The Delden DTR 1748 is probably the companys best garage doors. The dual steel panels have a galvanized 25 gauge external panel and a 27 gauge interior panel that sandwiches 2 inches of polyurethane insulation. This gives the door a very energy efficient R-value of 15 plus. Installing a Delden Garage Doors of this quality will mean that you will save significant energy if you planning to heat or cool your garage. You will certainly find that your workshop will be comfortable no matter what the weather is outside. These garages will cost you more money but in our opinion they are worth it.
With a torsion type of spring, the energy is imparted or removed by rotating the spring clockwise or counter clockwise depending upon the direction of usage. With professional installation, the complete loading of the torsion spring is controlled by the garage installer, and is determined by the weight and size of the garage door that it is operating. When this type of torsion spring fails, it remains attached and intact to the location on the horizontal control rod where it was mounted. I have not heard of or seen any torsion spring fly across a garage, creating injury from failed components as with the stretched older style garage door springs. This is not to say that injuries have not occurred with the torsion style spring. The installation of this type of spring is generally safe when left to a trained garage door installation professional. Severe and serious injuries have occurred when untrained, unqualified individuals have attempted to install or service this type of spring.
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.
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.
