AeroBarrier is an interior applied, computer controlled air sealing system. The sealant is applied by pressurizing a targeted building area, then spraying the aerosolized sealant into the pressurized space. The sealant is applied within 60-90 minutes and dries before system cleanup is complete. This allows construction to resume shortly after the process is complete with little to no impact on standard construction schedules.
No more caulking is needed to weatherize a space pre-drywall. Builders can avoid sealing guesswork, save on time, material and labor.
The AeroBarrier system uses a standard, single-point blower door test to measure envelope leakage throughout the process. The sealant is self-guided to the edges of visible and invisible leaks creating a seal, and accumulating across the surface of leaks.
AeroBarrier can meet whatever tightness requirements the space is designed to handle and guarantee the results. The AeroBarrier technology provides real-time air tightness readings allowing air tightness levels to be specified and achieved every time. AeroBarrier can seal houses just tight enough to meet any IECC code requirement or it can seal to levels below the Passive House standard of 0.6 ACH50.
AeroBarrier seals holes as large as 1/2", and as tiny as a human hair. Aerosol sealing is extremely effective at sealing narrow gaps and extremely small holes that are typically not cost effective or are missed during manual sealing.
The AeroBarrier X1 sealant is a waterborne acrylic. The sealant is GreenGuard Gold certified and has been tested according to various ASTM standards and NFPA 285, for fire spread, smoke production, adhesion, antifungal properties, and tensile strength. The sealant is ultra-low VOC and has no off-gassing. Work can resume in the home within 30 minutes of cleanup.
Sealant achieves durability performance in 3 key areas: flexing, aging and compatibility in tests simulating 50 years of service.

"AeroBarrier could very well be the end game in our industry's search for a comprehensive, cost-effective way to control leaks through building enclosures. Properly sealing a home or building to precise levels can be time consuming, stressful to site staff and expensive. With ever increasing expectations of homeowners and changing building codes, homes will be expected to be more air tight than ever. There isn't a more important technology in our industry today."

"AeroBarrier may be the most important innovation to hit the building community in years. We were seeking a tighter building envelope and AeroBarrier answered the call. The technology is easily deployable in the field, delivers results immediately which is invaluable, and works well in a fast paced production environment. You may be able to overcome the inefficiencies of manual sealing by repeating the process over and over, but it would require more expensive labor hours and still no guarantee. AeroBarrier is fast and you know the results before you are even finished."
Geoff Ferrell - Chief Technology Officer
"It was blowing people's minds - mostly because monitoring compartmentalization in a multi-family building under construction is typically a very difficult, time consuming task. The level of coordination and commitment you need to get from all contractors on the job is critical as it is nearly impossible to achieve. With AeroBarrier, it's simply not a problem."

The space needs to be aired out for 30 minutes after sealing. This is done by opening windows and running the fan. Work in the space can continue as soon as the sealing equipment is removed.
Although the sealing equipment can heat the air as it seals, there are practical limits to aerosol sealing when it comes to weather conditions. Ideal outdoor temperature is 40 degrees F or higher. Sealing can be done below this temperature, but additional steps may be required.
AeroBarrier can be applied at any time after the space can be pressurized. Different construction methods and climate zones will determine the proper time to apply AeroBarrier. Rough-in or early stages of drywall is the most economical for application, but it can be applied to completely finished spaces.
A team of UC Davis building scientists dedicated 5 years to research and development, determined to make envelope sealing quick, easy, and affordable.
If AeroBarrier is applied at rough-in or right after drywall is installed, there is very minimal preparation required. Vertical surfaces like walls and windows do not need to be covered. All designed openings such as ducts, vents, electrical and plumbing penetrations, need to be covered prior to sealing. All finished horizontal surfaces need to be covered.
Application time depends on what the target ACH is for the house. Typical applications take between 90 and 120 minutes.
