Should have never dropped the coroplast

[CPoh]

I was going to use rock wool.
I was loading it on my cart at Home Depot and realized how heavy it was.
I put it back and bought the Polyisocronate boards instead.
Light as a feather. I had to put weights on it to keep it from blowing away in a breeze

True, I had an opportunity to get 2” rock wool for free, so that worked!
