Aluminium exterior door L730 made to order

Thiral L730 aluminium exterior door with exceptional thermal insulation (Ud=0.85 W/m²K) and quadruple glazing for superior security and comfort.

The Thiral L730 exterior door represents a premium entrance solution engineered for modern residences demanding high-performance thermal efficiency. The aluminium profile, available in dimensions up to 1200×2500 mm, integrates seamlessly into contemporary façades with impeccable architectural proportions.

The door construction features a 3 mm aluminium profile paired with an articulated 34 mm thermal break that ensures superior insulation between exterior and interior frames. The system's total depth of 92 mm, with an 80 mm frame, enables rapid and secure installation across various wall configurations. The quadruple Satinato glazing — with 44.1 mm triplex layers on each face — delivers controlled transparency and significant acoustic protection, while triple EPDM gaskets guarantee durable sealing against wind and rain.

Thermal performance certified by ift Rosenheim, with a Ud coefficient of 0.85 W/m²K, positions this door in the premium segment for both retrofit and new construction, delivering proven benefits in annual energy consumption reduction. The structural resilience of the 3 mm aluminium profile ensures long-term stability, even in areas exposed to high winds or extreme weather conditions.

The L730 version permits flexible dimensional customization, with swing or sliding opening options tailored to spatial requirements. The system can be configured as a single door, double door, or with a side window, offering diverse architectural solutions for primary entrances or secondary garden access.

Recommended for contemporary residences, villas with high insulation requirements, and renovation projects where energy efficiency and modern aesthetics are paramount. It pairs seamlessly with matching window series for complete visual continuity on the building façade.

The L730 achieves a Ud value of 0.85 W/m²K (ift Rosenheim certified), placing it in the premium thermal insulation category. This performance stems from the 34 mm articulated thermal break and the quadruple glazing system (44.1 triplex / 5mm Satinato / 44.1 Triplex), which substantially reduces heat loss and delivers superior acoustic comfort.

The L730 is constructed with an aluminium profile of 3 mm thickness and an insulating core with a total thickness of 92 mm. The system has a total depth of 92 mm, with a frame depth of 80 mm, and features a 34 mm articulated thermal break ensuring optimal thermal separation between outer and inner profiles. Quadruple glazing and multi-point sealing complete the insulation system.

The L730 is available in standard dimensions up to 1100×2300 mm for dual-leaf systems and up to 1200×2500 mm for single-leaf configurations. All dimensions can be custom-adjusted to perfectly fit your building geometry, ensuring precise installation into existing frames without structural modifications. We recommend consulting our design team for extreme sizes or special configurations.

The L730 uses a multi-point sealing system with 3 high-density EPDM gaskets, ensuring complete protection against water and wind across the entire frame perimeter. The gaskets are strategically positioned within the 80 mm frame depth to prevent infiltration, even under heavy rain and strong wind conditions. The system is tested to European standards for durability and long-term weather resistance.

The L730, with its 92 mm total depth and 80 mm frame width, is designed for seamless integration into standard frames and common masonry variations. Compatibility depends on the size and condition of the existing frame — we recommend precise measurement and professional consultation to confirm whether minor masonry adjustments are needed. For installation in exterior-insulated walls or non-standard conditions, our team can adapt the installation details.

The L730 requires minimal periodic maintenance due to its durable aluminium profiles and robust quadruple glazing. Quarterly cleaning of EPDM gaskets with neutral water and soap, followed by rinsing and drying, is recommended. For aluminium surfaces, use metal-specific cleaning products, avoiding abrasive agents. Inspect gaskets annually and replace if deterioration is detected, to maintain seal integrity and thermal performance over time.
