The primary feature in Double Sliding Windows is that it has two sashes, framed side by side and functions with both sashes sliding horizontally. Double Sliding Windows are versatile and create a viable alternative for space restrictions, where the width exceeds the height of the opening. Double Sliding Windows typically come in two panels, however they are also available with three panels. Double Sliding Windows are sometimes referred to as "Sliders" or "Gliders". Double Sliders also allow both panels to open simultaneously, creating cross ventilation.
