When warming along with polystyrene, they often use such material as mineral wool. Insulation is most often done inside, although there are cases that insulation is exclusively outside the structure. Technologically, mineral wool has such a sequence — foam, then there is a special protection against wind, materials for performing high -quality vapor barrier, crate, counterpart, special ventilation system, then there is a special lining and a drainage system. If your type of roof is soft, then in this case it is best to use several layers of such mineral wool at once, which should be located with rafters in a row. To make a crate, chipped slabs are most often used, which is processed with special impregnations to significantly increase waterproofing. Correctly performed ventilation needs to be paid special attention, because if it will be poorly made, then you are threatened with the fact that there will be an accumulation of fungal parasites and mold.
