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.

Durable

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.
