IKO WCL (Water Control Layer) is used as a separating and water control layer in low moisture impact inverted and green roofs. It is used in combination with IKO XPS as part of the IKO WCL System for inverted and green roofs.

High performance, thermally bonded tri-laminate of polypropylene; spun bonded (outer layers) and microporous (inner layer). Water resistant properties result in reducing the flow of water through the roof construction, which means that the impact on thermal performance by rainwater cooling is largely negated. Inverted and green roofs incorporating IKO WCL are lighter as less ballast is required.

Key Benefits to your project

  • Improves the thermal performance of inverted and green roofs

  • Waterproof and water vapour permeable

  • Enables thinner insulation and less ballast to be used

  • BBA approved (Certificate No. 17/5467)
