The Duro-Last roofing system membrane is a proprietary thermoplastic formulation consisting of resins and plasticizers, stabilizers, biocides, flame retardants and U.V. absorbents. A weft-insertion knitted scrim that is laminated between two layers of film gives the membrane its strength and durability. The Duro-Last membrane is available in white, tan or 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 membrane can save them money on cooling costs due to its high reflectivity (reflects over 86% 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).
Same High-Performance Material, but with a Shingle Pattern for a more aesthetically pleasing appearance on Low-Slope roofs than can be viewed from ground level.
