Filling and emptying the tank results in expansion and contraction that can cause the foam to separate from the tank.

"Filling and emptying the tank results in expansion and contraction that can cause the foam to separate from the tank."

I wish I could go through their entire process for the foam, from manufacture content and process to installation design and application.

If a single foam panel will withstand the conditions necessary to work, I think I could fix the process and design so they all would.
