Looking for advice regarding decoupling matting - Tile Advice

[Teign Tiler]

Hi Everyone. I'm after some advice with regard large format Tiles with water fed underfloor heating.
I'm about to lay 100m2 of plank style (1500mm x 240mm) on chipboard floorboards with integrated underfloor heating.
I was planning on using Durabase C1++ decoupling matting but saw that it may not be suitable for large format Tiles and their website doesn't say if its suitable for underfloor heating.
Does anyone know if its OK to use or if I need to upgrade to ditra matting although they seem to have the same properties.
Thanks for your time, Gav.

Use cement board.I wouldn’t use matting on timber of any type as it only covers lateral movement. And timber can expand in all directions.

Hi Anthony. Thanks for your advice.
Don't I need to screw the cement board down though ? Or can it just be fixed on a 3mm notched bed of tile adhesive?
Don't want to risk screwing into floor into the wet underfloor hearing. Cheers Gav.

Cement boards need to be screwed down, period. Uncoupling membrane needs no screws.

Self levell the UFH pipes and then fit Durabase on top
