Aluminium exterior door L123 made to order

from2310 € + VAT

Aluminium exterior door with 92 mm system depth and exceptional thermal performance. Quadruple glazing and 34 mm thermal break provide superior insulation and year-round comfort.

The L123 exterior door represents a modern, performance-driven solution for primary or secondary access points, engineered within a series of high-grade aluminium closure elements. Its solid profile and robust construction recommend it for varied climatic exposures, delivering a refined architectural presence and reliable serviceability.

Construction combines extruded aluminium profiles at 3 mm thickness with a carefully engineered internal structure. The 92 mm system depth integrates an articulated 34 mm thermal break, which efficiently separates exterior and interior thermal flows. Triple EPDM gaskets ensure sealing across three contact lines, while the quadruple glazing (44.1 triplex / 5 mm satinato / 44.1 triplex) combines insulating performance with sound protection and visual privacy.

The Ud coefficient of 0.85 W/m²K (certified by ift Rosenheim) positions this solution among high-efficiency thermal products, suited for buildings pursuing low-energy consumption standards. The system is tested and validated for moderate to high climatic exposures, guaranteeing dimensional stability and structural integrity over time.

Available dimensional ranges—up to 1100×2300 mm in standard configuration, or 1200×2500 mm for single leaves—allow adaptation to varied façades and wider passage spaces. The 80 mm frame depth and 92 mm leaf thickness support secure installation in both traditional and insulated walls. Surface finishes and opening systems can be tailored to architectural or functional requirements.

Recommended for primary entrances in contemporary homes, mixed-use buildings, or commercial spaces requiring robust thermal and acoustic insulation, combined with operational ease and clean aesthetics.

Frequently asked questions

The door achieves a Ud value of 0.85 W/m²K, certified by ift Rosenheim, combined with a 34 mm articulated thermal break and quadruple glazing. This composition delivers exceptional climate control and substantially reduces heating losses.

The structure features 3 mm aluminium profile within a 92 mm system depth, paired with 44.1 mm triple laminated glass on both sides and 5 mm satin glass at the center. Aluminium provides outstanding corrosion resistance and weathering durability, while lamination ensures long-term stability.

The door is equipped with 3 multi-point EPDM gaskets around the entire frame perimeter, creating a continuous barrier against water and wind. The articulated sealing system works synergistically with the 80 mm frame depth and drainage slope, preventing infiltration even under heavy rain.

The model offers standard dimensions of 1100 × 2300 mm, and for special requirements you can request a single leaf up to 1200 × 2500 mm. Our showroom consultants can analyse your space and recommend the optimal configuration, whether standard or fully customised.

The 80 mm frame depth ensures compatibility with most standard walls — brick, concrete, and external insulation systems. Installation requires qualified personnel to respect drainage slope and sealing channels. Our showroom consultations include site assessment and compatibility verification before ordering.

Aluminium requires no repainting and cleans easily with water and mild soap. EPDM gaskets should be inspected annually for wear, and laminated glass resists UV and oxidation without fading. Standard anodised or patinated finishes provide decades of protection — the door grows more durable over time, not more fragile.
