What is the R-value (insulation value) of GreenBeans product?
GreenBean has a few different foam products of different densities that we use on different project types. We do not believe that there is only one product solution for every project. Although foam has the highest R-value per inch of any insulation, R-value (because of the way they test this value) is NOT a good measure of an insulation product’s true performance. Our main open-cell foam product has an R-Value of 3.9 per inch (other companies are only 3.5) & our main closed cell product has an R-value of 6.8 per inch. Our cellulose product has an R-value of 3.7 per inch. Spray foam is the only insulation product that offers a true R-value because it is the only product that creates an air seal. Don’t get caught up in the Myth of R-values. R-value means nothing without a true thermal air seal. Only spray-foam achieves this. Insulation can be 10 feet thick with an R-Value of 500 but if there are gaps around it, it is doing no good.
