Over 20 years of Innovative Solutions

For over 20 years, Coosa Composites has provided innovative panel solutions for use in a wide variety of industries. Our specialized panels are constructed with high-density, closed-cell, polyurethane foam impregnated with layers of fiberglass to serve as a strong, reliable alternative to plywood and other traditional unreinforced core materials. Coosa’s panels are durable and can withstand even the harshest environmental conditions. The unique construction of Coosa panels provide multiple advantages over honeycomb, unreinforced plastic or foam cores, plywood and other traditional sandwich core materials:

Strong

DURABLE

LIGHTWEIGHT

NON-ABSORBENT

Coosa Panels Offer Many Advantages:

  • 40 to 60% lighter than marine plywood

  • Virtually no water absorption

  • Superior resiliency and endurance

  • Low resin absorption

  • Can be machined using standard wood working tools

  • Will not deteriorate around fasteners due to moisture condensation

  • Dimensionally stable

  • Will not rot

  • Not susceptible to mold, algae or fungus

  • Can be laminated, painted or spray-coated with a multitude of materials

  • Can be attached to other materials using screws, staples, adhesives, and resins

  • Not susceptible to insect infestation

  • Possesses 2 to 3 times the insulating (R-value) of plywood

  • Excellent bonding characteristics

  • Sanded to enhance lamination

  • No special maintenance required

In addition to these advantages, Coosa panels improve several long-run factors in the industries we serve.
