Best For Schluter Membrane: Ditra-Heat Uncoupling Membrane mortar

Buy on Amazon

For a low asking price, ditra-heat uncoupling membrane mortar has managed to overwhelm their customers by packing as many features as they could. It's a great way to get a quality heated floor. The standard Ditra mat is flatter, with more of a continuous checkerboard pattern that provides waterproofing and decoupling) and has rounded studs on the surface to accommodate the Ditra heat heating cable. The Ditra Heat membrane, while a bit thicker (and also providing waterproofing and decoupling) has an integrated fleece backing that bonds the mortar to the ditra and the substrate. The heat membrane is thicker than standard to account for the cables.

The Ditra heat membrane is fairly thick to allow for the wire to be installed in between the octagonal buttons. They want unmodified thinset for use on concrete so that's a money saver. These are good at responding or providing guidance. The product is great and makes installing a warm floor for the first time very easy.
