Calculation r value of tapered insulation
WebR-value, commonly used when describing walls, roofs, and similar housing components, measures how well building insulation can prevent the flow of heat into and out of the home. A higher R-value equates to greater insulation performance, and thus higher savings on heating and cooling. WebR-value on tapered insulation systems. The R-values in the table are the minimum required. However, in roofs that include tapered insulation there is an exception that allows the tapered insulation to vary 1 inch from the minimum required. On a roof with a typical 1/4” per foot taper this results :
