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.
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.
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 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.
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.
By virtue of the fact that boats are going to be located on the water, in sometimes very wet and harsh environments, we would usually always recommend that a Closed Cell insulation is used. It’s high density, strong adhesion makes it the obvious choice.
Open Cell can be used in some circumstances, particularly on house boats where the construction is a timber frame and the boat will sit in one place without battling variable weather patterns. Open Cell could also be used on internal rooms to provide sound proofing solutions.
Yes, we would always usually recommend the insulation is covered in marine environments. Both for fire safety measures and also to protect the insulation from moisture or damage. We can install a Class 1 fire rated foam but it should be covered with an ignition barrier.
Many boat builders will cover with ply or plasterboard but it’s always worth checking whether this is compliant enough for a boat, particularly as it can be a confined space, difficult to evacuate in an emergency. We can help you choose the right solution.
No. The spray foam is applied directly to the substrate which means there is no opportunity for any moisture to form and sit between the insulation and substrate. There should be no risk of moisture forming within the fabric of the boat structure.
Ventilation is important in confined spaces and we also recommend that a vapour control layer is added to the insulation once in-situ. The vapour control layer will act as a protective layer to prevent any internal condensation from entering the insulation and damaging the structure.
Not only does the performance of Spray Foam Insulation surpass pre-manufactured insulators such as Fibre-based or Rigid-PIR, it is incredibly quick to install by our experienced team. This can help to rapidly speed up a project.
With many boat surfaces being curved or angular, traditional forms of pre-manufactured insulation can be hard to fit, leaving the vessel with pockets of un-insulated areas. Spray Foam Insulation adheres to the substrate and overcomes this issue in a quarter of the time.
