WebJan 5, 2024 · A U-value is typically a low number because it is a rating of how much heat energy is lost or gained. If we look at the two values mathematically, U-value is the reciprocal of R-value; that is, U = 1/R and R = 1/U. For example, a material with an R-Value of 5 has a U-value of 0.2 (1 divided by 5). A high R-value means a low U-value but the real ... WebThere is a relationship between U-value and R-value—they are mathematical reciprocals of each other. Thus, while lower U-values indicate better insulating performance, higher R-values indicate better thermal resistance. To calculate R-value, divide 1 by the U-value figure. For example, a U-value of 0.10 equals an R-value of 10 (1 divided by 0 ...
