What is R-value, when it comes to garage doors?

The R-value tells you how well your garage doors are insulated and how good a job they’ll do of keeping in air-conditioned or heated air. The higher the R-value, the better the insulation, with the best-insulating garage doors at around the 6.5 mark. The garage tends to be a multi-purpose area doubling as a workshop, man cave, or home office, all of which mean human beings will be using the space for long periods. To do so comfortably in most American climates, you’ll need efficient HVAC at least part of the year. Even when your particular garage is just a place to park the car, if it’s attached to your house, it will affect the temperature inside your home.

When doing research on different types of garage doors, you may have come across an “R-Value” measurement associated with garage door insulation. What is R-Value? 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 R-value is a good thermal indicator of the insulation properties of the door panels. However, do not overlook the seams and seal around the door. If you take into account the energy efficiency of ALL the door components (door panels, seams between panels, side and top seals, bottom seal) then a U-factor is a better measure.
