Aluminium exterior door L290 made to order

Aluminum exterior door L290 with advanced thermal insulation (Ud = 0.85 W/m²K) and quadruple glazing. Robust system for main entrances featuring 92 mm profile depth and triple EPDM sealing.

The L290 exterior door represents premium entrance solutions where thermal performance meets architectural presence. With a total system depth of 92 mm and frame profile of 80 mm, it delivers distinctive visual weight and structural integrity that endures. The 3 mm aluminum thickness provides lasting resilience against weather and operational stress.

The articulated 34 mm thermal break ensures exceptional energy efficiency—certified by ift Rosenheim laboratories at Ud = 0.85 W/m²K, a benchmark of premium performance. Quadruple glazing (44.1 triplex / 5 mm satin / 44.1 triplex) creates a thermal and acoustic barrier of excellence, while triple EPDM gasket sealing provides impeccable protection against water and air infiltration across all operational cycles.

The system accommodates standard dimensions up to 1100 × 2300 mm, with single-leaf configurations reaching 1200 × 2500 mm, offering flexibility across diverse project scales. Modular construction enables personalization without compromising structural rigidity or performance consistency.

This door is conceived for spaces demanding both architectural refinement and superior insulation—main entrances in contemporary buildings, high-end residential projects, constructions meeting advanced energy standards. Compatibility with various opening systems and customization capacity make it equally suitable for renovations and new builds.

Raw aluminum permits diverse finishing approaches—anodizing, structured lacquering, or RAL color applications—for seamless integration into any architectural vocabulary, from contemporary minimalism to sophisticated simplicity.

The thermal coefficient Ud of 0.85 W/m²K places the L290 in the premium insulation category, certified through ift Rosenheim testing. This value is significantly better than the market average for aluminium doors and ensures superior energy efficiency throughout its lifespan, with direct impact on heating and cooling costs.

The L290 integrates an articulated thermal break of 34 mm, which separates the exterior profile from the interior and prevents energy transfer. Combined with the quadruple glazing (44.1 triplex + 5mm Satinato + 44.1 triplex) and three EPDM gaskets, it creates a highly efficient insulation barrier across the full system depth of 92 mm.

The L290 door uses three EPDM gaskets distributed strategically on the 80 mm frame, ensuring continuous sealing across the entire perimeter. This triple sealing system effectively eliminates water and wind infiltration, essential for interior protection in extreme weather conditions and maintains thermal performance regardless of season.

The L290 offers sizing flexibility with standard options up to 1100×2300 mm and custom order capability with single leaves up to 1200×2500 mm. We recommend precise measurement of the opening and consultation with the showroom team to verify existing frame compatibility and ensure correct installation in the wall.

Installing the L290 requires an opening sized to standard or custom specifications, with an 80 mm frame adapted to wall thickness. Installation requires anchoring with pins or dowels in solid masonry (concrete, solid brick), perimeter sealing with silicone, and level and plumb verification. We recommend professional assistance to ensure thermal insulation integrity and sealing system performance.

The L290 is constructed from 3 mm aluminium with an insulating core, ensuring superior durability and structural stability. Aluminium is corrosion-resistant, requires no periodic repainting, and is easily maintained with water and neutral detergent cleaning. EPDM gaskets should be inspected annually and lubricated with silicone if needed to maintain long-term sealing performance.
