Closed-cell foam bubbles are filled with gas. When it cures, it becomes rigid and can actually add strength to the structure. It has a high R-value rating and reduces sound by up to 50 decibels. Closed-cell foam insulation also becomes a class II vapor barrier when applied at depth of 1.5” or greater
Closed-cell foam: Up to R-7 per inch , 1.7-2.3 lbs/cubic ft
