Case Studies

We opened our first window profile extrusion operation in 1975 in a small warehouse east of Pittsburgh, Pennsylvania. Back then we were a little-known operation called the Poly-Tex Company but we quickly drew attention when we introduced profiles for the first all-vinyl, tilt double-hung replacement window system into the U.S. market.

Chelsea Building Products ushered in a new and exciting era of design, engineering, and manufacturing for extruded polymer-based profiles used in windows, doors, siding, shutters, mouldings, and more. Today, our production and distribution facility located in Oakmont, Pennsylvania, operates 24 hours a day, seven days a week, producing millions of feet of lineal extrusions per year. In addition to Oakmont, Chelsea’s new Greenville, Texas location provides manufacturing and distribution services to the southern and western United States.
