Did my contractor install open cell when he said he’d do closed cell?
So we finally pulled the trigger and hired a company to do two inches of closed cell foam at attic decking and one inch along eaves. It smells slightly like mildew 24 hours later. It seems softer than I was expecting, especially where it looks ‘bubbly’ … I asked for Lapolla Foam-Lok 2000-4g. Pictures below. I can even poke a finger in. (Last picture shows that) Did I actually get closed cell foam?? Also, what should I do about the several spots where the foam is pulling away from the rafters? Not counting the bubbly edges, it seems I have 3 inches left in the 2 by 6 rafter bays. Will the R-23 mineral wool batts still work compressed in that space? If not, should I get R-15 instead? (Is that enough to be safe as thermal protection in a space used for storage)? We will be putting half-inch drywall on the vertical walls/eaves, where the foam nearly fills all the space) Should I cut away the bubbly edges? Should I do any caulking between chimney and rockwool? They had said they would but then didn’t bring any.
Thanks for all your help.
