Horizontal sliding windows provide maximum light and ventilation at the lowest cost. These windows are the easiest to clean when using the “tilting” version where the window sashes open into the room.
The Single Slider is the strongest and tightest sealing of the sliding windows as it uses a rigid meeting rail and direct glazing to hold the window square. The double slider is used primarily where cleaning is the most important criteria for replacing windows.
Both styles can be made in “lift out” or “tilt in” versions depending on the application.
