As a general rule, the choice of garage door and garage door material is largely determined by the type of house you have, your space, and of course, your budget.
The concept of a garage door system arrived during the Second World War. Garage Door Openers have been saving Americans from back injuries for over 35 years, yet there have been few new modifications or major innovations in these garage door openers. Believe it or not some people have voice activated garage door openers instead of you having to place your finger over the button when you walk from your house to the garage.
The reason garage door openers do not burn out is because the springs allow the door to open easily by pulling the door up so the opener has less strain on the motor, the springs also help if you need to open the door manually. Usually two types of springs are used linear expansion and tensional springs. The springs on your garage door can pose a safety hazard. These kinds of springs are installed over a shaft that helps roll the door up to the open position. Garage door springs are very dangerous, even when the garage is closed, as they contain large amounts of potential energy (that’s just waiting to be suddenly converted to kinetic energy, ie movement) and have killed or seriously injured many people.
