Topanish Door
The vertical sliding window is a specialized design that opens by sliding up and down. Commonly known as the American-style sliding window, it is highly popular for its space-saving features and efficient ventilation capabilities, differing from traditional inward or outward opening modes.
1. Single Sliding Window: The upper sash glass is fixed to the frame, while the lower sash slides vertically. This design provides superior air and water tightness.
2. Double Sliding Window: Both sashes slide independently, offering flexible ventilation and easier maintenance/disassembly.
