Aluminium exterior door L701 made to order

L701 aluminium entrance door with quadruple glazing and exceptional thermal efficiency (Ud 0.85 W/m²K) for premium exterior performance.

The L701 is a premium entrance solution for contemporary projects, merging robust structural engineering with certified thermal performance. The anodised aluminium profile, 3 mm thick, integrates within a system depth of 92 mm, incorporating an articulated thermal break of 34 mm that minimises heat transfer between exterior and interior. The leaf thickness of 92 mm and frame depth of 80 mm create a structurally stable assembly, suitable for oversized apertures and variable climate exposure. This rigorous construction ensures durable weatherproofing and long-term resistance to deformation.

The quadruple glazing — composed of 44.1 mm triplex, 5 mm Satinato glass, and 44.1 mm triplex — achieves a Ud coefficient of 0.85 W/m²K, certified by ift Rosenheim. This thermal benchmark positions the door at the apex of exterior solutions, reducing heat loss and maintaining consistent interior comfort even in harsh climates. Three high-grade EPDM gaskets guarantee comprehensive sealing and protection against water and wind infiltration.

Dimensioning adapts flexibly to project requirements: standard apertures up to 1100 × 2300 mm for typical configurations, or single leaves reaching 1200 × 2500 mm for generous access points. Opening mechanisms can be customised according to functional and aesthetic demands. The anodised aluminium permits varied finishes and seamless integration with building automation and climate control systems.

Recommended for primary entrances in modern residences, offices, and commercial spaces where thermal insulation, security, and durability are paramount criteria. It pairs elegantly with premium flooring—marble, granite, designer parquet—and complements contemporary architecture through balanced proportions and clean lines, without ornamental excess.

The L701 door achieves a thermal performance of 0.85 W/m²K (ift Rosenheim certified), placing it in the superior energy efficiency class. This value is achieved through the 34 mm articulated thermal break system and the quadruple glazing (44.1 triplex + 5mm Satinato + 44.1 triplex), which significantly reduce heat loss and maintain stable indoor temperatures year-round.

The L701's quadruple glazing consists of four glass layers (44.1 triplex + 5mm Satinato + 44.1 triplex) that absorb and reflect thermal energy, ensuring superior insulation and optimal acoustics. For an exterior door, this system is essential: it prevents condensation, increases mechanical security, and reduces external noise—particularly valuable on properties near busy areas.

The L701 is available in standard dimensions up to 1100×2300 mm, with single-leaf custom orders accommodating sizes up to 1200×2500 mm. For dimensions exceeding these limits or special configurations (asymmetric openings, slopes), our showroom team recommends a technical consultation to assess feasibility and adapt the frame and anchor systems accordingly.

The L701 door has a total thickness of 92 mm (frame + core + glass), with a frame depth of 80 mm. Installation into existing brickwork is achieved through a multi-point anchor and sealing system that aligns with your wall thickness—we recommend a showroom consultation for measurement and installation detail specific to your construction type (solid brick, lightweight concrete, etc.).

The L701 door is fabricated from 3mm anodized aluminium, a durable and corrosion-resistant material ideal for exterior environments. Maintenance is straightforward: periodic cleaning with water and neutral soap, avoiding harsh chemicals; the anodized finish provides long-term protection without recoating, and the multi-point EPDM seals should be inspected annually to maintain thermal and acoustic performance.

The L701 is equipped with three multi-point EPDM seals that provide superior sealing around the entire door perimeter. The system works through progressive compression of the gaskets against frame and jamb, eliminating micro-gaps that allow water and air infiltration; this results in complete protection against driving rain and strong winds, combined with the low Ud thermal coefficient.
