Aluminium exterior door L927 made to order

from2782.5 € + VAT

Aluminium exterior door with quadruple glazing and industry-leading thermal performance (Ud=0.85 W/m²K). Premium solution for contemporary spaces demanding energy efficiency and refined aesthetics.

The L927 aluminium exterior door is engineered for contemporary residences and commercial spaces where thermal performance and minimalist design converge. A 3 mm aluminium profile integrated within a 92 mm total system depth combines refined proportions with structural durability and aesthetic restraint.

The construction logic hinges on an articulated thermal break of 34 mm, ensuring effective separation between interior conditioned space and external climate. Quadruple glazing—two 44.1 mm triplex panes separated by 5 mm satin glass interlayer—optimises both acoustic and thermal insulation. Three-layer EPDM gaskets seal the frame perimeter, preventing water and air infiltration and guaranteeing long-term airtightness performance.

This door's performance is certified by ift Rosenheim, achieving a thermal coefficient of 0.85 W/m²K—a benchmark value in the aluminium door category. This translates to minimal thermal loss even in demanding European climates. The 92 mm system depth permits robust masonry fixing and accommodates various wall construction types, from traditional to high-performance envelope systems.

Standard maximum dimensions reach 1100×2300 mm; single-leaf configurations extend to 1200×2500 mm, providing dimensional flexibility for any architectural programme. Aluminium's inherent properties permit clean surface finishes and slender profiles, creating sharp lines and seamless transitions with the façade plane.

L927 integrates naturally into contemporary interiors, minimalist commercial environments, and homes prioritising energy efficiency and acoustic comfort. It complements solid wood flooring, polished concrete, and modern ceramic surfaces with visual restraint; the refined aluminium profile ensures its presence remains architecturally understated.

Frequently asked questions

The L927 achieves Ud = 0.85 W/m²K (ift Rosenheim certified) — a benchmark performance for profiled aluminium exterior doors. This is delivered by the articulated 34 mm thermal break and quadruple glazing with three layers of acoustic and thermal insulation. Result: minimal heat loss and sustained comfort.

The L927 profile has a total depth of 92 mm with an 80 mm frame and 92 mm leaf thickness. The profiled aluminium measures 3 mm and incorporates an articulated thermal break of 34 mm — the key insulation point. The quadruple glazing 44.1 Triplex / 5mm Satinato / 44.1 Triplex delivers top-tier acoustic and thermal protection. Sealing is via 3 EPDM gaskets at multiple points for a complete barrier against infiltration.

For standard configurations, the door reaches a maximum of 1100×2300 mm. For single-leaf solutions with special requirements, we can offer dimensions up to 1200×2500 mm. Each order is adapted to your specific masonry and frame — discuss directly with our team for custom variants and corresponding lead times.

Installation of the L927 door follows European standards with mechanical anchoring to wooden, metal or PVC frames depending on existing masonry. The 80 mm frame depth allows integration into frames of various thicknesses. Construction sealing with 3 EPDM gaskets ensures complete impermeability regardless of weather conditions. We recommend consulting a certified installer for perfect alignment.

The L927 door integrates quality hardware into the system with multi-point sealing for maximum structural resistance. The reinforced aluminium profile with 3 mm thickness, combined with triple glazing, delivers increased impact resistance. For specific RC2/RC3 certifications (anti-intrusion), our team can configure additional variants with concealed hinges and adjustable hardware — consult directly for security details.

The profiled aluminium of the L927 requires periodic cleaning with water and neutral detergent to maintain the finish. EPDM gaskets should be inspected annually and gently cleaned to ensure optimal sealing. Hardware is lubricated once yearly with light lubricant for frictionless operation. Anodized coating or wood-look finishes require no special intervention if undamaged — for deep cleaning and renewal, contact our support service.
