Garage area may not be used by the car alone; it works as a store for inventories & old furniture or a workshop for others. You would want a door which insulates well if there is a part of house extended above the garage. The R-value on a garage door tells how well it insulates. The higher the R-value the better is its insulation properties. Terms like Headroom Backroom and Sideroom become parameters to select a suitable garage door as they determine the dimensions; Headroom is the amount of space inside the garage between the top of the garage door and the ceiling. Backroom is the inside length of the garage from front to back. Side room is the distance between the sides of the garage door and the side walls of the garage. Dimensions matter when you are installing a garage door as the hardware needs some room to operate freely.
In the past the biggest concern with operating an overhead garage door was the potential risks associated with the springs used for balancing the door weight. Pre mid 1960s garage door installations typically relied upon a pair of stretched (tensioned) springs to assist the operation of the garage door pivoting hinges. These springs became loaded (tensioned) as the door was moved into the closed position. Unloading (releasing) of the stored spring energy occurred as the door was opened to the horizontal overhead position. One of the most dangerous aspects of these spring systems was that after a period of time often without any maintenance or inspection the points of attachment of these springs would rust or become weak.
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.
