Built into every Western Window Systems Performance Line aluminum moving glass wall and window is the belief that your design ideas and preferences, not energy or structural limitations, should determine the look of your project. The Performance Line addresses energy and structural requirements while promoting the thin profiles and large expanses of glass that have made Western Window Systems a centerpiece in so many homes. We put the control in your hands so the product you have in mind can be the product you see in the finished design.
Say hello to an aluminum door and window line created to compete with wood products in every way. With its narrow sightlines, thermal technologies, and durability, the Performance Line from Western Window Systems allows you to meet stringent energy and structural needs while providing an unlimited number of design possibilities and a contemporary aesthetic.
