Is the any comparison between “uncoupling and crack isolation membranes”?
In order to compare these systems we should examine the definitions. Uncoupling systems are defined in the 2003/04 Tile Council of America [TCA] Handbook as follows: “A system that separates the finished surface from the substrate to allow the independent movement between the two and prevent the transfer of stresses to the tiled surface”. Based on that definition, almost any product that separates the two surfaces can be an uncoupling system [e.g. felt paper, carpet pad, duct tape]. Producers advertise that their systems protect tile, but no standards or performance requirements exist.
