Coosa Board

Reliable and Resilient

Reinforced Polyurethane Foam (RPF), commonly called "Coosa", is a high-performance composite material combining the lightweight core of closed-cell foam with the strength and rigidity of fiberglass reinforcement. This combination results in a material that is exceptionally lightweight, yet highly durable and structurally stable. The closed-cell foam core ensures zero water absorption, making the material completely rot-proof and resistant to moisture, mildew, and corrosion. These properties make RPF an ideal choice for applications in marine, transportation, architectural, and industrial sectors where strength, weight reduction, and long-term durability in harsh environments are critical.

Sandwich Panel Core

Coosa board makes for an exceptional core in sandwich panels due to its remarkable strength-to-weight ratio and resistance to water, rot, and delamination. Coosa board provides structural integrity while significantly reducing overall panel weight. Its durability and moisture resistance make it ideal for marine, transportation, and industrial applications where traditional wood cores would degrade over time. Using Coosa as a core enhances the longevity, performance, and ease of handling of composite panels.
