How Should I Insulate My Garage

I have a single garage which I want to insulate to turn into my workshop for wood working.

The building is currently single brick wall and I want to insulate it but all have it so that it dampens sound for when I’m working tools.

I’ll also look to add more plugs to the work shop as well but will get an electrician to do that.

The garage also has its own circuit breaker within it. I’ll also look to have a/c installed to help with climate control due to pouring epoxy.
