Single & Double Hung Window

Single & Double Hung Window

We’ve updated this classic window design and turned it into an efficient, high performance product. Our single hung version features a fixed top sash and an easy-tilt bottom. On the double hung, both sash tilt in for easy cleaning.

Our aluminum clad wood single and double hung windows have a maintenance-free heavy duty extruded clad exterior and a beautiful wood interior protected to the core against wood rot by our patented CoreGuard. Our concealed wood jambliner is a big upgrade over other manufacturer's vinyl version.
