Aluminium exterior door L986 made to order

L986 aluminum exterior door with exceptional thermal insulation and quadruple glazing—a high-performance façade solution for contemporary residential and commercial projects. Advanced 92 mm system depth with articulated thermal break ensures lasting durability and comfort.

The L986 is a premium exterior access solution engineered with robust aluminum profile and an advanced insulation system. The profile features a total depth of 92 mm and frame depth of 80 mm, dimensions that ensure structural stability and refined finish. Certified by ift Rosenheim, the thermal transmission coefficient Ud = 0.85 W/m²K positions this door in the high-performance energy category—essential for contemporary building standards.

Construction combines 3 mm aluminum with an articulated thermal break of 34 mm, significantly reducing heat loss. Three-layer EPDM gaskets provide superior airtightness against water and wind infiltration. The quadruple glazing system—44.1 mm triplex + 5 mm satin glass + 44.1 mm triplex—delivers exceptional thermal and acoustic insulation, UV protection, and mechanical resistance. The leaf thickness of 92 mm aligns with system depth, guaranteeing perfect sealing.

Performance exceeds current European standards. Ud values confirm compliance with EU energy-efficiency regulations, translating to reduced heating and cooling costs over the door's service life. Quadruple glazing not only insulates thermally but also dampens external noise—critical in dense urban environments. Aluminum and EPDM gaskets resist corrosion, weathering, and UV degradation, maintaining aesthetic and functional integrity for decades.

L986 accommodates standard dimensions up to 1100 × 2300 mm, or upon request up to 1200 × 2500 mm for single-leaf configurations. Dimensional flexibility enables integration into diverse architectural openings—from residential to commercial and administrative projects. The system adapts seamlessly to various operating modes: hinged, sliding, or pivot—depending on design and functional requirements.

Ideal for primary entrances with north or east exposure, bioclimatic buildings, and projects prioritizing energy efficiency. Pairs beautifully with natural laminate flooring or neutral wall colors, creating fluid transitions between interior and exterior spaces. Initial investment is recovered quickly through energy savings and enhanced property value.

The Ud coefficient of 0.85 W/m²K is excellent performance for an exterior aluminium door, certified by ift Rosenheim (the German reference institute). This means minimal heat loss, increased indoor comfort and significantly reduced heating costs. The 92 mm profile with articulated thermal break of 34 mm and the quadruple glazing are responsible for this exceptional insulation.

The L986 quadruple glazing consists of: 44.1 triplex (protective outer pane) + 5 mm Satinato (insulating spacer) + 44.1 triplex (insulating core). This configuration provides superior thermal and acoustic insulation, better UV protection and maximum comfort. Standard double glazing cannot match this thermal performance and security.

The L986 door is customizable — you're not limited to fixed sizes. With standard configuration, the limits are 1100×2300 mm, but for a single leaf you can request up to 1200×2500 mm. If you have different requirements, custom sizing is possible — contact the showroom team to dimension it perfectly for your space.

Sealing is achieved through 3 high-density EPDM gaskets positioned at multiple points on the door frame, eliminating air drafts and rattling. This configuration combined with quadruple glazing and articulated thermal break significantly reduces outside noise — ideal for urban areas or near traffic. Acoustic performance also depends on professional installation, which we strongly recommend.

The 92 mm system is compatible with standard aluminium and steel frames. The door frame (80 mm) is anchored with screws into the masonry, and the side walls must be prepared accordingly. Installation requires professionalism — we recommend installation by the supplier or certified specialist to guarantee proper sealing. For specific details about compatibility with your masonry type — brick, concrete, etc. — please discuss with the showroom team.

Aluminium L986 is durable and corrosion-resistant, requiring only periodic cleaning with water and mild detergent — avoid acids or hard brushes. The quadruple glazing cleans like standard glass, with water and soap. EPDM gaskets require annual inspection to ensure they haven't deteriorated; if minor cracks appear, they can be easily replaced. In areas with severe salt or pollution exposure, we recommend more frequent cleaning.
