The L410 exterior door is a premium access solution engineered for clients demanding exceptional energy performance. This contemporary aluminium model, crafted with 3 mm profile thickness, integrates seamlessly into modern minimalist façades, creating a refined and understated entrance presence.
The system is built on a total depth of 92 mm with an 80 mm frame and matching leaf dimension, ensuring structural rigidity and long-term stability. The articulated thermal break of 34 mm is the critical element that dramatically reduces heat transfer through the door leaf. Triple EPDM gasket sealing provides comprehensive protection against air and water infiltration, guaranteeing lasting weathertightness and reliability.
The quadruple glazing configuration—44.1 triplex / 5mm Satinato / 44.1 triplex—delivers a thermal coefficient of Ud 0.85 W/m²K, independently verified by ift Rosenheim. This performance aligns with the most stringent European energy efficiency standards. The acoustic insulation is inherently substantial due to the glazing mass and system density, creating a quiet interior environment.
Dimensional flexibility ranges from 1100×2300 mm as standard up to 1200×2500 mm for single-leaf configurations, allowing adaptation to diverse architectural openings without compromise. Installation integrates smoothly with standard aluminium profiling systems.
Ideally suited for contemporary residences, premium commercial buildings, and high-end refurbishment projects, the L410 creates controlled separation between interior comfort and exterior conditions while maintaining thermal and acoustic performance. It pairs elegantly with minimalist flooring and anodised aluminium finishes in neutral tones.
