Aluminium exterior door L430 made to order

Aluminium exterior door L430 with 92 mm profile depth and quadruple glazing, thermal performance Ud 0.85 W/m²K certified by ift Rosenheim.

L430 is a premium-grade aluminium exterior door designed for contemporary residential and commercial buildings requiring both maximum performance and architectural elegance. The compact 92 mm profile (80 mm frame, 92 mm leaf) with 3 mm aluminium thickness delivers a rigid, refined structure typical of high-end Greek engineering solutions.

Construction features an articulated thermal break of 34 mm that effectively minimizes heat transfer, paired with triple EPDM gaskets providing complete weather sealing. The quadruple glazing (44.1 triplex / 5 mm Satinato / 44.1 triplex) ensures exceptional light control and privacy, with satin-finish surfaces delivering a sophisticated, contemporary aesthetic.

Thermal performance of Ud 0.85 W/m²K (ift Rosenheim certified) places this door in the top tier of exterior solutions, guaranteeing long-term energy efficiency and reduced heating costs. The 92 mm total depth accommodates seamless installation in diverse wall constructions and modern building systems. Triple-layer EPDM sealing ensures durability against weathering and provides significant acoustic insulation.

L430 accommodates standard dimensions up to 1100×2300 mm on a single leaf, extending to 1200×2500 mm for generous, open architectural statements. Opening systems—hinged, pivot, or sliding—adapt to spatial requirements from single-family residences to premium commercial facades.

Ideal for primary entrances on modern residences, high-end renovations, and commercial projects with elevated standards. Pairs naturally with matching window systems and minimalist or industrial-contemporary interiors. Greek manufacturing and European certifications ensure reliability across extended lifecycles.

The L430 achieves a thermal coefficient Ud of 0.85 W/m²K, certified by ift Rosenheim, representing excellent performance for temperate continental climate. This is achieved through quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex) and an articulated thermal break of 34 mm in the aluminium frame. For harsh winters in regions like Transylvania or Moldova, this is an efficient solution that significantly reduces heat loss.

The L430's total depth of 92 mm is structured as: the frame at 80 mm (which sits within standard 20-30 cm wall depth) and a 92 mm leaf thickness. This fits perfectly within standard Romanian masonry. Any visual protrusion is minimal, and finishing can easily adapt to thicker walls using extension profiles and trim systems.

The L430 uses 3 EPDM gaskets strategically positioned (perimeter and along the leaf thickness) creating a multi-point sealing system. This prevents water and wind infiltration during extreme rain or snow conditions. EPDM is UV-resistant and handles thermal cycles, lasting years without degradation. For a main entrance door where sealing directly impacts indoor comfort and energy consumption, this is critical.

The L430 is a classic exterior door with standard frame and hidden hinges, not a pivot system. The opening mechanism is conventional and integrates perfectly with standard masonry construction. If your project requires pivot hardware (wider openings, distinctive architectural proportions), this is not the recommended option — we can discuss our pivot door collections.

Yes, the L430 can be manufactured to order. The recommended standard size is 1100×2300 mm, but the system allows up to 1200×2500 mm for a single leaf. For wider openings, we offer dual-leaf configurations with a central mullion. Any custom dimension requires technical approval and 4-6 week production lead time.

The L430 can be finished in custom paint (RAL colours) or premium veneer. The 3 mm aluminium thickness and thermal break protect structural cores from expansion. For painted finishes, we recommend annual cleaning with neutral soap and water. Veneer surfaces benefit from light protective wax every 2-3 years and should avoid direct sun exposure (blinds recommended). Both finishes last 15-20 years with proper care.
