Alexandrin Garage Doors October 17th, 2017 - 20:33:42
I have been involved in numerous garage door lawsuits where many different reasons for an injury have occurred. Having been retained as expert witness for both plaintiff and defense several common factors have been observed. In many cases unqualified individuals have attempted to repair or install garage doors. They have lacked the knowledge skills or even the basic required tools to perform the work safely and properly. I have been hired as an expert by garage door manufacturers and installers to defend claims that they are not responsible for alleged product defects. In most cases the components that failed failed as a result of abuse or improper installation on the part of the end user. As stated above the installation of many garage doors is not appropriate for an untrained person.
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.
In most installations a warning tag is left attached adjacent to the torsion spring when the garage door is installed. This tag warns of the danger associated with the stored energy of this spring and alerts untrained individuals to not attempt any repair adjustment or to even touch the spring and associated hardware. When the label that should be attached to this spring becomes damaged is removed or tampered with it is important that a new warning label be reattached immediately to show the dangers of this spring tension
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.
