Recycled PET Structural Sheathing
Introducing a new category of structural sheathing manufactured from post-industrial recycled PET, engineered into a foam-core composite that integrates structural performance, thermal insulation, and air-and-moisture barrier function into a single product.
The Product
The Concord Fiber Group’s recycled PET structural sheathing is designed to replace conventional OSB or plywood sheathing, integrated WRB systems, and rigid foam insulation within a single high-performance panel assembly. The system combines lightweight structural performance, thermal insulation, and integrated air-and-moisture management while utilizing recycled PET feedstocks sourced from established post-industrial waste streams.
The result is a structural sheathing product that delivers air-and-moisture barrier function in the sheathing layer itself, reducing installation labor and minimizing the potential failure points associated with separate housewrap or fluid-applied membrane installation.
Technical Characteristics
Recycled PET foam core utilizing post-industrial feedstocks
CO₂-based blowing system
Integrated air-and-moisture barrier functionality
Dual-barrier seam integration concepts
Non-halogenated fire-resistant surface layers
Target thermal performance of approximately R-5 per inch
Lightweight structural panel architecture
Reduced transportation and installation loads
Target Markets
The product is engineered for new construction across residential, multi-family, manufactured housing, and light commercial markets, with primary near-term focus on manufactured and modular construction. Retrofit applications represent a meaningful secondary market, particularly for envelope renovation projects where the product's consolidated structural, thermal, and barrier function reduces multi-layer installation labor.
Competitive Position
The product is positioned against incumbent OSB and plywood structural sheathing, integrated sheathing-and-WRB systems, and rigid foam insulation boards. Differentiation centers on four primary factors: consolidated structural and insulation function in a single product; recycled-content economics; vapor permeability and air-and-moisture barrier integration; and compliance with evolving EPA regulations on rigid foam blowing agents.
Market Context
Three converging forces create the commercial opportunity for advanced structural sheathing: EPA regulatory action restricting HFA blowing agents in conventional rigid foam products; growing demand for recycled-content building materials driven by both regulation and developer commitments; and persistent supply-chain volatility in commodity OSB and plywood markets, increasing builder interest in alternative materials. CFG's structural sheathing is engineered to serve this evolving market.
Development and Commercial Status
The product is in active commercialization with manufacturing partners. A provisional patent application covering product composition, assembly methods, and manufacturing process is on file with the U.S. Patent and Trademark Office. Production trials are in progress.
