Duro-Last® EV and EV Fleece KEE Roofing Membranes

Duro-Last® EV and EV Fleece KEE Roofing Membranes

Duro-Last EV Roofing System Overview

Duro-Last EV is a Ketone Ethylene Ester (KEE) containing membrane, offering the same UV resistance, reflectivity and enhanced chemical resistance for which Duro-Last is known. Utilizing Elvaloy™ from Dow, the Duro-Last EV roofing membrane is flexible and weldable in low temperatures and performs well in cold, harsh environments.

Duro-Last EV Fleece combines high-quality fleece material on the underside of the membrane with the proven performance of the Duro-Last EV roofing membrane. This results in an ideal product for use in adhered and mechanically fastened applications over a wide variety of substrates.
