The Duro-Last Single-Ply Roof Membrane
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 weft-insertion knitted scrim that is laminated between two layers of PVC film gives the membrane its strength and durability. The Duro-Last single-ply membrane is available in white, gray, dark gray, tan, or terra cotta.
Our flexible roof membrane is easily prefabricated into deck sheets up to 2,500 square feet in size, as well as custom-made parapet, stack, and curb flashings that eliminate most labor from critical roof areas – transitions and changes of plane. Prefabrication provides architects, specifiers, consultants, contractors, and building owners peace-of-mind regarding the watertight security of the roof installation.
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 has been approved by Factory Mutual as a 1-60,1-75, 1-90, 1-95, 1-105, 1-135, 1-150, 1-165, 1-195, 1-210, 1-270, 1-435, and 1-495 roofing system. Duro-Last is also listed by Underwriters Laboratories as a Class A, B, & C approved material. Evaluation services ICBO and NES have merged to form ICC-ES, which has evaluated Duro-Last for the International Building Code (IBC). The Duro-Last roofing system has been approved by the IBC and by code agency MIAMI-DADE for use in their respective jurisdictions.
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).
