Marine & boat insulation

Polyurethane sprayed foam insulation is now the number one choice for boat insulation, especially amongst canal boat owners and enthusiasts. There are many reasons for this, which mainly lie in the extensive benefits offered by the lightweight and unique nature of the foam substance.

The Webtherm spray foam system goes onto surfaces in a liquid form, and then, within seconds, expands to the required thickness, setting rapidly into a rigid foam form. This means that a continuous membrane can be achieved, therefore filling in all gaps, eliminating draughts and further possibilities of conducting cold air. So besides having the most thermal efficient properties in itself, it contains these added energy saving advantages.

Insulation effectiveness is judged and measured in terms of 'u' values. Spray foam boat insulation has extremely good 'u ' values or thermal efficiency. For example, when comparing PU foam to 'Rockwool', almost three times the thickness of 'Rockwool' would be needed, compared to foam, to achieve an equivalent 'u' value. Foam, then, is the obvious choice in confined areas such as boats as it is also space saving.
