Fluid-Applied, Asphaltic Air & Vapor Permeable Membrane
ExoAir® 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.
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, ExoAir 111 or Dymonic® 100 liquid flashing to detail into the rough opening.
