Security: Because single hung windows only open in one direction, there are fewer points of failure on the window’s locking system. With only one lock, you may also be less likely to forget to lock your windows once you shut them for the day (or even for the season!).

Energy Efficiency: With only one movable sash, there is less opportunity for air infiltration as the window ages. Installing replacement single hung windows also increases the energy efficiency of your home, as newer windows feature improved technology—including more energy efficient glass, frame, insulation, and more. The less air that can infiltrate through your window, the less you should waste on heating and cooling costs year round. It can also prevent moisture getting into your home (and, therefore, decrease the risk of mold, mildew, water damage, and wood rotting).

Space Saving: Single hung windows are great to install in smaller rooms (such as studies, bathrooms, guest rooms, etc.) and areas with high traffic (entry ways, hall ways, etc.). Because they don’t open outward, they are ideal for tight spaces and allow for extra sunlight and cross breezes without losing any square footage in a room.

Cost: When comparing cost, keep in mind that each manufacturer style and material of window will differ in cost. That said, single hung windows are often more affordable than double hung windows (mostly because there are fewer moving parts).

Versatility: While they are a basic window with only one moving sash, single hung windows offer many options when it comes to style, wood, trim, shape, and finishing options.
