Wallboard manufacturing is the primary use of gypsum in the U.S.

Gypsum is most commonly used in the production of wallboard (drywall) for construction. The U.S. is one of the largest producers and consumers of gypsum, which is essential for building materials used in residential, commercial, and industrial construction. The mineral is prized for its fire-resistant properties and ease of use in creating smooth, durable surfaces. Gypsum is also used in cement production and as a soil conditioner in agriculture, but its most significant application remains in the production of drywall and plaster products for the construction industry.
