The L291 exterior door represents a high-performance solution for primary access points to the outside. Engineered from premium-grade aluminium, this swing door combines modern elegance with exceptional weatherproofing, making it ideal for residential and commercial applications in temperate and continental climates. Its position in the upper segment of aluminium door ranges recommends it to owners who prioritize thermal efficiency and long-term durability.
The system profile, with a total depth of 92 mm, is reinforced by an articulated thermal break of 34 mm that interrupts heat conduction between exterior and interior zones. The 3 mm aluminium leaf construction delivers exceptional rigidity, while triple EPDM gaskets on three sides create impermeable seals. The quadruple glazing (44.1 triplex / 5 mm Satinato / 44.1 triplex) combines strong thermal insulation with subtle visual privacy, protecting the interior from noise and extreme temperatures. Maximum opening capacity of 1200×2500 mm for a single leaf offers design flexibility for diverse spatial configurations.
Certified thermal performance of Ud 0.85 W/m²K (according to ift Rosenheim testing) places it among the finest aluminium doors, significantly reducing heating and cooling costs. The three-gasket EPDM system and 92 mm leaf thickness ensure resistance to weathering, wind pressure, and water infiltration, even in harsh climatic conditions. Robust construction guarantees smooth, quiet operation and durability spanning decades with minimal maintenance requirements.
The L291 accommodates broad customization in standard and oversized dimensions, with an 80 mm frame depth that fits any wall thickness. The traditional swing opening system adapts seamlessly to orientation and functional preferences. The aluminium finish allows for an extensive palette of colours and surface treatments, from neutral tones to warm or metallic hues, enabling harmonious coordination with walls and façade elements.
Recommended for primary entrances, modern building façades, commercial spaces, and residences requiring maximum protection and energy efficiency. Integrates perfectly with solid wood flooring, parquet, or tile, equally suited to minimalist, contemporary, or classical interiors. Pairing with other aluminium elements (windows, sliding systems) creates aesthetic and functional coherence.
