Patio Doors
Replace that old drafty hard to operate patio door with a new Window Source sliding patio door. It’s reinforced with heavy gauge steel to make it strong and durable and features a full interlocking meeting rail.
The sliding panel rides on a solid brass rolling system for easy operation. The threshold features a strong anodized aluminum sill cover to last a lifetime. You’ll enjoy the large open view from your new patio door.
Window Source patio doors come in both double and triple panel models. All double and triple insulated glass panels come with code compliant tempered safety glass in all panes.
Each door comes standard with an internal wood handle and a dual opposing lock mortise. An optional brass keyed lock is also available.
And with our LowE/Argon glass upgrade your new door carries the Energy Star certification assuring you of energy savings and comfort.
