Aluminium exterior door L150 made to order

Aluminium exterior door with 92 mm slim profile and quadruple glazing, delivering exceptional thermal efficiency (Ud 0.85 W/m²K) and contemporary facade aesthetics.

The L150 exterior door positions itself in the premium segment of aluminium solutions for primary entrances and modern residential facades. Its 92 mm profile combines visual slenderness with robust engineering, designed for generous openings and seamless architectural integration in contemporary projects. The system belongs to the high-performance door range, ideal for energy-efficient homes and commercial applications requiring demanding thermal standards.

Construction is anchored in 3 mm aluminium profile, meticulously finished with technical precision throughout. The profile incorporates a 34 mm articulated thermal break that interrupts thermal bridges and maintains isolation integrity across the full 92 mm depth. The quadruple glazing type (44.1 triplex / 5 mm Satinato / 44.1 triplex) delivers superior insulation, while triple EPDM gaskets ensure maximum sealing performance over extended service life.

Thermal performance is certified through ift Rosenheim testing, achieving a Ud coefficient of 0.85 W/m²K, positioning this solution among the most efficient aluminium doors available. Total system depth of 92 mm permits installation in existing frames with minimal adjustments, while maximum dimensions (1200×2500 mm for single leaves) provide substantial design flexibility. Triple EPDM gaskets and articulated thermal barrier guarantee long-term resistance to climate variation and mechanical wear.

Design accommodates broad architectural customization, with adaptable dimensions and leaf configurations to match specific functional needs. The system supports swing operation and can be configured for bespoke requirements. The compact profile creates clean lines around the opening, advantageous for minimalist-oriented interiors and facades.

This exterior door is recommended for energy-conscious residences, premium renovation projects where thermal insulation is paramount, and applications in demanding climatic zones. Compatibility with high-performance glazing and triple-seal systems makes it ideal for challenging weather conditions. Integration with timber flooring, paved concrete, or other natural materials creates architectural continuity in open-plan living spaces.

The Ud coefficient of 0.85 W/m²K certified by ift Rosenheim indicates exceptional thermal insulation—well above standard comfort levels for temperate climates. This translates into reduced heat loss through the door, lower heating costs, and superior thermal comfort during cold seasons.

The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) creates multiple air chambers that trap heat and reduce sound transmission. Each triplex layer also provides additional safety through impact resistance and controlled fragmentation—essential for a high-performance exterior door.

The 34 mm articulated thermal break physically separates the outer aluminium profile from the inner one, preventing direct heat conduction. This articulated system allows flexibility for thermal expansion and is critical to achieving the Ud coefficient of 0.85 W/m²K while ensuring structural stability and comfort.

The standard offering is up to 1100×2300 mm, but for single leafs you can request up to 1200×2500 mm. Any dimension beyond these limits requires technical consultation—contact the showroom to discuss projects with special requirements and custom solutions.

The door has a total thickness of 92 mm (leaf 92 mm, frame 80 mm) with a total system depth of 92 mm. For installation in existing frames, the wall depth must be verified—if there's a mismatch, adaptor strips or partial frame reconstruction may be needed.

The aluminium profile requires light annual cleaning with water and a soft cloth—aluminium resists oxidation and needs no additional painting. EPDM seals should be inspected every 2–3 years and cleaned of mineral deposits. The quadruple glazing requires no special maintenance, but avoid sudden thermal shocks.
