U value - coefficient of heat transmission, is a measure of the rate of non-solar heat loss or gain through a material. U-values gauge how well a material allows heat to pass through. The lower the U-value, the greater a product’s resistance to heat flow and the better its insulating value. The inverse of the U-value is the R-value.
