| Q: What makes Eterpan backing board different from moisture resistant wallboard or gypsum backing board?
back

Moisture resistant wallboard (greenboard) is not intended for use in wet areas and is no longer approved by the International Residential Code for such applications. Gypsum is known to disintegrate over time with continuous moisture exposure and the paper facing on greenboard can serve as a food source for mold. Unlike gypsum wallboard, Eterpan backing board's cement formulation stands tough over time and under water.
