How thick is DCM-PRO?
DCM-PRO Peel-And-Stick Membrane
The DCM-PRO membrane (red material) is 1/4″ thick. The heating cable (blue), which fits within the membrane, is 3/16″ thick.
Warmup recommends creating a channel for the heating cable factory joint in the membrane so that it can lay flush. Once the membrane, heating cable, and floor probes are down, it is necessary to fully embed the materials in thinset or leveler.
