Tremco Commercial Sealants & Waterproofing has introduced ExoAir® 111, a high-performance, versatile, impermeable air and vapor barrier membrane that can be used in wall assemblies across a wide variety of climates and temperatures. This newest addition to Tremco’s comprehensive air barrier system offerings provides product stability at temperature extremes from 20 to 240 °F (-7 to 115 °C), reducing construction delays and eliminating the need for high or low temperature accessories. ExoAir® 111 is also UL certified for the NFPA 285 Standard Fire Test Method, simplifying the process for architects, consultants, and specifiers when determining International Building Code (IBC) compliance for fire propagation characteristics.
ExoAir® 111 is comprised of 20 mils of high-performance butyl laminated to a 4 mil metalized high-density polypropylene film and a siliconized release liner, creating a 24 mil composite sheet. Unlike traditional 40 mil systems, this product’s reduced material weight and primerless application minimize installer fatigue, increase productivity and accelerate construction schedules. This factory controlled mil thickness also ensures peace of mind because the application is consistent, with level coverage for quality assurance and protection. The metalized facer was engineered for low heat absorption, resulting in thermal stability during the construction cycle. The product’s superior UV resistance also allows prolonged exposure to the elements with no material degradation, and the rugged HDPP film protects high performance butyl membrane against incidental damage during the construction process.
ExoAir® 111 is designed for use as the membrane or as a component of an air barrier system. Documented, tested results have proven that it is chemically compatible with all asphalt based membranes in the ExoAir® product line as well as many high-performance Tremco sealants including Dymonic® 100 and Spectrem® 1. Specially formatted to meet job specific needs, ExoAir® 111 comes in a variety of sizes ranging from six to 36 inches.
