PPG to Invest $70 Million in Huntsville Aerospace Transparencies Expansion

PPG plans a $70 million expansion of its Huntsville, Ala., aerospace transparencies site, including a new 112,000-square-foot support facility.

PPG Industries, Inc. (Pittsburgh, Pa.) has announced a $70 million investment to expand its aerospace transparencies site in Huntsville, Ala. The company said the investment forms part of a series of multi-year projects intended to increase production capacity and support continued growth of its aerospace transparencies business.

According to PPG, the expansion includes the lease and build-out of a new 112,000-square-foot facility that will house production support functions. Relocating those functions is meant to free additional manufacturing space at PPG's existing aerospace transparencies facility. The company said the projects are designed to strengthen its ability to meet customer demand for aircraft cockpit windows and passenger windows while positioning the site for future growth.

Company cites demand across aviation markets

"Demand for aerospace transparencies continues to grow across commercial, military and general aviation markets," said Francois Buehlmann, PPG general manager, global transparencies, Aerospace. He said the expansion is expected to increase operational efficiency, provide room for future equipment investments and reinforce PPG's long-term commitment to serving customers and investing in Huntsville.

Buehlmann also said Huntsville is recognized globally for innovation and leadership in aerospace, adding that PPG is proud to continue investing in the community and looks forward to growing alongside the region's aerospace network.

PPG said it has operated its aerospace transparencies manufacturing facility in Huntsville for more than 55 years. The company's aerospace business supplies coatings, sealants, transparencies, engineered materials and related services to commercial, regional, general aviation and military customers worldwide.
