What type of window is commonly used for horizontal sliding mechanisms?

Horizontal sliding windows are designed specifically to operate along a track mechanism, allowing them to open horizontally by sliding side to side. This type of window is characterized by its two or more sashes that can be moved left or right, providing ease of operation and adaptability for wider openings.

In contrast, the other types of windows serve different functional designs. Double-hung windows are designed with two sashes that slide vertically. Casement windows are hinged on one side and open outwards with a crank mechanism. Fixed windows, as the name implies, are stationary and do not open at all. Thus, the unique design of horizontal sliding windows makes them the appropriate choice for operations requiring a horizontal mechanism.
