Is Rmax Thermasheath-XP an acceptable alternative to Dow Thermax?

I intended on using Dow Thermax for an exposed basement application in a residential setting.
I thought there were no alternatives without using an ignition barrier (drywall) but recently came across Rmax Thermasheath-XP. For my purposes, I believe this would be a more affordable option.

Does anyone have any experience with this product? It seems to have similar properties to Dow Thermax. Does Dow Thermax have any documented advantages?
Thanks!!

Natepa,
According to the manufacturer's claims, it should work. But check with your local building inspector before you buy the materials -- just to make sure your inspector agrees.
All of the polyiso manufacturers seem to have an equivalent product.
Some others I've found:
R-Max TSX-8500 & TSX-8510
Johns Manville CI Max
Hunter xci 286
but they seem to be even harder to source than Thermax, which is probably why they aren't mentioned much.
