Aluminium exterior door L929 made to order

from3255 € + VAT

Aluminium entrance door model L929, ift Rosenheim certified with thermal coefficient Ud=0.85 W/m²K. Premium solution for external applications with advanced insulation and quadruple glazing.

Model L929 is a high-performance external access solution engineered for properties requiring advanced thermal and acoustic insulation. The 3 mm aluminium profile combined with an articulated 34 mm thermal break creates exceptional structural behaviour, validated through ift Rosenheim testing protocols. This system's strength lies in merging aluminium's robustness with the climatic protection necessary for primary entrances.

Construction features a 92 mm total system depth and 80 mm frame profile, ensuring secure installation and durable sealing integrity. The quadruple glazing—comprising 44.1 triplex exterior pane, 5 mm Satinato centre panel, and 44.1 triplex interior layer—delivers thermal efficiency of Ud=0.85 W/m²K, a remarkable value within the aluminium door category. Three EPDM gaskets along the perimeter maintain continuous protection against air infiltration and thermal loss, offering proven long-term resilience.

The declared thermal performance aligns with superior European standards for external access, safeguarding both property value and occupant comfort. The profile's mechanical resistance and support system accommodate openings up to 1200×2500 mm for single-leaf configurations, or 1100×2300 mm in standard setups, adapting the solution to any architectural requirement.

The L929's discreet design integrates seamlessly into contemporary and traditional facades. The Satinato glazing system offers subtle light diffusion while maintaining interior privacy without sacrificing transparency. Customisation options for dimensions and opening systems—hinged, pivot, or sliding—make this door a flexible element for residential and light commercial projects.

Recommended for premium residences, administrative buildings, and commercial spaces requiring reliable thermal barriers and pure aesthetics. It harmonises effortlessly with any flooring type and interior style, from minimalism to classical European design.

Frequently asked questions

An Ud value of 0.85 W/m²K represents minimal heat loss through the door — among the best performance in the premium segment. Certified by ift Rosenheim, this coefficient translates directly into lower heating consumption over time and stable interior comfort regardless of external weather variations.

The L929 profile combines a total depth of 92 mm with an articulated thermal break of 34 mm, creating an optimized barrier against heat loss. The 3 mm aluminium alloy is reinforced with internal rigid structure, maintaining shape over extended periods and ensuring exceptional structural stability and durability.

The quadruple glazing system (44.1 triplex / 5 mm Satinato / 44.1 triplex) provides superior thermal and acoustic insulation, impact protection, and enhanced security. The extra glass layers diffuse natural light evenly and significantly reduce external noise — essential for high-traffic urban locations.

Yes, this is a bespoke solution manufactured to order. Standard maximum dimensions are 1100 × 2300 mm for regular openings, but the system supports single leaves up to 1200 × 2500 mm for larger spaces. Our design team will discuss the ideal configuration based on your existing masonry and frame channels.

The sealing system uses 3 multi-point EPDM gaskets ensuring an airtight seal around the entire perimeter. EPDM is a UV-resistant elastomer that withstands extreme temperature variations, guaranteeing constant impermeability and eliminating water infiltration and draughts even in severe weather conditions.

The door installs into the existing frame channels using the 80 mm aluminium profile base. The masonry must be plumb and level, with the opening exceeding the door dimensions by at least 50 mm on each side for polyurethane foam sealing. We recommend professional installation to ensure perfect alignment and complete weatherproofing.
