Frequently asked questions
Are single-hung windows energy efficient?
Efficiency depends more on the glass package and installation quality than on style, though casement and awning windows seal especially tightly.
What’s the difference between single-hung and double-hung?
On a single-hung window only the bottom sash moves; on a double-hung both do. See single-hung vs double-hung.
