SunTouch HeatMatrix Uncoupling Membrane Roll 161 Sq Ft for Radiant Floor Heating

SunTouch HeatMatrix Uncoupling Membrane Roll 161 Sq Ft for Underfloor Heating System

Uncoupling Membrane for Electric Radiant Floor Heating Systems

The SunTouch HeatMatrix uncoupling membrane is designed for fast and efficient installation of electric floor heating systems. It provides superior protection for tile surfaces while simplifying the installation of WarmWire heating cables.

Coverage: 161 sq ft per roll

Membrane Thickness: 0.24 inch (6 mm)

System Overview:
HeatMatrix is a flexible underlayment that combines uncoupling, waterproofing, and vapor management in a single system. It helps prevent tile cracking caused by subfloor movement while protecting against moisture and water vapor.

Key Features:

• Uncoupling protection reduces stress from subfloor movement
• Waterproof and vapor management design
• Flexible material for fast and easy installation
• Low memory for easier roll-out and flatter installation
• Compatible with modified thinset mortar
• Durable and lightweight construction
• Designed for use with WarmWire heating cables

Heating Performance Options:

• 2" and 3" spacing: 14.8 W/sq ft
• 3" spacing (standard): 12.3 W/sq ft
• 3" and 4" spacing: 10.6 W/sq ft

Installation Flexibility:
Wire spacing can be adjusted based on heating needs. Use tighter spacing (2" to 3") for high heat loss areas and wider spacing (3" to 4") for lower heat loss areas.

Applications:

• Tile, stone, or laminate flooring installations
• Concrete and structurally sound subfloors
• Residential and commercial applications
• Wet areas when properly sealed with joint strips

Installation Overview:

• Press WarmWire into pre-formed channels in the membrane
• Embed heating wire with polymer-modified thinset
• Install finished flooring over the system

Coverage Calculation:
Measure total floor area and subtract non-heated spaces to determine the required membrane coverage.
