What is a patio door?

This 2 panel sliding patio door is shown in white with brass hardware

Sliding patio doors also known as gliding doors and sliding glass doors are found in almost every home. They have a similar appearance but operate differently than a French door which swings in or outward. The operating glass panel of a sliding patio door glides on rollers on a track in the sill. This design provides great ventilation with the operating panel stored completely and safely out of the way when in the open position.
