Hope I'm not OT here but I finished my furnace and have several feet out of a roll of Inswool - HTZ left. Stuff wasn't cheap so I was thinking of making some 1' x 2' x 1" thick sections and pawning the rest on eBay for $12 a pop. It's actually pretty cool for furnace lining. If interested let me know and I'll actually get off my butt, take a picture and post the stuff. Otherwise it'll be aging in my basement.
Here's the spec sheet:
