KEE-Stone® Unreinforced Detail Roll

  • Robust Formulation
  • Flexibility
  • Chemical Resistance

KEE-Stone Unreinforced Detail Roll is a 60-mil, 24-inch wide unreinforced thermoplastic membrane enhanced with ELVALOY™ HP. This unique Ketone Ethylene Ester (KEE) formula creates a material with superior durability and flexibility. KEE-Stone Unreinforced Detail Roll is intended for field wrapping unusual shaped roof penetrations, flashing pipes, scuppers, inside/outside corners or other details where a pre-molded accessory is not an ideal use in the KEE-Stone membrane or flashing system.

Robust Formulation

The KEE-Stone thermoplastic compound contains at least 50 percent ELVALOY™ HP by polymer weight with no added liquid plasticizers, creating a membrane with superior long-term weatherability. KEE-Stone’s formula enhances the performance compared to standard PVC by making it flexible. Utilization of the KEE polymer as a solid plasticizer prevents plasticizer migration that is often seen in PVC membranes leading to a more stable and durable composition.

Flexibility

KEE-Stone’s KEE compound provides remarkable elongation and unmatched low-temperature flexibility in both warm and cold climates. Maintaining low-temperature flexibility down to -60°F (-51°C), KEE-Stone Unreinforced Detail Roll can withstand stresses while conforming to irregular surfaces and shapes, accommodating complex detailing.

Chemical Resistance

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, gases, greases, jet fuel, etc.
