NobleSeal sheet membranes can provide waterproofing and/or protect tile installed over radiant heating systems.  Bond NobleSeal with a NobleBond adhesive and tiling can begin as soon as the membrane is embedded into the adhesive.  NobleSeal SIS will also reduce floor to floor impact noise.

Most manufacturers of "gypsum underlayment" require the following prior to installing tile:

  • Substrate should be dry
  • Gypsum underlayment should be "primed" per manufacturer's instructions 
  • A crack isolation membrane should be installed between the gypsum underlayment and tile

NobleSeal sheet membranes can be installed over primed gypsum concrete and radiant heat systems. Download this chart to learn more about functional capabilities of vairous NobleSeal sheet membranes in these applications:
