SINGLE HUNG WINDOW

A single-hung window features two sashes, but only the bottom sash moves vertically while the top sash remains fixed. This traditional style is common in many homes because it’s simple, cost-effective, and easy to maintain. It allows controlled ventilation by opening the lower half, which helps draw cool air in while warm air escapes from above. The fixed upper sash provides good insulation and a tight seal, improving energy efficiency. Single-hung windows work well in bedrooms, living rooms, and areas where you don’t need both sashes to operate. Their classic look suits traditional architecture, though cleaning the exterior of the top sash can be difficult on upper floors.
