The Ultra Patio Door Sliding and Swinging Collections from Window City allow you to invite the outdoors into your home. Our Sliding and Swinging collections are designed to provide the strength and durability you need in your doors. Sliding patio doors do not swing and require less floor space allowing you to place furniture nearby. A swinging patio door is hinged on the sides and has two movable door panels that swing open from the sides, or you can choose from one moveable and one fixed panel for simple elegance. Patio doors are not just for patios these days, they are at home in any room. They are available in several styles and designs to match the architecture of your home.
