Aluminum alloy windows primarily fall into four categories: sliding windows, casement windows, inward-opening windows, and outward-shifting windows.
Sliding Windows
Sliding windows are among the most widely used aluminum alloy windows today. Key features include smooth, effortless operation and an attractive, stylish appearance that complements various architectural styles. They generally come in single-sliding and double-sliding configurations, allowing for choices based on interior space and personal preference.
Casement Windows
Casement windows open either inward or outward. Compared to traditional wooden windows, they are lighter, sturdier, easier to maintain, and offer a longer service life. They provide excellent natural light and ventilation, making them particularly suitable for small apartments and spaces where good airflow and lighting are essential.
Inward-Opening Windows
These windows open by tilting or swinging inward along a vertical axis. They are easy to operate and aesthetically pleasing, making them an ideal choice for compact areas like balconies where space is at a premium.
Outward-Shifting Windows
Outward-shifting windows operate via sliding brackets and an outward-pushing sash. They take up minimal interior space-thereby better protecting indoor furniture and décor-and are easy to clean. They are suitable for balconies or areas with limited interior space, such as elevator lobby windows or bar-counter windows in restaurants.
