Up and over garage doors
Up and over garage doors take their name from their method of operation. Usually a single flat panel set on runners on an internal track, they are lifted up vertically from the floor, where the spring loaded runners catch, pulling the entire door upwards, whilst swinging onto a flat horizontal plane against the garage ceiling. Up and over garage doors come in two main varieties: canopy and retractable. Canopy up and over garage doors tend to leave about a third of the garage door poking out of the top of the garage when opened, but afford you slightly more width in the garage interior, compared to retractable up and over garage doors, which conceal the whole door against the garage ceiling, but require additional interior tracks to complete the motion.
