105 Flashing

105 Flashing Membrane is a 105 mil, strong, pliable self-adhesive sheet consisting of high density polyethylene film bonded to a layer of rubberized asphalt waterproofing compound with slit release sheet to conform to 90″ angles. 105 Flashing is used in exterior flashing applications to deflect water. Applications include spandrel beams, sills, copings, door and window headers, and flange flashings.


  • Can be field fabricated to meet various job site conditions without cracking as compared to some metal systems
  • High puncture resistance provides protection against abuse by other trades during and after installation
  • Rubberized asphalt membrane adheres tenaciously to the surface and itself eliminating blow-off and tears, before exterior wall installation
  • Rubberized asphalt used in this flashing will help to self-seal if the membrane is punctured
