Tarco’s LeakBarrier PS200MU Ice and Water Armor is a self-adhesive, glass fiber reinforced, modified, bituminous underlayment designed specifically for metal roofing. Formulated for use in high-temperature environments up to 250 degrees Fahrenheit, the PS200MU’s nonabrasive polyolefinic and UV-resistant film has anti-skid properties for walkability, and slides under a metal roof without scratching it. A split-back release film peels off, allowing the underlayment to adhere to a variety of substrates. Its membrane lays flat and resists, while Polymer-modified asphalt provides pliability. The LeakBarrier PS200MU meets ASTM D 1970, ICC-ES ESR-2116, and Florida Building Code FL 10450-R1, and has Miami-Date County Approval NOA No. 08-0804.10. tarcoroofing.com; 800-365-4506.
