Prodex Insulation?

[rose090999]

Anybody use this stuff? Prodex 10M is R22 rated and is resistant to moisture and is supposedly designed for steel buildings (aka cargo trailer ). Sounds like the perfect insulation for a CT.

I recommend foam board. It supports internal and external sheathing, unlike a spongy product.

And it's closed-cell and readily available.

It's R value seems to depend a lot on its reflective qualities. That only works when exposed, not covered up.
