i did this, got some rockwoll insulation from a local insulation specialist, wasnt very dear (cant remember how much tho) think it was 75mm thick but you will have to check with a supplier as i cant remember how thick it was either, i got bats instead of a roll, think they are 1200 x 600 panels so easier to handle, i have carpeted my ply with stuff from work, all helped on the noise front and is quite snug to kip in now, if you do insulate it, hold the insulation in place with gaffa tape then fit your ply. will make it loads easier
