finishing Basement

I'm about to begin finishing a poured concrete basement. I will be using 2x4 framing, I'm confused on this vapor barrier process? The house is approx 3yrs old, and the foundation is dry with no visible signs of moisture. I have been told that a 6mil vapor barrier attached to the cement all around the basement, including on the floor (I will be putting a 3/4 pressboard tounge and groove with rigid insulation between 2x4 on the flat) is the way to go here. It has been recommended to me that in conjunction with the 6mil barrier I should 2x4 frame approx 5 1/2'' out from the cement and use 3 1/2'' UN-faced fiberglass insulation before installing 1/2'' sheetrock??? Is this the right way to go???
Any help would be greatly appreciated. I live in Long Island NY if this helps anyone . Thanks Again

Finishing basement

Go back to Basement Forum Home Page and click the thread called Vapor Barrier which explains how the vapor barrier is installed on basement walls. "Vapor barriers always go on the heated side of the area you are insulating."

Go to for very helpful info that will probably answer most of your questions. Walls and floor are typically sealed with a couple coats of quality masonry sealer before beginning the project. Whether or not to use a plastic vapor barrier on the basement floor will depend on the type of floor covering you select.
