About This Product
Uncoupling and Crack Isolation for Tile Floors
Nuheat® Membrane Sheet is a tile underlayment designed for uncoupling and crack isolation over suitable subfloors. It reduces the risk of tile cracking caused by movement in the flooring assembly and achieved a High Performance rating under the ANSI A118.12 System Crack Resistance test.
Integrated Installation with Nuheat Cable
The membrane is designed to accommodate Nuheat Cable, the cold lead joint, end seal, and sensor probe without cutting or modifying the membrane. Cable spacing can be adjusted to provide 10, 12, or 15 W/ft² heat output, allowing the underlayment and electric floor heating system to be installed together.
Standard and Peel & Stick Installation Options
Standard Membrane is compatible with modified or unmodified thinset and can provide waterproofing when installed with waterproofing seam tape. Peel & Stick Membrane eliminates the thinset installation step beneath the membrane, installs 40% faster, and prevents thinset from oozing through membrane seams.
Subfloor and Tile Assembly Performance
Nuheat Membrane can replace one layer of plywood or cement board in the subfloor assembly. Standard Membrane achieved an Extra Heavy rating in the ASTM C627 Robinson Floor Test, while Peel & Stick Membrane achieved a Moderate rating.
Common Questions
Frequently Asked Questions
What is Nuheat Membrane used for?
Nuheat Membrane is a tile underlayment used for uncoupling, crack isolation, and installation of Nuheat Cable over suitable subfloors.
What is the difference between Standard and Peel & Stick Nuheat Membrane?
Standard Membrane is installed with modified or unmodified thinset and can provide waterproofing when used with waterproofing seam tape. Peel & Stick Membrane uses an adhesive backing and installs 40% faster without thinset beneath the membrane.
Can Nuheat Cable be installed directly into the membrane?
Yes. The membrane accommodates Nuheat Cable along with the cold lead joint, end seal, and sensor probe without requiring cutting or modification.
What heat outputs can be achieved with Nuheat Cable in the membrane?
Nuheat Cable can be installed at varied spacing to provide 10, 12, or 15 W/ft² heat output.
Does Nuheat Membrane provide crack isolation?
Yes. Nuheat Membrane reduces the risk of tile cracking caused by movement in the flooring assembly and achieved a High Performance rating under the ANSI A118.12 System Crack Resistance test.
Is Nuheat Membrane waterproof?
Standard Nuheat Membrane provides waterproofing when installed with waterproofing seam tape.
How much area does one Nuheat Membrane Sheet cover?
Each 3'3" x 3'3" sheet covers 10.6 square feet.
