Hi all, my question, I hope, is simple enough.
I am building a conservatory and the slab was laid today onto hardcore with a Dpm.
I want to use celotex insulation, but what is the way to go forward as I seem to be getting conflicting views on putting the celotex on the screed or screed on the celotex.
How should it be done for best results. Also what thickness celotex would be best to use. I'm in south east England, so extremes of weather are quite rare.
Thanks for your help.
