Features & Benefits
Made from thermoplastic continuous glass fiber-reinforced face sheets and polyester foam core, these panels are engineered to provide simplified installation, long-lasting components, and overall cost reduction for boat & RV manufacturers.
These versatile panels can be used in a variety of boat building applications including: interior bulkheads, decking, ceilings, hatches, covers, cabinetry and fittings. The exceptional strength-to-weight ratio provides lightweight yet strong structural performance for increased payloads. And they are resistant to ultraviolet (UV) light, chemicals, moisture degradation, and rot to withstand harsh marine conditions.
Benefits;
- - Ready-to-install: fewer parts and reduced scrap
- - Thermoplastic construction offers strong adhesive properties for easy bonding to various materials
- - Toughness and impact resistance for durability Vibration damping and acoustic insulation to reduce engine noise
- - Dimensional stability for consistent performance in extreme temperature and humidity fluctuations
