I'm starting to finish my basement this month and I want to be careful how I proceed. I've been reading through the various arguments posted here relating to vapor control and I've been visiting's website for about 6 years now and their vapor control advice makes sense. I certainly does not make sense to place a vapor barrier on the warm, moist interior side of a basement wall and trap moisture inside the wall assembly which can enter through the concrete. That much is clear. Anyone thinks this is ok only needs to read the first posting in this thread to see what can happen.

However, it also seems to make sense that I could avoid the process of gluing foam board insulation to my concrete wall (approx 35, 4x8 sheets in my case), by applying 6ml plastic vapor barrier directly to the concrete wall (a fraction of the time and cost), and build the wall assembly to the inside of the plastic with low-cost batt insulation. Further, since my region is considered "cold climate", I am considering building a 2x4 studed wall with 16" centers about 3 inches away from the concrete wall. I could then install 20" R11 batt insulation behind every second wall cavity, overlapping behind each stud. I would then place another 15", batt between the studs, alternating R11 & R20. This would have a similar effect to gluing the foam board behind the wall assembly, but would take far less time & cost to install.

Does this make sense to anyone? Has anyone ever tried this approach? I'm a "layman" when it comes to construction but if you agree with the principles as set out in, you would also agree that this approach might also work as well.

Look I will be honest I have been in the home improvement and construction business for over 9 years, I have seen many strange do it your self fixes, I cannot see the alternating batt insulation fulfilling your needs.

Ask your self a few questions, how much space am I needing, to use in my basement.

A good estimate is when you have a family get together, how many rooms on the main level do you use, Dining and Den, or Living room and kitchen.

What do you want to use the room for, play room to your self, the kids, extra bedroom, or office.

Truely, I have finished basements for millionaires and mechanics, the largest space ever needed was 600 square feet, most families need only a 300 sf room. Now take that figure and mutiply by you area contruction costs for a sunroom, and you can have a finished room that you be able to quickly enjoy look into the Owens Corning Basement Finishing sytem.

It will cost you less in the long run and perform better than anything you could make on your own.

Just as I know it - I tell it straight
