Prova Flex-Heat+ Tile Underlayment sold per SF for Heated Floors

Material is 3.24 ft wide (38.75" or 99 cm) and is SOLD BY SQUARE FOOT (SF). One SF of material will be approximately 38.75 inches x 3.7 inches. If you know how many linear feet you need, multiply by 3.24 and round up to nearest SF (e.g. 10 LF = 10 x 3.24 = 32.4 SF - order 33 SF) Knowing that the material is 3.24 feet wide, it is best to plan how many linear feet of material you need based on that dimension then calculate SF on length of material rather than the exact amount of SF in your workspace.

Additional Information

Prova_Flex-Heat_X-section

ProVa Flex_Heat+ is a 0.24" thick (height) polypropylene membrane factory bonded to a white one-ply non-woven fleece on the underside to maximize bonding to the subfloor.

ProVa-Flex is lightweight, flexible, bridges cracks, does not rot and is highly resistant to solutions containing salts, acids, and alkalis, as well as many organic solvents, alcohols and oils. It is highly impervious to steam. An installation can be completely waterproofed by applying 5, 7 or 10 inch WP band waterproof membrane over all joint seams and edges.

Prova Flex-Heat+ holds your choice of electric radiant floor heating wire and also provides the only necessary underlayment for ceramic tiles and natural stone - replacing other products like concrete board. This all-in-one solution greatly simplified installation while providing maximum performance. This underlayment provides "uncoupling" performance on all suitable substrates and water vapor pressure equalization to address possible moisture in the substrate below. Prova Flex-Heat+ offers flexibility for your installation requirements. It can be installed and then tiled later after it's dry or tile can be installed immediately after the underlayment and wire placement phases are completed.
