ExoAir 120 Fluid-Applied Air & Vapor Membrane is a monolithic, elastomeric membrane designed to seal exterior above-grade wall assemblies and prevent 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 a seamless, fully adhered air and vapor membrane that creates an airtight membrane within the building envelope. The ability to either spray or roll apply the material affords the installer the flexibility needed to accommodate the specific needs of a project.
