What is a Patio Door?

Sliding patio doors, also known as gliding doors or sliding glass doors, are found in many homes.  While a French door swings in or outward, the operating glass panel of a sliding patio door glides on rollers on a track.  This convenient design provides great ventilation since the operating panel stores completely out of the way when in the open position.

What Patio Doors are Available at The Window Source?

Window Source patio doors come in double and triple insulated glass panels and come with code-compliant tempered safety glass. The vinyl gliding panel frames are reinforced with heavy-gauge steel to make your door strong and durable.

The sliding panel glides on a solid brass rolling system for ease of operation. The doorsill features a strong anodized aluminum sill cover designed to last a lifetime.  Each door comes standard with white or beige handles. Optional brass, satin chrome, or oil-rubbed handles are also available. And with our LowE/Argon glass upgrade, your new door carries Energy Star certification which assures you of energy savings and comfort.
