Aluminium exterior door L260 made to order

L260 aluminium exterior door with advanced thermal performance Ud=0.85 W/m²K and articulated thermal break. Premium construction featuring quadruple glazing and three-layer EPDM sealing for exceptional weather resistance.

The L260 is a premium aluminium exterior door engineered for contemporary architecture with demanding thermal and structural requirements. Positioned as a high-performance solution, this model combines German-standard construction principles with advanced material technology. The L260 delivers reliable functionality across diverse climatic conditions whilst maintaining elegant proportions suited to modern residential and commercial facades.

The aluminium profile features a 3 mm gauge optimized for durability and thermal efficiency. The articulated thermal break of 34 mm effectively interrupts heat transmission pathways, working synergistically with a sophisticated quadruple glazing system. The glazing specification—comprising 44.1 mm triplex panes, 5 mm airspace, and Satinato interlayer glass—creates a high-performance barrier against environmental stress. A total system depth of 92 mm and a leaf thickness of 92 mm distribute mechanical loading uniformly, whilst triple EPDM gaskets provide airtight and watertight sealing throughout the frame perimeter.

With a certified thermal coefficient of Ud=0.85 W/m²K (ift Rosenheim testing), the L260 qualifies for energy-efficient building standards and delivers measurable reductions in heating and cooling demand. The multi-layer glazing system simultaneously provides acoustic insulation, a critical feature in urban or exposed environments. Structural resilience to wind load and thermal cycling ensures long-term performance without degradation.

Standard maximum dimensions of 1100×2300 mm and single-leaf capability up to 1200×2500 mm accommodate diverse architectural layouts and renovation scenarios. Aluminium finish options align with contemporary design palettes, from subtle naturals to bold statements. The door integrates seamlessly with motorized systems, smart home platforms, and security installations.

The L260 is ideally specified for premium residential projects, office buildings with strict thermal budgets, and commercial applications in challenging climates. Its compatibility with radiant heating systems and digital climate control makes it a strategic choice for net-zero or near-zero energy objectives.

Ud=0.85 W/m²K is an excellent value for external doors and indicates minimal heat loss. This keeps your home heating and cooling stable, significantly reducing energy consumption and monthly bills. Results are certified by ift Rosenheim, a guarantee of real performance.

Quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) offers superior thermal and acoustic insulation compared to standard solutions. Each layer of triplex glass absorbs vibrations and heat, guaranteeing interior peace and comfort, especially for homes in noisy urban areas or extreme climates.

The articulated thermal break of 34 mm is an insulating barrier that separates the interior aluminum from the exterior, preventing heat transfer between different environments. It creates a protective buffer that maintains constant interior temperature and reduces the need for excessive air conditioning, making it an A-class energy performance door.

Yes, for single-leaf doors, the maximum is 1200×2500 mm. For larger dimensions or special configurations (pairs, triple-leaf, side windows), I recommend contacting us directly with your space plans — we specialize in bespoke solutions and will find the perfect combination for your entrance.

The L260 system with a total depth of 92 mm and frame depth of 80 mm adapts easily to concrete, brick, or stone masonry. Recommendation: before installation, check wall thickness and edges to ensure proper multi-point sealing and secure mounting. We provide technical consultation for each project.

The L260 aluminum requires periodic cleaning with water and neutral soap; avoid aggressive chemicals that can damage the finish. EPDM seals should be inspected annually and lightly lubricated with neutral silicone to maintain flexibility. In areas with extreme climate or high pollution, I recommend annual protective polishing to extend lifespan.
