Is this the dogs bollix as flooring for a small trailer.

It will absorb water, although that seems to affect its insulation

Personally, I would use high density polyethylene rigid sheet. I used
it, 25mm thick, for table tops in a clean room as it resists not just
water but a whole range of cleaning chemicals.
