminium exterior door L350 made to order

L350 aluminium entry door with 92 mm system depth and exceptional thermal performance Ud 0.85 W/m²K, engineered for contemporary entrances.

The L350 aluminium entry door is engineered for residential and commercial projects demanding superior insulation and structural resilience. The aluminium profile system, 92 mm in total depth, delivers exceptional rigidity and an unfinished surface compatible with any façade colour scheme.

With a frame depth of 80 mm and leaf thickness matching 92 mm, the construction features 3 mm aluminium wall thickness throughout. The articulated thermal break of 34 mm effectively isolates thermal bridging zones. Glazing consists of a quadruple configuration — two 44.1 mm Triplex layers with 5 mm Satinato interlayer — providing superior thermal insulation and controlled natural light diffusion. Three perimeter EPDM gaskets ensure durable weather sealing.

The thermal coefficient Ud 0.85 W/m²K, certified via ift Rosenheim testing, positions this door in the premium performance category for temperate and cold climates. The system accommodates standard dimensions up to 1100×2300 mm, with single-leaf capacity reaching 1200×2500 mm for maximised openings and light penetration.

L350 adapts seamlessly to hinged, sliding, or pivot configurations and supports finish customisation according to project requirements. Aluminium eliminates periodic maintenance and resists degradation in maritime or industrial-urban environments.

Ideal for primary entrances in upscale residences, office buildings, and premium residential spaces where first impression and energy performance are paramount. Integration with automation and access control systems is available for high-end applications.

The thermal coefficient Ud is 0.85 W/m²K, certified by ift Rosenheim — an excellent value for exterior doors. This performance comes from the 92 mm leaf thickness, 34 mm articulated thermal break, and quadruple glazing with triplex, significantly reducing heat loss and long-term heating costs.

The L350 door features an aluminium construction with an insulating core, total thickness 92 mm. The aluminium profile is 3 mm thick, with an articulated thermal break of 34 mm that ensures high thermal performance. The frame is 80 mm deep, and the quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex) combines modern design with functionality.

Standard maximum dimensions are 1100×2300 mm, and for a single leaf up to 1200×2500 mm. For specific projects requiring non-standard sizes or proportions, L350 doors can be custom-ordered directly from the manufacturer. We recommend contacting the showroom team to discuss your project's exact requirements.

The L350 door is equipped with 3 EPDM gaskets forming a multi-point seal around the perimeter. These high-quality elastomer gaskets absorb vibrations, prevent water ingress and air leakage, and maintain airtightness long-term, even in extreme weather. The system is tested and certified to international standards.

The L350 door, with a frame depth of 80 mm and total system depth of 92 mm, fits most standard constructions in concrete, brick, or timber. For proper installation and optimal compatibility with your wall structure, we recommend on-site inspection by our expert team, who will ensure frames and walls are correctly prepared for seamless installation.

The L350 aluminium door requires regular cleaning with water and mild detergent on aluminium and glass surfaces. EPDM gaskets should be inspected annually and lightly lubricated if needed to maintain elasticity. Avoid abrasive or harsh chemical solutions that could damage the anodised finish. With minimal maintenance and regular cleaning, the door will retain its appearance and performance for years.
