Boat Spray Foam Insulation
Enhance comfort and efficiency on the water with our boat spray foam insulation. Ideal for both leisure and commercial vessels, spray foam reduces condensation and ensures stable temperatures.
The Benefits of Boat Spray Foam Insulation
Spray foam insulation for boats offers a range of benefits, including temperature regulation and moisture control. With the constant exposure to water, boats are prone to condensation, which can lead to rust, mould, and unpleasant dampness. Spray foam insulation acts as a thermal barrier, keeping the interior of the boat warm in winter and cool in summer. This also helps reduce the energy needed for heating or cooling, contributing to fuel efficiency.
Closed-Cell Spray Foam for Marine Use
Closed-cell spray foam is a reliable solution for marine environments due to its water resistance and structural strength. It adheres tightly to surfaces, protecting the hull and inner areas from saltwater and moisture damage. The lightweight nature of closed-cell foam also ensures it doesn’t interfere with the boat’s balance, while providing added durability to the structure.
