Directly beneath the flooring and between the joists fit foil backed insulation boards for example 25mm or 50mm celotex a compressed foam material between silver foil.
Alternatively you could fill the cavity completely using r 38 faced batt insulation.
Cover your insulation with 5 mm 1 4 hardware cloth.
