Roofing System Overview
All membranes offered by Duro-Last are composed of a top and bottom layer of PVC film laminated to both sides of a high-strength, weft-inserted polyester reinforcement scrim. The PVC film is a proprietary thermoplastic formulation of resins, plasticizers, stabilizers, biocides, flame retardants and UV inhibitors.
Features offered by All Duro-Last Membranes
As the commercial roofing industry’s leader in PVC roofing, Duro-Last produces roofing membranes with a history of providing long-term durability and watertight protection.
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.
Custom Fabricated Accessories
Compatible with all thicknesses of Duro-Last membranes, custom fabricated accessories result in better first-time quality giving building owners peace of mind.
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.
Mechanically attached membranes are recyclable after their life on the rooftop.
PVC is lightweight, and Duro-Last membranes can often be installed over an existing roof without a tear-off.
PVC is a durable and serviceable product, meaning a Duro-Last roof can have a longer life than roofs made from other materials.
