Spray Foam

Our Service

Polyurethane Foam is used in numerous marine applications. The high strength to weight ratio plus its excellent buoyancy properties makes it an excellent choice as an integral part of the manufacture of boats, Ice Holds, buoys, docks, and flotation devices.

Product Description: Marine Foam Insulation

We have been involved in many projects using our foams for various purposes in the marine industry, ranging from its use as a lightweight closed cell filler in pontoons to insulation in house boats. Due to the closed cell nature of our spray foams, they do not absorb moisture, so will not become waterlogged, even if exposed to water consistently, or submerged.

Similar to its use as an insulation material in container homes, using spray foam on metal surfaces prevents condensation from occurring, which in turn prevents corrosion and mould from causing damage.

Marine Foam FAQs

Polyurethane foam is used in numerous marine applications due to its high strength-to-weight ratio and excellent buoyancy properties. It is commonly used in the manufacture of boats, ice holds, buoys, docks, and flotation devices.

Polyurethane foam’s closed cell structure ensures it does not absorb moisture, making it ideal for marine environments. Even when consistently exposed to water or submerged, the foam will not become waterlogged, unlike materials like expanded polystyrene.

Closed cell polyurethane foam, when used as an insulation material on metal surfaces, prevents condensation from occurring. This helps in preventing corrosion and mould, which can cause significant damage to metal structures, such as those in container homes, sheds and houseboats.

Yes, closed cell polyurethane foam is often used as a lightweight closed cell filler in pontoons and similar structures. Its durability and buoyancy make it an excellent choice for such applications.

High-density polyurethane foam offers superior strength and durability, making it ideal for applications requiring robust and long-lasting materials. Its closed cell nature also ensures that it remains buoyant and does not absorb water.

Marine EVA foam and polyurethane marine foam serve different purposes. Marine EVA foam is often used for decking and cushioning due to its softer texture, while polyurethane marine foam is used for insulation, buoyancy, and structural support due to its strength and closed cell properties.

Closed cell marine foam is preferred because it does not absorb water, maintains buoyancy, and provides excellent insulation. This type of foam is durable and resistant to moisture, making it ideal for harsh marine environments. Open cell foam is not suitable for any marine applications due to its tendency to get easily waterlogged.

Marine foam blocks are used in a variety of applications, including buoyancy aids, flotation devices, and structural components in boats and docks. Their high strength-to-weight ratio and moisture resistance make them highly versatile and reliable.
