Aluminium exterior door L230 made to order

Aluminium entry door with articulated thermal break and exceptional insulation (Ud=0.85 W/m²K). Quadruple glazing and triple EPDM seals for superior weather protection.

The L230 positions itself as a premium exterior aluminium door solution, combining exceptional thermal performance with refined architectural presence. Its symmetrical profile and balanced proportions suit contemporary residences and selective renovations equally well. The system's 92 mm total depth ensures discreet integration into modern masonry without sacrificing structural integrity or functional reliability.

Construction employs 3 mm aluminium profiles paired with an articulated thermal break of 34 mm—a specification uncommon in standard-range doors. The quadruple glazing (44.1 triplex / 5 mm Satinato / 44.1 triplex) delivers superior thermal insulation alongside acoustic attenuation, critical in urban settings. Three EPDM gaskets create a three-stage seal that resists water and air infiltration across all pressure conditions. The 80 mm frame profile resists warping under mechanical stress and thermal cycling, maintaining alignment and gasket compression indefinitely.

A Ud coefficient of 0.85 W/m²K (ift Rosenheim-certified) confirms A-class thermal performance, significantly reducing heating loss and operational costs. This standard suits climates with severe winters and passive building protocols demanding rigorous envelope integrity. Independent testing validates pressure resistance and long-term durability, with opening options extending to 1200×2500 mm on single leaves—generous sizing for projects requiring substantial passages of light and air.

Colour and finish specifications adapt to RAL codes or metallic aluminium lacquers, aligning seamlessly with contemporary façade concepts. Operating systems—single, double, or dual-axis hinges—integrate within the wall plane, eliminating visible casings and heavy mechanical traces. Concealed gasketing and flush mechanisms complete the refined aesthetic.

L230 suits principal entries to villas, administrative buildings, and commercial spaces where thermal rigour and acoustic comfort matter equally. Its compatibility with radiant floor heating and alignment with future-building efficiency standards positions it within the passive and near-zero-energy construction framework.

This L230 model achieves a Ud coefficient of 0.85 W/m²K, certified by ift Rosenheim, thanks to its quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex) and articulated thermal break of 34 mm in the aluminium profile. Such performance ensures minimal heat loss and superior comfort at the threshold during winter months.

The L230 features 3 multi-point EPDM gaskets positioned on both frame and leaf, creating overlapping seals and additional acoustic insulation. These gaskets prevent water infiltration, dust ingress, and air leakage, ensuring optimal protection even under extreme weather conditions or in high-noise urban environments.

Standard dimensions reach up to 1100×2300 mm, and for a single leaf configuration up to 1200×2500 mm. As a premium showroom product, this door can be fully customized to your exact dimensions within structural and certification limits, with production timelines adapted to your project requirements.

The L230 has a total thickness of 92 mm (leaf 92 mm, frame 80 mm), with 3 mm aluminium profile walls. This robust depth accommodates the 34 mm articulated thermal break and quadruple glazing, creating superior thermal mass that retains heat and reduces external noise penetration.

Underfloor heating compatibility is not specified for the L230 model in the available technical data. We recommend consulting with our showroom team, who will evaluate your specific installation requirements and provide tailored threshold solutions for radiant heating systems.

Specific finish details (spray paint, anodizing, or veneer) are not listed in the technical specifications. Contact our showroom team to request available colour and texture collections. Aluminium requires regular cleaning with water and mild soap; this premium door's finish ensures excellent resistance to oxidation and urban pollution.
