FAQ

 

Q. What is the difference between a chain drive, belt drive, screw drive and direct drive?

A. Garage door openers have different systems that open a garage door. A chain drive uses a chain as the mechanism to help open/close a door; a belt drives a belt mechanism; a screw drives a corkscrew rod; and a direct drive attached directly to the torsion bar to help open/close a garage door. Belt drive openers tend to be quieter than chain drive openers. Screw drive openers are known to require less adjustment over time. Direct drives take up less space in your garage.

 

Q. Why should I choose an insulated door?

A. A garage door opening is very large. Insulated doors will help to reduce the transfer of heat or cold air into your garage. This is important for a number of reasons:

1) If your garage is attached to your home, air in the garage can travel through the doorway to your living area. An insulated garage door will reduce the transfer of air from the outside to the inside.

2) If you use your garage as a workshop, your comfort will be a top priority. An insulated garage door will help keep the temperature in the garage within a narrower temperature range as compared to the extreme range of the outside temperature.

3) If your garage is below another room in your home, air can travel through the ceiling of the garage into the floor of the room above. An insulated door will keep temperatures in the garage fairly stable to reduce the temperature fluctuation in the room above.

4) An insulated garage door is generally quieter and has a more attractive interior than a non-insulated door.

 

Q. Difference in R-Values?

A. R-value is a measure of thermal resistance used in the building and construction industry. Specifically, R-value is thermal resistance to heat flow.

The higher the R-value number, the better the insulating properties of the material. However, an R-16 value is not twice as good as an R-8 Value. R-16 does not offer twice as much thermal resistance or twice the energy savings of an R-8 value. A value of R-16 offers a 5% reduction in heat flow and a 5% improvement energy efficiency than a value of R-8, not 50%.

No matter the R-Value, an insulated garage door will reduce the amount of heat flow and improve energy efficiency of a home.

 

Q. Is 25-gauge steel thicker than 24-gauge steel?

A. No. The lower the gauge number, the thicker (and stronger) the steel.

 

Q. What is MyQ?

A. MyQ technology enables you to manage, monitor and control everything from your garage door opener to lights and beyond—anytime, and from anywhere.
