Trusted PVC & Composite Building Material Supplier Since 1975
Since 1975, Chelsea Building Products has been a leader in designing and extruding PVC and composite profiles for the building materials industry. Our commitment to quality, customer service, and innovation has remained constant through decades of growth and ownership changes. Originally founded as Poly-Tex Company in a Pittsburgh suburb, we pioneered vinyl window profiles in the U.S. after being acquired by Chelsea Industries in 1980 and later joining the aluplast group in 2017. Our 50-year legacy includes developing industry-first products like C CORE composite reinforcement and Everlast Advanced Composite Siding. We maintain a global footprint while expanding capabilities through strategic investments like our 2018 Greenville, TX facility and upcoming second extrusion plant near Pittsburgh.Our technical expertise spans material science, extrusion tooling design, and color solutions, supported by an NFRC-certified thermal simulation specialist. We provide value-added services including product engineering, technical support, certification testing, and marketing assistance to fabricators and distributors nationwide. Our 2023 land acquisition for a new Pennsylvania facility demonstrates our ongoing growth strategy to better serve southern and western markets. Customer testimonials consistently highlight our product consistency, responsive service, and accessible team culture that builds lasting partnerships.

Services
PVC Extrusion
We produce precision PVC extrusions for window and door systems using advanced material science and proprietary formulations. Our process ensures consistent quality across replacement, new construction, and commercial applications while meeting thermal, structural, and impact requirements. With 50 years of expertise, we create both standard and custom profiles that exceed industry performance standards.
Composite Materials
Our patented C CORE technology provides non-metal composite reinforcement for vinyl windows and doors. This thermally efficient alternative to aluminum improves energy performance while maintaining structural integrity. The same material science powers our Everlast Advanced Composite Siding for durable exterior applications requiring both strength and aesthetic appeal.
Color Solutions
We offer extensive color customization including standard beige, cocoa, and brown options plus durable lamination processes for special requirements. Our heat-resistant lamination provides both interior and exterior color choices with wood-grain finishes that outperform traditional capstock methods while maintaining long-term durability in various climate conditions.
Thermal Certification
Our NFRC-certified thermal simulation specialist supports product development through R&D collaboration and independent agency partnerships. We maintain Code Compliant Research Reports for major building codes including International, Florida, and Texas standards. This ensures our products meet energy efficiency requirements for different climate zones and regulatory environments.
Technical Support
Our technical service team provides comprehensive support from product understanding through installation and ongoing maintenance. We offer best practices guidance, startup assistance, and issue resolution with rapid response times. This hands-on support extends to workflow optimization, equipment consultation, and performance analysis for manufacturing partners.
