Aluminium exterior door L700 made to order

L700 exterior aluminium door with exceptional thermal insulation (Ud 0.85 W/m²K) and quadruple glazing for superior climate control and comfort.

The L700 door represents the premium solution for external access points that reconcile strict structural requirements with contemporary aesthetic expectations. Profiled in aluminium with a total depth of 92 mm, the system incorporates an articulated thermal break of 34 mm that arrests heat transfer without compromising design fluidity. The 80 mm frame depth integrates discreetly into standard masonry, permitting generous openings without consuming interior space. This is construction designed for applications where insulation and long-term performance are non-negotiable.

The quadruple glazing—configured as 44.1 triplex / 5 mm Satinato / 44.1 triplex—neutralizes both thermal transfer and unwanted acoustic penetration. Each triplex glass layer delivers rigidity and mechanical protection, while the central Satinato layer ensures thermodynamic uniformity and solar radiation control. Three strategically positioned EPDM seals within the profile maintain perfect weather-tightness under any meteorological condition, from powerful winds to extreme thermal fluctuations. The 3 mm aluminium is treated to resist corrosion and oxidation, guaranteeing structural integrity across decades of exposure.

Thermal performance certified by ift Rosenheim (Ud 0.85 W/m²K) positions this door at the level of reference closure systems worldwide. This significant value translates directly into reduced annual building energy consumption, lower heating bills, and stable interior temperature regardless of season. The acoustic insulation delivered by the multi-chambered glazing and profile system reduces external noise to levels that guarantee residential and commercial tranquility.

Flexible dimensioning—1200×2500 mm for single leaf and 1100×2300 mm for dual configurations—permits adaptation to standard openings or complex architectural requirements. The system accepts surface treatment personalization: matte finishes, decorative anodizing, or any colour reflecting the home's identity. The mechanical resilience of the aluminium profile guarantees longevity even in coastal or demanding urban environments with significant exposures.

Recommended for primary entrances to modern dwellings, access to commercial spaces where thermal and acoustic insulation are paramount, and any application where interior climate control and premium sealing are essential. Compatibility with radiant floor heating systems permits integration into complete and automated climate solutions. Investment in the L700 translates to enduring comfort, energy security across decades, and a distinctive architectural presence.

The L700 door achieves a thermal coefficient Ud of 0.85 W/m²K, certified by ift Rosenheim — top-tier performance for aluminium exterior doors. This means superior heat retention and reduced energy consumption over time. The performance is guaranteed by the quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 Triplex) and the articulated 34 mm thermal break in the aluminium profile.

The L700 door features a robust construction with 3 mm aluminium profiles and a total leaf thickness of 92 mm, including insulation spaces. The system has a total depth of 92 mm, with a frame depth of 80 mm — proportions that guarantee rigidity and optimal sealing. The quadruple glazing is integrated with precision into this structure, providing multi-level protection.

The L700 door is equipped with 3 EPDM gaskets that create multi-point sealing around the leaf and frame. This ensures superior airtightness and significant reduction of air and water infiltration. EPDM gaskets are durable and resistant to temperature variations, maintaining performance over the long term even in extreme weather conditions.

The L700 door offers flexible sizing options: in standard configuration up to 1100×2300 mm, and for single leaves up to 1200×2500 mm. For custom dimensions outside these parameters, consultation with the showroom is recommended — adaptation to specific project requirements is possible. Any customization is documented and executed according to quality standards.

The L700 door requires professional installation to ensure optimal alignment and sealing. Frames must have a minimum depth of 80 mm and must be square and flat. Masonry must be reinforced and properly treated before installation. The use of anchor brackets and sealing mastic is recommended to ensure thermal system integrity and prevent infiltration. Compatibility with existing masonry should be assessed in advance.

The L700 door in aluminium requires minimal maintenance: annual cleaning of the profile and EPDM gaskets with water and neutral detergent is sufficient. Natural aluminium resists corrosion due to its natural oxide layer. The quadruple glazing requires no special treatment, just regular washing. The thermal break and EPDM gaskets remain stable and functional for decades if not exposed to severe mechanical impact. Periodic airtightness checks are recommended.
