I've chased out some redundant wiring from a rendered internal wall and now need to make good. The rest of the render is drummy and loose so ideally needs to be removed before it removes itself. Is putting battens up and plasterboard/skimming an acceptable method in this case? Will this reduce the U value?
The wall to the left of the corner is the neighbours place. The wall to the right is the front of the house (mid terrace Victorian).
