Aluminium exterior door L291 made to order

The L291 aluminium exterior door delivers superior thermal performance (Ud 0.85 W/m²K) and maximum protection with quadruple glazing. Robust 92 mm profile and triple EPDM seals ensure complete weathertightness.

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.

The Ud coefficient of 0.85 W/m²K (certified by ift Rosenheim) ranks this door in the high thermal insulation category, suitable for demanding climates. The articulated thermal break of 34 mm combined with quadruple glazing and triple EPDM gaskets ensure superior energy efficiency and minimal heat loss.

The L291 door is available in standard dimensions up to 1100×2300 mm (standard opening) and can reach 1200×2500 mm for single leaf configurations. All intermediate sizes are manufactured to order according to your requirements and existing opening compatibility.

The door features 3 EPDM gaskets that create a complete multi-point seal across the entire frame perimeter. This ensures an impermeable barrier and maximum wind resistance, tested according to IFT Rosenheim standards. The robust 92 mm profile and 80 mm frame depth contribute to stability and perfect fit.

The structure is made from 3 mm aluminium with a total 92 mm leaf profile and 80 mm frame profile. The aluminium used is corrosion-resistant and requires no regular repainting, making it suitable for constant sun, rain, and thermal variation exposure. The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex) provides additional protection and long-term durability.

The total system depth of 92 mm (80 mm frame + 12 mm reserve) allows easy installation in standard exterior walls. The door adapts to frames made from aluminium, PVC, and timber, and installation requires precise levelling and secure wall anchoring. We recommend consulting a specialist to verify compatibility with your existing opening and masonry type.

Aluminium requires only regular cleaning with water and mild detergent to maintain appearance and functionality. EPDM gaskets are durable for 10-15 years and can be easily replaced without complete disassembly. The quadruple glazing requires no special maintenance, and the Satinato finish is easily maintained with standard cleaning. Check sealing and hinge operation annually to ensure optimal performance.
