I think I am a little confused. After researching all the forums, I was under the impression that the "Fabrication Billet" or "Pipe Billet" is the Extruded foam that is the correct density and cell size and is listed by Dow and ITW as XPS Pipe Fabrication billet now. And that the "Flotation Billet" is Expanded foam, weaker, lower density, and wrong cell size. Am I misinformed, confused, or neither?
