I am investigation the use of steel sips. There is one thing I am concerned with.
I know the metal building guys were all over spray foam insulation direct to the metal until folks started noticing that it would lose its adhesion after a while. So they quit applying direct.
So, how can a steel sip be any different? What about the metal sweating? Is this a concern?
Thanks,
Mike

Mike;

Could be when the metal building guys sprayed the metal was already wet?

EPS steel Sips are not a sprayed application, the EPS foam core is laminated with waterproof glue, I have not ever seen any interior condensing.
Think about all the 100's of thousands of square feet of refrigeration panels being used commercially.

Same technology!
