Aluminium exterior door L933 made to order

Aluminium exterior door with 92 mm profile and exceptional thermal performance (Ud = 0.85 W/m²K). Premium entry solution featuring quadruple glazing and triple EPDM sealing for contemporary homes.

The L933 model is a benchmark exterior door solution for contemporary residential entrances. Built from 3 mm aluminium with a 92 mm system profile depth, it delivers exceptional structural rigidity and understated minimalist aesthetics. This collection positions itself in the premium segment, designed for discerning homeowners who prioritize technical performance alongside refined design.

The system integrates a sophisticated 34 mm articulated thermal break that effectively interrupts heat conduction between exterior and interior surfaces. The glazing is a carefully engineered quadruple composition: 44.1 mm triplex outer pane, 5 mm Satinato glass with satin finish, and 44.1 mm triplex inner pane. Three-level EPDM gaskets ensure maximum air-tightness and superior acoustic insulation. The entire assembly carries ift Rosenheim certification, a guarantee of European compliance and long-term durability.

Thermal performance is remarkable: the Ud value of 0.85 W/m²K places this door among the market's most efficient solutions. This translates to minimal heat loss during winter months and significant reductions in energy bills. The mechanical strength of the aluminium profile, combined with the 92 mm leaf thickness, delivers robust protection and exceptional durability, even under challenging climatic conditions.

Sizing options are flexible: standard maximum format is 1100×2300 mm, while single-leaf configurations can reach 1200×2500 mm. The 80 mm frame depth enables seamless integration into existing construction with minimal adaptation. The operating system and mounting details are engineered for reliability, built to withstand daily use without compromise.

L933 is ideal for modern homes, passive house projects, bioclimatic buildings, and any development where energy efficiency and interior comfort are paramount. It integrates seamlessly into minimalist and contemporary architectural contexts, complementing polished concrete floors, natural timber, or refined tile finishes. Investment in a door of this calibre quickly pays dividends through energy savings and long-term property value appreciation.

The thermal coefficient Ud is 0.85 W/m²K, certified by the German ift Rosenheim institute, placing this door among the best in class for ultra-low energy buildings. The 34 mm articulated thermal break combined with quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) eliminates thermal bridging and ensures consistent insulation performance.

The system has a total depth of 92 mm with a frame thickness of 80 mm and leaf thickness of 92 mm. This profile depth is ideal for modern construction with external insulation, easily adjusted in the door frame to accommodate standard 30 cm walls or thicker insulated masonry. The premium hardware ensures smooth and secure operation regardless of installation depth variations.

This door features 3-point EPDM gasket sealing across multiple layers, preventing water infiltration and air leakage throughout its lifespan. The 3 mm aluminium profile combined with the articulated thermal break creates a rigid, durable structure with completely closed sections and no weak access points. Professional installation documentation ensures proper security hardware integration and long-term weather protection.

Yes, this door is made-to-order and can be customized to your exact dimensions. Standard sizes range up to 1100×2300 mm, with single leaves accommodating up to 1200×2500 mm. For non-standard openings—narrower, taller, or dual configurations—custom manufacturing preserves the certified thermal performance and structural integrity. Our specialists assist with dimension planning to ensure perfect fit and optimal functionality.

The 3 mm aluminium is naturally corrosion-resistant and requires no periodic repainting—standard anodic finishes maintain appearance for decades. The three-layer EPDM seals remain efficient far longer than conventional systems, and annual hardware tightening (a simple 5-minute task) preserves sealing integrity. The Satinato quadruple glazing resists impacts and thermal stress exceptionally well, requiring only regular cleaning with neutral detergent to maintain clarity and performance.

The 34 mm articulated thermal break is a reinforced polyamide structure that separates inner from outer aluminium, preventing heat conduction. Unlike rigid breaks, the articulated design flexes slightly under thermal and mechanical stress, eliminating the risk of micro-cracks and maintaining sealing integrity over decades in extreme temperature conditions. This flexibility delivers the certified Ud value of 0.85 W/m²K with permanent structural reliability.
