The Best Metal Building Insulation Options and Materials

When choosing metal building insulation, there are several thicknesses or R-Value's to choose from ranging from 2 5/8" R-8 to 9.5" R-30. Up to 6" R-19 can be used in a single layer appliction. Multiple thicknesses or layers can be combined in a double layer system to achieve high R-values. This is dependent on the depth of the purlins / girts.
