floor insulation options

[jimkramer]

It seems these are the most readily available options for insulation below the cooking floor (besides Vermicrete, which I will not be using):

FB Board
SuperIsol
Insblock (did I get the name right?)

Are there any other options ? Which one did you use? Are you happy with it? I'd like to call it a day and get the FB board, but the shipping to NY is expensive.

Foam-glass.

4 inches vermiculite 5:1 portland cement mix.

This will be the least expensive and probably the most commonly used option.
