RH in Concrete for Wood Floor with Vapor Membrane

[simmonsviolet]

Hey,
When preparing to install solid hardwood flooring, be sure that you do not install over an area with radiant heat. 15 lbs. asphalt felt must be laid to install, and a moisture barrier of 6 mil polyethylene film may also be necessary. This protects against moisture rising up from below and also helps prevent squeaking. Install the vapor barrier parallel to the direction of the flooring.
