ExoAir 220 is intended to secure buildings against airflow and leakage while enabling vapour materials to diffuse through and not become entombed within the wall

Condensation occurs within the wall cavity as a result of entombed humidity vapour, which can result in extensive degradation and truncated structure life. ExoAir Wind Barrier Systems also include ExoAir Liquid Wind & Insulating Properties Membrane for roller and dab implementation, the ExoAir Self-Sealant Wind & Moisture Barrier Ultrafiltration, the ExoAir TWF Self-Adhered Thru-Wall Flashing Outer layer, ExoAir Dismissal Latex caulk, and litigation application. With the incorporation of ExoAir 220 into the ExoAir Wind Barrier Systems, a testing ground for effectiveness, reliability, and ease of application has been established. A comprehensive, interoperable wind and vapour barrier system from a particular source with confidence. The US Environmental protection Agency forecasts that a comprehensive, efficient structure in order, energy efficiency can be enhanced by up to 40 percent of the overall while also continuing to improve comfort conditions.

EXOAIR 220 is a 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 selfadhered, membrane systems., The high-performance properties of the EXOAIR 220 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 220 allow for more flexibility in the placement of the air barrier, membrane in the wall design.
