Aluminium exterior door L101 made to order

Premium aluminum exterior door with ultra-slim profile and quadruple glazing. Thermal performance Ud 0.85 W/m²K and operable up to 1200×2500 mm.

The L101 model is a premium aluminum exterior door designed for contemporary architectural projects that prioritize clean lines and energy efficiency. The compact 92 mm total system depth and precisely engineered 3 mm aluminum profile deliver a refined, understated presence—ideal for minimalist or modern façades. Its positioning reflects current design expectations: generous proportions, substantial construction that communicates durability and integrity.

Construction combines anodized aluminum with an articulated thermal break of 34 mm, the critical element maintaining thermal separation between interior and exterior zones. Frame profile (80 mm) and leaf (92 mm) are calibrated to house a specialized quadruple glazing system: 44.1 triplex exterior, 5 mm Satinato glass center, and 44.1 triplex interior—a configuration that maximizes insulation while preserving transparency. Triple EPDM gaskets ensure water and wind tightness across all weather conditions.

Thermal performance of Ud 0.85 W/m²K (ift Rosenheim certified) positions this door in the Elite category for exterior solutions in temperate and cold climates. The quadruple glazing delivers additional acoustic protection in urban contexts or near noise sources. Mechanical robustness of the profile and multi-layer sealing system ensure reliable performance over decades with minimal maintenance.

Available formats address residential and commercial requirements: 1100×2300 mm standard, with single-leaf openings up to 1200×2500 mm. The operating system—swing, pivot, sliding—is selected according to architectural intent and available space. Aluminum allows personalized finishes: natural anodize, RAL lacquers, or patinas that reference other materials.

L101 integrates seamlessly into modern holiday residences, office buildings with glazed façades, and urban renovations where energy efficiency and minimalist aesthetics are paramount. Paired with polished concrete flooring, large-format stoneware, or premium laminates, it reinforces the perception of sophisticated, contemporary space.

Ud 0.85 W/m²K is an excellent thermal insulation value, certified by ift Rosenheim laboratory, placing this door in the premium performance category. This low coefficient reduces heat loss by up to 40% compared to standard doors, resulting in lower heating bills and consistent comfort even on cold days.

The 34 mm articulated thermal break in 3 mm aluminium interrupts heat conduction through the frame, while the quadruple glazing (44.1 triplex / 5 mm Satinato / 44.1 triplex) creates insulating chambers that trap warm air. The combination of these two parameters—slim profile with internal thermal protection and four-layer glass—is responsible for the exceptionally low Ud performance and also reduces external noise by approximately 35-40 dB.

For standard openings, you can choose up to 1100×2300 mm, and for a single leaf, dimensions can reach 1200×2500 mm—perfect for generous spaces and modern architectural proportions. All dimensions are customizable to order: our team adapts the frame and quadruple glazing precisely to your opening measurements, depending on the door profile and wall specifications.

The L101 door is installed with a standard or wide frame system (compatible with brick, concrete, or stone masonry) and requires precise opening preparation according to profile specifications. The 80 mm frame is anchored into the wall with stainless steel anchors, and the three-point sealing (3 EPDM gaskets) ensures vibration-free and leak-free operation. Installation requires exact leveling and perimeter grouting, and our team provides detailed support with technical drawings for each masonry type.

The aluminium profile (3 mm thickness) is available in painted or anodized finishes with maximum durability, and the Satinato glass offers an elegant matte finish that easily hides fingerprints. Maintenance is minimal: monthly cleaning with slightly soapy water and a soft cloth for the glass, and annual light lubrication of the hinges ensures perfect operation for years to come. Aluminium requires no patching or additional painting—the factory-applied finish is weather and UV resistant.

Specific security details (RC class, hardware type, and multi-point locking mechanisms) will be confirmed depending on your custom order configuration. The quadruple glazing with triplex layers (44.1) offers impact resistance and significant slowdown of any force-based breaking attempts. We recommend a technical consultation to select exactly the protection level you need (RC2 or RC3), considering your property location and specific security requirements.
