Chuanggao Windows & Doors creates ultimate daylighting vision. The Yuehua T1 system double inward-opening casement windows make a stunning debut!
Most homebuyers prioritize properties with excellent natural lighting and pleasant outdoor views. However, to enjoy beautiful scenery every day, apart from the inherent landscape advantages of the residence, the lighting performance and transparency of windows also play vital roles. To meet homeowners’ pursuit of an ultimate viewing experience, Chuanggao Windows & Doors has launched its new-generation system window product this year — the Yuehua T1 Double Inward-opening Casement Window.

The standout feature of the Yuehua T1 model lies in its high light transmission and wide-view design, creating a vivid viewing space that embraces scenery across all seasons for residential spaces. Adopting an ultra-narrow slim frame design, this new window features externally installed glazing beads. No bead splicing traces of sashes can be seen indoors, delivering an unobstructed and brighter panoramic view.
Relevant principals of Chuanggao stated that the brand has long maintained stable cooperation with Xinyi Glass, a renowned comprehensive glass manufacturer in the industry, and this new product also adopts its high-quality glass materials. Xinyi Glass boasts smooth surface and a light transmittance close to 90%, making it an ideal raw material for floor-to-ceiling windows.

Equipped with large insulated glass of 5mm+27A+5mm specification, the Yuehua T1 window ensures superior light permeability. Residents can bathe in morning sunlight and enjoy bright moonlight at night, with mountain and lake scenery fully in sight. Inert gas is filled inside the insulated glass, which not only guarantees ample daylighting, but also effectively improves sound insulation and thermal insulation performance.
Apart from outstanding viewing effect and daylighting performance, the Yuehua T1 Double Inward-opening Casement Window is equipped with powerful practical functions. According to the R&D team, it adopts an innovative four-seal casement window structure (National Invention Patent No.: ZL202211672268.0), greatly enhancing water tightness, air tightness and sound insulation. Breaking the traditional three-cavity structure, it applies a five-cavity structure matched with 44mm multi-cavity thermal insulation strips, which significantly upgrades heat preservation and insulation performance, perfectly suitable for cold regions in autumn and winter.

In response to growing consumer demand for window safety, the R&D team has optimized numerous safety details in design. The window is made of aviation-grade aluminum profiles with a wall thickness of 1.8mm, featuring high rigidity, firm structure, excellent corrosion resistance and aging resistance. It adopts professional glue-injected corner connectors together with zinc alloy reinforcing parts, optimizing waterproof performance and corner structural strength to ensure overall window stability.
Furthermore, this model is designed as a safety-type casement window (National Utility Model Patent No.: ZL202222906896.2). It is fitted with complete sets of German WIHAGEN locking hardware and brand-matched heavy-duty inward-opening & tilting hinges for solid durability. Equipped with key-controlled screen window locks and split glass guardrails, it ensures safer and more comfortable use, especially ideal for families with young children.
Homeowners who have installed this product confirm that it delivers ultra-wide views with convenient and safe daily use. Currently, the Yuehua T1 Double Inward-opening Casement Window is available at all offline flagship stores of Chuanggao Windows & Doors across the country. Interested customers are welcome to experience it in physical stores.
