Membrane is a tile underlayment and uncoupling membrane.

Membrane can replace a second layer of plywood/concrete board and reduces the risk of tile cracks caused by movement in the flooring assembly. When integrated with Cable, the Membrane system is a best-in-class integrated uncoupling, waterproofing, and floor heating solution. Membrane eases the installation of Cable by simplifying the installation process.
