Single-Hung: Single-hung windows have two sashes, but only the bottom sash is operable and moves vertically. The top sash remains fixed in place, while the bottom sash slides up and down for ventilation.
Double-Hung: Double-hung windows feature two sashes that can both move vertically. This allows for more versatile ventilation options, as you can open the top sash, the bottom sash, or both at the same time. Opening both sashes slightly can create a convection effect, drawing cool air in from the bottom and letting warm air escape from the top.
Traditional Aesthetic: Single-hung windows have a classic, traditional look that complements a wide range of architectural styles. They are commonly found in older homes and buildings but are still popular in new constructions for their timeless appeal.
Energy Efficiency: Since the top sash is fixed and doesn’t move, single-hung windows tend to have fewer points of air leakage compared to double-hung windows. This can make them slightly more energy-efficient, as there are fewer opportunities for drafts to enter the home.
Ease of Cleaning: Many modern double-hung windows are designed with tilt-in sashes, allowing the panes to be tilted inward for easy cleaning from inside the home. This feature is particularly convenient for windows located on upper floors, as it eliminates the need for exterior ladders or special cleaning tools.
