Aluminium exterior door L313 made to order

Aluminum exterior door with 92 mm system depth and exceptional thermal performance (Ud 0.85 W/m²K). Quadruple glazing and triple EPDM sealing for superior weather protection.

The L313 model represents a premium solution for exterior access points, combining aluminum structural strength with certified commercial-grade thermal performance. The 92 mm system depth and matching leaf thickness ensure seamless integration into modern façades with balanced, professional visual presence.

Construction merges a 3 mm aluminum frame with an articulated 34 mm thermal break, an architecture that substantially reduces heat loss. The quadruple-layered glazing—44.1 triple-laminate with satin-finish 5 mm interlayer—delivers both acoustic protection and solar control, while triple EPDM gaskets ensure superior airtightness throughout the door's lifespan. The Ud coefficient of 0.85 W/m²K, certified by ift Rosenheim, positions this door in the high energy-efficiency category according to current European standards.

Exceptional thermal performance combines with robust structural resistance to wind loads and extreme weather. Treated aluminum and integral drainage systems protect the door under adverse climatic conditions over decades. Quadruple glazing not only provides thermal isolation but also reduces exterior noise, making it ideal for exposed locations near traffic or severe weather zones.

Sizing flexibility—up to 1100×2300 mm for standard configurations and 1200×2500 mm for single leaves—enables adaptation to any architectural project. The system integrates easily with automation and access-control equipment, and accepts installation in diverse wall-cavity types.

L313 is recommended for luxury residences, commercial buildings with high energy-efficiency requirements, or renovation projects where insulation and contemporary aesthetics are priorities. Compatibility with pivot or sliding opening systems and a broad range of aluminum finishes make it a versatile choice for architects and builders.

The Ud coefficient of 0.85 W/m²K certified by ift Rosenheim places this door in the premium thermal insulation segment. This performance means reduced heat loss even in winter, increased comfort near the threshold, and lower heating bills. The articulated 34 mm thermal break in the aluminium profile combined with the specialized quadruple glazing deliver this efficiency.

The 3 mm thick aluminium profile is integrated with an articulated thermal break and provides structural strength with minimal weight. Aluminium does not warp under temperature changes, swell or contract, and is immune to corrosion—ideal for high-humidity areas or near water. The quadruple glazing and triple EPDM gaskets complete the overall weatherproofing.

The system features 3 EPDM gaskets arranged multi-point around the entire perimeter, creating an elastic and effective barrier against water infiltration and wind penetration. EPDM is a synthetic material that does not degrade under UV, remains flexible over time, and requires no frequent replacement. The 92 mm profile depth and quadruple glazing reinforce this protection, creating an impermeable and acoustic seal for the exterior entrance.

The standard offering is 1100×2300 mm, and for larger openings or atypical geometries, a single leaf can be ordered up to 1200×2500 mm. Each door can be customized to the centimetre based on your existing frame and masonry—final dimensions are determined during the site survey and design phase. We recommend contacting our team with photos of your current frame to ensure perfect fit.

Installation requires a stable frame (wood, aluminium, or PVC) and an opening with precise vertically and horizontally—deviations greater than 5 mm require structural adjustments. The 92 mm system depth must couple symmetrically with the wall for optimal sealing. We recommend installation on a specific threshold and structural polyurethane sealing. If the existing frame does not match or masonry is compromised, the installer will evaluate any necessary reinforcement.

Aluminium requires no special treatments, only periodic cleaning with water and neutral soap to remove dirt and deposits. EPDM gaskets should be inspected annually and lightly lubricated if stiffness is observed—do not use silicone which degrades the material. The quadruple glazing is cleaned like ordinary glass with gentle detergent. The 92 mm system and thermal insulation require no internal maintenance; the structure remains stable and functional for decades without intervention.
