Canopy Doors: When a canopy door opens it swings outwards and then slides upwards into the garage ceiling. This leaves one third of the door outside the garage. The security of the door is enhanced as the pivot points are located down the door. These doors are easy to install as no tracks are required inside the garage and the entire door mounts to the door frame. Canopy Doors are available in timber steel ABS and GRP. This garage door provides a good drive-through width.
In contrast to an overhead type of garage door be it sectional or single panel roll up doors have a totally different type of operating system. When these doors are used they can be concealed in an overhead or under mounted trough. These doors operate similarly to a roll top desk door except for how they are stored when not in the closed position. They normally coil as they are retracted and require significant gear trains to reduce the effort required to move these doors up and down into position. Often the forces needed to move these roll up doors require a reduction type of transmission that allows a very heavy door to be operated effortlessly. These doors can be chain driven either manually or can be automated using electric motors. Roll up doors require more frequent evaluation and servicing than a standard overhead garage door. The tracks that are mounted vertically on both sides of the garage opening need maintenance and cleaning more frequently and are often blocked by foreign obstructions or damaged by collision of some type. These roll up doors are often held open by some type of ratcheting action. Proper balancing of these doors is often more important than an overhead type of door as the weight of these type of doors is normally much greater than an overhead door.
