It is installed as a floating membrane over the underlying subfloor, protecting the tiles above from damaging developments such as lateral movement, shifts and in-plane substrate movement. Because of its truly uncoupling properties, this membrane can be safely laid over more difficult substrate types with reduced surface preparation requirements, saving time. Its perforations allow vapor pressure to equalize, which is a crucial factor for basement renovation when dealing with moisture-prone concrete slabs or wood-based subfloors.\u003c\/p\u003e\n\u003cp\u003eThe unique bone-shaped stud pattern on the surface of the membrane is easily filled with thin-set mortar, and the undercuts on each stud mechanically lock into the cured mortar as it dries, improving mechanical anchoring and overall grip to the tile covering. The studs support and protect tiles above while improving flexibility and absorbing shear movement. This improves tile and grout joint longevity. It's integrated self-sticking fiberglass mesh with self-sticking overlaps makes connecting separate sheets of this membrane faster and more consistent.\u003c\/p\u003e\n\u003cp\u003eARDEX UI 720 is designed for ceramic tile and stone floor installations over challenging substrates, such as existing tile, sound but cracked surfaces, painted floors and mixed substrates. It is a durable uncoupling membrane with crack-isolating benefits for tile installations, protecting your floor tiles by preventing potential damage and reducing grout stress from the substrate below. Works with a wide variety of tile and stone floor coverings, including ceramic tile, porcelain tiles, cement tiles, marble tiles, natural stone tiles and granite, when installed in accordance with manufacturer guidelines.\u003c\/p\u003e\n\u003cp\u003eMeets your home improvement needs whether you're installing bathroom tile (bathroom flooring), interior floor tile, or building a floor for your bedroom, hallway, interior living spaces, basement, kitchen, dining room, foyer or living area. The UI720 is particularly well suited for offices, hotel rooms, multi-unit housing, retail boutiques, film sets and showrooms, where floating tile installations may be preferred due to the potential need for future floor changes.\u003c\/p\u003e\n\u003cp\u003eARDEX UI 720 FLEXBONE is designed as a professional-grade floating uncoupling membrane system that eliminates the need for mechanical fastening or full-surface bonding to the substrate, making installation faster and cleaner compared to traditional underlayment systems. The membrane’s lightweight and flexible construction allows it to be easily cut and fitted around obstacles, drains, doorways, and irregular room layouts, making it ideal for both residential and commercial flooring projects. Its floating design helps accommodate substrate moisture migration and seasonal expansion and contraction, making it especially effective for slab-on-grade floors, basements, and renovation projects where moisture management is critical.\u003c\/p\u003e\n\u003cp\u003eARDEX UI 720 is compatible with standard thin-set mortars and premium polymer-modified mortars, allowing installers to achieve a strong mechanical bond between the tile assembly and the uncoupling membrane. The integrated glass fiber mesh enhances mortar adhesion and helps maintain dimensional stability during installation. This uncoupling floor membrane is engineered to reduce stress transfer from the substrate to the tile surface, minimizing the risk of tile cracking, delamination, and grout failure over time.\u003c\/p\u003e\n\u003cp\u003eIdeal for both residential and commercial applications, ARDEX UI 720 FLEXBONE supports long-lasting tile installations in high-traffic environments while offering flexibility for future floor changes or renovations. Its floating installation method allows tiles to be removed and replaced more easily than fully bonded systems, making it a practical choice for remodels, tenant improvements, and temporary flooring installations. Designed and manufactured to meet high European quality standards, ARDEX UI 720 delivers reliable uncoupling performance, crack isolation, and moisture vapor management for modern tile flooring systems.
