Garage doors are designed to enclose and protect the entrances to garages and other large structures. They are available in residential, commercial, and industrial grades. Typically, garage doors are made of wood, aluminum, steel, fabric, or screen. Both insulated and non-insulated products are available. Wood garage doors are often made of pine or cedar. Aluminum garage doors are lightweight, rust-resistant products that can be painted and sealed. Steel garage doors are long-lasting and durable. Fabric garage enclosures and fabric storm panels provide privacy and weather-resistance while allowing for light and ventilation. Garage door screens admit fresh air while preventing the entrance of insects, animals, and ultraviolet (UV) rays.

Product specifications and features for garage doors include appearance, insulation, safety, materials, window design (if applicable), and spring design. Style, pattern and color determine a garage door’s appearance. Styles and patterns vary by manufacturer, but color choices often include oak, mahogany, walnut, clay, green, and gray. Although uninsulated garage doors are available, energy-efficient products are insulated with polystyrene or polyurethane foam. Polyurethane-insulated garage doors are thinner, but have a higher insulation value (R-value). In terms of safety, some garage doors are pinch-resistant, tamper-resistant, or fireproof. Counterbalance springs that hold garage doors in position in the event of spring failure are also available. With some of these products, the spring is contained inside a steel tube.

There are many types of garage doors. Choices include roller garage doors, up-and-over garage doors, sectional garage doors, and swing-hung garage doors. Roller garage doors provide smooth, vertical operation. They are designed to save space and can be used with a remote-controlled garage door opener. Up-and-over garage doors consist of a panel that tilts forward before moving into an overhead position. Double up-and-over doors are also available. Sectional garage doors are designed for car dealerships, showrooms, and other commercial facilities. They are divided into large sections and open upwards. Unlike up-and-over doors, however, sectional garage doors do not need to swing outwards in order to open. Swing-hung garage doors open like the door to a building and are hinged to the garage’s door opening. They are not suitable for short or narrow driveways.
