The choice of builders for over two decades

wws_logo2x

The ability of a Western Window Systems’  Bi-Fold Door to completely open up to the outdoors is what makes it so unique. Designed to smoothly stack and fold against side walls, it creates a huge opening from corner to corner, connecting the indoors with the outside and expanding living space. Need everyday access? Opt for convenient single or double swing doors.

Thermally broken aluminum and dual-paned low-E glass make their doors energy efficient. And because it’s aluminum, it’s low maintenance, too. Sealed stainless steel ball bearing rollers allow for easy operation, even with extreme panel weights.
