Gypsum board is often called drywall, wallboard, or plasterboard and differs from products such as plywood, hardboard, and fiberboard because of its noncombustible core.
What Is Gypsum and Gypsum Board?
Gypsum board is the generic name for a family of panel-type products consisting of a noncombustible core -- made primarily of gypsum -- with a paper surface on the face, back, and long edges.
Many gypsum manufacturers, including Lafarge, also rely increasingly on "synthetic" gypsum as an effective alternative to natural gypsum ore.
Synthetic gypsum, also know as calcium sulfate, is a by-product of the desulfurization process coal-fired plants use to reduce air pollution. Considered a waste product, calcium sulfate is typically hauled away and disposed of in landfills. Because it is chemically equivalent to natural rock gypsum, synthetic gypsum can be used as an alternative resource when available.

Each of our facilities incorporates the latest manufacturing technology, including the ability to recycle drywall to help protect the environment and preserve our natural resources.
