The Differences Between R-values and U-values

R-Values… U-Values… What’s the Difference?

Homes and businesses around the nation have become more efficient in recent years… Credit reduced energy consumption along with improved structural insulation which protects against indoor and outdoor temperature variations.

The latter is made quantifiable thanks to R-values and U-values. R-values refer to construction components that are made up of only one material, such as cellulose in wall cavities. U-values are more of an engineering term and describe thermal performance. It’s traditionally applied to things such as window systems (which are comprised of different materials with different R-values).The higher the R-value, the better the insulation. Conversely, U-values reflect how much heat energy is lost or gained… The more energy efficient the system in question is, the lower the number.

Therefore, when seeking high R-value skylights, it is important to remember that R-values represent resistance to heat transfer whereas U-values represent the transfer of energy through conduction and radiation.
