Door and Window Tape

Door & Window TapeLeakBarrier Door and Window Tape is a flexible rubberized asphalt membrane that self-adheres to most surfaces and self-seals around nails, staples and screws. It is reinforced with a continuous polymer film that resists stretching. LeakBarrier Door and Window Tape helps prevent water, air and moisture leaks. 


LeakBarrier Door and Window Tape is ideal for sealing around window and door penetrations, corner boards, wall tie-ins, sheathing panel seams, under masonry and stucco and other detail areas.

Features and Benefits

  • Highly effective weather resistant leak barrier
  • Stops air leakage, reducing energy costs for the homeowner
