PROVA FLEX-HEAT® is an uncoupling and crack isolation membrane for tiled floors that includes channels for inserting low-voltage heating cables (sold separately). The underlayment consists of a polypropylene sheet with studs for carrying heating cables, channels for managing vapor, and a polypropylene nonwoven anchoring fleece for securing the membrane to the substrate. The fleece layer is secured with a polyolefin-based adhesive, and it provides shear stress control by neutralizing stress caused by substrate movement. PROVA FLEX-HEAT accepts heating cables up to 5 mm.
