The Watts Radiant HeatWeave mats can be used with a variety of flooring materials including tile, concrete, stone, laminate, vinyl, hardwood, and even low R-value carpets. Regardless of the flooring materials being used, it is critical to ensure the mat is full encased in a layer of thin set mortar. I would also suggest contacting the manufacturer of the specific flooring material you plan on using as some manufacturers will have specific guidelines or restrictions that must be observed. Vinyl flooring, porcelain tile, and concrete will provide the least resistance to heat transfer.
