CertainTeed Corporation recently marked the grand opening of its new, state-of-the-art mechanical insulation manufacturing plant in Sherman, TX, with a visit from Texas Governor Rick Perry, dignitaries from Grayson County, and members of the media. The opening of the 518,000-sq-ft plant, located 50 miles north of Dallas, brings new life to a former auto glass manufacturing plant which had stood idle for four years. The plant will employ up to 50 people when fully operational. CertainTeed has already committed to approximately a $15 million capital investment to make the plant the first and finest U.S. plant designed especially for the production of textile fiber glass duct liner used to insulate heating and air conditioning duct systems, according to company officials. The new product being produced in the Sherman plant is called ToughGard®2, a fiber glass textile duct liner for heating and air conditioning systems. For more information visit www.certainteed.com.
