Aluminium exterior door L516 made to order

L516 aluminium exterior door with 92 mm system depth and quadruple glazing, delivering exceptional thermal performance at Ud 0.85 W/m²K. Contemporary profile with low-threshold design and triple-line sealing.

The L516 exterior aluminium door is a high-performance solution designed for residential and commercial projects requiring superior thermal insulation and contemporary aesthetics. With a 92 mm system depth and an articulated thermal break of 34 mm, the profile delivers optimal balance between structural rigidity and energy efficiency. Certified by ift Rosenheim, its Ud value of 0.85 W/m²K positions this system in the premium category of entrance solutions.

Construction employs 3 mm aluminium offering exceptional resistance to deformation and long-term durability in extreme climates. The quadruple glazing—two 44.1 triplex panes with intermediate Satinato glass—combines transparency, superior acoustic insulation, and UV protection. Triple-line EPDM sealing ensures reliable protection against water infiltration and air leakage, critical for exposed facades.

Thermal performance is underpinned by the continuous articulated thermal break running through the system depth, minimizing thermal bridging. This configuration reduces heat loss in winter months while providing optimal protection during warm seasons. Combined with high-grade EPDM gaskets, the door achieves notable sound insulation, reducing exterior noise levels by approximately 30–35 dB depending on conditions.

The system accommodates standard dimensions up to 1100×2300 mm with dual-leaf configuration or single-leaf up to 1200×2500 mm, offering architectural flexibility for large-scale facade projects. A low threshold facilitates accessibility while seamlessly integrating into minimalist modern interiors. System versatility permits customization of finishes and opening solutions: single-swing, double-swing, pivot, or sliding mechanisms.

As a primary entrance for premium residences, offices, or commercial spaces, the L516 seamlessly complements contemporary and industrial modern design vocabularies. Full compatibility with automated closing systems and installation on internal or external insulated structures ensures on-site implementation versatility.

With a Ud coefficient of 0.85 W/m²K (ift Rosenheim certified), the L516 exceeds requirements for near-zero energy buildings. Insulation is delivered by the quadruple glazing (44.1 triplex / 5mm Satinato) and a 34mm articulated thermal break that blocks heat transfer through the aluminium frame.

The L516 system accommodates standard dimensions up to 1100×2300 mm, and in single-leaf configuration up to 1200×2500 mm. For larger openings, multi-leaf configurations with central pivot are recommended, which distribute weight and allow spectacular architectural proportions without compromising rigidity.

The L516 door features multi-point sealing with three EPDM gaskets that provide protection against water and wind in severe driving rain conditions. The 92mm frame profile and 3mm aluminium structure guarantee high structural resistance; for additional anti-break-in protection, it can be equipped with RC2/RC3 hardware and security cylinder according to local requirements.

L516 is designed for external frame installation, with a frame depth of 80 mm and total system depth of 92 mm, requiring masonry of compatible thickness (minimum 120 mm, ideally 150+ mm). Installation is performed with surface mounting or cavity installation and requires a rigid base and proper sealing on three sides to prevent water infiltration and maximize thermal performance.

L516 can be finished in aluminium paint (standard), veneer or laminate, offering aesthetic flexibility for architectural integration. Finishes are maintained through periodic cleaning with water and neutral detergent; the paint coating is UV and weather resistant, and EPDM gaskets require annual inspection and possible replacement after 10-15 years of severe exposure.

L516 is equipped with quadruple glazing composed of 44.1 triplex / 5mm Satinato (frosted) / 44.1 triplex, delivering superior thermal and acoustic insulation. The triple layers (3+3+1 mm) absorb vibrations and reduce external noise transmission, while air spaces between panes are filled with inert gases for maximum thermal performance. The Satinato finish adds visual discretion and light diffusion.
