ExoAir® 230/230LT
Brand: Tremco IncorporatedExoAir® 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.
Features- 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.
ExoAir 230
- 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 rainscreen 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
- ExoAir 230 is an approved Water Resistive Barrier when applied to Nudura Insulated Concrete Forms (ICF), or insulated concrete forms.
ExoAir 230LT
- ExoAir 230LT is a low temperature grade of ExoAir 230
- ExoAir 230LT has the same features and benefits as ExoAir 230 listed above
