Aluminium exterior door L392 made to order

Aluminium exterior door with 92 mm system depth and exceptional thermal performance (Ud 0.85 W/m²K), secured by quadruple glazing with triplex and satin glass. Contemporary solution for demanding entrance applications.

The L392 exterior door positions itself among premium aluminium solutions for main entrances, delivering the perfect balance between structural integrity and energy efficiency. Its 92 mm system depth and articulated thermal break of 34 mm ensure structural stability and high-performance insulation across cold climates and extreme weather conditions.

Construction combines aluminium's natural rigidity (3 mm profile thickness) with modern thermal isolation benefits. The system employs three-layer EPDM gaskets, guaranteeing superior air-tightness and long-term durability. The quadruple glazing—composed of 44.1 mm triplex, 5 mm satin glass, and 44.1 mm triplex again—is engineered to block thermal transition and reduce external noise transmission.

Certified thermal performance (Ud 0.85 W/m²K per ift Rosenheim) places this door in top insulation categories, reflecting European sustainable building standards. The combined resistance of the articulated profile and triple sealing system ensures optimal performance in passive buildings and energy renovation projects.

Dimensional flexibility ranges from 1100×2300 mm in standard configurations to 1200×2500 mm for single-leaf applications, adapting to a broad range of opening types and architectural styles. Aluminium offers customized finishing possibilities and coordinates seamlessly with complementary window systems.

The L392 exterior door is recommended for contemporary residences, commercial buildings, and heritage renovations requiring elevated insulation and climate control standards. It performs exceptionally within radiant floor heating systems and smart home integrations, supporting efficient heating-cooling cycles.

With a Ud coefficient of 0.85 W/m²K (ift Rosenheim certified), this door sits in the premium thermal insulation class, ideal for main entrances with high energy efficiency demands. The articulated 34 mm thermal break within the 92 mm aluminium profile ensures constant protection against heat loss and significantly reduces seasonal heating requirements.

The quadruple glazing system (44.1 triplex / 5mm Satinato / 44.1 triplex) combines security protection with exceptional acoustic and thermal performance. The laminated triplex layers absorb impact energy and prevent dangerous fragmentation, while the 5 mm gap provides superior sound insulation—essential for entrances in busy urban areas.

The structure combines 3 mm aluminium profile with a 92 mm door leaf and 80 mm frame, resulting in solid and rigid construction. Triple EPDM gasket sealing along the entire perimeter ensures complete protection against water and wind infiltration, while the elastomer flexibility maintains acoustic and thermal integrity over the long term.

Standard dimensions are fixed at 1100×2300 mm, but a single-leaf option allows custom sizing up to 1200×2500 mm, tailored to project-specific needs. For wider openings or non-standard proportions, the design team can develop custom solutions that maintain the system's thermal and structural integrity.

The 92 mm total depth profile integrates into standard frames or solid masonry with minimal opening preparation. The 80 mm frame provides sufficient depth for additional polyurethane insulation, and hidden hinge installation ensures a clean finish—whether flush-mounted or with discrete edges. Frame compatibility should be verified before ordering.

Aluminium requires no periodic repainting—occasional cleaning with mild soap and water maintains its shine. EPDM gaskets are inspected annually and can be easily replaced if worn. Triplex glass is cleaned like standard glazing, and silicone sealant around the frame should be checked every 5–10 years. Anodized or powder-coated finishes resist UV and don't degrade under normal exposure.
