OK, when you start talking about 3rd order effects of parameters, that really make me want to ask about my system and actually pay you for your advice!! Thank you for being here for the community, Dana!

Dana - if you don't mind me asking, what do you do for a living? You must have a Materials Science, or Mechanical Engineering background. I really appreciated hearing the details behind your explanations for my bathroom water vapor post. It always amazes me how much folks take for granted in a house/building design. Many right decisions must be made for the "system" to work. I'd appreciate any reading material you can recommend on the subject. I'm comfortable with Engineering math. Thanks again for your help and best wishes! Tom/ourzoo
