## R-VALUE COMPARISON FOR ICF VS CMU

An 8" CMU ( concrete masonry unit ) wall has an R-value of 2.0, If you determine it is necessary to increase insulation, you would elect to install a 1/2" rigid insulation board that has an R-value of 3.2, bringing the total R-value of the CMU wall to only 5.2. An ICF block or EPS panel have an R-value of 10 per panel and the 6" core of concrete has an R-value of 36, The panel system alone has an R-value of 20.36. This is a 390%+ increase in R-values. This confirms to a
