AeroBarrier is a convenient, cost effective approach to seal homes in less than 3 hours and provides real time verification until the air-tightness requirement has been achieved.

We guarantee that your project will meet any IECC, ENERGY STAR or passive house requirements. You will never fail a blower door test!

Why AeroBarrier is the best option?

Measurable Results

As AeroBarrier is applied, the results are displayed in real time. 

Time Saving

The whole process from setting up, sealing and cleaning takes on average 3 hours. Once set up, the AeroBarrier machine takes over and manages the sealing process through completion.


Sealant achieves durability performance in 3 key areas: flexing, aging and compatibility in tests simulating 50 years of service.

Cost Effective

No more caulking needed to weatherize a space pre-drywall. Avoid sealing guesswork, and save on time, material, labor and mechanical load.

Path to Passive House

By incorporating a blower door, the AeroBarrier system is able to dial in your desired leakage.


GreenGuard Gold certified with Ultra-low VOC content and no off-gassing. Work can resume in the home within 30 minutes.
