How AeroBarrier Works

AeroBarrier is the only method to reach any level of air tightness, the first time, every time.

What Does An AeroBarrier Seal Look Like?

Whether its brick, plywood, OSB, lumber, drywall, metal or plastic in home or office space, AeroBarrier can seal it. Post seal pictures below show the dried Aero Barrier sealant plugging air leaks in various materials.

Our Four-Step Air Barrier Process


Prep and Setup

Prep the area by covering any openings that won’t be sealed. This includes taping or covering any designed openings or finished horizontal surfaces within the space. Spray station are then set up throughout the area to be air sealed.

The AeroBarrier Connect system is then set up. It includes a blower door, nozzle stations and hoses, a fan with lay-flat tubing, and the master control unit.


Pressurize and Apply

Using a blower door, the space is pressurized. After that, a computer controls the entire process including the temperature, pressure, humidity, and distribution of sealant within the space.


Seal and Monitor

With the AeroBarrier Connect system, you see results in real-time. You have complete control over your desired level of air-tightness and can achieve any level required. At the end of the process, a final blower door test is run to verify the air sealing results. AeroBarrier then provides a Certificate of Completion that shows pre and post leakage.


Clean Up

After the air sealing is complete, work can resume in the space within 30 minutes. At that time, clean-up of all equipment and removal of all tape and coverings can occur.

Half Inch Gap

Our air sealing system seals all building envelope leaks up to ½”, and as small as a human hair.


GreenGuard Gold certified, the sealant is self-guided to the edges of leaks creating a seal.
