Light yet strong, aluminum frame windows and patio doors can be configured into a wide variety of combinations. The narrowness of the frame places the focus on the glass and subsequently, the view it offers. Multi-panel glass walls are often made with aluminum frames to facilitate indoor/outdoor living. Milgard aluminum frames are available in anodized or baked-on finishes for long lasting color. Sealed, mechanically joined corners stay square and true over years of use.
