Tremco ExoAir 230 is a fluid-applied, synthetic air & vapor permeable membrane.
Ships Within 24-Hours, if in-stock.
Tremco ExoAir 230 Fluid-Applied Synthetic Permeable Air Barrier Membrane is a monolithic, elastomeric membrane designed to be roller or spray-applied onto exterior above-grade wall assemblies to mitigate air infiltration/exfiltration and water penetration while remaining permeable to the passage of water vapor. Can also be used as a liquid-applied flashing, enabling the contractor to address both the membrane and flashing needs with a single material.
Can be custom colored to match your design needs. UV stable, seamless, monolithic membrane that creates a fully adhered air barrier when properly installed. Two application options, roller or spray-applied, to accelerate the installation process. High performance properties of the membrane retards the migration of air and bulk water but allows water vapor to pass through the membrane. Formulated for UV resistance providing flexibility when installing rainscreen systems with open joints or to allow the membrane to be exposed longer during the construction process.
Typically applied to exterior sheathing panels, concrete block, poured concrete or wood substrates as an air and vapor barrier material. Can be used with ExoAir 110 and ExoAir 111 to transition into window and door openings.
