Nuheat Membrane is a uncoupling tile underlayment designed for crack isolation, and simplified installation of Nuheat Cable. It uses a polypropylene sheet with square pillars bonded to a non-woven fabric layer, allowing thinset to anchor securely to the substrate. The structure supports vapor management and can provide waterproofing when installed with seam tape.
Key Features
- Uncoupling and Crack Isolation: Helps reduce tile cracking and meets ANSI A118.12 High Performance rating.
- Simplified Cable Installation: Accommodates Nuheat Cable, cold lead joints, end seals, and probes without modifications.
- Vapor Management: Square pillar design allows moisture to escape during curing.
- Waterproofing Capability: Provides waterproofing when installed with waterproofing seam tape.
- Subfloor Replacement: Can replace one layer of plywood or cement board in approved assemblies.
- Heating Flexibility: Supports Nuheat Cable spacing for 10, 12, or 15 W/ft² output.
- Thinset Compatibility: Works with both modified and unmodified thinsets.
- Load Rating: Achieves “Extra Heavy” rating in ASTM C627 Robinson Floor Test.
