ARDEX FLEXBONE Heat in-Floor Heating Waterproofing & Uncoupling 1/4" Membrane 134.5 Sq Ft Roll UH 900 (9 Rolls Bundle)

ARDEX FLEXBONE HEAT is the ideal membrane underlayment for installing in-floor heating cables. It provides uncoupling and waterproofing capabilities, including crack suppression, load distribution, and vapor management. It also features minimal roll memory - if unrolled, it will lay flat (doesn't curl). ARDEX s dependable German engineering promises efficiency, durability, ease of use, and high performance for any home improvement project. The crossbone stud pattern on the heat membrane was designed for the fast and easy installation of an electrical heating cable, providing additional benefits. The pattern allows for one-pass thinset mortar adhesive to cover the heat cables entirely, speeding up heated floor installation. It creates fewer touchpoints between the heating wire and membrane, improving uniform heat distribution and eliminating cold spots. It leaves less air space within the mat structure for faster and more efficient heating of the floor surface above. The extra large uncoupling width offers a seamless transition with hardwood and other raised flooring. It makes this membrane great for living areas that require infloor heating, such as - closed balconies, food courts, lobbies, hallways, foyers, living and dining rooms, basements, and garages. It is a durable crack-isolating and uncoupling membrane, protecting your floor tiles (tile coverings) and other surfaces by preventing potential damage and reducing grout stress from the substrate below. Works with various surfaces - linoleum tiles, vinyl flooring, ceramic tiles, porcelain tiles, cement tiles, marble tiles, natural stone tiles, granite, concrete blocks, and carpet tiles. It's a robust waterproofing membrane that makes it usable in your shower, bathroom, hot tub and bathtub surround, kitchen, laundry room, and other wet areas where potential water leakage is a concern—a perfect solution for any DIY or professional projects. Ideal for large format tile and thin porcelain tile installations.
