Single Hung Windows
Single hung windows, often referred to as vertical sliders, feature a fixed top sash while the bottom sash slides upward. The bottom sash can tilt inward for easy cleaning, making these windows an excellent choice for tall, narrow openings. They are a classic window style in North America, combining traditional aesthetics with practical functionality.
While they effectively keep out drafts and weather, single hung windows are not as energy-efficient as casement or awning windows. With double-glazed sealed units and smooth vertical operation, they offer durability, ease of use, and a timeless appearance suitable for many home styles.
