Summerhouse

I'm looking at building a summerhouse on top of a existing decking.

The existing decking has been raised off the ground, with dpc on top of the joists, then the decking boards.

I look to build a sub floor on top of decking, then the summerhouse on top.

When building this sub floor (bearers), would you insulate this with celotex, then put the summerhouse floor on top?

Thanks
