Well, you didn't get much help here, did you? I always used to use FomeCor (mainly because my uncle worked in the plant where it was made). He was so tickled when he came to visit just after I opened the shop, and he saw FC there! It was developed, I believe, for insulation in trailers. But I digress... If you can distribute at a good price, I say go for it. Framers seem most concerned about price on regular foam core boards. Bainbridge has that zeolite technology going for it, when it gets to the more archival versions. My main gripe is that I have noticed that foam cores aren't nearly as non-crushable as they used to be, but perhaps that is one of those "In my day, why, you could never put a thumb print in foam core by simple handling. Yes, they really knew how to build it back then." kind of statement. Was that any kind of help at all?
