The new generation of garage doors is reasonably priced, safe and easy to install and they are no longer a convenience for only a select few. You should consider changing your garage door if it is too old or if it has an old motor or pulley system.
The garage doors can be selected by the type of the chain system they use: screw-drive system, chain drive system or computer controlled system. The screw drive system has a mechanism that moves the length of a steel rod; it is a lifting mechanism that is mounted in your garage ceiling.
The chain drive system is made of a chain that moves the door along a pair of tracks; this is the most common and affordable system but also has the disadvantage of being extremely noisy. The computer drive mechanism doesn’t use any screws or chains; the system’s body is mounted above the door.
The speed and the type of power are other factors used in selecting a new garage door. A faster door means a more expensive one, but this feature reduces the waiting time on your driveway. Even though it opens quickly, a door usually closes pretty slowly for safety. The power
of the motor is important in choosing a door because it has to have enough power to raise the door; a large motor is likely to last longer. Also the quietness of the motor should be another decision factor.
Enhanced security features can be found in a newer generation door that uses random codes. A new random code is generated each time the remote control is used to open the garage door. This security code prevents you from opening another garage and vice versa. The remote control may be found in several models with a different number of buttons. A multiple button remote control is the best choice for someone who has several garages. The fixed controller is mounted on the wall either inside or outside, near the garage door and it allows the garage door to open without a remote controller. The keypad allows to close the door for a specific period of time and it provides enough time to exit the garage without running.
Safety features are present on every garage door. These features prevent the door from crushing objects or people by reversing the direction if it hits something. This safety feature is triggered by an electronic beam and it is mandated by law. A computer-controlled mechanism can detect or compensate for varying conditions, for example if the door is coming in contact with an obstruction or is closing too fast.
