I ran into an ex QA team member and his friend at Lowe’s this week. Had a nice conversation about alt energy and gasification, They alerted me to the stone wool insulation shown here. It says it’s good to 2150 degrees F. A little pricey and a lot of insulation, but it sure looks like a gasifier candidate. I’m going to spring for a package and I’ll show you what it looks like unwrapped. More tech info at roxul.com
