Tremco Exoair 230 Air Barrier per 5 Gallon Pail - Limestone

ExoAir 230 Fluid-Applied Synthetic Permeable Air Barrier Membrane is a monolithic, elastomeric membrane designed to be rolled or sprayed onto exterior above-grade wall assemblies to mitigate air infiltration/exfiltration and water penetration while remaining permeable to the passage of water vapor.

• 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 allows 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

Application

ExoAir 230 is typically applied to exterior sheathing panels, concrete block, poured concrete or wood substrates as an air and vapor barrier material. ExoAir 230 can be used with ExoAir 110, ExoAir 110AT, ExoAir 230 with mesh as fluid-applied flashing or Dymonic 100 liquid flashing to detail into the rough opening.
