We’ve just moved into a new house and a quick an easy job to get started is to insulate the loft.
iIt currently has loose fill between the 8” joists - does this degrade making it worthwhile sticking new 200mm mineral wool between the joists and 100mm over. Or is it good forever and a bit of 100mm over the top would suffice?
Thanks,
