Sierra Pacific H3 Fusion Double Hung Window

Did you know?

A double-hung window has two sashes that are stacked, allowing the window to open down from the top and up from the bottom. The sashes are the parts of the window that hold the glass panes, and can be designed to tilt in for easy cleaning from inside your home.
