Aluminium exterior door L535 made to order

Aluminium exterior door with rigid 92 mm profile and advanced thermal insulation Ud 0.85 W/m²K. Quadruple glazing system for maximum structural support, comfort and energy efficiency.

The L535 is a premium solution for exterior access points that demand superior structural integrity, thermal insulation, and contemporary design. The 3 mm aluminium profile combined with a quadruple glazing system (44.1 triplex + 5 mm Satinato + 44.1 triplex) delivers exceptional thermal and acoustic performance in all climatic conditions. The premium engineering approach ensures seamless integration with modern façades and diverse architectural traditions.

The system construction adheres to stringent international quality standards. The total 92 mm depth, structural frame of 80 mm, and articulated thermal break of 34 mm ensure long-term stability with minimal heat transfer. Triple EPDM gaskets create reliable, durable sealing that protects against water and air infiltration. The door has been certified by ift Rosenheim, an independent laboratory specializing in thermal and structural performance testing.

The thermal coefficient Ud 0.85 W/m²K positions this door in the high-efficiency building category, significantly reducing heat loss in cold seasons and maintaining interior comfort. The quadruple glazing provides not only thermal insulation but also appreciable acoustic protection in noise-exposed areas. The aluminium profile's mechanical resistance guarantees durability against climate extremes and normal wear.

Design-wise, the L535 accommodates generous dimensions—up to 1100 × 2300 mm in standard configuration and 1200 × 2500 mm for single leaves—enabling flexible integration into ambitious architectural projects. The uniform depth and modern proportions facilitate seamless coordination with other façade elements and contemporary interior design. Surface finishes and system versatility permit customization to meet specific project requirements.

This exterior door is recommended for modern residences, mixed-use buildings, and commercial spaces with elevated comfort and aesthetic standards. The combination of durable materials, advanced insulation, and clean design suits both renovation and new construction. Investment in a door of this calibre reflects long-term benefits in reduced heating costs and sustained property value.

The Ud coefficient of 0.85 W/m²K, certified by ift Rosenheim, places this door in the top thermal insulation class. This performance level ensures minimal heat loss in winter and maintains interior comfort, significantly reducing heating costs. The articulated 34 mm thermal break and quadruple glazing system are the key components driving this exceptional energy performance.

The L535 door is built with a rigid 3 mm aluminium profile, offering an ideal combination of strength and light weight. The total system depth is 92 mm, with a frame depth of 80 mm, ensuring structural stability and long-term durability. The door leaf reaches 92 mm, maximizing insulation capacity and protection against external elements.

The door is equipped with a multi-point sealing system featuring 3 EPDM gaskets, which not only provides thermal insulation but also prevents air and water infiltration, contributing to structural security. The rigid 92 mm aluminium profile and reinforced door leaf ensure superior mechanical resistance to force. The locking mechanism and hardware are sized to withstand the weight and daily stress of an exterior opening, guaranteeing functionality and safety for years to come.

The L535 door is available in standard sizes up to 1100×2300 mm for classic configurations. For a single hinged leaf, dimensions up to 1200×2500 mm can be achieved. Any size outside these limits or specific design requirements can be discussed with our showroom team, who will evaluate the feasibility of customization in accordance with technical and structural requirements.

The door features quadruple glazing — 44.1 triplex / 5mm Satinato / 44.1 Triplex, an advanced configuration combining laminated glass with protective film and special spacers for superior sound insulation. This combination significantly reduces external noise (traffic, wind) while providing additional impact protection. The door profile with thermal break and multi-point gaskets further enhance acoustic insulation, creating a quiet and comfortable interior environment.

The L535 door, with a frame depth of 80 mm and total system depth of 92 mm, is installed in standard masonry frames or structures with thermal insulation. Compatibility with different wall types (brick, concrete, stone) depends on proper opening and frame preparation. Installation requires strict adherence to plumb and level, adequate polyurethane foam sealing, and elastic gaskets to ensure optimal thermal and acoustic performance. It is recommended to consult with showroom specialists to validate compatibility with your structure.
