I am currently on a job where roof is being replaced > it is a large commercial shopping center. They are using a Carlisle rubber roof sytem and the dumster is full of foam board scrap,some pretty large. any reservations about using this stuff to insulate under a floor of a cabin?....Larry
No contact with wet earth. Cabin is going up on reclaimed telephone poles so I have some storage area underneath. Good idea on looking up specs. I fiquire I can use scrap over 15" and stuff them in between the floor joists ...larry
