  • Excellent tear resistance – Resists cracking and breaking during installation
  • Self-adhesive – Adheres to the roof deck and creates a watertight seal around nails to help prevent water migration. Split backer sheet for easy application and positioning on the roof deck
  • Granulated surface – Provides a slip-resistant surface for excellent traction and safe installation
  • Taped selvedge edge – Improves seal between courses
