The Concord Fiber Group’s hemp composite board technology utilizes extrusion and co-extrusion manufacturing systems to produce engineered structural panels designed for moisture resistance, fire-resistant assemblies, dimensional stability, and other targeted performance requirements.

The Technology

Concord Fiber Group’s hemp composite construction boards are manufactured through patented extrusion and co-extrusion processes that combine refined industrial hemp fiber with engineered thermoplastic binders to create application-specific composite panel structures. Unlike conventional commodity construction boards manufactured around fixed material properties, CFG’s co-extrusion technology platform is designed to allow performance requirements — including moisture resistance, fire resistance, thermal performance, impact resistance, and dimensional stability — to be engineered directly into the panel architecture through tunable multilayer composite structures.

The resulting boards are intended to provide combinations of structural, thermal, moisture-resistant, and durability characteristics not typically associated with conventional wood-based construction materials or traditional natural-fiber composite systems.

The technology is the result of multi-year materials development work focused on a consistent thesis: that commodity construction boards represent a significant opportunity for higher-performance composite alternatives manufactured at competitive cost.

Patent Portfolio

The hemp composite construction board platform is protected by three issued U.S. patents covering extrusion and co-extrusion manufacturing systems, composite board architectures, material formulations, and related structural panel technologies for composite construction materials. Additional patent applications related to extrusion-based composite construction technologies and integrated structural panel systems are currently pending.

Performance Properties

• Structural performance comparable to conventional structural sheathing

• Moisture and water resistance

• Fire-resistant assemblies through formulation and multilayer composite design

• Mold and biological resistance

• UV stability for exterior exposure

• Acoustic performance potential

• Impact-resistant configurations for specialized applications

Formulations can be adjusted to prioritize different performance characteristics based on application requirements, certification standards, and regional market conditions.

Target Applications

Hemp fiber composite construction boards are engineered for the following primary applications: roof underlayment, subflooring and exterior wall sheathing in residential and light commercial construction.

Additional applications — including interior wall systems, decking, and specialty industrial uses — are also within the technology's addressable scope and protected by our patents.
