Suitable for use in all types of single-ply systems including mechanically attached, ballasted, and fully adhered. Guarantees are available up to 20 years when using EverGuard® PVC XK 80-mil Fleece-Back Membrane.1 The factory-applied polyester fleece provides additional protection to the membrane including no need for a slip sheet when re-covering over a variety of roofs and enhanced puncture resistance, especially in areas more prone to hail. The addition of KEE to replace plasticizers provides better weathering characteristics. Efficiency increases 2–3 times when installing fleece-back with Two-Part Canister Low Rise Foam Roofing Adhesive (compared to standard PVC adhesives). Those benefits along with heat-welded seams, a high reflectivity, and how simple it is to repair and install make it the right choice for your job.
