KEE-Stone Utility Roll is a 60-mil, six-inch wide, unreinforced thermoplastic membrane enhanced with Dow ELVALOY™ HP. This unique Ketone Ethylene Ester (KEE) formula creates a material with superior flexibility. The backside of the roll is smooth for easy heat welding installation for field detailing of penetrations. KEE-Stone Utility Roll is designed as the stripping ply to cover a seam in the KEE-Stone Flashing system and KEE-Stone membrane system. It can also be used to field wrap unusual penetrations where a pre-molded accessory will not work.
