Tremco ExoAir Trio - Impregnated Pre-Compressed Tape for Sealing Joints


Product Data Sheet


Product Description

ExoAir Trio is a UV-stable, pre-compressed, self-expanding, flexible joint seal. It is a polyurethane foam that is impregnated with a modified acrylic resin and treated with a pressure-sensitive adhesive on one side for ease of installation. ExoAir Trio also includes an additional layer acting as a vapor retarder. When installed, ExoAir Trio expands into the joint to create a seal that is airtight, thermally efficient and vapor permeable.

Basic Uses

ExoAir Trio is typically used as a perimeter seal around doors and windows, but can also be used in a variety of other joint applications that require a weathertight, vapor permeable, and thermally-efficient transition. ExoAir Trio can be installed onto vinyl, wood, concrete, aluminum, fiberglass, and other typical construction substrates.

Features and Benefits

ExoAir Trio has many advantages over conventional sealants:

  • Remains permanently flexible.
  • Low volatility.
  • Compatible with several Tremco Sealants.
  • Minimal surface preparation required.
  • Can be applied in various weather and temperature conditions.
  • Can be painted over with water-based, flexible paint.
  • Easy soap-and-water cleanup: no solvents, no cartridges, no pails.
  • Compatible with most porous or sensitive substrates.
  • ExoAir Trio has an adhesive strip on one side of the joint seal which keeps it in place while it expands to fill the joint.
