Aluminium exterior door L946 made to order

Aluminium exterior door with slender profile and superior thermal insulation (Ud 0.85 W/m²K). Robust construction featuring quadruple glazing and 34 mm articulated thermal break, designed for contemporary buildings.

The L946 is an aluminium exterior door solution that combines contemporary line refinement with high thermal performance. With a 92 mm system depth and 34 mm articulated thermal break, it represents the choice for projects demanding premium insulation and durability standards. The 3 mm aluminium thickness ensures structural rigidity and long-term deformation resistance.

The triple EPDM gasket sealing system guarantees effective protection against water infiltration and air leakage. The quadruple glazing system, composed of 44.1 mm triplex layers with 5 mm Satinato glass interlayer, delivers both thermal insulation and controlled visual diffusion. The Ud thermal transmittance coefficient of 0.85 W/m²K (certified by ift Rosenheim) confirms peak performance in heat retention.

The modular design permits configurations at standard dimensions up to 1100×2300 mm, with single-leaf options extending to 1200×2500 mm. The 80 mm frame depth provides optimal space for installation and security fastening. This exterior door integrates seamlessly into energy-conscious buildings where thermal efficiency and interior comfort are paramount.

L946 is recommended for contemporary residential projects, NZEB-standard office buildings and renovation schemes requiring compliance with strict European regulations. The combination of aluminium's refined lines and technical performance places it in the premium segment of modern exterior doors.

The quadruple-glazed composition of 44.1 triplex/5mm Satinato/44.1 triplex delivers superior thermal and acoustic insulation, significantly reducing heat loss and external noise transmission. Combined with the Ud coefficient of 0.85 W/m²K, this configuration positions the door among the most energy-efficient solutions for contemporary homes.

The articulated thermal break of 34 mm creates an insulation barrier between the exterior aluminium profile and the inner structure, preventing thermal energy transfer. This substantial insulation layer, combined with the 3-level EPDM multi-point sealing, ensures that heat stays indoors in winter and conditioned air remains inside during summer.

Standard maximum dimensions are 1100×2300 mm, and for a single leaf configuration, the door can extend up to 1200×2500 mm, providing flexibility for larger openings. We accept customisations within these ranges for each order to perfectly match your project's specific dimensions and proportions.

Yes, the 3 mm thickness is engineered for a slim profile without compromising mechanical strength. Combined with the leaf thickness of 92 mm and the articulated 34 mm thermal break, the structure ensures long-term rigidity and durability. The recyclable aluminium profile reduces the door's weight and simplifies installation while maintaining resistance to wind loads and external forces.

The door is installed in the aluminium frame with a depth of 80 mm, which mounts into standard brickwork or concrete/timber structures. The mounting system is compatible with virtually all modern masonry types and ensures perfect sealing through rigid contact between the profile and wall. Installation requires precise alignment and anchoring with fixing brackets; we recommend consulting a professional to ensure optimal sealing and thermal performance.

The aluminium profile requires periodic cleaning with neutral soap and water to maintain appearance and sealing performance; the glazing is cleaned like any standard window. The 3-level EPDM sealing is durable and UV-resistant, but annual inspection is recommended to verify gasket integrity. The painted finish on the profile is weather-resistant and requires no additional treatment during the door's normal lifespan, with minimal maintenance.
