215 sq. ft. Flexbone UI 720 ​​Uncoupling Membrane​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

Floating Uncoupling Membrane is a revolutionary, loose-laid floating system that provides 100% uncoupling. The membrane’s separation from the underlying substrate results in significant time and cost savings through minimal required substrate preparation. ARDEX UI 720 FLEXBONE has a unique bone-shaped pattern with GripLock Technology for the highest level of mortar-to-membrane bond strength. The membrane is constructed of a highly durable, flexible plastic and a laminated, topside glass fiber mesh that contains self-sticking overlaps for easy seam connection. The membrane also contains more than 1,000 perforations per square foot for improved vapor pressure equalization.
