ExoAir® 110AT
Brand: Tremco IncorporatedExoAir® 110AT is a 22-mil composite impermeable membrane that is comprised of 16 mils of butyl and 6 mils of HDPP facer. It can be used as the membrane, detailing accessory, as well as thru-wall flashing of an air barrier system. ExoAir 110AT when installed properly as a system will provide the requirements of an air barrier: air impermeable, continuity, structural integrity and durability.
Features- ExoAir 110AT is an impermeable, self-adhered sheet designed to be applied to exterior cavity walls in order to mitigate air infiltration/exfiltration, vapor transmission and water penetration.
- Typically applied to exterior sheathing boards and concrete block, ExoAir 110AT can also be applied to poured concrete, steel, wood based, Nudura Insulated Concrete Forms (ICF), and insulated concrete forms substrate, as well as serve as detailing or a transition membrane into window and door openings.
- The high-performance butyl has been tested and is compatible with the ExoAir product line
- Primerless application allows for faster installation time
- Manufactured to a preset, uniform thickness that provides consistent and uniform coverage
- Rugged HDPP film protects high-performance butylmembrane against incidental damage during construction process
- Variety of widths available for job specific needs
- White facer reduces heat absorption, resulting in thermal stability during construction cycle
- Material installation and service temperatures eliminate the need for low temperature or high temperature accessories
- Reduced material weight compared to traditional 40-mil systems reduces fatigue on installers and can increase productivity
