Should have looked into this earlier. i am building my hearth pad for a Regency F2400 tomorrow. The install manual and web site do not list what R value is needed. I am putting the hearth down on a hardwood floor. My plan is 4 sheets Durock, 1/2 " mortar bed with 1/4" ceramic tiles. Think this should be safe but still wanted to know the specs. This should be R 1.16. I also may add a sheet of flashing under the whole thing. Can't get a hold of anyone on the weekends.
TIA for any opinions.
