Roofing and waterproofing manufacturer GAF has committed to build the company’s fifth polyisocyanurate (polyiso) insulation manufacturing plant in Peru, Ill. The manufacturer has signed an agreement to purchase more than 100 acres for the future home of a 450,000 square foot plant that will manufacture GAF’s EnergyGuard line of products.

Construction is expected to break ground in the third quarter of 2022 with production beginning in 2024. GAF said Peru, Ill., is an ideal location because of its access to I-80 East/West, I-39 North/South, and railways, allowing for service to all Midwest customers.

“GAF’s growth is fueled by a deep commitment to serving our customers with innovative products and outstanding service. This investment in Peru is a clear demonstration of this commitment,” Jim Schnepper, CEO of GAF, said in a news release. “Peru’s proximity to our customer base, transportation infrastructure, and access to outstanding manufacturing and engineering talent make it an ideal location for us to continue our growth.”

Polyiso is a high-performance insulation solution commonly used as continuous insulation for roofs and walls in sustainable or green building applications, according to GAF.

“Expanding manufacturing capacity is critical to continue delivering best-in-class service for our customers,” said John Altmeye, executive chairman of GAF commercial roofing. “Peru is an ideal location for us to expand polyiso production and continue innovating to meet our customer’s current and future needs.”

The Peru, Ill., plant will join GAF’s existing polyiso operations in Cedar City, Utah; Gainesville, Texas; Statesboro, Ga.; and New Columbia, Pa.
