Closed cell foams that contain blowing agents, like HFC, HCFC or HFA, can suffer from reduced R-values as a result of blowing agent loss as air leakage takes place into the cell structure. The R-value of Icynene open-cell spray foams is generated by millions of tiny inter-connected, air-filled cells and the R-value does not decline as it ages.
