I'm having some work done and have had the wall stripped back to bare brick. I want to avoid dot and dab or a stud frame with plasterboard if possible. What other options are there to finishing off the wall so it's strong but still insulated? One builder told me he would cement render the walls, apply a wire mesh and the plaster/skim on top. Does this sound ok? The walls are old double skinned brick walls with no insulation in between.
