Help! My husband and I were watching several months ago when an episode aired realted to insullation that was blown by a gun in a newly contructed home. I don't remember the name of this insullation, but it was not fiberglass. It expanded into all the cracks as it was blown in. My husband is interested in finding out what this is because no one does that in our area. He thought it would be a profitable business to get into.
