If I am using Schluter Ditra® as an underlayment, does the SunTouch go over or underneath?
Schluter recommends SunTouch (or any other heating products) to be installed below the Ditra. SunTouch mats are approved for this product/installation. The warm-up time is ever-so-slightly longer due to the air pockets that result when you install the Ditra mat. This allows Schluter Ditra® to effectively isolate the tile covering from the heated substrate, thus preventing thermal stresses from damaging the tile surface. Schluter Ditra® will not inhibit heat transfer or reduce the efficiency of the heating system.
