Premium quality
This window model is equipped with high-grade imported hardware and features a minimalist design with the sash enclosed by the frame. Each joint is sealed with waterproof glue and then pressed with a trim line, which not only looks good but also prevents water leakage, making the window more airtight and leak-proof. The integrated ultra-high water-blocking edge serves both sealing and waterproofing functions, and also has a shading effect.


It is unique in the industry that the track is internally connected with felt strips, which effectively seals and prevents dust. The solid support track has a strong load-bearing capacity and eliminates the problem of water flowing inside the profile cavity.
The umbrella-shaped track extension edge structure has strong support and fits well with the window sash felt strips, providing excellent sealing performance. The high and low drainage structure is more reasonable in design and has a large drainage capacity, preventing rainwater from flowing back. The patented key-locked lock can effectively prevent children from opening it by mistake, ensuring safety.


Waterproof adhesive process
Each connection interface is equipped with a waterproof sealant process. After injecting the sealant and pressing the wiring, it is aesthetically pleasing, preventing water leakage issues and making the window more sealed and waterproof.
Double-sealed rubber strips for the frame setting
The sealing strips are integrated into the frame, which effectively protects the strips. Additionally, the double mesh strip connection design ensures excellent sealing performance. Moreover, during the closing process, it also serves as a shock-proof and quieting mechanism.
anti-wind device
The window sashes are equipped with sealing and shading blocks to prevent light leakage and air leakage between the two middle sashes. They also serve as a shock absorber
