In this scenario a rigid foam insulation is usual and as you d want the same u value in the roof we need the same thickness of insulation 180mm. The higher the r value the better the thermal performance of the insulation. Insulation is laid on the concrete and covered with a screed. Without lifting solid floors it s difficult to introduce any permanent thermal insulation but coir or other breathable floor coverings can help.
