When it comes to tile installation, ensuring the longevity and integrity of your flooring is paramount. That’s where the PROVA FLEX-HEAT® Tile Underlayment comes into play. This innovative solution is designed to cater to both the functional and aesthetic needs of any tiling project, making it an essential component for both professionals and DIY enthusiasts.
What Sets PROVA FLEX-HEAT® Apart?
PROVA FLEX-HEAT is not just another underlayment; it’s a game-changer in the flooring accessories market. This lightweight uncoupling membrane is engineered with unique capabilities to accommodate heating cables, making it perfect for projects that require underfloor heating. The membrane features deep grooves with locking channels, suitable for multiple thicknesses of heating cables, ensuring versatile compatibility and ease of installation.

Patented Technology for Maximum Durability
The patented Shear Stress Control® system equipped with a non-woven anchoring fleece is what really sets PROVA FLEX-HEAT apart. This technology is designed to neutralize stress caused by movement in the substrate, providing a stable foundation that significantly extends the life of your tile flooring.

Optimal Heating Cable Compatibility and Efficiency
PROVA FLEX-HEAT supports multiple wire sizes of up to 0.2” (5 mm) thick, with the capability to achieve 3” (7.6 cm) cable spacing. This feature allows for the most efficient heat distribution as recommended by wire manufacturers, ensuring your space is heated evenly and effectively.

Versatility and Moisture Management
At 0.26″ (6.5 mm) thick, the membrane can also be used without heating cables, allowing for a level transition to match up to higher floors—perfect for renovation projects. Additionally, the innovative Vapor Management System features open-air channels beneath the fleece layer, providing a pathway for moisture to dissipate. This makes PROVA FLEX-HEAT exceptionally well-suited for below-grade installations where moisture management is crucial.

The PROVA FLEX-HEAT Tile Underlayment isn’t just about innovative features; it’s also about proven results. It has achieved an EXTRA HEAVY performance rating when tested according to ASTM C627 standards. For installation, premium polymer-modified thinset mortar is required to ensure optimal adherence and performance, emphasizing the product’s commitment to quality.
