Wood stove hearth

[Jrous]

I’m looking to build a hearth for my wood stove I need an r rating of 1.2 I plan of using cement board and tile but that’s not going to be enough r value just wondering what else could I use. Thanks in advance

Any limits on thickness? 4 layers of Durock will get you there. This is a good reference for other options.

My wood stove requires floor protection with a certain R value. Where do I find this rating?
