Insulating wall then plastering??

[emphasis303]

Hi

I have an external wall which i want to line with insulated sheets then plaster over.

It is currently plastered however when knocking on it, it sounds hollow.

So what I want to know is, do I get rid of the current plaster, attach the thermal sheets to the wall, then attach plasterboard and then skim it. If this is the way, what should I use to attach the plasterboard to the thermal sheets? Do I need to drill through the thermal sheets and into the wall?? Not sure what is the best way.

If anyone has a better way of insulating the wall in a non cavity way it would be much appreciated


Thank you very much

one more thing is, if i am to be skimming what would be the right tools to be using to do this?

get pre insulated boards and attatch using no-nails or similar construction adhesive and long screws / rawlplugs
