I finally found a local dealer for some of the OC 703 (2") rigid fiberglass...

They have both the foil-lined and the paper-lined. I remember reading some posts quite a while ago about the advantages/disadvantages of each...can someone refresh my memory?

I am looking to build traps that will have 4" of 703 (2 layers of 2") in a wood frame with a similar design to Ethan's DIY models. I'll be trapping each corner, plus the ceiling/wall junction above the back of the console. I have some foam on the side walls now, but might replace them eventually.

Any help would be greatly appreciated.
