Aluminium exterior door L170 made to order

Aluminum exterior door with advanced thermal insulation and quadruple glazing for superior performance. A modern, robust system designed for residential and commercial spaces seeking energy efficiency.

The L170 model represents the premium solution for exterior access in residential and commercial spaces, engineered to rigorous European standards. The 3 mm aluminum profile combines with an articulated thermal break of 34 mm, creating a total system depth of 92 mm that ensures structural stability and long-term durability.

The system's construction is built on thermal break technology, essential for variable climates. The quadruple glazing — configured as 44.1 triplex + 5 mm Satinato glass + 44.1 triplex — delivers exceptional acoustic and thermal insulation. Triple EPDM gaskets ensure perfect weather tightness against air and water infiltration, even under extreme wind and precipitation conditions.

The thermal coefficient Ud of 0.85 W/m²K, certified by ift Rosenheim, places this door in the superior energy class category. This means excellent heat retention in cold seasons and effective protection against solar radiation in summer. The system accommodates standard dimensions up to 1100×2300 mm and single-leaf variants up to 1200×2500 mm, adaptable to most openings.

Customization includes RAL finish and color options, allowing seamless integration into any façade concept. The system is compatible with multiple opening mechanisms — hinged, sliding, or pivot — offering design flexibility for diverse applications.

Recommended for modern properties requiring the balance between weather resistance, thermal-acoustic insulation, and clean aluminum profile aesthetics. Ideal when paired with structural glazing systems, living walls, or exposed concrete facades. A durable investment in thermal and acoustic comfort.

With a thermal coefficient Ud of 0.85 W/m²K (ift Rosenheim certified), this door delivers superior insulation performance. The quadruple glazing with triple-laminated glass and satin film ensures maximum heat retention in winter and solar protection in summer. The 92 mm total system depth combined with the 34 mm articulated thermal break delivers consistent performance aligned with European building standards.

The door is constructed from aluminium profile with 3 mm thickness, featuring a total leaf depth of 92 mm and frame depth of 80 mm. The profile incorporates a 34 mm articulated thermal break that separates the interior and exterior zones, preventing thermal bridging. The glazing consists of four layers: 44.1 mm triplex / 5 mm Satinato film / 44.1 mm triplex, with three EPDM gaskets providing multi-point sealing against water and air infiltration.

Standard dimensions are available up to 1100×2300 mm, while single-leaf configurations can reach up to 1200×2500 mm. All aluminium doors are custom-manufactured to your specific spatial requirements. We recommend consulting with our showroom specialist to verify compatibility with existing frames and determine the optimal solution based on your building's orientation and volume.

The quadruple laminated glazing and three-point EPDM sealing system provide substantial sound insulation. The thermal mass of the 92 mm aluminium structure, combined with the 5 mm satin film in the glazing, functions as a passive acoustic barrier. For extreme acoustic performance (Rw > 40 dB), we recommend consultation with our specialist regarding supplementary installation treatments and frame integration.

The aluminium profile with 80 mm frame depth installs into standard openings per DIN and European building codes. Compatibility depends on wall thickness (ceramic, concrete, brick) and frame type (metal, PVC, wood). The 92 mm system allows optimal integration with the building's thermal envelope. Installation requires plumb and level verification, polyurethane foam sealing, and mechanical fixing. We recommend certified installer services to guarantee thermal performance and acoustic integrity.

Aluminium requires periodic cleaning with lukewarm water and neutral detergent to maintain appearance. EPDM gaskets should be inspected annually and lubricated with neutral silicone if drying occurs. The frame drainage system must be kept clear of debris. For finishes, aluminium profiles can be powder-coated in custom RAL colours (matte, semi-gloss, gloss), anodised in Alodine catalogue shades, or finished with UV-resistant decorative films. Any damage should be repaired by authorised specialists to preserve thermal integrity.
