Aluminium exterior door L741 made to order

Aluminium entrance door with 92 mm structural depth and thermal coefficient Ud 0.85 W/m²K. Quadruple glazing and triple EPDM sealing for superior weather resistance.

The L741 model delivers a premium entrance solution engineered for properties demanding superior thermal and acoustic performance. The 3 mm aluminium profile, paired with an 80 mm frame depth and 92 mm leaf structure, provides exceptional rigidity and long-term dimensional stability. The articulated 34 mm thermal break interrupts cold bridging and eliminates condensation risk in winter conditions.

The quadruple glazing system—comprising 44.1 triplex outer panes separated by a 5 mm satinized interlayer and a 44.1 triplex inner pane—delivers outstanding sound insulation and thermal retention. Triple EPDM gaskets positioned along the entire perimeter ensure continuous protection against rain, wind, and air infiltration. The certified thermal transmittance Ud of 0.85 W/m²K (ift Rosenheim) places this door at the forefront of contemporary energy standards.

Standard dimensions reach 1100×2300 mm, with single-leaf configurations extending to 1200×2500 mm, accommodating diverse architectural openings from residential entrances to commercial passages. The aluminium profile supports extended color palettes and custom finishes, seamlessly integrating with both minimalist contemporary and traditional design languages.

Ideally suited for residential properties in continental and coastal climates, corporate offices prioritizing operational efficiency, and prestige locations where durability and refined aesthetics are paramount. Proper integration with perimeter insulation and compatible cladding systems maximizes the thermal performance of the building envelope.

The thermal coefficient is 0.85 W/m²K, certified by ift Rosenheim laboratory, placing it in the premium insulation category. This ensures exceptional heat retention, essential for harsh climates, and compliance with EU energy efficiency standards. The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) and articulated 34 mm thermal break deliver the stated performance.

The structural profile is aluminum, 3 mm thick, with an articulated thermal break that prevents cold transfer. Total system depth is 92 mm (frame profile 80 mm, leaf 92 mm), ensuring structural rigidity and stability. The aluminum frame is treated for corrosion resistance, ideal for intense sun exposure and harsh weather conditions.

The door features 3 EPDM multi-point gaskets that provide enhanced sealing and robust acoustic insulation. The 92 mm leaf thickness, combined with thick quadruple glazing and optimized internal spaces, dissipate sound energy and reduce external noise transmission. The complete sealing system prevents water and wind infiltration under extreme conditions.

Standard maximum dimensions are 1100×2300 mm, with single leaf configurations reaching up to 1200×2500 mm. Custom dimensions are available to order to fit any specific architectural configuration. Our specialists can precisely size the door to match your opening geometry and existing frame mounting requirements.

The 80 mm aluminum frame is mounted on standard frames or directly into masonry using mechanical fastening systems. The profiles feature dedicated channels for anchor points and elastomer seals, adaptable to different wall thicknesses and materials (brick, concrete, stone). Installation requires precise alignment and perimeter sealing with silicone for optimal thermal and acoustic performance.

Aluminum profiles require periodic cleaning with clean water and neutral detergent to remove atmospheric deposits. EPDM gaskets should be inspected annually and lightly lubricated with silicone if friction appears. The aluminum lacquer or chosen finish requires annual inspection for micro-cracks or deterioration, with local touch-ups if needed, to maintain long-term thermal integrity.
