Celotex/insulation for shed (BN2 Hartington road)

Hi there

I've been putting up a shed this summer (with help from a number of people on here) and was wondering if anyone has any of the following so I could insulate it for the winter?

Rockwool, Celotex board, insulation foam (with the silver on it), PIR boards

Anything like that would be very gratefully received!

Thanks!
