EPDM is far more common in the north than in the south these days. Cheaper reflectivewhite membranes such as TPOhave largely replaced them in warmer climates due changing energy code and LEED requirements. In addition, the uncured or semi-cured EPDM roofing material used for roof flashings tend...
Some flooring underlayment also provides a vapor barrier, keeping the top floor completely dry. A moisture barrier is needed for any floor that is below ground level, and is also useful over aplywoodsubfloorabove acrawl space, which can be quite damp. If there is none, a thin plastic laye...
