Boat & Marine Spray Foam Applications

From fishing trawlers to canal vessels, boats come in all shapes and sizes, many with curved steel surfaces. In many circumstances, the available depth in walls, ceiling or floors is minimal, therefore, using an insulation product that offers one of the most effective thermal performances per inch is critical.

The speed of application of spray foam coupled with its airtight performance and seamless adherence to a variety of surfaces makes it the optimal solution when considering insulating your boat. In damp, cold environments, spray foam provides the thermal envelope required.

Dependent on the structure of the vessel and materials used, we usually promote a Closed-Cell formula such as ThermoFoam CC-2000 thanks to its multitude of capabilities in marine environments.

High density foam such as Closed-cell provides a strong bond to the surface on which it’s applied. The closed-cell nature of the foam means that it offers an exceptional barrier against vapour transfer and therefore does not hold or trap moisture.


Insulation

Canal Boats
Traditionally a metal structure, canal boats are popular but not always the warmest. With little or no insulation and a lack of ventilation, internal heat can quickly form condensation against cold metal surfaces.

25-50mm of Closed-cell will significantly reduce the impact of this thermal bridge to offer a great thermal envelope to reduce heat-loss and prevent structural rust.


Fishing Boats
These large and imposing vessels operate in harsh environments. Similarly to canal boats, they are often made from metal therefore require good insulation, particularly in the storage and living areas.

The metal wall studs typically allow for 50-100mm of insulation which is why we recommend Closed-Cell to maximise the thermal performance in a limited space.


House Boats
House boats offer a unique style of living although their exposure to harsh environments can leave them cold and at risk of damp and mould.

Constructed much like a standard house, most house boats are made from wood and are therefore suitable for both Open or Closed-Cell ThermoFoam, installed at compliant depths.


Open-Cell vs Closed-Cell
(In moisture rich environments)

Although we install both open and closed-cell products, not all spray foams are created equal, therefore we are always careful to respect the application uses for both products in achieving the correct install for your building.


We use the team at ThermoFoam regularly as their solutions are able to insulate areas effectively and with speed. Having worked on numerous projects with the team, we always have the confidence that the end result will match our specifications.
