Western Multi-slide Doors

The choice of builders for over two decades

Walls that disappear? It’s true. Western Window Systems’ Series 600 Multi-Slide Door features large, unobstructed rolling glass panels that stack or slide into pockets for extra wide openings that eliminate the barrier between indoors and out. These moving walls of glass expand living space, frame beautiful views, and let in fresh air and natural light.

Sealed stainless steel ball bearing rollers make the Series 600 Multi-Slide Door easy to operate, even with extreme panel weights. And it features dual-paned low-E glass to reflect heat while allowing light to pass through.
