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 50-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. 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.
