Cornerstone Building Brands Expands Rocky Mount, Virginia, Production Operations

12/10/2025
Exterior building products manufacturer Cornerstone Building Brands plans to expand its operations in Rocky Mount, Virginia. The $4.9 million project is expected to create 50 jobs.

The investment will enhance production at the company’s existing Ply Gem® brand windows and doors facility.

To support the project Governor Youngkin approved a $100,000 grant from the Commonwealth’s Opportunity Fund. Cornerstone Building Brands’ job creation will be supported through the Virginia Jobs Investment Program, which provides consultative services and funding to companies creating new jobs in order to support employee recruitment and training activities. As a business incentive supporting economic development, VJIP reduces the human resource costs of new and expanding companies. VJIP is state funded, demonstrating Virginia’s commitment to enhancing job opportunities for citizens.

“Cornerstone Building Brands is proud to continue advancing American manufacturing by expanding our operations in Rocky Mount where we have a terrific team,” said Cornerstone Building Brands Chief Executive Officer Gunner Smith. “This investment increases our capacity and strengthens our ability to meet future demand for our Ply Gem® windows and doors while creating new career opportunities for skilled manufacturing workers in Franklin County. We appreciate the continued partnership of the Commonwealth of Virginia and local leaders as we build on our legacy of delivering high-quality products that best serve our customers and communities.”

“Cornerstone Building Brands’ decision to expand its Rocky Mount production facility is a strong testament to Virginia’s skilled manufacturing workforce and world-class business climate,” noted Secretary of Commerce and Trade Juan Pablo Segura. “This investment will bring valuable new jobs to Franklin County while advancing the Commonwealth’s support of the vital construction industry. We look forward to continuing our partnership with Cornerstone Building Brands as it grows its footprint in Virginia.”

The Virginia Economic Development Partnership (VEDP) worked with Franklin County to secure the project.

"Cornerstone Building Brands’ expansion builds on the proud manufacturing legacy of its Rocky Mount facility, which has been a cornerstone of Franklin County’s economy since 1939,” added Roanoke Regional Partnership President and CEO John Hull. “The Roanoke region is home to a strong cluster of building products companies — from windows and glass to cement and materials — that continue to innovate, invest, and create opportunity for our community.”

Cornerstone Building Brands, formed through the merger of NCI Building Systems and Ply Gem Building Products, serves both new construction and repair and remodel markets with offerings including vinyl windows and doors, vinyl siding, stone veneer, metal roofing, metal wall systems, and metal accessories. In addition to Ply Gem, the company’s brand portfolio includes Simonton® Windows & Doors, Mastic by Ply Gem and Mueller.
