Nautical Panels

Our Lightest Fiberglass Composite Panel

Coosa Composites' Nautical Panelnautical1s are manufactured from high density, closed-cell polyurethane foam reinforced with continuous strand fiberglass and can be utilized for multiple applications, including:

  • Marine
  • Industrial / Commercial
  • Transportation
  • Architectural

Nautical Panels have outstanding physical properties from the utilization of continuous strand fiberglass reinforcements. Removing the woven roving layers found in the Bluewater series results in slightly lower flexural strengths, yet lower costs. Nautical Panels are available in densities of 15, 20 and 24 pounds lbs/ft3 (pcf) and sizes: 4 ft. x 8 ft. up to 5 ft. x 12 ft. Thicknesses are available from: 0.25 inch up to 2 inches. Note: Nautical 15 is not available in 0.25 in. or 3/8".
