Is home insulation board (PU) similar to that used in surfboard blanks? Is the density similar? Can it be planed? Thinking of making a board this summer for the craic. Stringer too.

It’s a different lighter density and will turn yellow it can be used but will need to be reinforced to hold up in any way

Cool appreciate the heads up 😀.
I was considering cutting a sheet of 8 x 4 / 4" Polystyrene/eps and trying epoxy resin. I'm making up a hot wire cutter to shape it.
The guys in Seabase.eu have blanks from 160 bob. They do kits and all the bits. I was weighing up the pros and cons.

Thanks again.!
