Curious on stories when IAQ testing for LEED or WELL didn't come back with "all clear, everything's good" results we all hope for. 

I have a project right now where we are tracking down suspicious sources and look forward to telling the full story when it's done being written.

Board insulation has good thermal performance ranging from about R-4 to R-8 and is used as an integral part of a building envelope’s continuous insulation system.
