Fluid-Applied, Asphaltic Air & Vapor Barrier Membrane
ExoAir® 120 Fluid-Applied Air and Vapor Barrier Membrane is a monolithic, elastomeric membrane designed to seal exterior above-grade wall assemblies and mitigate air infiltration/exfiltration, vapor transmission and water penetration. It is available in two grades: ExoAir 120 SP (spray grade) and ExoAir 120 R (roller grade).
ExoAir 120 is typically applied to exterior sheathing panels, concrete block, poured concrete or wood substrates as an air and vapor barrier material. ExoAir 120 can be used with ExoAir 110, ExoAir 110AT, ExoAir 111 or Dymonic® 100 liquid flashing to detail into the rough opening.
