Basement Vapor Barrier

Topic: 
Basements and Crawl Spaces
Question: 

In renovating my basement I'm wondering if I put the plastic barrier against the cement blocks before I install the framing studs, or after the framing studs are installed, or both. I've heard both situations.

Answer: 

Hold the framing away from the walls an inch or so. The vapor barrier is best installed on the inside of the insulation under the drywall.
