When buying a new garage door, one information that is being hyped by manufacturers is its R-value. But what is R-Value?
R-Value is a common term that is used to measure the ability of an insulation material to resist heat flow conductions. While knowing about this is important, how much do these R-values affect your door? And what are the things that you need to know so that you can make a better decision regarding this?
Here are the 3 things that must know regarding R-Values:
1. Doubling the R-Value does not double the insulation.
R-Value numbers don’t have one-to-one ratio with the heat flow reduction amount. For instance, switching the R-Value of 8 to 16 will only give you a heat flow reduction increase of 5%.
Don’t be deceived believing that higher R-Values can give you a substantially better insulation when compared to those lower R-Values. Note that higher R-Values will only be better but not double better.
2. Published R-Values can be deceiving.
The R-Values that were published by manufacturers are not all accurate because of the controlled conditions of its laboratory. Manufacturers test one piece of a door, usually the center, and not the entire door across the gaps where heat loss usually occurs.
3. Do not choose a door just because of its R-Value.
Having R-Value as your standard in choosing for a garage door is not correct. When you want to ensure energy efficiency, you need to consider other factors also. These factors are proper caulking and seal as well as the tightness of fit in the door’s opening. All of these factors can affect heat loss, thus, should be assessed on top of R-Value.
Always ask your garage door manufacturer about the installed R-Values and make sure that that you choose the best one. Make sure that you hire professional installation teams to ensure that the garage door will be a great heat saver.
