The R-value of insulated metal panels (IMPs) varies depending on the thickness of the foam core and the type of foam used. The R-value of an IMP can range from R-16 to R-32 or more, depending on the specific product and application. The higher the R-value, the better the thermal insulation performance of the panel. The R-value of CENTRIA’s insulated metal panels achieve a staggering per inch R-value as high as 8 and U-factor as low as 0.045. With these robust insulating values, IMPs are effective with meeting energy codes across all climate zones.
