Features offered by All Duro-Last Membranes

  • Superior Scrim

    Knitted in-house and with a density of either 18 x 14 or 18 x 9, the fabric is made from polyester threads that provide superior tear and puncture resistance and treated to prevent wicking.

    The highly reflective Duro-Last, Duro-Tuff, Duro-Last EV, Duro-Fleece and Duro-Fleece Plus white membranes are ENERGY STAR® qualified and provide energy savings in all climates.

    Multiple color options are available for many of the Duro-Last membranes.

  • Recyclability

    Mechanically attached membranes are recyclable after their life on the rooftop.

  • Lightweight

    PVC is lightweight, and Duro-Last membranes can often be installed over an existing roof without a tear-off.

  • Serviceability

    PVC is a durable and serviceable product, meaning a Duro-Last roof can have a longer life than roofs made from other materials.
