Ok i have read many posts here and the one thing everyone is missing is the 6 mill poly. You can have all the inslulation in the world but without the break it does you no good. Spraying foam on walls or ceilings you have to have an airspace at least 1" to allow for wood to breathe or else will dry rot!
