PVC Foam Panels are lightweight, versatile, and resistant to moisture, making them suitable for a variety of marine applications. These panels are often used in interior furnishings, cabinetry, and other non-structural areas where weight is a concern. PVC foam panels are also easy to cut, shape, and install, making them a favorite among DIY boat builders.
5. Honeycomb Core Panels
Honeycomb Core Panels are known for their high strength-to-weight ratio and are often used in constructing high-performance boats and yachts. These panels feature a core made of honeycomb-like structures, usually composed of materials like aluminum, aramid, or polypropylene. The honeycomb design provides exceptional rigidity and impact resistance while keeping the panel lightweight.
6. Thermo-Lite Panels
Thermo-Lite Panels are an innovative type of marine panel made from high-density polyurethane foam reinforced with layers of fiberglass. These panels are highly durable, moisture-resistant, and offer excellent thermal insulation. Thermo-Lite panels are often used when weight reduction is critical, such as in the construction of racing boats and luxury yachts.
7. Coosa Board
Coosa Board is a composite panel made from high-density polyurethane foam and layers of fiberglass. It is known for its strength, durability, and resistance to water, rot, and insects. Coosa Board is often used as a replacement for traditional wood in marine applications, particularly in areas that require structural integrity, such as transoms, decks, and bulkheads.
Benefits of Using Marine Panels
