5 Garage Door Exhaust Port - As a door expert witness, I am called upon many times annually to gauge garage door injuries. Garage doors come in many shapes and sizes. Their functions vary from basic security of an area to concealment that is decorative. Most doors might be broken down into a few basic styles or groups. Typical contemporary garage doors for residential applications tend to be mainly of the overhead sectional variety. That style of the door comes in levels of insulation, many configurations, substances, plus a wide range of appearance options.
They have been built as a custom layout to complement the decor of any building or available as a kit that is prefabricated. Higher security demands are commonly dictated by commercial warehouse sort installations. A great option for this security type of door is the "roll-up" style that resembles a roll top desk type of door. This door can be made with many different substances that may be as robust as the walls that were adjoining, making forced entry through this opening very hard.
Before, the biggest concern with operating an overhead garage door was the possible hazards associated with the springs useful for balancing the door weight. Pre mid-1960's garage door installations commonly relied upon some of stretched (tensioned) springs to aid the operation of the garage door pivoting hinges. Unloading (releasing) of the stored spring energy happened as the door was opened to the horizontal overhead position.
One of the very dangerous aspects of the spring systems was that after a period of time, often without any care or review, the points of attachment of the springs would corrode or become feeble. This weakening of the springs or points of attachment would often result in an inadvertent failure fling that is explosive the broken spring parts across the garage, embed the spring or steel parts into the garage walls, cars or other things in the route of traveling.
