Hardiebacker under Insulation boards?

[hmtiling]

The latex would spread the load and therefore cancel the point loading issues

I was thinking you were talking of a decrease in point loading Tile size . Ie increase issues

I mean you can use smaller tiles once latexed.

Right this is good, I'm going to glue and screw down my Hardie, then UFH, SLC and tile.

Thanks guys,

It's seems some people love insulation boards and some hate them, my local independent tile shop dosnt sell them and whenever I ask they say theres no call for them as everyone tiles on Hardie.
I have to go to the tile Giant in the next town if I need them.
Can someone explain why it's okay to tile on something so soft like foam cored boards when we do everything we can to make floors rigid?
The smaller the tiles the more likely they would 'sink' into the board.

Glad I found this post ! just had a quote from Andrew at UHeat which includes insulation boards for under the mats. Its for an en-suite 2.0m x 1.6m incorporating a 1000 x 800 offset quad shower with 45mm tray, sink vanity and toilet. I was planning to use 6mm hardiebacker over the existing T&G but then the prospect of introducing 6mm insulation as well confused me. However from reading the above am I right in my understanding that its one or the other, then SLC then tile on top ( Porcelain) . Is there a particular type of SLC or will any suffice.? tia
