Aluminium exterior door L990 made to order

Aluminium exterior door with 92 mm system depth and exceptional thermal insulation (Ud=0.85 W/m²K). Quadruple glazing with specialist finishing for maximum protection and lasting comfort.

The L990 model represents a premium exterior access solution, engineered in structural aluminium with a 92 mm system profile. This robust construction delivers elegant architectural integration and exceptional stability, suitable for both contemporary residences and commercial applications demanding high performance standards. The 3 mm aluminium profile, combined with an articulated thermal break of 34 mm, ensures long-term durability and energy efficiency.

Thermal insulation is a defining feature, with a Ud coefficient of 0.85 W/m²K (certified ift Rosenheim), positioning this door in the upper segment of exterior solutions. The glazing is a rare quadruple specification — 44.1 triplex / 5mm Satinato / 44.1 Triplex — combining acoustic protection with resistance to external stresses. The 3-EPDM gasket sealing system provides comprehensive protection against water and air infiltration.

Performance has been validated through ift standard testing, demonstrating resistance to wind pressure and extreme thermal cycles. The profile accommodates generous dimensions — up to 1100×2300 mm in standard configuration, or 1200×2500 mm for single leaves — offering flexibility in entrance and exit design. The compact 92 mm total depth minimises impact on wall thickness.

With options for swing or sliding systems, L990 adapts to architectural preferences and traffic flow requirements. Aluminium finishing allows chromatic personalisation, from neutral to expressive tones, integrable into any exterior design concept.

This door is recommended for primary entrances with northern exposure, ventilated facades, or spaces requiring high-level thermal and acoustic insulation. The combination of structural stability, thermal performance, and design flexibility positions it as a reference choice for demanding residential and commercial projects.

With a Ud value of 0.85 W/m²K (certified by ift Rosenheim), this door ranks among the highest-performing exterior doors in the premium segment. This result is achieved through the 92 mm profile depth, articulated 34 mm thermal break, and specialized quadruple glazing, easily exceeding current European standards.

The 92 mm leaf is built with solid 3 mm aluminium thickness, featuring an internal rigid structure that ensures long-term stability. The painted aluminium finish is engineered for UV and weather resistance; with proper annual maintenance (cleaning and protective treatment), durability extends beyond 20 years without significant degradation.

The system uses 3 EPDM gaskets strategically positioned on multiple levels—frame and leaf—creating multi-point sealing. EPDM is elastic and resistant to extreme temperature fluctuations, ensuring continuous protection against water infiltration and air leakage. The 92 mm frame width and leaf thickness support this airtight performance without compromise.

Standard dimensions reach 1100×2300 mm, with single-leaf options extending to 1200×2500 mm. For customization beyond these limits or non-standard configurations, the showroom service provides technical consulting and custom orders based on masonry and opening parameters. We recommend precise space measurement and direct contact with our team to optimize your solution.

The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) combines lamination with air gaps for superior sound and thermal insulation. The 44.1 mm triplex (3+3+1.5 mm laminated) offers impact resistance and break-in protection, making it a secure choice for exterior doors in urban areas. The Satinato finish also adds subtle aesthetic appeal while maintaining safety functionality.

Installation requires frames sized to 92 mm (total system depth) and proper anchoring to bearing masonry. The 80 mm frame depth accommodates various construction types—concrete, brick, stone. For optimal thermal performance, we recommend complete sealing of gaps and additional insulation between frame and masonry. Installation and certification must follow European technical standards EN 12208.
