A single ply membrane is made up of three components. The top layer of the roofing membrane is what has to hold up to the elements, we call that the weathering layer. The next layer is the reinforcement or scrim layer. This is where you get your puncture resistance, tear/breaking strength and dimensional stability. The bottom layer helps sandwich in the middle fabric layer. Duro-Last® is committed to making the world's best single ply roofing membrane. Our top weathering layer is the thickest in the industry giving you the highest mils above scrim. Duro-Last® manufactures it's own polyester non-wicking scrim in a 14x 18 or 9x18 pattern. Giving you superior puncture resistance and performance.
Over the years TPO has been seen as being flexible and resistant to weather; therefore, being popular and viable choice contractors choose for commercial buildings. However, the Duro-Last® single-ply membrane, also known as PVC, is slightly more flexible in comparison to TPO and stronger seams to protect roofs from heavy use or extreme environments.
