Product Description:

SunTouch HeatMatrix membrane provides a high-performance uncoupling, waterproofing, and crack isolation solution engineered to safeguard your tile installation and enhance the performance of SunTouch WarmWire electric radiant floor heating systems. Designed with a durable polypropylene structure, HeatMatrix minimizes lateral substrate movement, prevents tile cracking, and distributes point loads evenly to create a stable foundation for ceramic tile, porcelain tile, stone tile, marble tile, and other premium floor coverings. This innovative flooring underlayment incorporates a one-ply, non-woven fleece underside that promotes superior mortar adhesion while absorbing multi-directional stresses caused by subfloor expansion and contraction.

HeatMatrix is ideal for residential and commercial installations, supporting structurally sound subfloors such as concrete, plywood, OSB, existing tile, laminate, and stone. It can be used in both heated and unheated applications, providing full-coverage crack isolation and a reliable water barrier for moisture-sensitive areas such as bathrooms, kitchens, showers, laundry rooms, basements, sunrooms, and entryways. The membrane features integrated channels specifically designed for WarmWire electric heating cables, allowing simple press-in placement and adjustable spacing to accommodate custom heating layouts. This makes it possible to target areas of high heat loss like sunrooms or provide even warmth across bedrooms, dining rooms, and living areas.

Installation is quick and intuitive: press WarmWire cables into the HeatMatrix channels, then embed the membrane using polymer-modified thin-set mortar before laying your chosen flooring. Calculating coverage is simple by measuring the wall-to-wall area of the room and subtracting any zones not receiving tile. Whether you are upgrading a small bathroom heated floor, renovating a kitchen tile system, or undertaking a full home improvement project, HeatMatrix delivers the flexibility, strength, and long-lasting comfort required for both DIY and professional tile installations. Designed to support modern home decor and construction needs, HeatMatrix ensures reliable radiant heat performance and a stable tile surface for years of comfortable living.
