ARDEX UI 720 Flexbone

Floating Uncoupling System


ARDEX UI 720 FLEXBONE Floating Uncoupling System is a revolutionary, loose-laid floating system that provides 100% uncoupling. The system’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 adhesive-to-sheet bond strength. The sheet is constructed of a highly durable, flexible plastic and a laminated, topside glass fibre mesh that contains self-sticking overlaps for easy seam connection. Residual moisture in the substrate is distributed evenly through a system of channels with more than 10,000 perforations per square metre. These channels allow moisture to discharge via the perforations and covering joints. For internal applications only.
