ExoAir® 120
Brand: Tremco IncorporatedExoAir® 120 Fluid-Applied Air and Vapor Barrier Membrane is a monolithic, elastomeric membrane designed to seal exterior above-grade wall assemblies and mitigate air infiltration/exfiltration, vapor transmission and water penetration.
Features- ExoAir 120 is typically applied to exterior sheathing panels, concrete block, poured concrete or wood substrates as an air and vapor barrier material.
- ExoAir 120 can be used with ExoAir 110, ExoAir 110AT, ExoAir 111 or Dymonic® 100 liquid flashing to detail into the rough opening.
- EXOAIR 120 is a seamless, monolithic membrane that creates a fully adhered air and vapor 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 selfadhered membrane systems
- EXOAIR 120 can be co-sprayed to accelerate the curing process when weather threatens washout, or to fast-track construction
