We have just bought old, cold farmhouse with zero insulation anywhere. While we plan to strip off lathe and plaster on the external walls, we are undecided as to what to do with the remaining internal walls. Other half wants to strip off lathe and plaster from all walls, insulate, and then plasterboard.. I wonder if using cavity insulation and then skimming over uneven lathe and plaster would be sufficient to insulate?
Thanks for any advice,
