KEE-Stone Utility Roll is a 60-mil, six-inch wide, reinforced thermoplastic membrane enhanced with Dow ELVALOY™ HP. This unique Ketone Ethylene Ester (KEE) formula creates a material with superior flexibility. KEE-Stone Reinforced Utility Roll features a dual-sided membrane—bright white on one side and medium gray on the other—giving you the flexibility to choose the best surface for your project. 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.

KEE-Stone’s unique KEE and Elvaloy™ HP formula enhances the performance of standard PVC by making it permanently flexible and locking in the oils to prevent the material from drying out and cracking.
KEE-Stone’s unique KEE compound provides remarkable elongation and unmatched low-temperature flexibility in warm and cold climates. Maintaining low-temperature flexibility down to -40°F (-40°C), KEE-Stone Utility Roll can withstand even the harshest stresses associated with thermal shock and adjust to those stresses without cracking, splitting, or crazing.
The strength of the KEE-Stone formula provides extensive chemical resistance properties even in the presence of common rooftop culprits like animal fats, acids, oils, greases, etc.
