This was atopic I was leading into with my polypipe UFH post a few weeks back.

I don't know if it's people not understanding it's actual usage, or maybe being misinformed. But it's for lateral movement not defection. (not that I'm saying a backer is)
If the chipboard still has bounce then ditra is money down the drain.

Small pun there.

What was the reason/symptoms of failure on the one you looked at @Bri?

Deflection, chipboard was just nailed to the joists and had worked loose over a short period of time, most of the grout had either hairline cracks or had big chunks missing.

I've used Ditra before on a bathroom floor 2.5sqm. no deflection and screwed down. Ditra, rapid set flex and rolled using an amtico roller. I would only ever do this is a very small area where there is not much foot traffic.

Deflection, exactly. No amount of ditra would of helped. Had a backer been used instead the likelihood is that by glueing and screwing them in would of provided enough stability for the floor to be tiled.

Ditra over chipboard doesn't get you away from the fact that chipboard is a load of tosh in the first place.

Timber floor, backerboard
SLC, screed, stone or anything heated. Ditra
