The Duro-Last Single-Ply Roof Membrane  Duro-Last

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 a variety of colors.Duro-Last logo

Duro-Last Cool Zone

In these days of everything being promoted as "green," often without much substance behind the claims, Duro-Last® wants to get back to basics - at least with respect to roofing systems.

For Duro-Last, "white" refers to the bright white Cool Zone® roofing membrane. It has an initial reflectivity of 87.5%, based on ENERGY STAR testing procedures. Reflectivity is the percentage of the sun's energy that is reflected by a surface. Another important measurement of membrane performance is emittance - the percentage of absorbed energy that a material can radiate away. The Cool Zone system's total emittance is measured at 95%.

These attributes have given the Cool Zone system an established history of providing energy-saving benefits for commercial, institutional and industrial buildings throughout North America.
