This is one of the most popular types of the up and over garage doors. They are mostly up to a total of 8 feet wide. There is a torsion spring that is usually above the garage door which are usually made specifically so as to lift the door via the conical drums and steel cables that are usually attached at the end of the specific spring. The heavier and wider garage doors which are over 8 feet are usually operated using a retractable gear because they are usually too heavy for the canopy mechanism. Canopy doors are one of the easiest and the quickest doors to install and they also have the advantage of providing the full drive through width when it is open, unlike the retractable mechanism which is a different case. This type of door also has the advantage of been made remote controlled. However, there may be additional equipment as well as a motor for this to be possible making it more expensive based on http://www.bgd.net.au/.
