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.

Note:

1. Cable resistance must be tested before, during and after installation for warranty coverage

2. All wiring connections should be completed by a certified electrician

Notes:

• Recommended nVent NUHEAT Cable spacing is alternating 2-3-2 pillar spacing which produces 12 W/ft2
• 2-pillar spacing produces 15 W/ft2, which is recommended for installations over concrete slab-on-grade or other areas that require more heat
• 3-pillar spacing produces 10 W/ft2, which is insufficient heat output for most applications
