Aluminium exterior door L261 made to order

High-performance aluminum exterior door with quadruple Satinato glazing and certified thermal insulation. Robust system with thermal coefficient Ud 0.85 W/m²K, designed for contemporary entrances demanding superior energy efficiency.

The L261 aluminum door positions itself as a premium entrance solution for residential and commercial spaces prioritizing thermal performance and structural durability. The robust profile, developed to Greek engineering standards, delivers reference-class construction in the high energy efficiency category, certified through ift Rosenheim testing protocols. The system integrates seamlessly into contemporary architecture, where aluminum becomes an expression of modernism and constructive rigor.

The structural profile measures 92 mm in total depth, with an 80 mm frame and 3 mm aluminum leaf, ensuring stability and visual elegance. The articulated 34 mm thermal break, strategically positioned within the profile cavity, throttles heat transfer and maintains interior comfort regardless of external climate conditions. The quadruple glazing—44.1 triplex / 5mm Satinato / 44.1 triplex—guarantees both thermal insulation and a diffusing transparency that protects privacy without sacrificing luminosity. Triple EPDM gaskets create comprehensive sealing, preventing infiltration and ensuring long-term performance stability.

The thermal coefficient Ud 0.85 W/m²K exceeds current European standards, significantly reducing heat loss and contributing to a lower ecological footprint. The multi-layer construction absorbs exterior noise, delivering excellent acoustic insulation for residences in urban environments. Aluminum's inherent resistance to corrosion and extreme weather conditions guarantees longevity with minimal maintenance—routine cleaning only. The system is certified to European safety and structural performance regulations.

Standard dimensions reach 1100×2300 mm, accommodating the majority of residential entrances, while the single-leaf option extends to 1200×2500 mm for generous spatial solutions. The profile accepts custom glazing and RAL color options, enabling harmonious integration into any architectural context. Opening systems—hinged, sliding, or pivot—can be selected according to preference and available space.

This is the choice for modern main entrances, commercial spaces with energy efficiency demands, or premium renovations where construction quality and thermal performance are non-negotiable. Compatibility with heavy-load systems and personalization capacity make L261 a versatile platform for architects and designers seeking technical foresight combined with contemporary aesthetics.

The L261 achieves Ud = 0.85 W/m²K, certified by ift Rosenheim institute, placing it in the high-performance category for residential and commercial main entrances. This value meets requirements for low-energy buildings and significantly reduces seasonal heat loss. The aluminium profile combines a 34 mm articulated thermal break with quadruple glazing, ensuring structural stability and thermal efficiency.

The L261 system has a total depth of 92 mm, with a frame (jamb) of 80 mm and a leaf (door panel) of 92 mm thick. This depth aligns with standard European construction blocks and allows secure installation in existing openings with minimal adjustment gaps. Installation is performed by anchoring the frame into the masonry and applying multi-point sealing with EPDM gaskets around the entire perimeter, ensuring stability and waterproofing.

The quadruple glazing in 44.1 triplex / 5mm Satinato / 44.1 triplex configuration provides three levels of protection: superior thermal insulation through air spaces (which reduces heat transfer), significant acoustic performance boost, and impact resistance—triplex glass fragments into small harmless pieces. The Satinato finish also provides an elegant opaque surface that controls natural light and ensures privacy, ideal for entrances in urban areas.

The L261 system features 3 EPDM gaskets strategically placed on the frame and leaf, creating a continuous barrier against water, wind, and air infiltration during opening and closing. EPDM (synthetic elastomer) resists UV exposure and temperature fluctuations, maintaining elasticity for years. Multi-point sealing distributes pressure uniformly, reducing deformation over time and ensuring the door remains hermetically sealed throughout its lifespan.

The L261 model offers standard maximum dimensions of 1100×2300 mm, and for larger openings, can be configured with a single leaf up to 1200×2500 mm. Any dimension within these ranges can be customized to fit the exact opening on special order. For openings exceeding these limits or multi-leaf configurations, the showroom team can propose modular solutions or complementary systems.

Maintenance includes regular cleaning with water and neutral detergent and annual inspection of EPDM gaskets to ensure they remain elastic and crack-free. The aluminium profile (3 mm thickness) is treated for corrosion protection and requires no repainting, but available finishes include anodizing (silver, bronze), custom color coating, or wood-grain laminates for architectural integration. Glazing is cleaned only with a soft cloth and deionized water solution to avoid streaking.
