Air-Bloc® 17MR is a liquid-applied, elastomeric membrane designed to provide a vapor permeable air and water barrier when applied to above-grade wall assemblies. It is single component, water-based and cures to a tough monolithic rubber-like membrane, which resists air leakage and water penetration. Air-Bloc® 17MR includes antimicrobial technology to create an integral mold resistant membrane, and offers a broad application temperature range with proprietary fire resistance technology to achieve compliance.
