I'm rebuilding my MES 40 and basically only keeping the cabinet itself and the heating element. Using an Auber 1520 PID controller, an Auber circulation fan, and adding a rotisserie as well. The insulation on the back is mostly good but is uneven and bulged out in some spots so the back cover does not close flat. Can I just rip this insulation out and replace it with something else that can be cut to the right size and shape? I'm hoping there is something I can just go pick up at the local hardware store. What would you suggest using?

Pulled the trigger on a 48"x24"x1" Pre-Cut Ceramic Insulation 8lb 2300F - between this and the PID it should give me many more years of use!
 
Let us know how this works out. Not the first time this has come up. I had doubts being we are talking temps well below where the ceramic was intended to work, still might though.
