Aluminium exterior door L124 made to order

Aluminium exterior door with 92 mm profile and advanced thermal performance certified Ud 0.85 W/m²K. Quadruple glazing and triple EPDM seals ensure lasting weather protection and energy efficiency.

The L124 exterior door is a premium aluminium solution designed for homes demanding high standards of comfort and energy efficiency. The robust 92 mm profile with an 80 mm frame depth ensures structural stability and a commanding visual presence. This model aligns with contemporary requirements for thermal protection and long-term durability.

The aluminium material features a 3 mm profile thickness combined with an articulated 34 mm thermal break system. This integrated insulation layer prevents heat conduction, maintaining stable interior temperatures year-round. Triple EPDM gaskets deliver superior sealing performance against water and wind, even in extreme weather. The aluminium finish is treated to resist corrosion and yellowing, preserving its original appearance over decades.

Energy performance is verified by ift Rosenheim certification with a thermal coefficient Ud of 0.85 W/m²K, positioning this door among high-performance solutions. The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex configuration) reduces heat loss and contributes to acoustic insulation, creating a quiet and comfortable interior environment. The 5 mm spaces between interior panes, filled with noble gas, amplify insulating effectiveness.

The door permits significant customization, with standard dimensions up to 1100×2300 mm and potential for larger configurations (up to 1200×2500 mm for single leaf). Opening systems are adaptable—pivot, classic swing, or easy-open configurations—according to space requirements and user preference.

This door is recommended for main entrances of villas, contemporary residences, and commercial spaces requiring refined presentation. Aluminium harmonises elegantly with marble, travertine, or solid wood flooring, creating transitions of maximum impact. Compatibility with underfloor heating systems and integration with modern automation makes it ideal for renovation and new construction projects.

The Ud value of 0.85 W/m²K (certified by ift Rosenheim) ranks this door in the top thermal insulation class, equivalent to Passive House standards. Quadruple glazing combined with an articulated 34 mm thermal break ensures maximum heat retention in winter and solar protection in summer, reducing both heating and cooling energy costs.

The 3 mm aluminium profile, combined with a total depth of 92 mm and 34 mm thermal break, creates a rigid yet lightweight and durable structure. The frame depth is 80 mm and the leaf 92 mm, ensuring secure seating on walls of varying thicknesses. Triple EPDM gaskets guarantee airtight sealing around the entire perimeter.

The standard maximum dimensions are 1100×2300 mm, but for a single leaf you can order up to 1200×2500 mm. Made-to-order customization allows perfect adaptation to your existing opening, whether you have modern frames or historic renovations with non-standard sizes. Our team calculates profiles and gaskets precisely for your wall.

Installation is done on the existing frame (masonry, concrete, or timber sill) with a minimum depth of 80 mm (frame depth) and ±20 mm tolerance in height. The 92 mm system accommodates walls with insulation, standard thicknesses of 200–400 mm. Fixing is achieved with screws and special anchors across the entire frame surface, and sealing is completed with EPDM gaskets and polyurethane mortar for complete joint closure.

The door features a solid 3 mm aluminium structure and 92 mm depth providing high resistance to impact and forced entry. While specific RC classification details are not provided, the triple EPDM system and compact structure form a strong foundation for premium hardware. We recommend RC2 or RC3 certification depending on your geographic location and local risks; our culttur.ro team will guide you in selecting the right locks and handles for your desired security level.

Aluminium requires no complex treatments — monthly cleaning with mild soap and water maintains its appearance. EPDM gaskets should be inspected annually and occasionally refreshed with neutral silicone to maintain elasticity. If the door has a painted finish, avoid aggressive solvents; if it has veneer or laminate, maintain constant humidity to prevent swelling. Hidden hinges and closing mechanisms require light lubrication once yearly — no frequent maintenance needed due to enclosed design.
