I am looking at the following web site to obtain the insulating base board. Ideally i do not want to have to build a 4 - 6 inch thick perlite or vermiculite insulating layer, and would prefer to use one of the specialist insulating boards plus maybe a couple of inches of the vermiculite or perlite mix.

The question is which board should I use and is the board considered to be superior to the diy V or P mixes?

Superisol 30 ?
Promasil 30,40 or 50 ?
Silica boards ?

I think the superisol 50 will give you the two inches of insulation you need.

wow that was quick.

would I need anything else under the Supersol? or would the 2 inches be enough?

Yes, I have 2 1/2" of a less good (mineral fiber) board, and my support slab hardly gets warm to the touch. That should be good.
