What is the proper way to install a vapor retarder?

Tim writes from Hainesport, New Jersey: "I'm trying to determine the proper way to install a vapor barrier. I've just recently begun refinishing my basement; even though I've never experienced any water or moisture problems I chose to seal the walls and floor with DryLok just as a precaution. Now I plan to install 2x furring strips along the walls and put up 1 1/2" extruded foam insulation, tape all seams and caulk all joints.

Then I will frame the walls with 2 x 4's and insulate with fiberglass batts. My confusion comes with the installation of the vapor barrier. Some things I have read state to install the vapor barrier closest to the warmest side of the room directly under the drywall.

Others say to install the plastic along the concrete walls. Which is correct? Wouldn't the installation of the DryLok and rigid foam essentially be a vapor barrier?

And, should I use fiberglass insulation that has a paper facing, or not, in conjunction with a plastic vapor barrier? Sorry this ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
