Aluminium exterior door L432 made to order

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.

The Ud value of 0.85 W/m²K represents top-tier performance for aluminium doors, certified by independent testing lab ift Rosenheim. This places the L432 in the premium category with energy efficiency comparable to Passivhaus standards. The thermal break features articulated 34 mm insulation and quadruple glazing for maximum performance.

The L432 features an aluminium core with a 3 mm profile thickness and a 92 mm leaf depth. The complete system (frame plus leaf) reaches 92 mm total depth with an 80 mm frame. Glazing is quadruple with Satinato treatment in the middle (44.1 triplex / 5mm Satinato / 44.1 triplex), ensuring superior acoustic and thermal insulation.

The L432 is available in standard configuration up to 1100×2300 mm or as a single leaf up to 1200×2500 mm. All dimensions are customizable to order to fit exactly your opening, whether standard or non-standard. The showroom team will assist with measurements and optimize dimensions for proper installation.

The sealing system features 3 EPDM multi-point gaskets ensuring airtightness around the entire perimeter. Hardware and hinges are premium-grade aluminium, guaranteeing long-term durability. For applications requiring anti-burglary classification, RC2/RC3 options are available with security cylinders and high-performance locks.

The L432 with its 80 mm frame is installed using standard fastening clips into the outer wall, compatible with brick, concrete, stone masonry, and modern insulated wall systems. The threshold can be supplied in standard or adjustable support version to accommodate minor level variations. For proper installation, we recommend consultation with our showroom team who will verify compatibility with your specific project.

The Satinato glazing offers an elegant matte finish and reduces reflections, creating a premium aesthetic. For maintenance, clean with water and neutral soap or dedicated glass solution, avoiding abrasive materials. Quadruple glazing requires no special treatment; EPDM gaskets should be inspected annually and lightly cleaned to maintain perfect sealing. Over time, aluminium profiles can be maintained with standard cleaning products without risk of degradation.
