Radiant Barrier Insulation

My shop walls are all done with this. I love the stuff! No staples, waterproof, will not mold, fireproof (and I mean will not burn).
what did you cover it with? or just left it as is?
I'm thinking a plywood of sorts but do not want anything that is going to off-gas or be toxic in the air...which I guess is the same thing in different words.
