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.
Any garage door can be purchased with optional windows. A myriad of patterns and designs are now available that allow in natural light to liven up the garage. Weigh safety issues in your choice and whether the windows are made of acrylic or glass.
Some manufacturers tout the insulation value of garage doors. Most people question this concern, since the garage in most homes is neither heated nor cooled. If insulation is a concern to you, lightweight polystyrene foam insulation can be added to most doors. Insulated doors will help to reduce the amount of outside temperatures that enters your garage, thus keeping it more comfortable for you. An insulated door is generally quieter and has a more attractive interior than an uninsulated door.
