Aluminium exterior door L432 made to order

from2152.5 € + VAT

Aluminium entrance door with advanced thermal performance (Ud 0.85 W/m²K) and quadruple glazing. Engineered for premium residences requiring durability, energy efficiency, and contemporary aesthetics.

The L432 represents premium-tier aluminium exterior doors with robust profiling and integrated sealing systems for contemporary residences. Compact 92 mm system depth ensures seamless wall integration regardless of masonry thickness, without compromising thermal performance.

Professional-grade construction features 3 mm aluminium profile reinforced with articulated 34 mm thermal break, effectively eliminating cold bridging and reducing heat loss pathways. The quadruple-pane system—combining 44.1 mm triplex glass with satinized 5 mm intermediate pane and 44.1 mm triplex—delivers certified thermal transmittance (Ud 0.85 W/m²K, ift Rosenheim tested) alongside superior acoustic insulation. Triple EPDM gaskets provide persistent weather tightness across seasonal temperature fluctuations.

Energy performance stems from deliberately engineered construction for high-specification homes. A Ud value of 0.85 W/m²K positions this door in the maximum efficiency category, delivering measurable heating and cooling cost reductions over the building lifecycle. Single-leaf capacity up to 1200×2500 mm provides design flexibility for ambitious residential applications and generous openings.

The linear, contemporary profile integrates effortlessly with minimalist and traditional architectural languages. Variable sizing (standard up to 1100×2300 mm) and satinized glass for privacy without compromising natural light make L432 a versatile choice for main entries, living spaces, and openings demanding generous proportions.

This is the solution for owners prioritizing engineered German quality, certified durability, and high-end aesthetics. Compatible with floor heating systems, the door creates a secure and thermally intelligent transition between interior and exterior environments.
