The history of drywall begins around 1915. The major component is the mineral gypsum, which is processed into sheets and then wrapped in paper. A variation of the basic drywall is greenboard, which is designed to be more moisture-resistant, and up until recently was the preferred backer for ceramic tile in bathrooms. Today, cement fiber backer board is preferred, and mandated by the local building code in many areas.

Over one-third of the material used to manufacture gypsum board is recycled from other industrial processes and the facing material on paper-faced gypsum products is 100% recycled paper. Many production facilities use only recycled material to manufacture gypsum products.
Gypsum board is everywhere. It covers the interior of more than 97% of the new homes constructed in the U.S. and Canada, and is used to finish the interior and sheath the exterior of non-residential structures throughout the world.
From a humble beginning as a plaster lath, gypsum board has evolved to include products that provide increased sound attenuation, superior impact and weather resistance, and improved mold and mildew resistance, while continuing to dis- play the natural fire-resistive quality inherent in gypsum.
