I need to insulate internally two external walls of my ancient solid wall bathroom.
Any cost affective suggestions would be very welcome.
I have thought about wet wall on top of batoned wall with 20mm insulation board between.
Or tile backer insulation board straight on the wall and then plastered, but not sure if that is possible.
