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.

Over the years we have developed hundreds of innovative products by listening to what our customers need. Combine that with industry research and a new product is formulated. This partnership in innovation cultivates a true partnership with our customers, translating their ideas into leading-edge products. Extruded vinyl profiles from Chelsea Building Products combine the reliability and security of engineered strength with the energy-efficient, long-lasting performance and beauty our products add to sliding patio doors and windows used in replacement and new construction across the country.

Everlast Siding is the most advanced composite siding and trim products on the market, produced by combining inorganic minerals, polymer resins, and acrylic. Everlast provides a natural look, more durability, and low-maintenance for end users. These composite siding planks are available in 14 deep, rich colors in 12′ lengths. The proprietary formulation starts with a resilient polymer base combined with an inorganic mineral for long-lasting durability. The acrylic finish is co-extruded with a UV-stable color cap that has outstanding fade-resistance.

Chelsea is always looking for the opportunity to create new and exciting building products. With our custom blend expertise and abilities we can partner with you to develop innovative new products that not only stand the test of time and, but will also add to the beauty of your project's outcome. We offer dozens of popular exterior trim products in a variety of shapes and sizes, including casings, trim profiles, sills, brickmoulds, and other fenestration components. Produced using the finest exterior-grade PVC material, our cellular profiles are used to create traditional stock moulding, casings, crown moulding, shutters, as well as specialty applications, such as gutters and railings.
