In response to the inherently dangerous old style garage spring issues as above a newer and safer system for opening the overhead garage door was created. The idea was to transfer the load or weight of the door via a cable and pulley system to a vertical rod now equipped with a torsion (twisted) spring. This type of spring is installed with specialty hardware and bolts to a fixed plate at one end while the entire spring is installed around a horizontal pipe. This load balancing device is normally installed directly over the header of the garage opening. Using appropriate cables connectors and pulleys the weight of the garage door is transferred into the torsion spring system. The difference between the old style stretched spring and the newer torsion spring is the way that the spring energy is stored. With the old style stretched spring the energy is stored and released by pulling on the spring or returning the spring to its un-stretched condition.
They are available as a prefabricated kit or built as a custom design to complement the dacor of any building. Commercial warehouse type installations often dictate higher security requirements. A good choice for this security type of door is the "roll-up" style that resembles a roll top desk type of door. This door can be manufactured with a variety of materials that can be as strong as the adjacent walls making forced entry through this opening very difficult. Other common commercial installations include light weight aluminum single or sectional panel doors. These doors function more for closing off an already secured area than for assuring point security.
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.
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.
