Another question about our little boat.
I have been lifting the floor (over the engine) and I'm wondering whether a thin insulation layer is doing any good at all.
The floor comprises three layers:-
- 18mm ply resting on lengths of angle which provides the strength. * 2mm expanded polystyrene with foil on one side * laminate about 6mm thick
Is the expanded polystyrene layer doing any good? I doubt it provides any sound insulation. Is its thermal insulation of any consequence compared with the plywwod + laminate? Finally is it just a standard layer under laminate?
