May 25, 2021Reference Table for U Values U Value is the coefficient of transmission, i.e., the transmission of heat through the materials, which compose the building's envelope, or outer shell. U Value has an inverse relationship to R Value. For example, a building with material with an R Value of R-11 converts to an U Value of 0.09 ( 1/R or 1/11 = 0.09).
