I am currently adding insulation to my icebox. I am doing this in place,
because it is difficult to remove existing cabinetwork without wrecking it.

Basically, I will use sheet foam where I can get at surface - probably
polyisocyanurate with foil on it. Elsewhere, I will pour in urethane foam.

I am concerned about the flammability of these products. Are there
regulations for boats as there are for homes that require the foam to be
covered with a fire barrier? What is recommended?

My box will end up with 1/2" plywood as sheath on two sides. The back is a
large cavity with hull as outside. The front and bottom are exposed and
should probably be covered. The insulation has an aluminum foil, but I doubt
that provides any flame resistance. Thinking about just using 1/2" plywood -
Would this be acceptable to a surveyor?

No, there are no regulations or standards for pleasure boats that
require them or parts of them to be fireproof. If the boat is
fiberglass, the resin is about as flammable as anything you can think
of....

Then there's cushion foam, synthetic upholstery, all that wood.
