How it works
The single hung window has two horizontal sashes. Two options are available when opening this window. Firstly, the single hung from bottom to top, is the most popular. Secondly, the double hung, from top down and vice versa, is very pratical for wind circulation and cleaning purposes.
This window has an Energy Star® rating surpassing the industry standards. However, the double hung window is less efficient since there is no fixed portion that prevents air from flowing through, due to its dual opening motion.
The hung window, is the easiest window to clean. It's latch system that folds inward is the perfect system for hard to access areas.
This window is provided with an automatic lock when closed, for added security.
