Insect Proof Advanced Sliding Windows Full Range Of End Hardware For 1.4mm-3.0mm Wall Thickness And Insect-Proof Function

​Functional Features
Flexible opening and ventilation: The unique hardware lifting device enables up and down lifting operations, allowing it to stay in any position. It is easy to operate and has flexible ventilation methods. Single pull up windows have only the lower fan movable for lifting, while double pull up windows have both the upper and lower fans movable for lifting, which can better meet different ventilation needs
Space saving and safety: When opened, it does not occupy additional indoor or outdoor space, making it particularly suitable for narrow and cramped spaces. The hardware is hidden between the window sashes and frames, which not only looks beautiful but also prevents children from accidentally opening it, and has higher safety when used in high-rise buildings
Good sealing performance: Inlaid sealing structures are often used between window sashes and window frames, as well as between window sashes, combined with high-quality sealing strips, which can effectively reduce heat loss, provide insulation, sound insulation, and dust prevention effects. Its air and water tightness are usually better than traditional sliding windows
