Modified Bitumen Systems
Composite membranes consisting of bitumen, modifiers, and a reinforcement such as fiberglass or polyester. The modifiers provide a tough, rubbery property to the product and add flexibility. Modified bitumen sheets are manufactured in a consistent, controlled environment and are generally coated or covered with mineral granules. Modified bitumen systems are more flexible than BUR systems, yet share many of the advantages, including good resistance to roof traffic.
