Double-hung windows differ from single-hung in that they offer the homeowner the ability to open each window, rather than just the bottom sash. Plus, the sash can be opened at a tilt. This allows for much better air flow and ventilation, since the sash can be angled according to the elements outside.
The ability to tilt and open each sash makes cleaning easier, too. Homeowners living off of the ground level are able to tilt the glass inward and clean each side of both panes of glass without needing special equipment or a professional cleaning company to do the chore for them.
Double-hung windows can offer homeowners added security. Many of our double-hung windows feature two locks, whereas single-hung windows feature just one. Double-hung windows also have a stronger frame and sash members because both sashes operate.
