EXOAIR 230 LIMESTONE - 5 GAL

ExoAir® 230 is a fluid-applied, synthetic, vapor-permeable air barrier designed for use in commercial construction application. It is formulated to include UV resistance, providing the flexibility to install rainscreen systems with open joints or to allow the membrane to be exposed during the construction process. It also withstands temperatures up to 240°F (115°C) and ASTM E 84 testing for flame spread and smoke development shows it contributes to life safety issues. To provide further assurance of protection, Tremco has gone beyond traditional manufacturer testing and has also done testing on other components ExoAir 230 may be connected to, including Proglaze® ETA connections and sealants. ExoAir 230 is available in a single grade which can be either roller- or spray-applied to common substrates. When used with other ExoAir components including ExoAir 110 Self-Adhered Air & Vapor Membrane, ExoAir TWF (Thru-Wall Flashing) Membrane, ExoAir Primer, Spectrem® 1, Tremflex® 834, Dymeric® 240FC or Proglaze ETA Connections as a comprehensive system, continuity and long-term performance is assured.

• Is used to stop unrestricted air infiltration and exfiltration through the building envelope.
• 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.
• Serves as a weather-resistive barrier, keeping liquid water out while allowing water vapor to pass through to avoid trapping moisture within the wall.
