Aluminium exterior door L335-1 made to order

High-performance aluminium exterior door with 92 mm system depth and quadruple glazing, achieving thermal coefficient of 0.85 W/m²K. Premium 34 mm articulated thermal break ensures lasting energy efficiency and structural stability.

The L335-1 aluminium exterior door is a premium solution for primary entrances, engineered for buildings requiring high energy efficiency and structural durability. With a 92 mm system profile and robust thermal insulation framework, it meets the highest European performance standards and delivers consistent thermal resistance across seasons.

Construction employs 3 mm aluminium profile reinforced with an articulated 34 mm thermal break that prevents heat transfer between exterior and interior environments. Three-stage EPDM gasket sealing maximizes resistance to air and water infiltration, protecting interior spaces in adverse weather conditions. The 92 mm leaf depth combined with 80 mm frame depth provides exceptional rigidity and long-term structural stability against wind loads and operational stress.

Thermal performance is certified by ift Rosenheim at Ud 0.85 W/m²K, positioning this door in the elite segment of energy-efficient entrance solutions. Quadruple glazing—comprising 44.1 triplex / 5 mm Satinato / 44.1 triplex—creates superior insulation barriers, dramatically reducing thermal losses while delivering acoustic comfort. Triplex treatment on each external layer ensures impact safety and compliance with security regulations.

Standard dimensions accommodate openings up to 1100×2300 mm, with single-leaf capability extending to 1200×2500 mm, providing design flexibility for diverse architectural layouts. The system supports swing configurations with extensive customization potential to match façade colour schemes and material palettes. Aluminium surface finishes can be adapted to project-specific aesthetic requirements without compromising performance.

Ideally suited for contemporary residential buildings, commercial properties, and projects with mandatory energy certification. The combination of aluminium resilience and thermal excellence makes it optimal for temperate climates and regions experiencing pronounced seasonal variations. Integrates seamlessly with aluminium window systems and modern architectural visions prioritizing efficiency alongside spatial clarity.

With a Ud coefficient of 0.85 W/m²K (certified by ift Rosenheim), this door ranks among the most thermally efficient aluminium systems available. The articulated thermal break of 34 mm, combined with quadruple glazing and triple-point EPDM sealing, delivers exceptional insulation and minimizes heat loss.

The door features a 3 mm aluminium profile with a total system depth of 92 mm and leaf thickness of 92 mm. The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) provides both thermal and acoustic insulation. Standard maximum dimensions: 1100×2300 mm; for single leaves, custom orders can reach up to 1200×2500 mm.

With a frame depth of 80 mm and total system depth of 92 mm, this door fits standard masonry (brick, concrete, lightweight blocks) and frames 80–120 mm wide. Installation requires proper opening preparation and level verification. For narrow frames (<80 mm) or irregular masonry, on-site measurement and frame extensions are recommended.

Maintenance is minimal: regular cleaning with water and neutral soap, especially in areas with direct sun exposure. The multi-point EPDM sealing should be inspected annually and replaced if degraded. The aluminium finish—anodized or painted—maintains its premium appearance over time with a slight patina developing in the first 3–5 years; UV exposure may cause slow colour fading. Professional treatments can extend the finish lifespan.

The system features robust 3 mm aluminium profiles and quadruple glazing that form a resistant structure. Details regarding RC classification (RC2/RC3), security hardware and concealed hinges depend on the specific configuration ordered. We recommend consulting with our showroom team to select the exact anti-intrusion protection level according to local standards and security requirements.

Yes, for single leaves, custom orders can reach up to 1200×2500 mm. For other proportions, double configurations, or special requirements for depth and finish, our team can provide personalized calculations and quotes based on drawings and site measurements.
