Travertine tiling on a screed that has piped underfloor heating. Im using an s2 adhesive but should I overlay with Ditra 25 as a precaution?

Isn't S2 the industry standard for underfloor heating or floor with possible movement? Happy to be educated if Im wrong.

S1 is fine.. you don’t need the deformability of an S2 on a solid screed .. i was just asking thats all 👍
