Aluminium exterior door L300 made to order

Aluminium entry door with advanced thermal insulation (Ud=0.85 W/m²K) and triple EPDM sealing. Engineered for durability and weather protection with solid 92 mm system depth.

The L300 aluminium entry door is a premium solution engineered for main access points requiring superior thermal performance and structural integrity. Built with high-grade aluminium and certified sealing systems, it represents the benchmark for contemporary residential and commercial projects demanding long-term reliability and energy efficiency.

The system features a comprehensive 92 mm total depth with an 80 mm frame profile, ensuring exceptional structural stability and resistance to warping under extreme conditions. The 3 mm aluminium profile incorporates an articulated 34 mm thermal break that significantly reduces heat transfer and minimizes thermal bridging. The quadruple glazing configuration—44.1 mm triplex + 5 mm Satinato glass + 44.1 mm triplex—delivers dual benefits of superior thermal insulation and acoustic dampening. Three EPDM gaskets provide absolute weather tightness across all climatic conditions.

With a thermal transmittance (Ud) of 0.85 W/m²K, independently certified by ift Rosenheim, this door meets Passivhaus standards for exterior doors. This specification translates to consistent interior comfort, measurable reductions in heating and cooling costs, and compliance with contemporary European energy regulations.

The flexible geometry accommodates standard dimensions up to 1100×2300 mm or single-leaf configurations reaching 1200×2500 mm, adapting seamlessly to diverse architectural requirements. The swing-hinged opening mechanism is ergonomically refined and maintenance-free, while finish customization aligns with interior design preferences.

Ideal for contemporary villas, residential properties, commercial access points, and any project demanding premium entrance doors. Fully compatible with radiant floor heating systems and integrates cohesively with professional-grade aluminium fenestration.

The Ud coefficient of 0.85 W/m²K (certified by ift Rosenheim) places this door in the premium thermal insulation category, exceeding standard European requirements for exterior doors. This performance level is achieved through the sitemat profile combined with a 34 mm articulated thermal break and quadruple glazing with special treatment.

For standard double-leaf opening, maximum dimensions are 1100 × 2300 mm, and for a single pivoting leaf up to 1200 × 2500 mm. Each order is custom-made to your project specifications and frame dimensions — tolerances are precisely adjusted for your masonry structure for flawless installation.

The structure is aluminum with sitemat profile, 3 mm thickness on leaves and 80 mm in frame channels, assembled with a 34 mm articulated thermal break system. Glazing is quadruple — 44.1 triplex / 5 mm Satinato / 44.1 triplex — providing mechanical strength and continuous thermal insulation. The aluminum is treated for corrosion resistance in harsh outdoor conditions.

The door is equipped with 3 EPDM gaskets (ethylene-propylene-diene), forming multi-point sealing around the entire perimeter. This triple configuration ensures complete impermeability to water and air, even in conditions of heavy wind and rain. EPDM remains flexible and inert over time, unaffected by UV or thermal fluctuations.

The total system depth is 92 mm (80 mm frame + 12 mm into masonry). Installation is performed in existing frames with precise tolerance adjustment, or for optimal results, in new custom frames. Compatibility with various masonry types (brick, concrete, stone) is ensured through flexible anchoring methods; consulting a qualified installer for accurate measurements and planning is recommended.

The treated aluminum from which the door is constructed naturally resists corrosion, but periodic cleaning with water and neutral detergent is recommended to prevent pollutant accumulation. EPDM gaskets should be inspected and cleaned annually to maintain optimal sealing. In areas with salt spray or industrial pollution, cleaning frequency should be increased. Any scratches in the finish should be repaired promptly to prevent oxidation.
