Thanks for the good luck wishes, Marty.
Glad to see you making some posts... you may as well become a regular participant here! We would enjoy your company.
You mention that you "had" a large layout. Do you still have it? I would enjoy seeing pics if you have any
Back to the vapor barrier. I researched the average temperature in Ontario versus Houston (all in Fahrenheit):
Houston: 50, 54, 61, 68, 75, 80, 83, 82, 78, 70, 61, 54
Ontario: 21, 22, 31, 43, 55, 64, 69, 68, 60, 48, 38, 27
Average for the year in Houston is 68 degrees.
Average for the year in Ontario is 46 degrees.
Y'all are typically running your heaters, which are probably gas powered, which creates alot of water vapor inside the house. We are typically running our air conditioners which removes water vapor from the air inside the house. So, Ontario homes have water vapor on the inside trying to go out. We have water vapor on the outside trying to come in. It is not surprising that the drastic difference in climate requires drastically different moisture control systems, and drastically different code requirements.
Thanks for the discussion, it certainly keeps me on my toes so I don't make any mistakes with this project.
