Aluminium exterior door L910 made to order

Aluminium exterior door L910, ift Rosenheim certified with thermal coefficient Ud=0.85 W/m²K. 92mm system featuring quadruple glazing and triple EPDM sealing for superior thermal and acoustic performance.

The L910 exterior door represents a premium aluminium access solution engineered to meet the most demanding European standards for thermal and acoustic insulation. Manufactured to Greek quality specifications, it is positioned within the category of high-performance systems dedicated to residential and commercial buildings requiring long-term durability and energy efficiency.

The 3 mm aluminium profile with a total system depth of 92 mm incorporates an articulated thermal break of 34 mm, effectively minimising thermal bridges. The quadruple glazing—featuring two 44.1 mm triplex panes separated by a 5 mm satin glass interlayer—delivers superior insulation, complemented by three EPDM gaskets that guarantee lasting weather-tightness throughout the product's lifespan. The frame depth of 80 mm and leaf thickness of 92 mm ensure exceptional structural rigidity and dimensional stability across varying climatic conditions.

The ift Rosenheim certified thermal performance, with a Ud value of 0.85 W/m²K, classifies this door among high energy efficiency categories, substantially reducing heat loss and contributing meaningfully to the building's overall energy balance. Acoustic insulation benefits directly from the glass mass and sealed opening system, making it particularly suited for urban locations with elevated noise exposure. The ift certification confirms compliance with durability, weather-tightness and climate resistance standards.

The system accommodates standard dimensions up to 1100×2300 mm, with single-leaf options extending to 1200×2500 mm, offering architectural design flexibility. Dimensional variability and customisation options ensure adaptability to any opening type, from main residential entrances to utility access points. Available finishes and opening systems—pivot, swing or double-action—align with the specific functional requirements of each project.

Recommended applications include main entrances of contemporary residences, access points in commercial and hospitality spaces, and exit doors in high-standard residential buildings. Compatibility with radiant floor heating systems and intelligent climate control makes it ideal for building renovations targeting energy certification standards. Partnership with premium sliding or pivot systems completes an elegant and durable access solution.

The Ud coefficient of 0.85 W/m²K (ift Rosenheim certified) places this door in the premium insulation category, exceeding mandatory standards for exterior doors. Performance is achieved through the 92 mm system depth, articulated thermal break of 34 mm, and quadruple glazing with three 5 mm layers that retain heat efficiently and reduce heating energy consumption.

For an exterior door, quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) is not just over-protection — it is an investment in durability and comfort. The asymmetrical configuration with 5 mm layers and Satinato glass optimizes thermal insulation, reduces condensation and external noise, while triplex layers add safety against mechanical impacts. For temperate European climate and long-term use, this combination justifies energy efficiency and structural resistance.

The articulated thermal break of 34 mm in the L910 profile combines structural flexibility with continuous insulation — articulated polyamide allows thermal and mechanical micro-movements without compromising pressure balance. Unlike rigid breaks, the articulated version prevents micro-cracks from aluminium expansion and contraction through seasonal cycles, maintaining multi-point sealing integrity. This ensures durability over 20-30 years with constant thermal performance regardless of climate variations.

Standard maximum dimensions are 1100×2300 mm, and for a single leaf (pivot or standard opening) you can reach up to 1200×2500 mm. Any customization needs are discussed directly with the showroom team — for example, symmetric double doors, adapters for existing masonry, or projects with geometric irregularities can be accommodated with custom technical solutions. We recommend preliminary consultation to validate feasibility and delivery times.

The three-point EPDM seals are durable and only require regular cleaning with water and neutral detergent — no lubrication needed and they resist UV and temperature variations well for 15-20 years. Degradation occurs only if constantly exposed to extreme humidity or industrial ozone; under normal European conditions, maintenance is limited to seasonal cleaning and annual visual inspection. If the seal dries or deforms, replacement is straightforward without opening the profile.

The system depth of 92 mm and frame depth of 80 mm are compatible with standard modern masonry (brick, concrete) and existing aluminium or wooden frames. Installation is done with anchoring angles and elastic sealing (polyurethane) to ensure thermal and mechanical mobility. For non-standard existing frame widths or for adaptation to renovation projects, on-site evaluation with a specialist from the team is recommended; this validates existing thickness, utility penetrations, and need for additional projections.
