Oh, also, don't bother using the foam as a glue. sure you can do it but you ruin the R value of all the foam you just sprayed turning it into polyurethane glue. Just jam your board on a nail and foam around it. A good tip on this is to try to cut the blocks as close to the size of the bays as possible. At first I did it leaving more than an inch around and ended up spending more money on 2 part foam than I wanted to.
