Air Sealing and Flashing Tape is a single-adhesive tape that makes airtight and waterproof for the sheathing joint. It is usable for all seasons since it can keep stable adhesive property in wide range of temperature by the characteristics of butyl adhesive. And, the workability is superior because it is hand-tearable, and without release liner.

Performance Characteristics

Air Sealing Performance

Test Method

  1. Prepare SPF with slit, then attached the Air Sealing & Flashing Tape to SPF
  2. Stick SPF to the chamber using caulking to avoid leaks.
  3. Air flows from the inlet, and the flow rate is measured on the outlet side.
  4. Air Sealing Performance is calculated by the following formula.
    Air Sealing Performance (%) = Outlet Flow Rate(ml/min) / Inlet Flow Rate(ml/min) *100

Test Result 100%
