I am building a hearth pad for the P68 harman. I plan to use 3/4 inch plywood on top of 2 x 4 frame. 3/4 inch plywood on that, then 1/2 inch hardieboard on top. Then I plan to place porcelain tile on top of the hardie board.
Considering they spec only a 20 gauge steel pad, will this layering be sufficient?
Thanks,
Jerold
