I remember some news about fires on passager ships
that the toxic fumes of burning or heated insulation material
was one of the main cause of casualities.
Check the materials you want to use.

Hi,

I'm about to start building a 37ft Van de Stadt from an aluminum kit. One
area of boatbuilding that seems to get skimmed over in all books is
insulation.

I have access to sheets of polystyrene. Is this any good for metal boats? Or
should I stick with polyurethane?

I'm also investigating a Swedish product called Moniflex which is used
extensively in passenger trains because it's light, fire-resistant and
flexible, which sounds perfect for boats. Does anyone know anything about
it?

Many thanks
