Our expertise with polyurethane foam makes us a trusted partner for manufacturers and marine professionals seeking durable, lightweight, and moisture-resistant materials for boats, docks, buoys, and flotation devices.

Marine Applications
The Advantages of Polyurethane Foam
Polyurethane foam is widely used in marine environments because of its excellent buoyancy and high strength-to-weight ratio. Its closed-cell structure prevents water absorption, ensuring the foam remains lightweight and buoyant even when submerged or exposed to water for extended periods. This makes it an ideal choice for pontoons, flotation devices, and ice holds, where water resistance and durability are critical.
Key Benefits of Polyurethane Marine Foam:
- High strength-to-weight ratio
- Moisture resistant with closed cell structure
- Excellent buoyancy for flotation applications
- Durable in harsh marine environments

One Smart Solution
Preventing Corrosion & Mould With Spray Foam Insulation
Beyond buoyancy, our closed-cell polyurethane spray foam also serves as a highly effective insulation material for marine vessels such as houseboats and container homes. When applied to metal surfaces, it prevents condensation buildup that can lead to corrosion and mould damage, extending the lifespan and safety of your marine assets.

Protection Built In
Comparing Marine EVA Foam & Polyurethane Foam
While marine EVA foam is popular for decking and cushioning due to its soft, shock-absorbing texture, polyurethane marine foam excels in insulation, structural support, and buoyancy. The closed-cell nature of polyurethane foam keeps it from absorbing water, maintaining strength and flotation, unlike open-cell foams, which are unsuitable for marine use due to waterlogging.
