Residential Garage Door Opener Options
Automated garage door installation is a popular project for do-it-yourself people because of the ability to customize and control such variables as noise and speed. In general, you have three types of drives to choose from, each with unique pros and cons. None are the clear best option, meaning the type of garage door opener you choose comes down largely to personal preference. Here are a few advantages to each of the three types of automated garage door opener drives: screw, belt and chain drive.
Screw Drive Garage Door Openers
What it is: Screw drive garage door openers are different mechanically than the other two options, as they require a trolley to ride on a threaded-steel rod, which rotates with a motor to move the door. It does not require the same type of pushing and pulling force of traditional belt and chain driven garage door openers.
The advantages: Screw drive openers are simple, and for that reason, preferable for people who want fewer moving parts to maintain. Screw drive units are somewhat sensitive to temperature and are not considered optimal in regions that see drastic shifts in temperature as seasons change. In most cases, they are noisier than belt drive units. Cost-wise, screw drive units tend to be more expensive than belt drive and chain drive openers.
Chain Drive Garage Door Openers
What it is: Chain drive units are classic garage door openers and are among the oldest and most common styles, running the door along a track. These units rely on a bicycle-like chain to push the trolley connected to the J-arm, which is attached the garage door itself.
The advantages: One caveat (or advantage, depending on how you look at it) is noise. Because of the design, chain drive units tend to cause a slight vibrations and metal-to-metal noise. For that reason, these units are more popular for detached garages than garages situated beneath a bedroom, for example. Some people prefer a garage door that opens with a bit of racket so they can be warned if someone is about to enter. Over time, chain drive units have become much quieter with newer technologies, such as softer start-and-stop features and DC motors. Chain drives are considered to be the most economical option.
Belt Drive Garage Door Openers
What it is: For many people, belt drives are considered to be the most luxurious option because of their sleekness and relative low level of noise. Belt drive openers use the same mechanisms as chain drive openers, with the exception that instead of a chain, they use a belt — largely eliminating the vibrations and noises associated with chain drive openers. The belts are typically made from fiberglass, steel-reinforced rubber or polyurethane.
The advantages: Belt drive garage openers are the quietest types of openers (almost silent by comparison with chain drive units), although they tend to cost just a bit more than the chain option.
