I am in the process of building an extension and what was a ground floor playroom will become my hall way. The existing floor is a concrete slab with minimal insulation and needs to be raised by approximately 70 mm.
I would like UFH but as the insulation is not great would I be heating the ground rather than the screed and with out smashing it out and starting again I don't have a lot of play.
I think my options are UFH in about 70mm of screed or 50 mm insulation and chipboard over and then rads.
Opinions invited.
