I searched but I couldn't find an answer.
Does it make any difference whether I use 4" or 6" of vermiculite/perlite insulation under the floor? Is there any downside going with 6" as far as placing bricks on top? I understand the R value will increase but is it better than going with the recommended 4"?
Thanks!
