Gray is providing architectural, engineering, construction management, and equipment procurement services for the ongoing project. The new space adjoins the existing property and will include a ventilated warehouse and air-conditioned office and manufacturing areas. To accommodate the large process equipment necessary for fiberglass manufacturing, Gray will construct a 33′-deep basement.


“With this new state-of-the-art facility, Owens Corning is investing in the future of Fort Smith and our business,” said Marcio Sandri, president of the composites business at Owens Corning.
