1. WHAT ARE FIXED WINDOWS?
Fixed windows cannot be opened. Generally, there is no sash, and glass can only be fixed on the window frame. They are only adopted for lighting and viewing purposes without considering ventilation. As the window sash is fixed, the glass area can be slightly larger.
2. WHAT ARE CASEMENT WINDOWS?
A hinge is installed on one side of the casement window sash to connect with the window frame. There are single sash and double sash, which can be opened inward or outward. The inner opening is an easy-to-clean window, and the outward opening window sash has good waterproof performance and does not occupy indoor space when opened. The casement window has a simple structure, good sealing performance, convenient production and installation, good wind and ventilation effects, and is the most widely used.
