I believe that will be a non-insulating & fairly high mass refractory material, equivalent to the heavy fire brick when cured
but I have not used it... So can't be sure.

I'm not sure what part of the country you are in, but here in Oregon, the best prices I've seen for castable and other refractories is "hi-temp Inc" out of portland. They have an eBay store, and as is usual for these things, shipping is the killer if you can't pick it up will-call.
They have Kast-O-lite 30 which is an insulating castable... Good to 3000F
The castables they sell are oriented toward kiln making and they have both light insulative and heavy more structural types.
