What is Drywall?
Drywall is a modern building material that comes in large panels (typically 4' by 8') having a gypsum core sandwiched between two heavy paper faces. These paper faces are often made from recycled paper. One face is very smooth and is the surfacing face and the other is more of a kraft paper backing face. It replaced older and more labor intensive interior finishing processes involving plaster and lath. Drywall came into popularity after WWII as faster and less expensive methods of home building were being developed.
Drywall is now the de-facto standard of interior wall surfacing used in new home construction and existing home repair and renovation.
