VOTE - Use Hardy backer board OR Ply for base of Travertine tiles

[ferrisbueller]

Hi,

I am looking for views on a decision that I have to make.....

We have a split concrete/floorboard area. For our Travertine floor should we use Hardy backer board OR Ply (width?).

Oh, and just to confuse things does the new concrete area (extension) need some kind of thermal board.

TOTALLY confused so would welcome your opinion.

Thanks

Are the two floors at the same level

what about, hardie on the wood, insulation board on concrete and ditra/durabase over it all?

Dont forget an expansion joint over where 2 substrates join.

Two floors will be level.

What is ditra durabase?

thanks for answers so far.

Ditra and Durabase are similar products and are uncoupling membranes.
