Aluminium exterior door L722 made to order

Thiral L722 aluminium exterior door with exceptional thermal insulation and quadruple glazing for ultimate performance. Premium engineering for modern entrances.

The L722 exterior door from Thiral represents a high-performance solution for main entrances in modern residential and commercial buildings. Engineered with precision in Greece, this door combines the durability of aluminium with advanced thermal insulation, positioning itself in the premium segment of exterior access offerings.

The L722 profile features a total system depth of 92 mm, with a frame depth of 80 mm and a solid leaf of 92 mm thickness. The structural aluminium measures 3 mm thick, reinforced with an articulated thermal break of 34 mm, ensuring efficient separation between interior and exterior environments. The quadruple glazing (44.1 triplex / 5mm Satinato / 44.1 triplex) delivers top-tier thermal insulation, while triple sealing with EPDM gaskets guarantees protection against water and air infiltration.

The thermal performance of this door is validated by ift Rosenheim certification, with a Ud coefficient of 0.85 W/m²K — a value that positions L722 among the most efficient solutions in its class. Acoustic insulation benefits directly from the multi-layer glazing and the rigid construction of the profile. Standard dimensions accommodate installations up to 1100×2300 mm (double leaf), while single-leaf configurations extend to 1200×2500 mm, offering flexibility for diverse projects.

The L722 design reflects a preference for clean lines and balanced proportions, compatible with both contemporary and traditional architectures. The 92 mm leaf thickness and aluminium finish permit extensive colour customisation, depending on project requirements. The opening system can be adapted — hinged, sliding, or hybrid — to meet functional and aesthetic demands of specific spaces.

Recommended for main entrances of modern homes, office buildings, luxury residences, and renovation projects with high insulation and security requirements. L722 integrates seamlessly with premium flooring, radiant heating systems, and contemporary furnishings, creating sophisticated transitions between exterior and interior.

The Ud coefficient of 0.85 W/m²K (ift Rosenheim certified) places this door in the premium insulation category. The quadruple glazing — two pairs of triplex with 5 mm Satinato spacer — ensures superior thermal performance and significant acoustic damping. The 92 mm system depth and articulated 34 mm thermal break optimize performance in harsh conditions.

Frame and leaf are 3 mm aluminium with structural reinforcement, ensuring rigidity and durability for decades. Aluminium does not warp under humidity or extreme temperature swings, requires no periodic repainting, and naturally resists corrosion. The 80 mm frame depth and 92 mm leaf provide superior stability, while anodized or premium powder-coat finish maintains aesthetics effortlessly.

In standard configuration, the door reaches maximum 1100×2300 mm, and in single-leaf variant up to 1200×2500 mm. As a premium showroom product, we accept full custom sizing based on your needs, regardless of standard or non-standard masonry. We recommend direct consultation with our team to ensure perfect compatibility with existing frames and installation details.

The sealing system consists of three EPDM gaskets (ethylene-propylene-diene monomer) positioned around the entire door perimeter for multi-point protection. EPDM is a premium elastomer material that maintains its elasticity and adhesion properties over time, resisting ozone, UV radiation, and extreme temperature variations. Combined with the 92 mm profile and thermal articulation, this creates a physical barrier that completely blocks water intrusion and eliminates air gaps.

The 80 mm frame profile adapts easily to standard European masonry (typical thicknesses 60–100 mm). For non-standard situations — thicker, thinner, or specialty masonry materials (brick, concrete, prefabricated) — we offer frame extensions and adapters installed to order. Installation in any case requires consultation with our specialist to ensure proper drainage, adequate fixation, and aesthetic integration with interior and exterior finishes.

The product does not explicitly specify RC class, but construction from solid 3 mm aluminium, quadruple glazing (44.1 triplex), 92 mm system depth, and triple EPDM sealing provide significant physical resistance. To achieve RC2 or RC3 certification (burglary resistance), it can be equipped with certified security cylinders and hidden hinges on order. We recommend contacting us directly for armoring options and compatibility with modern access control systems.
