I would like to insulate my attic floor with tiger foam since it has a higher R factor than cellulose. There are large boards that cover the floor. Can anyone tell me how to do it or any websites that would be helpful in doing this. I hae questions about handling any electrical wiring and lighting fixtures with it. I am hoping to obtain the highest R value but I still have some concerns using foam re infstation, mold, what if it gets wet from a leak in the roof etc and if there are any other issues I need to think about? There is also "zero foam" I am considering. Any help gratefully appreciated.
