What is a Patio Door?

A patio door is a sliding glass door located on an exterior wall. It typically opens to a backyard, deck or patio, offering a pleasant view and providing fresh air and natural light. Patio doors consist of multiple panels that can be mobile to slide open. Polaris offers two, three and custom panel door options.
