Chipboard floor and ufh, advice please.

[jerry]

Hi folks
Im new to the site and looking for thoughts on the above.
The job is a hallway leading into a kitchen/extension. About 50sqm. The floor is 22mm chipboard fixed directly to joists, although they seem to have put in extra noggins and tightened the floor up pretty well I have no real experience of chipboard.
I am a big fan of Ditra mat but wonder if this would be enough. The heating mat would go onto the Ditra, the Ditra glued to the chipboard.
Any thoughts greatly welcome.
Thanks
Jerry

As far as I'm concerned, Ditra should go closest to the tile to benefit from its uncoupling properties. I would:-
Insulation board
UFH mat
Latex
Tile
I'd add Ditra if I was fixing stone.

As above.....
