Securock® ExoAir® 430 pre-applied fluid-applied synthetic permeable air/water barrier membrane is a monolithic, elastomeric membrane that is applied in a factory setting eliminating the inconsistencies and weather impact that can occur when applied in the field. It is applied to the face of USG's Brand Ultralight Glass-Mat Sheathing panels for above-grade wall assemblies to mitigate air infiltration/exfiltration and water penetration while remaining permeable to the passage of water vapor.

The Securock ExoAir 430 System is a high-performance, energy efficient air and water barrier system comprised of the USG’s Securock Glass-Mat Sheathing, Tremco’s ExoAir 430 membrane, as well as system accessories. The system accessories contain sealants and transition products that provide a comprehensive air barrier system.
We recommend specifying the Securock ExoAir 430 System in Division 7 - fluid-applied air barriers - because the system utilizes a fluid air/water material applied to glass mat sheathing. The application takes place in a controlled environment as opposed to the field, providing a more consistent membrane application; this high-performance factory fluid-applied system will meet and/or exceed the building performance requirements.
½-inch and 5/8-inch thick gypsum sheathing differ in the core's chemistry. 5/8“ is known as fire rated and Type X in the industry. Type X designation has been tested by ASTM E 119/UL 263 guidelines. Fire rated walls are used in interior and exterior spaces for fire propagation.
The benefits of 1/2” thick gypsum sheathing are it is more cost effective, lighter to lift, easier to carry, and can be installed faster than 5/8-inch.
The Securock ExoAir 430 System is manufactured in a controlled factory environment. This provides consistent mil thickness, no membrane cure time or risk of washout. This System can reduce man-hours and safety risks, and overall improve the schedule efficiency. The approach maintains the performance qualities of a fluid applied system, while addressing the challenges faced when applying a fluid in the field.
