I am installing a floating laminate wood floor on an 11th floor concrete building. So therefore my subfloor is concrete. Most place say to put a 6mil poly vapor barrier on top of the concrete. I can understand this if you are in a house and you have water vapor seepage from the foundation and the earth, but I am on the 11th flor of a condo. Do I still need that vapor barrier???
