    Wood needs to do what now?

      they're wrapping surface dry wood in poly foam, the wood is going to rot.
      No, it's not rocket science, it's plumbing and unlike rocket science it requires a license.

        I guess it's a good thing we get the building envelope guy from an engineering firm to put in writing otherwise before we spray those types of jobs then.

        "Dry Rot" is a terrible term, it's actually a fungus that eats the wood, and requires an elevated moisture content to thrive.
