WebAverage R-Value is the measure half-way between the minimum and maximum r-value in the tapered system. Average R-Value is the quantity that should be used to calculate real heat … WebHeat loss through tapered roof insulation is generally computed using an R-value based on the average thickness of the tapered section. However, this misrepresents the actual performance of the tapered insulation, which is always less efficient than an equal volume of untapered insulation.
