Thought of trying aerogel insulation?
Dust free varieties avoid handling issues.
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).
R-value for commercial aerogel insulation is about double rigid
polyurethane insulation, so half the thickness would be about right.

Take care. Thanks, Brian Inglis
