Ditra is good for new concrete. This will reduce heat loss to the concrete substrate and improve the floor warming response time. Ditra heat tb has additional insulation for going over concrete floors. Un modified under and over the ditra.

The schluter ditra uncoupling membrane is specifically designed to allow the installation of ceramic and stone tile over any even and load bearing substrate. We recommend using schluter ditra heat duo uncoupling membrane. Megabond from lowes or kerabond are good un modified thin sets. The ditra heat duo offers the same functions as the schluter ditra heat membrane but also features an integrated thermal break in the form of a thicker bonding fleece.

Its primary function is to help neutralize stresses in movement between the substrate in my case the subfloor but it can also work with osb or plywood and the tile. The combination of these four essential functions allows for the successful installation of tile over a wide range of substrates including plywood osb concrete gypsum heated floors etc. Ditra is essentially a molded plastic sheet with fleece backing.
