Salt Shed Roof Material.pdf

This technical data sheet from Intertape Polymer Group details specifications for NovaShield II with ArmorKote RU88X-6, 4mil (400), which appears to be under consideration for the Lancaster County, South Carolina Kershaw Salt Shed Roof Replacement project. The document outlines the product as a heavyweight fabric designed for membrane structures and alternate daily landfill covers, featuring a special weaving pattern and proprietary coating to enhance thickness, flatness, abrasion resistance, and tear properties. The material is a woven clear HDPE scrim with 4 mil coating on each side, available in natural (clear), white, green, blue, beige, or red colors, with rolls available in 4-inch or 5-inch I.D. cores and widths up to 150 inches.

The technical specifications include detailed performance properties based on ASTM standard tests, including a thickness of 23 mil (0.59 mm), grab tensile strength of Warp 370 lb/Weft 345 lb, and strip tensile strength of Warp 245 lb/in/Weft 235 lb/in. The material demonstrates high durability with >90% strength retention after 2000 hours of accelerated UV weathering and >80% strength retention after 5 Florida Standard Years. The product meets ASTM E84-00a Class 1 fire testing requirements, though it is not flame retardant, and can withstand low temperatures down to -60°C.
