Prova TT8006RED15 Flex-Heat, Lightweight Floor Heating Uncoupling Waterproofing Membrane, 161 Sq Ft Roll, Underlayment for Radiant Heating Systems, Ceramic Tile and Natural Stone Tile, 9 Rolls Bundle

Product Features:

• 9 Rolls Bundle, Coverage of each roll is 161 Sq Ft
• Prova TT8006RED15 heating membrane features a deep groove design with integrated locking channels that accommodate multiple thicknesses of electric floor heating cable, allowing flexible cable spacing and secure cable placement.
• Provides exceptional versatility as a tile underlayment by combining uncoupling, heating cable support, vapor management, and load distribution in a single system.
• This uncoupling membrane with heating cable capabilities incorporates a proprietary Shear Stress Control system with a non-woven anchoring fleece backing that helps neutralize stress caused by in-plane movement of the substrate.
• Prova TT8006RED15 is approximately 0.24 in (6 mm) thick and supports vapor management while contributing to waterproof floor assemblies when seams and penetrations are properly treated with compatible waterproofing accessories.
• Can be installed without heating cables when needed, making it suitable for height-matching adjacent floors and achieving smooth, level transitions between different flooring surfaces.
• The heating membrane provides superior point load distribution and enhanced resistance to compression during tile installation, helping support heavy loads and reduce stress on grout joints.
• Compatible with a wide range of in-floor tile installations, including ceramic tile, porcelain tile, natural stone tile, marble tile, and other common stone and mosaic flooring materials.
• Constructed from durable polypropylene, the membrane helps protect the substrate from moisture intrusion and water exposure, contributing to long-term floor durability and protection against water-related damage.

Product Description:

Prova Flex-Heat is a lightweight uncoupling membrane providing exceptional versatility in tile underlayment applications. The Prova Flex-Heat system is a highly multi-functional tile underlayment designed for use with electric radiant floor heating systems. Featuring a deep groove design, the membrane accommodates multiple heating cable thicknesses and layouts, allowing for flexible cable spacing and efficient heat distribution. The integrated vapor management system and shear stress control design deliver reliable anti-fracture protection and uncoupling performance, helping reduce stress transfer from the substrate to the tile assembly. Once installed beneath a tiled floor, Prova Flex-Heat helps ensure long-lasting warmth, structural stability, and durability for years of use.

The membrane features a one-ply non-woven fleece backing that bonds securely to the substrate and helps neutralize stress caused by in-plane movement. This uncoupling layer enhances crack isolation performance and supports tile longevity over a variety of subfloor conditions. The stud-and-channel cavity structure promotes mechanical bonding between the membrane and thin-set mortar, allowing the tile assembly to move independently from the substrate while maintaining a strong load-bearing surface. Prova Flex-Heat is engineered for versatile heating cable compatibility and supports multiple wire sizes up to 0.2 in (5 mm) thick, making it suitable for a wide range of electric floor heating cables used in commercial and residential applications.

The integrated cavity geometry supports even heat transfer while allowing excess moisture vapor to dissipate beneath the tile assembly, helping maintain long-term performance in heated floor installations. This vapor pressure equalization design reduces the risk of moisture-related stress beneath tiled surfaces. Prova Flex-Heat is easy to cut, handle, and install, and it is compatible with the installation of diverse tile types, including ceramic tile, porcelain tile, granite tile, marble tile, travertine tile, slate tile, limestone tile, sandstone tile, onyx tile, quartzite tile, mosaic tile, natural stone, and other common flooring materials. When seams, transitions, and penetrations are properly treated with compatible waterproofing accessories and thin-set mortar, the membrane supports waterproof floor assemblies suitable for wet areas such as bathrooms, kitchens, laundry rooms, and powder rooms; bathtub surrounds and shower areas; and other indoor spaces.

It performs well over concrete, plywood, OSB, cement backer board, and other approved subfloors. The membrane provides load distribution across the tile surface, helping support point loads and reducing stress on grout joints in heated floor applications. Prova Flex-Heat uncoupling membrane is ideal for use in residential and commercial installations, including bathroom floors, kitchen tile flooring, basement floors, entryways, and renovation projects over existing substrates. It is also suitable for living rooms, dining rooms, bedrooms, hallways, and foyers.

The system is suitable for professional installers and DIY home improvement projects alike, helping streamline installation while improving finished floor performance. For bonding the membrane to the substrate, polymer-modified thin-set mortar is typically recommended, while tile installation over the membrane is completed using appropriate thin-set mortar based on tile type and project requirements. As a premium radiant floor heating uncoupling membrane, Prova Flex-Heat delivers reliable uncoupling, crack isolation, vapor management, heating cable support, and long-term tile protection in a single integrated underlayment solution.
