Abstract
A unit of measurement of resistance to heat flow in hr. ft2 ° F/BTU.in. (imperial) R-Value is Measure of resistance to heat flow. Insulation materials have tiny pockets of trapped air. These pockets resist the transfer of heat through material. The ability of insulation to slow the transfer of heat is measured in R-values. The higher the R-value, the better the insulation material’s ability to resist the flow of heat through it.
