We have no basement - therefore it is against soil. 8 cm now, 12 cm were planned. However, due to the insulation under the floor slab, it is still well below the minimum requirement of the energy saving ordinance. Less on the upper floor simply because for equally heated rooms only a U-value of 0.75 W/m*m K is required. That would be 4 cm WLG 0.04.
