Not all air barriers are the same. The Securock® ExoAir® 430 system is the only one that secures your building envelope and your reputation.
Bring two proven technologies to your job in one step.
The Securock® ExoAir® 430 system combines two trusted products, USG Securock® Brand UltraLight Glass-Mat Sheathing and a factory-applied Tremco ExoAir® fluid air/water barrier membrane. This wraps your building’s exterior in an innovative barrier and shields you from setbacks, headaches, and unexpected costs.
Two products you've used for years are now together as one complete system.
Up to 40% reduction in air barrier installation* enables greater speed and efficiency on the job site schedule.
With a factory-applied air barrier membrane, there is no waiting on the membrane to cure and the risk of washouts is eliminated.
Dry-in faster to allow interior trades to start working sooner.
Eliminate field application inconsistencies with a factory-applied membrane that is consistent in both thickness and performance.
Comprised of two products you’ve used for years, now together as one complete system.
The finished system provides the specified control of air and water throughout the entire building envelope.
The factory-applied membrane delivers confidence in knowing you have a consistent, high-performing barrier on every project.
This system offers ease of installation and enables greater speed and efficiency on the job site.
The membrane is extremely durable, allowing it to handle the rigors of construction, and then last a lifetime.
