TREMCO EXOAIR 230 LIMESTONE 5GL

Tremco ExoAir 230 is a fluid-applied, synthetic, vapor-permeable air barrier designed for use in commercial construction projects

Tremco ExoAir 230 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.

Formulated to include UV resistance, providing the flexibility to install rain screen 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.

• EXOAIR 230 is a UV stable, seamless, monolithic membrane that creates a fully adhered air barrier when properly installed
• The ability to roller or spray apply the material affords the contractor the ability to accelerate installation times compared to traditional self-adhered membrane systems
• The high-performance properties of the EXOAIR 230 membrane retard the migration of air and bulk water but allow water vapor to pass through the membrane. As a result, vapor permeable systems like EXOAIR 230 allow for more flexibility in the placement of the air barrier membrane in the wall design
• EXOAIR 230 is formulated for UV resistance providing the flexibility to install rain screen systems with open joints or to allow the membrane to be exposed longer during the construction process
• EXOAIR 230 can be custom colored to meet all of your design needs
• EXOAIR 230 is specifically formulated for design options requiring assemblies that have been evaluated for NFPA 285
