Q&A: What Do You Think About Spray Foam Insulation For A New Aluminum Boat?

Question: We are planning to insulate the interior of our new aluminum boat with spray foam, any comments? Is your hull foamed? Was it primed with paint before or sprayed directly onto the metal?

Answer: Our hull was primed first and then sprayed, but I’m not sure this is really required. Talk to the manufacturer of the foam system. Also, you may want to look at self-adhesive foam sheet systems rather than spray on.
