Aluminum alloy top-hung window

Aluminum alloy top-hung windows feature specialized hardware hinges that allow the sash to tilt outward (or inward) toward the top. When opened, the top edge remains fixed while the bottom edge slides outward, forming a triangular ventilation opening that gradually widens from top to bottom. This opening mechanism combines safety, rain resistance, and superior ventilation and airflow—even during rainfall, water is less likely to drift indoors. Additionally, the tilted opening angle makes external climbing and intrusion difficult, offering good anti-theft performance. Constructed from aluminum alloy profiles, the window frame features a sturdy structure and excellent sealing. It occupies no indoor or outdoor space, making it particularly suitable for high-rise buildings, bathrooms, kitchens, and areas requiring continuous ventilation while protecting against wind and rain. It represents a smart balance between “invisible protection” and comfortable ventilation.
