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.

As a door expert witness, I am called upon many times a year to evaluate garage door injuries. Garage doors come in many shapes and sizes. Their functions range from basic security of an area to cosmetic concealment. Most doors can be broken down into a few basic styles or categories. Typical modern garage doors for residential applications tend to be predominantly of the overhead sectional variety. That style of door comes in many configurations, materials, levels of insulation, and a wide range of appearance possibilities.
The Vintage Plus line of Delden Garage Doors is a very popular and affordable carriage door. The 25 gauge steel pre-painted doors are 2 inches thick insulated with polystyrene with a vinyl backing. They are reported to have an R-value of at least 6. Obviously these doors are not meant to be used in areas that have tough winters or where you are going to heat or cool your garage. One of the problems with using polystyrene insulated panels is that this type insulation leaves gaps which reduce the effectiveness of the insulation.
