PROVA FLEX-HEAT® is an uncoupling and crack isolation membrane for tiled floors that includes channels for inserting low-voltage heating cables (sold separately). The underlayment consists of a polypropylene sheet with studs for carrying heating cables, channels for managing vapor, and a polypropylene nonwoven anchoring fleece for securing the membrane to the substrate. The fleece layer is secured with a polyolefin-based adhesive, and it provides shear stress control by neutralizing stress caused by substrate movement. PROVA FLEX-HEAT accepts heating cables up to 5 mm.
- Made of two layers of polypropylene for mechanical bonding, vapor management and Sheer Stress control to neutralize stress caused by substrate movement
- Protects tile or stone floors from cracking as substrates move or settle and accepts heating cables (sold separately) up to 5 mm to create comfort via in-floor heat
- 3.28 in. W x 16 ft. 5 in. L (5 sq m / 54 sq ft.)
- Red primary layer with white fleece bottom layer
- Vapor Management System: Open-air channels beneath the fleece layer provides a path for moisture to dissipate. Well suited for below-grade installations
- 0.26″ (6.5 mm) thick membrane: Can be used without heating cables for matching up to higher floors to achieve a level transition
