Aluminium exterior door L733 made to order

Aluminium exterior door L733, 92 mm profile, ift Rosenheim certified thermal performance Ud 0.85 W/m²K and quadruple glazing for exceptional climate protection.

The aluminium exterior door L733 proves its value in any residential or commercial context through solid construction and verified thermal performance. The series belongs to the category of aluminium doors with advanced thermal insulation, designed for clients seeking energy efficiency without sacrificing dimensional flexibility or discreet design. With a total profile of 92 mm and frame depth of 80 mm, it ensures façade compactness and structural rigidity necessary for larger openings.

Construction is based on 3 mm aluminium, a material guaranteeing long-term durability even in corrosive environments or with intense sun and water exposure. The articulated 34 mm thermal break effectively separates internal from external conditions, preventing thermal bridges and delivering a Ud coefficient of 0.85 W/m²K—a performance certified by ift Rosenheim and validated against strict European standards. Triple EPDM gaskets create complete sealing around the door perimeter, blocking water infiltration and air currents.

The quadruple glazing system (44.1 triplex / 5 mm Satinato / 5 mm / 44.1 triplex) delivers superior thermal insulation and appreciable acoustic protection, essential in urban zones or near traffic arteries. Laminated layers prevent accidental breakage and stop noise propagation. The 92 mm leaf and three-point sealing system form a protective barrier that maintains stable interior temperature regardless of external climatic conditions.

Dimensional flexibility is a key strength: standard configurations allow apertures up to 1100×2300 mm, while single-leaf versions reach 1200×2500 mm, opening varied possibilities for modern façades. The door adapts seamlessly to swing, sliding, or pivot opening systems depending on spatial and ergonomic requirements.

Suitable for passive houses, homes with high energy standards, and commercial buildings with strict climate requirements, the L733 pairs elegantly with minimalist interiors, concrete, light wood, or contemporary tile flooring. It is a door that prioritises functionality and thermal comfort without compromising design restraint.

This L733 door achieves Ud = 0.85 W/m²K, certified by ift Rosenheim, placing it among the most thermally efficient aluminium exterior doors available. This low value ensures minimal heat loss and delivers substantial energy savings for your home.

The glazing is quadruple: 44.1 triplex / 5mm Satinato / 44.1 triplex, a composition that combines acoustic protection with advanced thermal insulation. Triplex layers provide enhanced safety, with fragments remaining adhered in case of breakage, while Satinato glass ensures natural light diffusion without compromising thermal performance.

Standard maximum dimensions are 1100 × 2300 mm, while a single pivot leaf can reach up to 1200 × 2500 mm. This door accepts custom-made orders to match your specific project requirements, ensuring perfect integration regardless of your existing architecture.

The profile has a total depth of 92 mm, with a frame depth of 80 mm and a leaf thickness of 92 mm, while the exterior aluminium is 3 mm thick. The articulated 34 mm thermal break between the outer and inner profile prevents heat conduction, allowing the aluminium to remain corrosion-resistant without sacrificing insulating performance.

The door features 3 EPDM gaskets that provide multi-point sealing along the entire frame length. These gaskets are resistant to temperature fluctuations and UV exposure, offering a durable barrier against water and wind infiltration, even under extreme weather conditions.

With a frame depth of 80 mm, the L733 door installs into a standard opening and is compatible with wooden, MDF, or aluminium frames, depending on your desired interior finish. We recommend professional installation to ensure optimal sealing and precise alignment, especially for oversized openings or irregular masonry.
