Garage doors, even if they are made of the thinnest grade of steel, still can be excessively troublesome and heavy to open for the typical individual. Add insulation to the door and it becomes much heavier. Compound that weight with an arm filled with children or groceries and a really troublesome experience will unfold.
Garage doors can be found in all widths and heights. The weight can vary considerably also, relying on the kind of material and building of a garage door. Heavier garage doors will need a more powerful garage door opener than the standard uninsulated aluminum garage door. Which type of motor will be strong enough to raise a specific garage door is a concern that any expert installer or producer will be able to respond to.
Every garage door opener is not created similarly. There are predominantly 3 different kinds of drives readily available for garage door openers, chain drive, screw drive, and belt drive. Each of these openers has advantages that the others do not have. A 4th kind of drive called a torsion drive is also available, however can be finicky if not installed exactly, so is finest left to an expert installer.
The most fundamental kind of electrical garage door opener is the tried and real chain drive. Just like a bicycle chain, this specific drive needs periodic lubricating oil and will require change as the equipments and chain ages. Chain driven garage door openers produce the most noise from all types on the market and are readily available with different sized motors for much heavier or larger doors.
Screw drive door openers are thought about to be the most resilient or maintenance free type of opener due to the style of the drive. While the installation procedure is nearly similar to chain drive systems, the carriage of a screw drive opener “trips” along a spiraled screw type rod. This system has the least moving parts of any of the main 3 garage door openers and does not produce as much noise as the chain driven systems. The expense of screw drive openers are roughly $30 to $50 more costly than that of their chain drive equivalents. Perhaps the most valued advantage of screw drive systems is that many open at twice the speed of other drives reducing the wait time to get in the garage.
The quietest design of garage door opener is a belt driven opener. These systems use a steel enhanced rubber belt to raise the door. As a result, there is no metal on metal contact in between the lifting mechanisim and drive equipment. While there will be some noise from the door rollers inside the tracks, belt drive openers are missing out on the bulk of the sound related to basic door openers due to drive design and motor. Belt drive openers are the most expensive of the three types, but produce almost no obvious sound. If a garage is located beside a bedroom, it is uncertain that the occupant would hear the garage door opening at all. In fact, the average house owner will be acutely conscious, initially, of the belt drive motor because of the lack of excess noise.
While the typical handyman may have the skill to set up a garage door opener, it can be an extremely aggravating procedure due to the support that may be needed to the header of the garage opening, the ceiling of the garage itself, and any modifications which might be essential to the torsion springs.
Torsion springs should NOT be adjusted by the average house owner or handyman. Proper specialized tools are required to change torsion springs safely. A knowledgeable and educated specialist must be hired to adjust the torsion springs securely and correctly. Major injury or worse can take place if the torsion springs are used or not changed properly.
