What is R-Value?

Posted on AC Tips, Money Saving Tips, The Cooler Blog September 29, 2010

R-value is a term used to describe the thermal resistance of insulation. To put it in practical terms, the deeper the insulation, the higher the R-value. Minimum or recommended R-values are set by building codes as well as the Department of Energy. In South Florida, R-values of R-30 to R-60 are usually recommended to help keep conditioned air from escaping through your attic.

All Year Cooling uses blown-in fiberglass insulation from Owens Corning. As opposed to cellulose that has been known to settle over time, fiberglass better maintains its R-value over the life of the product. We even use R-value rulers to make sure that the job is done right with the appropriate amount of insulation throughout your attic.

Properly installed insulation (we lift your ductwork and use rafter vents so your attic can breathe) at the appropriate R-value can do wonders for your energy bills, especially in a warm climate like South Florida. Call All Year Cooling and we’ll answer all of your questions about R-value or insulation in general.
