Hi all. I've recently re insulated the loft in my new house to 300mm raising the joist and boarding over with loft boarding. However the old owners or even the owners before them have stuffed fiberglass insulation to the roofing rafters and then plasterboarded and skimmed over. Do I need to rip all this down and get the insulation out as to avoid mould/condensation problems in the future? I had to rip old insulation out of the eaves as it was stuffed in there so now air is flowing under them and into the loft.
