The Blanke PERMAT is an uncoupling tile underlayment that offers all the labor saving benefits of the plastic roll underlayment systems. The Blanke PERMAT also adds support to wood substrates reducing deflection and provides greater compression and tensile strength than plastic tile underlayment roll products. The Blanke PERMAT is stable to walk on during installation and does not require additional curing time when installing porcelain with latex modified thinset.
