Roofing System Overview

All membranes offered by Duro-Last are composed of a top and bottom layer of PVC film laminated to both sides of a high-strength, weft-inserted polyester reinforcement scrim. The PVC film is a proprietary thermoplastic formulation of resins, plasticizers, stabilizers, biocides, flame retardants and UV inhibitors.

    The highly reflective Duro-Last, Duro-Tuff, Duro-Last EV, Duro-Fleece and Duro-Fleece Plus white membranes are ENERGY STAR® qualified and provide energy savings in all climates.
