Prep the space. This includes taping or covering any areas that won’t be sealed. Emitters are then set up throughout the area to be sealed.


Pressurize the space with the use of a blower door. A computer does the rest, including the control of temperature, pressure, humidity, and distribution of sealant during the process.


See the results in real-time. Throughout the application process, the computer monitor displays the ACH improvement, allowing you full control over your desired level of envelope tightness and the leakage reduction.


Run a final blower door test to verify the sealing results. At the end of the process, receive an AeroBarrier Certificate, with a pre and post leakage report.
