United States Gypsum is making an additional capacity reduction of approximately one billion square feet from its wallboard manufacturing network and closing two other plants, according to a Securities and Exchange Commission report filed on Nov. 17. The company cites these changes as steps to adjust operations, programs and staffing to adapt to current construction and financial market conditions. Wallboard manufacturing lines at Plaster City, Calif., Jacksonville, Fla., Baltimore, and Stony Point, N.Y. plants, the cement board manufacturing line at its Santa Fe Springs, Calif. plant and its Delavan, Wis. substrate plant will be closed, either permanently or temporarily. The company expects to complete the closures by the end of the current fiscal quarter.

In addition, its subsidiary, L&W Supply Corp., has determined that it will close 31 centers by the end of the current fiscal quarter.
