Aluminium exterior door L917 made to order

Aluminium exterior door L917 with superior thermal performance and quadruple glazing. 92 mm profile with articulated 34 mm thermal break for maximum efficiency in demanding climates.

The L917 is a high-performance exterior door solution engineered from aluminium with a 92 mm structural profile. It positions itself in the premium segment of exterior access systems, designed for residential and commercial buildings where energy efficiency and refined aesthetics are paramount.

The profile incorporates an articulated 34 mm thermal break that efficiently interrupts heat transfer between inside and outside. The aluminium section measures 3 mm thickness, with the complete system reaching 92 mm depth, ensuring structural rigidity and long-term stability. Triple EPDM seals provide optimal weather-tightness against wind and water infiltration, eliminating unwanted air leakage.

The quadruple glazing system—44.1 triplex / 5 mm Satinato / 44.1 triplex—delivers exceptional thermal insulation with a Ud coefficient of 0.85 W/m²K (ift Rosenheim certified). This translates to minimal heat loss and superior comfort throughout the year. Triple lamination on each layer ensures enhanced mechanical resistance, protecting against impact damage and improving security performance.

L917 is available in standard dimensions up to 1100×2300 mm, with custom single-leaf configurations extending to 1200×2500 mm. The system accommodates various opening configurations—hinged, sliding, or hybrid arrangements—adapting to specific architectural requirements. Aluminium finishing can be tailored to match design preferences and integrate seamlessly into any context.

This door is ideal for projects with stringent energy standards, near-passive or Passivhaus renovations, and properties where thermal performance and durability are non-negotiable. It integrates perfectly with radiant heating systems and comprehensive energy efficiency strategies.

The L917 achieves a Ud coefficient of 0.85 W/m²K, certified by the ift Rosenheim institute, placing it among the top performers for thermal efficiency in premium exterior doors. The 34 mm articulated thermal break combats extreme weather conditions and significantly reduces heat loss, ensuring superior comfort year-round.

The L917 features an aluminium profile with 3 mm thickness, offering a total system depth of 92 mm and leaf thickness of 92 mm, ensuring stability and durability. The construction supports premium finishes (painted, veneered, laminated) tailored to any architectural style, with complete customization based on design requirements.

The L917 is equipped with quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex), a premium configuration delivering superior thermal and acoustic insulation. The thickness and laminated structure significantly reduce external noise, creating a quiet and energy-efficient interior environment.

The L917 is available in standard sizes up to 1100×2300 mm and can be manufactured as a single leaf with maximum dimensions of 1200×2500 mm. All dimensions are customizable to order, allowing perfect fit for any architectural opening, whether residential or commercial.

The L917 uses 3 high-quality EPDM gaskets for robust multi-point sealing, ensuring complete impermeability to water and wind. The closing system combines premium hardware and concealed hinges, guaranteeing smooth opening and quiet operation, ideal for spaces with high security and comfort requirements.

The L917, with a frame depth of 80 mm and total system depth of 92 mm, installs easily in standard and custom aluminium, wood, or MDF frames. The modular system adapts to various masonry and construction types, with installation following professional mounting standards to ensure long-term sealing and durability.
