Hi everyone,
I have access to a large sun of ProTec ESP roof insulation. It has been taken off of a large commercial building. I was wondering if I would be suitable to use as frost wing insulation and possibly for under slab insulation also.
I will attach a picture for reference. It’s 2x4x 4” R-20.
They also have a pile of fibreglass insulation. Which I am thinking of using for our attic..
thoughts?
