Aluminium exterior door L761 made to order

Aluminium exterior door L761 featuring exceptional thermal performance (Ud 0.85 W/m²K) and quadruple glazing for superior energy efficiency. Contemporary design built for durability and climate resilience.

The L761 aluminium exterior door is a premium access solution engineered for uncompromised thermal performance and durability. Available in standard sizes up to 1100×2300 mm and single-leaf variants up to 1200×2500 mm, this door adapts seamlessly to virtually any architectural opening. Its refined profile and clean lines position it as the definitive choice for contemporary residential and commercial properties.

Construction combines a 3 mm aluminium profile with a total system depth of 92 mm, reinforced by an articulated thermal break of 34 mm that eliminates thermal bridging. The quadruple glazing—44.1 triplex, 5 mm satin glass, and 44.1 triplex—delivers superior insulation and acoustic shielding. Triple EPDM gaskets maintain consistent sealing integrity across seasons, even under extreme wind and weather exposure.

Thermal performance certified by ift Rosenheim achieves a Ud coefficient of 0.85 W/m²K, placing this door in the highest efficiency class. This translates to minimal winter heat loss and robust summer solar control, reducing HVAC loads and lowering energy costs. The 92 mm overall thickness and deep profile profile also deliver exceptional sound insulation—critical for properties requiring acoustic comfort and privacy.

L761 supports diverse configurations—swing, sliding, and pivot—adapting to architectural preferences and functional requirements. Flexible dimensions enable seamless integration into modern facades, whether minimalist or urbane. Aluminium is fully recyclable and demands minimal maintenance, preserving impeccable appearance for decades.

This door suits primary entrances, terrace access, and in sliding configuration, large-span openings requiring unobstructed sightlines. It harmonizes beautifully with contemporary wall finishes, solid wood or mineral-effect flooring, and reinforces visual cohesion in modern apartments and homes. For commercial buildings, dimensional flexibility and mechanical robustness make it indispensable.

The Ud coefficient of 0.85 W/m²K (ift Rosenheim certified) places this door in the highest performance category for exterior applications. The combination of quadruple glazing and the articulated 34 mm thermal break ensures minimal energy loss, significantly reducing heating consumption compared to conventional doors.

The total system depth is 92 mm, with a frame depth of 80 mm and a leaf thickness of 92 mm. Installation in an existing frame depends on the structural capacity of the current frame — for optimal results and maximum air and water resistance, we recommend an adapted frame or complete replacement, installed according to European standards.

The system uses quadruple glazing: 44.1 Triplex / 5 mm Satinato / 44.1 Triplex. Multiple layers of laminated glass and varied thicknesses significantly reduce low-frequency and acoustic sound transmission, providing superior sound insulation for properties near busy roads or airports.

Standard maximum dimensions are 1100×2300 mm, and for a single leaf they can reach up to 1200×2500 mm. For non-standard openings, custom configurations are available — we recommend contacting our consultants with your opening measurements to assess feasibility and specify the optimal solution.

Sealing is achieved with 3-point EPDM gaskets that prevent water and air infiltration in extreme conditions. The system is tested and certified according to European standards for water and wind resistance, guaranteeing optimal protection even in harsh climates or direct storm exposure.

The main profile is 3 mm aluminium, a robust and durable choice for exterior use, resistant to corrosion and extreme weather conditions. Maintenance is minimal — periodic cleaning with water and neutral detergent, plus annual lubrication of gaskets and hardware keeps functionality and aesthetics intact long-term without significant effort.
