Aluminium exterior door L524 made to order

High-performance exterior aluminium door with 92 mm system depth and quadruple glazing—thermal efficiency Ud 0.85 W/m²K certified by ift Rosenheim. Contemporary profile engineered for sustained weather protection and comfort.

The L524 represents premium exterior aluminium engineering, designed for residential and commercial properties demanding high-performance thermal separation combined with contemporary architectural presence. The 92 mm system profile ensures visual balance and structural integrity across modern minimalist and transitional façades, without visual heaviness.

Construction leverages 3 mm aluminium thickness reinforced by an articulated 34 mm thermal break—a sophisticated strategy that interrupts heat conduction pathways and substantially reduces thermal bridging. Triple EPDM gasket sealing system delivers robust weather protection against water infiltration and wind pressure, while the aluminium surface treatment resists corrosion across varied climatic conditions and high-salinity environments. The 80 mm frame depth provides secure installation and long-term dimensional stability.

Thermal performance reaches Ud 0.85 W/m²K (ift Rosenheim certified)—positioning this door among premium energy-efficient solutions with measurable reductions in heating and cooling operational costs. The quadruple glazing configuration—44.1 triplex / 5 mm Satinato / 44.1 triplex—delivers exceptional acoustic insulation alongside thermal resistance, transforming the entrance threshold into an effective sound barrier against external noise pollution.

Standard dimensions accommodate openings up to 1100×2300 mm; single-leaf versions extend to 1200×2500 mm, providing design flexibility across diverse project scales. The primary opening system—traditional swing mechanism with premium-grade hardware—operates with consistent smoothness through repeated cycles without mechanical degradation.

L524 suits projects where thermal and acoustic performance are non-negotiable: urban residences, heritage properties undergoing energy-performance retrofit, or office pavilions with stringent climate control requirements. Natural or anodised aluminium finishes integrate harmoniously with natural stone cladding, decorative concrete, or premium composite flooring, reinforcing the entrance as both functional and architecturally refined.

The thermal coefficient Ud of 0.85 W/m²K (certified by ift Rosenheim) places this door in the premium thermal insulation category, exceeding current EU standards. This is achieved through the total system depth of 92 mm, quadruple glazing, and the articulated thermal break of 34 mm, which significantly reduce heat loss during cold seasons.

The structure is made of pure aluminium with a thickness of 3 mm on the door leaves and a profile depth of 92 mm. The frame has a depth of 80 mm and is combined with an articulated thermal break of 34 mm that separates warm from cold surfaces, maintaining mechanical rigidity and strength.

The glass is quadruple (four panes) with a configuration of 44.1 triplex exterior / 5 mm Satinato / 44.1 triplex interior. This complex composition ensures superior acoustic insulation and reduces outside noise, providing the quiet necessary for quality residential spaces. Triplex panes also offer increased mechanical strength.

Standard maximum dimensions are 1100×2300 mm, but for a single leaf the door can reach 1200×2500 mm, allowing adaptation to projects with high ceilings or open spaces. Any modification is made to order directly at the factory, ensuring a perfect fit with your existing frame and masonry.

The system uses 3 EPDM multi-point gaskets (one on the profile and two on the leaves), creating continuous and flexible sealing that adapts to thermal expansion. EPDM is resistant to UV and ozone, maintaining elasticity for 20+ years, effectively preventing rainwater and strong wind infiltration throughout the door's lifetime.

The 80 mm deep frame is mounted standard in the existing wall with mechanical fixation in masonry (brick, concrete). Due to the compact system dimensions, it is compatible with traditional frames and wall modernizations in existing residences. Installation requires precise leveling for optimal sealing and door opening mechanism operation.
