farmboy99 - 4/14/2014 21:36 I alway wonder to myself when it is mentioned on Ag Talk that a person should put a building wrap on underneath the metal then foam on the inside. People are so worried about removing that piece of metal if it gets damaged. Claiming that the foam will stick to the metal and while I agree it would stick very well why not then just put the new piece of metal over top of the damaged one. Seems simple to me. Also I have two machine sheds on the yard, built in the 70's and I do not believe any sheets have been replaced. The building may not look perfect but they are what they are. I think the bonding of the foam to the sheet metal provides a lot of structural strenght to the building that would not be the case if the wrap was used. Just my thoughts, Jim J
Jim, you are 100% correct. I'm an ex spray foam contractor
Have you ever had foam distort the metal sheets ? (getting behind and between the purlins and openings in the metal/wood, pushing the metal out, when the foam expands ?)
Just wondering, there are cases of that happening - one agtalk member has that issue. Not disagreeing . . . . .
Otherwise, I agree, the more you can "glue" everything together, the better.
Spray foam insulation for pole building?
