Hello,
I have insulated my shed with celotex board. However when it comes to the floor, the shed is already installed and I cant uproot it. It is sat on a concrete bass with wood panels as the floor presently.
I have about 3.5cm to play with but my options are limited. Can you lay celotex and then some kind of hard floor directly on top of it? I dont have the luxury of joists that you can insulate between and then cover...
