Be careful not to over-insulate the oven -- it depends on a certain 
amount of heat flow to ambient to balance the heater.  The stability 
of the heater control loop depends on having the correct amount of 
thermal resistance from oven to ambient (also, on the thermal 
resistance being distributed similarly to the original scheme).

Best regards,
