Aluminum Vertical Sliding Window Strong and Durable Construction: Built with a 7 cm (2 3/4 inch) wide, quality aluminum frame for lasting strength and rigidity. The frame resists wear and maintains its structural integrity over time, even in demanding environments. Safe and LongLasting Glass: Features 5 mm thick tempered glass that offers safety. In the event of impact, the glass will not break into sharp, dangerous shards, reducing risk of injury. Smooth Vertical Operation: Doubletrack design ensures effortless opening and closing. The upper pane remains fixed while the lower pane slides inward, allowing easy adjustment for ventilation and comfort. Windproof Performance Reliable Weather Resistance: Equipped with EPDM rubber seals and strength thermal break aluminum profiles with a multichamber structure for enhanced insulation. Stable in Harsh Conditions: The robust frame and sealing system maintain shape and performance even in strong winds or continuous severe weather, preventing deformation and ensuring protection indoors. Optimized for Basement and Small Spaces Enhanced Natural Light: The large tempered glass panes maximize sunlight penetration, brightening interior spaces where daylight is limited. Controlled Ventilation: The sliding design allows fresh air to circulate without fully opening the window, making it ideal for basements, utility rooms, or compact workspaces. Easy Installation ReadytoInstall Package: Each unit includes the tempered glass window and a screw kit for quick setup. Fast, Secure Fit: Simply insert the frame into the prepared opening, secure the frame with screws, and seal edges with foam adhesive to achieve a tight, weatherproof seal in minutes. Practical Applications 1. Basement ventilation in residential homes to reduce dampness and improve airflow. 2. Utility or storage rooms where extra light and controlled air circulation are needed without compromising security. 3. Workshop or garage spaces to let in daylight and maintain a comfortable environment while protecting against wind and weather.
