Aluminium exterior door L963 made to order

Aluminum exterior door L963 with 92 mm profile depth and exceptional thermal performance (Ud 0.85 W/m²K). Quadruple glazing and triple-layer EPDM sealing ensure superior weather protection.

The L963 is a premium aluminum exterior door solution engineered for thermal performance and long-term durability. Its robust profile, with a total depth of 92 mm, delivers structural stability and a distinctive architectural presence at any entrance.

The system relies on a 3 mm aluminum shell with an articulated 34 mm thermal break that significantly reduces heat transfer. The quadruple glazing (44.1 triplex / 5 mm Satinato / 44.1 triplex) combines thermal insulation with natural light control and privacy. Triple EPDM sealing strips create a continuous weather and air infiltration barrier.

Certified thermal performance (Ud 0.85 W/m²K per ift Rosenheim testing) places this door in the high energy efficiency category, lowering heating and cooling consumption. The 92 mm leaf thickness and balanced 80 mm frame profile ensure smooth operation and high resistance to mechanical stress.

L963 accommodates standard dimensions up to 1100×2300 mm, with single-leaf configurations up to 1200×2500 mm, adaptable to most residential and commercial spaces. The system supports both sliding and hinged opening systems, allowing customization to suit preference and access requirements.

Ideal for main entrances in modern homes, office buildings, and high-end commercial spaces, L963 combines constructive reliability with discrete elegance. The Satinato glazing adds a note of sophistication, suitable for any contemporary or minimalist design concept.

Ud 0.85 W/m²K is superior thermal performance certified by ift Rosenheim, placing this door in the premium insulation category. With better insulation than standard doors, you'll reduce heat loss by up to 30%, matching a well-insulated wall's performance. The 92 mm depth and 34 mm articulated thermal break work together to minimize thermal bridging.

The quadruple thickness—formed by two 44.1 mm triplex layers with 5 mm Satinato glass between them—creates exceptional acoustic and security barriers. Each triplex layer uses laminated glass that dampens sound vibrations and resists impact; combined they offer substantial anti-break-in protection without sacrificing transparency. The acoustic response is particularly efficient against street noise, reducing it by 40+ dB.

1100×2300 mm is the standard dimension; if you need a larger door or a configuration custom-adapted to your masonry, the manufacturer offers extensive customization up to 1200×2500 mm for a single leaf. Each made-to-order piece is factory-fabricated entirely, ensuring that the frame seal and three-point sealing are optimized for your opening's exact geometry.

The 92 mm profile (80 mm frame plus 12 mm for sealing and finishing) adapts to standard aluminium, stainless steel, or timber frames, with lateral adjustment options to compensate for minor masonry variations. Installation requires a well-prepared opening with maximum ±10 mm deviation. The three-point EPDM sealing gaskets are applied to anchoring grooves, absorbing dimensional variations and ensuring an airtight closure across the entire surface.

The L963 aluminium requires light monthly cleaning with neutral soap and water; avoid abrasive materials that can damage the anodized finish. The EPDM gaskets require annual inspection to ensure they're not cracked or deteriorated; if affected, they're easily replaced without complete disassembly. For quadruple glazing, use only distilled water and mineral wax, avoiding aerosol cleaners that can leave alkaline deposits on laminated layers.

While specific RC2/RC3 classification is not explicitly listed, the combination of quadruple laminated glass (44.1 triplex on both sides), 3 mm aluminium profile, and multi-point sealing provides robust physical and acoustic defence against forced entry. The ift Rosenheim-certified profile and 92 mm depth place it in the premium resistance segment; for official RC2 or RC3 certification, consult the manufacturer about additional security hardware options.
