Construction is underway for a new manufacturing facility that officials said could bring as many as 150 new jobs to Westmoreland County.

Officials this week held a groundbreaking for a 228,000 square-foot building at Commerce Crossing, the county’s newest industrial park, in Sewickley Township.

Chelsea Building Products paid $1.8 million to purchased the 30-acre lot in late 2023.

It’s expected to be the Oakmont-based company’s second manufacturing facility. It will produce extruded PVC-based windows and doors, and compound materials used on site and at the company’s plant in Greenville, Texas.

The facility will feature insulated precast construction. It will have 100-by-50-foot bays in the production areas, 10 fully equipped dock positions and a 10,000-amp electrical service.

Its design also allows for a future expansion of about 170,000 square feet, according the county.

“Chelsea Building Products is excited to continue with its aggressive expansion plans by opening a second facility in Pennsylvania,” said Peter Dewil, president & CEO of Chelsea Building Products. “This facility will give us the opportunity to increase our capacity to meet the ever-growing demand for our products.

“It will also improve efficiencies by bringing manufacturing and warehousing under a single roof. We are also thrilled to be bringing more job opportunities to the Westmoreland County community.”

Officials previously said the new plant could employ up to 150 workers when completed.

Commerce Crossing is the newest of Westmoreland County’s 19 industrial parks. It has three occupants at the 206-acre site, with two lots available for purchase or lease.

“We’re very excited to welcome Chelsea Building Products to the WCIDC park system,” said Jason Rigone, WCIDC executive director. “This investment to build a large manufacturing facility is a clear affirmation of our vision for Commerce Crossing, and we’re confident that the park’s last two available pad sites — both ranked as ‘Tier I’ by the state — will host groundbreaking ceremonies of their own in the near future.”

Brian Estadt, WCIDC’s marketing coordinator, said 165 industrial properties were reviewed by the state and just 15 received the highest rating of “Tier I” status.

Westmoreland County is home to four of those top rated sites, two at Commerce Crossing, and one each at the Westmoreland Distribution Park North and the I-70 Industrial Park in East Huntingdon, Estadt said.
