I have been searching on here trying to find out if anyone has ever thought of using Tar-paper under the Aluminum? I have been in Home construction for 30 years and we use it behind siding and brick work and under all shingle work. Will this work or is there a downside? It is waterproof and one roll will do a tear. I am getting ready to cut out the walls for my Kenskill and I was thinking of doing it to mine.
Thanks
