Rod,
I'm sure you receive these messages all the time, I but I can't thank you enough for your awesome book! I'm building a LEED certified green home and need your help.
Have you ever design/constructed a "Green" studio?
I'm pouring 10" concrete walls for the entire parameter/surround of the room with an airlock and want to know if you think your proposed insulation with multiple layers of 5/8" gypsum dry wall will be necessary still? Further more, have you ever used Icynene or a similar spray foam insullation and does it perform as well as the insullation/drywall scheme you wrote in your book.
Thank you so much,
Patrick
