Canopy
Up & over garage doors are the most popular and straightforward garage door mechanism available. Comprising a single panel door which protrudes horizontally from the roof of the garage once raised, it forms a canopy. It moves up and over the entrance to the garage, hence 'up & over garage doors'.
The main advantage of this style of garage door and mechanism is that it allows for the maximum width for access to the garage. It is also possible to automate this style of garage door.
Movement of the garage door is assisted by strong springs, although the typically manual nature of this door means that it is normally limited to around 8ft / 2.5m width.
