Overview

Air Sealing & Seam Tape is a single-faced adhesive tape of synthetic fabric backing which is coated by synthetic resin pressure-sensitive adhesive (PSA). It shows excellent effect for fixing of vapor barrier to create a continuous air barrier and reduces moisture intrusion and accumulation into the wall system. Since the bordering of white synthetic fabric is straight and hand-tearable, the workability is superior.

Thickness: 6.7mil (0.17mm)

Advantages

Excellent Air-tightness

  By using high performance adhesive, excellent air-tightness is achieved.

Excellent Workability

  The construction time can be reduced due to be rewound smoothly and hand-tearable.

Eco-friendly Products

  Since there is no release paper, on-site waste can be significantly reduced.

Application Examples

  • Joint tape for vapor barrier/retarder

Certification

  • Comply with the 2021 IECC of air permeance

Warning

  1. This product is a tape for an airtight sheet joint. Do not use it for any other purpose (such as waterproofing or fixing heavy products).
  2. Do not use this on PVC products (PVC materials) and human bodies (skin).
  3. This should not be used for electrical insulation.
  4. Please keep in mind that when the tape is applied and then peeled, this will leave an adhesive residue.
  5. Warm the tape before using it because at low temperatures, it becomes difficult to stick.
  6. Remove all dirt, dust, oil, and moisture from the surface before using the tape.
  7. Firmly press the tape to obtain the maximum adhesive strength.
  8. Store the tape in a cool location avoiding direct sunlight, any heat source such as heating apparatus, water leakage, and high temperature and humidity.
