I wish you all could have been here to see us try to put this insulation up over the sprayed foam. It is a bit frustrating because there are places that the foam is thicker so you have to thin out the insulation. Well, we found it worked best to take some off even before trying to put it in because we would have this big poofy thing bubbling out. Mom and I were about to go nuts and after about and 1 1/2 of work we weren't far. Mom had about three full pieces up. Well, they were up then back down then up. Mom said she was about to say a bad word. =0 She opted to shake her head a good one and go back at it! =) LOL Works every time! We were done by 11PM
