Advantages of sliding windows include ease of operation, unobstructed views, and flexible design options. This type of window is popular in contemporary architecture and is used when the home’s design has more horizontal space than vertical. A sliding window can be operated by sliding left or right within a single frame. Both sides can be opened simultaneously, allowing for complete control of the room’s ventilation. When fully open, a sliding window can be stacked or hidden in a pocket in the wall.
