Aluminium exterior door L241 made to order

L241 exterior aluminum door with advanced thermal insulation and quadruple glazing. A 92mm profile engineered for exceptional performance and architectural distinction.

The L241 exterior door is a premium entry solution engineered for properties demanding exceptional thermal performance and architectural longevity. Constructed from high-grade aluminum with a 92mm profile, it merges the refined linearity of contemporary design with the technical rigor of European engineering standards. This model positions itself in the upper segment of the exterior door market—the definitive choice for landmark residential and cutting-edge commercial projects.

The system's foundation rests on a 3mm aluminum profile, dimensioned for maximum mechanical resilience and weather-resistant durability. The quadruple glazing—configured as 44.1 triplex / 5mm Satinato / 44.1 triplex—delivers exceptional thermal and acoustic insulation, while triple EPDM sealing ensures weathertightness across the lifecycle. The strategically articulated 34mm thermal break intercepts thermal bridges and reduces energy loss to near-optimal levels.

With a thermal coefficient Ud of 0.85 W/m²K (ift Rosenheim certified), this door meets Europe's most stringent insulation classifications. The 92mm total system depth—frame 80mm, leaf 92mm—integrates seamlessly into energy-conscious construction envelopes. The aluminum's inherent resistance to environmental stress and corrosion ensures decades of performance without degradation.

L241 accommodates dimensions up to 1200×2500mm for single leaves and 1100×2300mm for double-leaf configurations. The system supports swing, dual-swing, and pivot opening mechanisms, allowing flexible integration across diverse architectural contexts. Aluminum finishes—anodized, polished, or lacquered—and customizable functional elements ensure visual coherence with your building's identity.

This door excels as the primary entrance to corporate headquarters, luxury residences, and high-end retail environments, commanding architectural presence across minimalist, classical, and neo-European interior schemes. Pairing with natural stone, aged concrete, or weathered steel cladding amplifies its structural and aesthetic distinction.

The thermal coefficient Ud of 0.85 W/m²K, certified by ift Rosenheim, places this door in the high-performance category according to current European standards. Insulation is ensured by the 34 mm articulated thermal break and the quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex), which retains heat and prevents condensation on surfaces in extreme weather conditions.

The frame and leaf are fabricated from aluminium with 3 mm wall thickness and a total leaf thickness of 92 mm, with a frame depth of 80 mm. The 92 mm aluminium profile with 34 mm thermal break provides superior structural rigidity, corrosion resistance, and long-term thermal stability. This solution is ideal for prestigious entrances requiring extreme durability and minimal maintenance.

The door is equipped with 3 multi-point EPDM gaskets that ensure progressive sealing around the entire perimeter. The 92 mm system depth (with 80 mm frame) provides excellent drainage and ventilation capacity, preventing water accumulation at the door sill. The combination of high-quality elastic gaskets with aluminium profiles guarantees maximum protection against infiltration in heavy rain and strong wind conditions.

Standard sizing supports up to 1100×2300 mm, and for a single pivot leaf the maximum dimension is 1200×2500 mm. The door can be customized according to your project requirements and available space. For custom dimensions, we recommend a technical consultation to evaluate compatibility with existing frames and masonry.

Installation requires an approved frame and a masonry opening conforming to the door's dimensions. The total system depth of 92 mm must fit within available space, with the 80 mm frame properly positioned in the opening. The installation process involves anchoring the frame with fasteners, sealing with polyurethane foam, and meticulous finishing with proper protection. We recommend professional certified installation to ensure maximum thermal and acoustic performance.

High-quality aluminium requires minimal maintenance — regular cleaning with water and soap to maintain flawless appearance. EPDM gaskets should be inspected periodically and lubricated with specific lubricants to ensure optimal functionality. The door can be finished with aluminium paint, veneer, or laminate, each offering different aesthetics and corresponding resistance to weather conditions. Finishes provide both aesthetic and functional protection against UV and degradation over time.
