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.

Cool Zone Roofing System

In the commercial roofing industry, reflectivity and cool roofing has been the dominant discussion point for several years, and the Duro-Last Cool Zone roofing system has set the standard for single-ply roof reflectivity and the resulting energy savings. Now, terms like sustainability, cool roofs, and cool roofing are receiving a lot of attention, and once again, Duro-Last is setting the bar.

But what does sustainability and cool roofing really mean for building owners, facility managers, contractors, architects, and other specifiers? It means that the design, construction, maintenance, life-cycle impact, adaptive re-use, destruction, and recycling of roofing components must help meet the long-term environmental standards demanded by today's high-performance buildings.

To be considered "sustainable," a roofing system must meet the Five E's of high-performance roofing: Energy, Environment, Endurance, Economics, and Engineering. In each of these areas, the Duro-Last Cool Zone cool roofing system leads the commercial roofing industry.
