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.
Retractable Doors: This type of garage door swings outwards up and back into the ceiling of your garage. The pivot points of the doors are located at the top and this makes you unable to park your vehicle close to it. You should always ensure enough room is available on your driveway. The installation is easy. These types of doors are the easiest ones to be automated with a suitable electric opener. They provide good security to your vehicles and they are fitted with four latches. They re available in timber GRP (Glass Reinforced Plastic) steel and ABS. One point to note though is that this door provides you with a reduced drive-through width due to side spring assemblies.
