ExoAir 220
Brand: Tremco IncorporatedExoAir® 220 Fluid-Applied Permeable Air Barrier Membrane is a monolithic, elastomeric membrane designed to be rolled or sprayed onto exterior above-grade wall assemblies to mitigate air infiltration/exfiltration and water penetration while remaining permeable to the passage of water vapor.
Features- ExoAir 220 is typically applied to exterior sheathing panels, concrete block, poured concrete or wood substrates as an air and vapor barrier material.
- ExoAir 220 can be used with ExoAir 110, ExoAir 110AT or Dymonic® 100 liquid flashing to detail into the rough opening.
- EXOAIR 220 is a seamless, monolithic membrane that creates a fully adhered air barrier when properly installed
- The ability to roller or spray apply the material affords the contractor the ability to accelerate installation times compared to traditional self-adhered membrane systems.
- The high-performance properties of the EXOAIR 220 membrane retard the migration of air and bulk water but allow water vapor to pass through the membrane. As a result, vapor permeable systems like EXOAIR 220 allow for more flexibility in the placement of the air barrier membrane in the wall design.
