Aluminium exterior door L240 made to order

Exterior aluminium door with premium profile and quadruple glazing, delivering exceptional thermal insulation and long-term durability in demanding climates.

The L240 is a contemporary exterior access solution engineered from structural aluminium with a profile optimised for superior thermal performance. Designed for premium commercial and residential spaces, this collection merges engineering rigour with clean European lines, defining modern design intent. The 92 mm overall system depth and 80 mm frame ensure remarkable structural integrity, supporting large-format doors without compromise.

Materials are selected for longevity: 3 mm laminated aluminium, equipped with an articulated 34 mm thermal break, significantly reduces heat transfer between exterior and interior environments. Triple EPDM gaskets deliver complete weatherproofing, while the quadruple glazing system—triplex 44.1 / 5 mm Satinato glass / triplex 44.1—achieves the optimal balance between light transmission and thermal protection. Aluminium finishing enables aesthetic personalisation and effortless maintenance throughout the lifespan.

Certified thermal performance (Ud = 0.85 W/m²K to ift Rosenheim) places this door among the most efficient exterior solutions, reducing energy loss and guaranteeing consistent climate control. The 92 mm leaf thickness and multi-layer glazing system contribute equally to acoustic insulation, transforming the entrance into an effective urban noise barrier. International certifications validate compliance with European safety and energy efficiency standards.

Dimensional flexibility—available in standard format up to 1100×2300 mm and single-leaf variant to 1200×2500 mm—accommodates any architectural configuration, from residential entries to major commercial access points. Opening systems can be tailored (hinged, pivot, sliding), and finishing selected from standard palette or custom RAL colours.

In luxury spaces—private residences, hotels, corporate headquarters, or high-end showrooms—the L240 integrates seamlessly alongside natural stone flooring, designer parquet, or patinated concrete. Subtle reflections in Satinato glazing create a refined transition between exterior and interior, maintaining visual coherence with contemporary architecture.

With a thermal coefficient Ud of 0.85 W/m²K (certified by ift Rosenheim), this door achieves premium-class thermal insulation, surpassing the majority of standard exterior doors. The exceptional performance is due to the combination of profile thickness (92 mm), articulated thermal break of 34 mm, and quadruple glazing with advanced insulation layers. This translates to significant heat loss reduction and lower energy bills year-round.

This door's profile has a total thickness of 92 mm — 80 mm at the fixed frame and 92 mm at the leaf — with 3 mm aluminium reinforcement. This substantial thickness ensures exceptional structural rigidity and long-term durability, even in extreme climatic conditions (thermal shock, high winds, pollution). The 3 mm aluminium prevents deformation and distortion that can occur over time in thinner doors.

The door is equipped with quadruple glazing 44.1 triplex / 5 mm Satinato / 44.1 triplex, a premium exterior configuration. Multiple layers of laminated glass (44.1 triplex) alternate with air spaces and satin glass, creating superior thermal and acoustic insulation. This significantly reduces external noise (traffic, wind) and maintains indoor heat, while laminated triplex glass offers impact resistance and forced-entry protection in case of breakage.

The door uses a multi-point sealing system with 3 strategically positioned EPDM gaskets on fixed frames and movable leaves. These gaskets compress uniformly when the door closes, creating a continuous and impermeable barrier that resists rainwater, wind, and air infiltration. The EPDM system is UV and ozone-resistant, performing optimally even in Mediterranean or oceanic climates, without degradation over time.

Standard dimensions are 1100×2300 mm for double configurations and up to 1200×2500 mm for single leaves. However, as a premium aluminium product, this door can be custom-ordered according to your project needs and masonry specifics. We recommend consulting a showroom specialist to assess the space and determine optimal sizing, including frame positioning and compatibility with existing systems.

Installation requires a professional assessment of the masonry (flatness, moisture, integrity) and frame adaptation to opening dimensions. The 92 mm profile integrates easily into standard frames, but it is essential that the masonry is free from deformations or infiltrations. After frame mounting, perimeter sealing is done with polyurethane foams and specific sealants to ensure thermal and acoustic performance. We recommend installation by certified specialists to ensure compliance and long-term durability.
