Permat Tile Underlayment

The Blanke PERMAT is an innovative uncoupling tile underlayment that offers all the labor saving benefits of the old plastic tile underlayment roll systems. The Blanke PERMAT also adds support to wood substrates thereby 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. Strengthens wood substrates, Reduces vertical subfloor movement (deflection), Superior compressive strength, Top Mesh: Extruded twisted strands of highly alkali resistant glass fiber heat welded to the lower layer of high-density polyethylene (HDPE) mesh, Bottom Mesh: Extruded twisted strands of HDPE, Fabric Material: Polypropylene fleece, Thickness: Approx 3.3mm (1/8"), Joists spaced 16" o.c. and 19.2" o.c. : Minimum 3/4" thick subfloor, Joists spaced 24" o.c.: Minimum 3/4" thick subfloor plus second layer of 3/8" thick plywood or OSB, Permat provides excellent protection against damage caused by stress cracks and lateral movement typically found in cement substrates, Self-seaming panels prevent substrate movement stress from transmitting to tiled surface, Superior tensile strength, Permat has a 10-year warranty against damage caused by excessive vertical subfloor movement (deflection), the only such warranty in the industry. Whether installing stone on wood or cement subfloors, homeowners who include Permat in their stone and tile installations can rest assured their subfloors will indeed support the installation.
