Aluminium exterior door L126-5 made to order

Aluminum exterior door with articulated thermal break and exceptional insulation performance (Ud=0.85 W/m²K). A 92 mm deep system featuring quadruple glazing for superior protection and comfort.

The L126-5 exterior door is a premium aluminum access solution engineered for properties demanding top-tier thermal performance and contemporary aesthetics. The 3 mm aluminum profile, combined with the system's total depth of 92 mm, delivers a rigid and durable structure capable of supporting advanced glazing without compromise.

Construction benefits from an articulated thermal break of 34 mm, eliminating cold bridges and significantly reducing heat transfer across the threshold. The glazing composition is quadruple—consisting of 44.1 mm triplex, 5 mm satin glass, and another 44.1 mm triplex layer—providing superior thermal resistance, acoustic dampening, and structural integrity. The Ud value of 0.85 W/m²K, certified by ift Rosenheim, positions this door in the highest category of energy performance for exterior access points.

Sealing is achieved through three strategically positioned EPDM gaskets, preventing air and water infiltration under severe weather conditions. This multi-layered approach ensures long-term durability with minimal maintenance demands. The frame depth of 80 mm allows elegant integration into masonry of any thickness, finished raw for customization to individual decor preferences.

Standard maximum dimensions of 1100×2300 mm extend to 1200×2500 mm for single-leaf versions, offering flexibility for projects with specific architectural requirements. The door suits contemporary and post-modern interiors, making it ideal for residences prioritizing energy efficiency and minimalist design. Aluminum permits diverse finishes and performs exceptionally in mixed climates.

Recommended for main entrances in modern homes, high-end residential buildings, and commercial spaces with stringent insulation standards. Pairs seamlessly with solid wood flooring, natural stone, or polished concrete, creating refined transitions between interior and exterior living.

The Ud=0.85 W/m²K coefficient (certified by ift Rosenheim) classifies this door in the premium thermal insulation category, reducing heat loss through the frame and glazing by approximately 30% versus standard systems. This translates directly to lower energy consumption and superior comfort in regions with variable climate conditions.

The 34 mm articulated thermal break physically separates the exterior from interior aluminium, blocking the thermal bridge and maintaining the internal surface temperature close to room temperature. This system ensures immediate tactile comfort and prevents condensation even under harsh winter conditions.

The quadruple configuration with 44.1 mm triplex glass (laminated, safe when broken) and centre Satinato glazing provides superior thermal and acoustic insulation, plus enhanced impact safety. Multiple layers absorb external vibrations and noise, reducing indoor sound levels and creating a security barrier that delays intrusion attempts.

Yes, the L126-5 profile allows for custom-made configurations. Standard dimensions 1100×2300 mm can be adjusted up to the maximum limit of 1200×2500 mm for a single leaf door. Customizations are made during the manufacturing phase with standard lead times of 4–6 weeks and no additional cost for minor dimension variations.

The multi-point sealing system with 3 EPDM gaskets (superior-grade synthetic elastomers) ensures a continuous barrier against water and draughts across the entire door perimeter. EPDM is UV-resistant and withstands extreme climate variations (from -40°C to +80°C), maintaining flexibility and adhesion throughout the door's entire service life.

The total 92 mm depth (80 mm frame + 92 mm leaf) combines a robust 3 mm aluminium profile with articulated thermal break and quadruple glazing, creating an extremely rigid structure resistant to deformation. This solidity ensures long-term stability, smooth operation, and durability for a minimum of 30 years without significant degradation.
