Duro-Last® Roofing System

The Duro-Last roofing system is a proprietary thermoplastic formulation consisting of resins and plasticizers, stabilizers, biocides, flame retardants, and U.V. absorbents. A weft-insertion knitted scrim is laminated between two layers of film, giving the membrane its strength and durability. The Duro-Last® membrane is available in white, tan or gray.  The installed 40 mil system weighs .25 lbs. per square foot.
