OAKMONT, PA (May 6, 2026) – Chelsea Building Products, an Oakmont, PA-based vinyl extruder and
building-product component manufacturer with more than 50 years in the region, celebrated the grand
opening of its new 228,000 square-foot facility in Madison, PA. A ribbon-cutting ceremony was attended by
employees, customers, elected officials and business leaders, including Peter Dewil, CEO of Chelsea
Building Products; Gary Hartman, vice president of Chelsea Building Products; and Dan DeBone, president
and CEO of the Westmoreland County Chamber of Commerce, along with ownership and management
from aluplast group.

The new facility, being called Chelsea Building Products East, represents a significant investment in
advanced manufacturing technology, regional job creation and the continued growth of the greater
Pittsburgh-area economy. Strategically located with access to major transportation corridors, the facility is
designed to enhance production efficiency and strengthen the company’s ability to serve customers across
North America.

The Madison facility will support the Company’s expanding manufacturing operations by extruding PVCbased
window and door profiles, while also housing state-of-the-art blending and lamination operations. This
blending facility will supply proprietary PVC compounds to both Chelsea Building Products East and its
sister operation in Greenville, Texas, further integrating the company’s production network.
“Chelsea Building Products is continuing to invest in the future of manufacturing across Western
Pennsylvania,” said Peter Dewil, CEO of Chelsea Building Products. “This facility reflects our long-term
commitment to innovation, operational excellence and sustainable job creation in the communities where we
operate. It strengthens our ability to serve customers while supporting economic growth in the region.”
Chelsea Building Products will employ between 100 and 150 workers within five years, creating new
opportunities in skilled manufacturing, engineering and operations.

president of Chelsea Building Products. “It enhances how we operate at every level, giving us greater
flexibility, strengthening our supply network and ensuring we continue to deliver the high level of
