Drywall and related wall covering sheets evolved about 100 years ago as an alternative to interior plastering.

Basically, drywall is made from gypsum plaster pressed between two thick sheets of paper, then kiln-dried. Some panels use fiberglass instead of paper or alter materials to increase moisture resistance, fire retardation, and sound blockage. Ring's End carries many different kinds of these wall sheet covering products, as well as a full array of drywalling tools
