A Window Like No Other.

FoldUp Windows

A window like no other.

Introducing FoldUp Windows, a unique window that creates new opportunities to open your living space to the outdoors. The window folds upward to an opening almost twice as large as a traditional double hung. Also known as fold-up windows, folding windows or pass through windows, FoldUp has the look, feel, finish, and performance of other traditional wood windows when closed.

The magic of FoldUp™ is that when open, the window sashes are out of the living space and your room can feel and act like an open porch. With screens in place, your space functions like a screen room. And when closed, our windows give you comfort and protection from even the harshest elements.
