IKO enertherm WCL (Water Control Layer) is a high-performance, thermally bonded tri-laminate of polypropylene. It has spun bonded outer layers and a microporous inner layer.
It is used as a Water Flow Reducing Layer (WFRL) between IKO enertherm XPS insulation boards and the roof ballast layer in inverted roof systems, including green, bio-diverse, and blue roof applications.
IKO enertherm WCL’s water-resistant properties result in reducing the flow of water through the roof construction. This means that the impact on thermal performance by rainwater cooling is virtually negated.
