1. If the roof and ceiling assembly of a structure has a factor of thermal conductance (U-factor) of 0.04, what should be the R-value of the insulation used in this same assembly? A. 2.5 B. 10 c. 25 D. 40 1. C. The answer is 25. The U-factor is the thermal conductance of one square foot of an entire assembly. The reciprocal of U is R, which is the thermal resistance of the same square foot of construction. A U-factor of 0.04, therefore, corresponds to an R-value of 1/0.04 = 25 (choice C). ...
