ExoAir 110AT | Self-Adhered Vapor Barrier
ExoAir 110AT is a high-performance, primerless, self-adhered air and vapor barrier membrane designed for optimal protection in demanding building envelope applications. This innovative solution ensures uniform membrane thickness and long-lasting durability while offering a simplified installation process with no primer required. With 12-month UV resistance and NFPA 285 compliance, it meets the most rigorous commercial construction standards.
Product Description
Engineered to improve air tightness and moisture control, ExoAir 110AT combines peel-and-stick convenience with the ability to withstand extreme temperatures. It is ideal for use on exterior grade gypsum, plywood, concrete, and unpainted masonry. The membrane can be used as the primary vapor barrier or as part of a complete air barrier system. Thanks to its consistent membrane thickness, it delivers superior performance when compared to traditional fluid-applied membranes. Whether you’re facing hot summers or cold winters, this solution supports installation in all seasons and offers long-term reliability.
Key Benefits
- Uniform thickness across surfaces due to pre-manufactured sheet form
- 12-month UV resistance for jobsite flexibility and scheduling confidence
- Certified to NFPA 285 standards for fire resistance and code compliance
- Supports a wide range of service temperatures and climate zones
- Primerless peel-and-stick application reduces labor time and cost
- Performs in cold weather conditions—install at temperatures as low as 20 °F
Common Applications
- Exterior grade gypsum and plywood sheathing
- Concrete and unsealed masonry facades
- Metal substrates and façade systems
- Nudura® Insulated Concrete Forms (ICF)
Storage & Packaging
ExoAir 110AT is supplied in rolls and should be stored in a cool, dry area out of direct sunlight. Store flat to prevent deformation. Follow product datasheet guidelines for maximum shelf life and jobsite handling.
