That would not make R=2.
Brick can vary in insulating value, but it is somewhere around R=.5 when laid on edge (4" depth).
So you would have to find some Micore to put down first - maybe 1/2 of micore and then some cement board to stiffen it up, and then the brick.
Brick by itself is a poor insulator.

Unless the manufacturer's listing allows an R-value reduction with a layer of sheet metal, you'll need 10" of brick to achieve R-2.
What about this micore stuff? Some members say it's the cheapest way to go. If I could latch onto some micore ...how much and in what order would it satisfy an R-2 requirement

1/2" of Micore is R 1.1
lots of possible ways to encase it, like:
cut carpet
frame wood around outside
lay 1 sheet cement board
lay 1/2" micore
lay 3 sheets cement board - screw everything down to the floor and some glue in between.
ceramic tile to finish.
That would be R-2
If you search the wiki and site for micore, there are even some sources named.
