Flexible System

Increased flexibility for added performance

Fibrelast has been engineered with FibreFlex technology, to increase the flexibility of the resin system without the need for any additional additives which often affects the natural rheology of the resin system. Additional flexibility will help the system deal with any thermal expansion and contraction as the roofing surface heats up and cools down throughout the day.
