The Duro-Last Roofing System

The Duro-Last vinyl roof membrane is a proprietary thermoplastic formulation consisting of PVC resins, plasticizers, stabilizers, biocides, flame retardants and U.V. absorbents. A 14x18 threads per inch weft-insertion knitted scrim gives the membrane its strength and durability. The Duro-Last membrane is available in white, tan, gray, or dark gray.

Duro-Last has met or exceeded all major fire and wind code requirements, and regional approvals as necessary throughout the country. These certifications reinforce Duro-Last's leadership in providing the consistent, watertight integrity that building owners expect.

Duro-Last is proud to be a charter partner of the Energy Star® Roof Products Program. The Energy Star® label indicates to building owners and managers that the Duro-Last white vinyl roof membrane can save them money on cooling costs due to its high reflectivity (reflects 88% of the sun's energy). Duro-Last is also a charter member of the Cool Roof Rating Council (CRRC) and a member of the United States Green Building Council (USGBC).

Duro-Last participates in all major technical committees in the roofing industry, plus the American Society of Testing Materials (ASTM).
