Better insulation than fiberglass
(OP)
What are some insulators that have lower conductivity than fiberglass? Something between fiberglass and aerogel basically. Obviously it will cost more than fiberglass, but nothing NASA grade. Temp gradient is 350F to 68F.

A much more expensive alternative is a commercial vacuum insulated panel using aerogel as the fill: http://w

However, for conventional materials, you're pretty much limited to about R-8 per inch. Aerogel is listed at R-10, but the VIPs have sufficiently higher R-values that any nominal degradation would still put you higher than fiberglass.

Most of the other stuff (like polyurethane) won't work because of the temperature requirement: 350F.
