Single-hung windows look nearly identical to double-hung windows, but only the bottom sash operates — the top sash is fixed in place. This simpler mechanism means fewer moving parts, which can translate to a lower price point and less maintenance over time. Single-hung windows still deliver excellent energy efficiency and are available with tilt-in sashes for easy cleaning. They’re one of our most popular replacements because they provide a clean, traditional look at an exceptional value.
