What We Do

If you are a boat owner, you need to know about marine flotation. Spray foam has become an incredibly popular choice for marine insulation. Our marine spray foam is perfect for insulating, stabilising and controlling condensation in any boat. The closed cell nature of the material guarantees that the foam will not be affected by water making it a must have for all boat owners.

The marine grade foam has excellent thermal properties which allows the boat to stay cool in the summer and retain heat in the winter.

The polyurethane spray is manufactured to a Class 1 fire rating with BS476 Part 1 to ensure the ultimate safety against fire, it is also non-toxic and CFC free.
