Aluminium exterior door L554-3 made to order

Aluminium entrance door with 92 mm profile and quadruple glazing, engineered for premium thermal performance (Ud 0.85 W/m²K). The articulated 34 mm thermal break and triple EPDM sealing deliver exceptional durability and climate control.

The L554-3 aluminium entrance door represents a benchmark entry solution, merging thermal efficiency with refined minimalist architecture. The 3 mm aluminium construction, paired with a robust 92 mm profile, delivers a solid, contemporary presence on any premium residence façade. The system is engineered for installation flexibility and adaptation across diverse architectural contexts.

The technical foundation rests on an articulated thermal-break system of 34 mm that prevents unwanted heat transmission and maintains dimensional stability over decades. The quadruple glazing — configured as 44.1 triplex / 5mm Satinato / 44.1 triplex — provides even optical load and visual clarity, while three EPDM gaskets ensure complete sealing against the elements. The system's total depth of 92 mm and frame depth of 80 mm integrate discreetly into ventilated or solid wall structures.

Thermal performance (Ud 0.85 W/m²K, ift Rosenheim certified) positions this door in the highest thermal-block category, significantly reducing energy loss and supporting interior comfort during extreme weather. Triple EPDM sealing and the profile's deep articulation deliver resistance to barometric fluctuations, high winds, and humidity variations without compromising smooth operation.

Standard sizing up to 1100×2300 mm and single-leaf options to 1200×2500 mm permit granular adaptation to project proportions. Aluminium offers complete freedom in finishing — from pure RAL colours to patina or metallic treatments — and integrates seamlessly with contemporary glazing systems and discrete hardware.

The L554-3 suits contemporary residences, retrofits to passive or near-passive standards, and spaces demanding an entrance door with distinct architectural identity and demonstrated climate performance. Compatibility with mechanical and automated closure systems makes it suitable for both daily access and advanced security installations.

The Ud coefficient of 0.85 W/m²K (ift Rosenheim certified) places this door in the premium thermal insulation category. The articulated thermal break system of 34 mm, combined with quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex), ensures superior heat retention and significant reduction in energy losses. This value exceeds current European standards for high-performance external doors.

The door is constructed from aluminium profile 3 mm thick, with a total system depth of 92 mm and leaf thickness of 92 mm. The frame has a depth of 80 mm. The core of the system includes an articulated thermal break of 34 mm that guarantees thermal separation between interior and exterior. The glazing is quadruple (44.1 triplex / 5mm Satinato / 44.1 triplex), delivering both robust thermal and acoustic insulation.

The sealing system comprises 3 EPDM gaskets strategically positioned to block water and air infiltration at critical junction points of the door. EPDM gaskets offer durability over time and resistance to thermal variations and UV exposure, maintaining elasticity long-term. The combination of these three sealing layers with the articulated thermal break profile ensures a multi-point barrier, which is essential for thermal performance and indoor comfort in extreme weather conditions.

Standard dimensions available are up to 1100×2300 mm for classic configurations, with the possibility of reaching 1200×2500 mm for single leaf setups. Beyond these sizes, the door can be customized to order based on your project specifications. For cases exceeding standard dimensions, we recommend direct consultation with the design team to validate system compatibility and ensure proper installation within existing frame and masonry.

Installation requires careful preparation of the frame opening and masonry hole, with verification of flatness and level. The frame depth of 80 mm allows solid integration into modern masonry (brick, concrete, etc.), while the total profile of 92 mm provides sufficient space for insulation and fastening. We recommend installation with anchor screws at prepared joints, with perimeter sealing using polyurethane or silicone to complement the internal EPDM sealing. For projects with high-performance requirements, consultation with a qualified installer is essential.

The aluminium profile requires periodic cleaning with water and neutral detergent to maintain appearance and prevent corrosion buildup. EPDM gaskets should be inspected annually and cleaned of dirt and debris; in cases of severe wear, they can be replaced without affecting system integrity. The opening mechanism should be lubricated periodically (aluminium-safe oil) to ensure smooth operation and durability. For installations exposed to extreme conditions (salinity, high humidity), we recommend additional protective treatments of perimeter seals every 5-7 years.
