Order of installation when using under-tile heating cables and Ditra matting?
Question:When using Shulter Ditra matting to de-couple tiles from a plywood floor should the electric under-tile heating cables be placed under the Ditra or be embedded into a screed on top of the matting? Should that screed then be left to set before laying the tiles on top?

The Ditra goes down first and the cables laid on top. Its usually taped down not put down with a screed.
