Aluminium exterior door L992 made to order

Aluminium exterior door L992 with 92 mm profile depth and superior thermal performance (Ud=0.85 W/m²K), featuring quadruple glazing and triple EPDM sealing. A robust entry solution for primary doors in moderate to cold climates.

The L992 exterior door is a premium aluminium solution designed for primary entries in residential and commercial buildings requiring superior thermal and acoustic performance. The compact 92 mm system profile combines structural efficiency with contemporary aesthetics, establishing a solid position among high-performance exterior doors that demand reliability and durability.

This door's construction features a 3 mm aluminium profile reinforced by an articulated 34 mm thermal break that fragments the heat pathway and significantly reduces thermal transmission. The 92 mm panel is completed with specialized quadruple glazing—two 44.1 triplex panes separated by a 5 mm Satinato interlayer—offering both thermal protection and visual control. Triple EPDM gasket sealing creates a compact barrier against air and water infiltration, contributing to long-term performance and low maintenance requirements.

The certified thermal performance (Ud=0.85 W/m²K per ift Rosenheim testing) places this door in a high efficiency category, reducing heating demands during cold periods and minimizing thermal losses. The triple sealing system and generous glazing thickness also deliver respectable acoustic insulation—critical for entries in urban areas or traffic-exposed locations. The robust construction resists wind pressure, mechanical stress, and thermal expansion typical in extreme climates.

The L992 is available in standard sizes up to 1100×2300 mm (dual leaves) and single-leaf variants up to 1200×2500 mm, allowing design flexibility. Customization includes RAL-matched powder coating or anodized finishes, plus hardware and opening mechanisms tailored to functional and aesthetic requirements.

Recommended for primary entries in residences with high thermal comfort standards, premium commercial buildings, and spaces with demanding acoustic needs. It integrates seamlessly with stone, marble, or premium tile flooring, completing a sophisticated and future-proof design approach.

Ud 0.85 W/m²K is an excellent thermal insulation value, certified by ift Rosenheim, indicating minimal heat loss through the door. The 34 mm articulated thermal break in the aluminum profile interrupts heat transfer, while the quadruple glazing (44.1 triplex + 5mm Satinato + 44.1 triplex) provides five-layer insulation. This performance directly reduces heating costs, particularly in cold climates.

The quadruple glazing on L992 (44.1 triplex + 5mm Satinato + 44.1 triplex) features four glass panes with inner thermal and sound-dampening layers. Compared to double glazing with just two panes, this multi-layer composition reduces heat loss by approximately 60–70% more than standard solutions and significantly improves acoustic insulation.

Standard dimensions up to 1100×2300 mm are available off-the-shelf; for larger or non-standard openings, custom orders can accommodate single-leaf doors up to 1200×2500 mm. Our showroom specialists in București can adapt the frame profile to your wall dimensions and recommend two-leaf solutions if your opening exceeds these limits.

The system uses three EPDM gaskets (high-quality elastomer) positioned on the top, bottom, and sides of the frame, creating a continuous barrier against water and wind. EPDM remains flexible even in extreme temperatures (–40°C to +80°C), and maintenance requires only periodic cleaning with water and annual inspection for cracks. In temperate climates, the lifespan is 15–20 years without structural repairs.

The frame is 80 mm deep and made from aluminum with a 34 mm articulated thermal break, making it durable and easily adaptable to various wall thicknesses (concrete, brick, or mixed materials). The profile allows installation in masonry per DIN 18202, with maximum vertical and horizontal deviation of ±5 mm. After installation, it is sealed with polyurethane foam and acrylic paint for secure, weather-proof finishing.

The L992 is specifically designed for temperate and cold climates thanks to its Ud 0.85 W/m²K coefficient and quadruple glazing. EPDM seals maintain flexibility even at –40°C, preventing cracks and leaks. The 34 mm thermal break prevents condensation on the interior frame even on extremely cold days, and ift Rosenheim testing guarantees performance under extreme conditions. For regions with sustained temperatures below –30°C, we recommend consulting our specialist for additional insulation upgrades.
