Using used (recycled) rigid insulation
hey guys, thank you in advance to any that answer or help with my questions.
i recently bought some used 4″ Dow Roofmate rigid insulation from a roofing contractor. i plan on using it on my crawl space foundation walls. one side of the insulation is a bit distressed and by distressed i mean it has cuts, slices and dents. will this affect the performance of the insulation? should i face the distressed side against the wall or the good side against the wall? would it help at all to paint the distressed side with a latex paint? any thoughts would be appreciated. thank you
