The adhesive is covered with a split release liner. SA-SBS Cap Sheet & SA-SBS Cap Sheet FR are finished with granules on the top surface and features SEALLap® ULTRA side lap with self-adhesive compound for an instant bond, tested stronger than all other application methods and FASTLap®, granule free end lap. Each of these patented features provide for greater ease of application as well as improved long-term performance. SA-SBS Cap Sheet & SA-SBS Cap Sheet FR are also used as a flashing membrane in all applicable specifications.
