Tandong Doors & Windows Wins 2025 French Design Awards

Good news arrives with spring, bringing well‑deserved glory. Recently, the highly‑anticipated 2025 French Design Awards winners have been officially announced! Tandong Doors & Windows’ Lizun 80 Ultra‑Narrow‑Frame Concealed‑Sash Window stood out from over ten thousand top‑tier entries worldwide with its forward‑thinking design concept of “ultra‑narrow aesthetics × functional innovation” and breakthrough hard‑core technologies, winning the Silver Award of the 2025 French Design Awards.

The French Design Awards was founded in 2015 by the International Awards Associate (IAA). It aims to provide a broader platform for global designers to convey their design philosophies, showcase outstanding design works, and lead worldwide design innovation.

Against such stringent evaluation criteria, Tandong’s Lizun 80 Ultra‑Narrow‑Frame Concealed‑Sash Window earned this world‑class honour through outstanding strength. This achievement is not only international recognition of Tandong’s product design capability and comprehensive innovation strength, but also demonstrates to the world the pinnacle level of Chinese intelligent manufacturing in the high‑end door‑and‑window sector.

A Ground‑Breaking Creation, Redefining Traditional Window Craftsmanship

Tandong’s Lizun 80 Ultra‑Narrow‑Frame Concealed‑Sash Window reconstructs visual boundaries with ultra‑slim frames, responding to contemporary residential aesthetic demands with ultimate minimalism. Featuring a concealed main‑sash structure, the frame and sash sit perfectly flush like a mirror, eliminating redundant visual elements and delivering unobstructed panoramic views. Constructed from premium 6060‑T66 raw aluminum alloy with wall thickness of 2.0‑2.5 mm, exceeding national standards, its structural strength is boosted by 30%. Boasting superior wind‑resistance and corrosion‑resistance, it builds a solid safety barrier for homes.

Exquisite Details, Embracing High‑End Residential Philosophy

Fitted with German WEHAG hardware system, the window opens and closes smoothly and silently, with a load‑bearing capacity twice higher than national standards, easily supporting extra‑large window sashes. Equipped with widened 30 mm nylon thermal‑break strips and automotive‑grade EPDM sealing weatherstrips paired with equal‑pressure welding technology, it achieves 40 dB noise reduction and 50% improvement in thermal insulation and energy efficiency. The perfect integration of function and art creates living spaces that combine practicality with premium quality, redefining the elegance and style of modern homes.

Tandong Doors & Windows’ victory at the French Design Awards marks not only a triumph of design and technology, but also a milestone for Chinese intelligent manufacturing stepping onto the global high‑end stage. From concealed‑sash innovation to constant temperature and quiet comfort, from German‑engineered craftsmanship to panoramic vistas, we break boundaries with craftsmanship and reshape residential aesthetics through innovation. Moving forward, Tandong will keep taking innovation as our blade and quality as our shield, writing more legends of Chinese design on the global stage.
