Gypsum drywall is an effective building material because gypsum is very fire-resistant. The gypsum molecule contains within it two water molecules and one calcium sulfate. Because gypsum plaster dries so much faster than lime plaster, it is much less likely to become damaged in the process of setting up.Gypsum drywall is an effective building material because gypsum is very fire-resistant.
