ExoAir® 230 


Tremco. Inc.

ExoAir® 230 Fluid-Applied Vapor-Permeable, UV-Resistant Air Barrier Membrane is a fluid-applied synthetic vapor permeable air barrier designed for use in commercial construction applications. It can be either roller or trowel applied to common substrates. It may also be used as a liquid-applied window flashing, enabling the contractor to address both the membrane and window flashing with a single material. ExoAir 230 is used to stop unrestricted air infiltration and exfiltration through the building envelope. In addition, ExoAir 230 serves as a weather-resistive barrier keeping liquid water out while allowing water vapor to pass through. ExoAir 230 is formulated for UV resistance providing the flexibility to install rainscreen systems with open joints or to allow the membrane to be exposed during the construction process.
