Tarco Formulates a New Self-adhering Underlayment for Metal and Tile Roofing: PS200MU

Tarco, Little Rock, Ark., announced LeakBarrier PS200MU Ice and Water Armor, a self-adhesive, glass fiber reinforced, modified bituminous underlayment especially for metal roofing. It helps protect a building’s deck or internal structure against leaks caused by ice and water damming and wind-driven rain. PS200MU is specially formulated for use in high temperature environments. The upper side is made of a nonabrasive polyolefinic film that has anti-skid properties for good walkability. Two key attributes of a metal roofing underlayment are that it slides under the metal roof without scratching it; and that it is tolerant of high temperatures often reached beneath a metal roof. PS200MU offers both of these features. PS200MU is highly effective in critical roofing areas such as valleys, ridges, coping joints, chimneys, vents, dormers, skylights, and low-slope sections. While ideally suited for use under metal roofing, it is also an excellent choice as an underlayment for shingles, slate, and mechanically attached tiles. The polymer-modified asphalt gives excellent pliability and the film surface is UV resistant. An anti-skid treatment allows for good walkability. This underlayment is exceptionally durable with high tensile and tear strengths. Glass fiber reinforcement imparts high dimensional stability. It is a cost-effective sheet for clean, easy-to-handle, self-adhering applications. The split-back release film peels off for easy installation and handling and PS200MU adheres to a variety of substrates. The membrane lays flat and resists wrinkling for ease of application and a 60-day exposure allows for long term dry in. It provides instant watertight laps and self-seals around nails. The SBS-based membrane is specially formulated to provide high-temperature stability to 250 degrees Fahrenheit, making it ideal for use as an underlayment in metal roofing applications. The high temperature stability of the PS200MU membrane makes it especially attractive for residential and commercial metal roofing applications, although it is also suitable for shingle, slate and tile. Tarco’s family of LeakBarrier Ice and Water Armor membranes now includes three metal roofing underlayment products, including PS200MU, PS200HT and NR500HT. All three products withstand high temperatures and they are nonabrasive and provide good walkability. The main difference is upper surface: PS200MU uses polyolefin and PS200HT uses polyester, while NR500HT is a premium 40 mil (1 mm) thick, non-reinforced roofing underlayment with an upper surface of cross-laminated polyethylene-based Valeron film. PS200MU Meets ASTM D1970. It has Miami-Dade County Approval NOA No. 08-0804.10 and meets ICC-ES ESR-2116 as well as Florida Building Code FL 10450-R1. It is listed under the UL Prepared Roofing File No. 16744. It is not for use in adhesive (foam) set tile applications and it is not recommended for extreme high temperature environments such as under copper or zinc metal roofing. Each of the metal underlayment products is covered by a “Thirty Year Self Adhesive Metal and Tile Underlayment Material Warranty.” Coverage and conditions pertaining to coverage are detailed in the warranty, which is available on the Tarco Website. “Tarco now manufactures three distinct underlayment products suitable for metal roofing and other high temperature environments,” says Steve Ratcliff, President of Tarco. “That means more choices for roofing contractors. Metal roofing projects are not all the same and contractors have different preferences. Between PS200MU and PS200HT and NR500HT roofing contractors can find exactly the right features in a peel-and-stick underlayment for metal roofing applications. Tarco is pleased to be in a position to provide these premium SBS-based underlayments to this fast-growing segment of the roofing industry.” For more details, contact Tarco, One Information Way, Suite 225, Little Rock, AR 72202.
