MALVERN, Pa. — Saint-Gobain, through its building products subsidiary CertainTeed, announced the company will invest more than $400 million to expand its production capacity at four key manufacturing locations in the United States to better serve its customers in a high growth environment.

Combined together, the four capacity expansions represent the company’s largest organic growth investment in several years as Saint-Gobain executes on its newly announced global Grow and Impact strategy, which includes maximizing its impact in key, fast-growing markets, while striving to minimize the company’s environmental footprint. The combined investments will reduce waste by more than 50% and reduce carbon dioxide emissions by more than 20% compared to existing manufacturing technology.

“This is an investment in our company’s future, and also in our future ability to ensure security of supply for our customers,” said Mark Rayfield, CEO of Saint-Gobain North America and CertainTeed. “We will continue to look for opportunities to strategically grow and expand our business, all while striving to become the world’s leader in light and sustainable construction.”
