PPG is back in production at its Fresno, Calif., location, and it’s coming back with a bang.

The company had announced a “force majeure” two weeks ago on its architectural, residential and specialty glass products for customers located in the western U.S. and western Canada. PPG has now restored normal operations at the facility and announced plans to invest $20 million in upgrades.

“We are pleased today to resume production at the Fresno facility and look forward to once again supplying our flat glass to meet customer demand in the western U.S. and western Canada,” says Richard Beuke, PPG vice president of flat glass. “As we look ahead, our planned investments at the Fresno facility will help to further enhance our production capabilities to meet our customers’ needs in the future.”

The upgrades, which will begin in January 2016, include the rebuilding of its glass tank and other manufacturing equipment enhancements at the plant.

On September 11, PPG announced the force majeure was due to “unanticipated mechanical production issues” at the location. The company had been unable to produce glass at the facility since August 30 but is now back in production.

The Fresno plant, which has been in operation since 1967, produces flat and tempered glass for the residential and commercial construction markets. It employs 140 people and is one of the company’s key manufacturing facilities, along with its Carlisle, Pa., and Wichita Falls, Texas, locations. The company’s Mount Zion, Ill., facility was sold last year.

A representative of PPG was unable to provide additional information as of press time.
