Aluminium exterior door L152 made to order

Aluminium entrance door with slender profile and superior thermal insulation. Quadruple-glazed triplex glass for maximum weather protection and acoustic comfort year-round.

The L152 is a contemporary exterior entrance solution engineered with an efficient aluminium profile and 92 mm system depth. Its slender, clean lines integrate seamlessly into modern architecture, while thermal performance certified by ift Rosenheim (Ud = 0.85 W/m²K) provides reliable defence against heat loss and water infiltration. This positions it within the premium segment for buildings demanding high energy-efficiency standards.

Construction combines a 3 mm aluminium frame with a specialised core — an articulated 34 mm thermal break that significantly reduces cold transfer. Triple EPDM gaskets seal the frame perimeter uniformly, protecting interiors from wind, rain, and sound transmission. The complete leaf thickness of 92 mm ensures stability and durability under frequent mechanical stress, withstanding daily use in busy environments.

The quadruple-glazing system — 44.1 triplex satin / 5 mm / 44.1 triplex — exemplifies top-tier insulation standards. This configuration delivers exceptional thermal protection alongside elevated acoustic insulation, creating a calm and controlled interior environment. Independent ift Rosenheim certification validates reliability through rigorous testing, a benchmark for investment properties and quality residential projects.

Flexible dimensioning — up to 1100×2300 mm in standard configuration and up to 1200×2500 mm for single-leaf applications — accommodates specific spatial requirements. The 80 mm frame depth integrates smoothly into contemporary masonry without demanding extensive structural modifications, while aluminium finishes maintain visual cohesion with other metallic building elements.

Ideal for primary entrances in single-family homes, residential apartment blocks, and commercial buildings where energy efficiency and contemporary aesthetics are priorities. L152 pairs naturally with spaces of moderate solar exposure and continental climates, ensuring year-round thermal and acoustic comfort.

The Ud thermal coefficient is 0.85 W/m²K, placing it in the superior performance category for aluminium exterior doors. This is achieved through a 34 mm articulated thermal break and quadruple-glazed triplex glass (44.1 triplex / 5mm satin / 44.1 triplex), which minimizes heat loss and ensures consistent comfort in cold seasons.

Yes, this door is fully compatible with underfloor heating systems thanks to its modern aluminium profile and superior thermal insulation. The total system depth of 92 mm and the 34 mm articulated thermal break ensure uniform heat distribution without creating cold zones near the door.

The door is available in standard dimensions up to 1100×2300 mm for standard leaf configurations and up to 1200×2500 mm for single leaf. For any customization beyond these standard limits, our team can manufacture the door to exact specifications – please contact our consultant to discuss options and lead times.

The door features three multi-point EPDM gaskets that ensure superior sealing and significant acoustic protection. The combination of quadruple-glazed triplex glass and the three-point sealing system effectively reduces external noise and vibrations, creating a quiet and comfortable indoor environment.

The door is constructed from aluminium profile with 3 mm thickness in the core, a frame depth of 80 mm and total leaf depth of 92 mm. The core is insulated with a 34 mm articulated thermal break for optimal energy efficiency. For finishes, the door is available in standard paint, natural veneer or laminate – select according to aesthetic preferences and durability requirements.

The door is installed in a frame which is fixed to the masonry opening using specific anchors. Compatibility with different masonry types (brick, concrete, stone) depends on frame thickness and adapted fixing methods. The 80 mm frame depth suits most standard openings, but we recommend consulting an installation specialist to evaluate your specific site conditions.
