Aluminium exterior door L270 made to order

High-performance aluminium exterior door with ultra-slim profile and exceptional thermal coefficient Ud 0.85 W/m²K. Quadruple glazing system with triple EPDM sealing and Satinato glass for superior insulation and contemporary aesthetics.

The L270 model represents a new generation of high-performance aluminium exterior doors engineered to meet the exacting demands of European climate standards. Built with high-density aluminium extrusions, the door frame delivers long-term structural stability, while its compact 92 mm system depth eliminates visual bulk from the facade. Positioned in the premium segment, this door merges rigorous engineering with understated contemporary elegance.

Thermal performance is the cornerstone of this design. The L270 features an articulated thermal break of 34 mm that interrupts heat transfer and maintains temperature differential between interior and exterior environments. The 3 mm aluminium profile is treated with a protective anodised coating, providing durability against corrosion and UV discolouration. The quadruple glazing configuration—featuring 44.1 mm triplex panes with a 5 mm Satinato centre glass—delivers superior thermal insulation while diffusing light uniformly, eliminating harsh reflections and glare.

Thermal performance is independently certified by ift Rosenheim with a Ud coefficient of 0.85 W/m²K, placing it among the elite performers for exterior applications. The triple EPDM gasket system ensures comprehensive protection against water and air infiltration, even under extreme wind pressures. The 92 mm total system depth accommodates installation in diverse wall configurations, from traditional masonry to modern thermally insulated construction systems.

Dimensional flexibility extends to 1100×2300 mm for standard configurations and up to 1200×2500 mm for single-leaf units, providing adaptability for residential and commercial projects of varying scale. The door can be specified with multiple opening systems—hinged, semi-sliding, or pivot—tailored to spatial requirements and user preferences.

Ideal applications include contemporary residences, commercial buildings with stringent energy performance criteria, and renovation projects in climate zones requiring advanced thermal protection. Paired with premium hardwood flooring from our collection, this door creates a harmonious material transition between interior and exterior, reinforcing the overall architectural expression.

Ud 0.85 W/m²K (ift Rosenheim certified) indicates minimal heat loss through the door, meaning consistent interior comfort and significantly lower heating/cooling costs. This performance is achieved through the combination of the articulated 34 mm thermal break and the quadruple glazing system, ensuring elite thermal protection in harsh climates.

The door is constructed from aluminium profile at 3 mm thickness, with an overall system depth of 92 mm, integrating an articulated 34 mm thermal break. The glazing is quadruple with 44.1 triplex panes and a central Satinato decorative glass (5 mm), providing both discrete aesthetics and superior insulation. The finish can be customized to preference (painted, veneered, or laminated).

Yes, the door features 3 high-quality EPDM gaskets positioned at multiple levels, ensuring effective multi-point sealing. This system prevents water ingress and blocks cold air infiltration, essential for exterior doors in harsh climate conditions. EPDM is UV-resistant and handles temperature fluctuations, guaranteeing long-term durability.

The model offers standard dimensions up to 1100×2300 mm for standard systems, and for single-leaf (pivot) doors dimensions can reach 1200×2500 mm. Any custom configuration exceeding these standard limits is made to order with full adaptation to your space. We recommend consulting our design team to optimize proportions and opening mechanism suited to your masonry conditions.

The door is installed directly into the existing masonry opening, adapting to the 80 mm frame depth. The system is compatible with standard aluminium frames and modern masonry (brick, concrete, stone), as well as external thermal insulation systems (ETIC). Fixing is done with chemical or mechanical anchors; for optimal results, we recommend frame inspection and consultation with an installation specialist to ensure precise levelling and proper sealing.

Regular cleaning of the aluminium profile with water and a soft cloth keeps the finish intact; avoid abrasive chemical agents. EPDM gaskets require annual inspection and occasional lubrication with specific products to maintain optimal sealing. Opening mechanisms and hinges should be checked periodically for smooth operation. For painted or laminated finishes, light annual maintenance with soapy water and complete drying ensures durability over 20+ years.
