AeroBarrier is revolutionizing energy efficiency. 

Let us show you how.




A certified AeroBarrier contractor will visit and analyze the needs for the upcoming project. The sealing service will then be scheduled.



Blocks are placed over air vents in order to pressurize the space. Our system will then be set up and connected to the space.



With the space now pressurized, the current air leakage will be measured giving a clear view of the project's starting point.



Aerosolized sealant is then released throughout the space or ductwork, filling all remaining leakage points.



With the space now sealed, a live report is generated contrasting both the original and finalized sealing results.



Whatever minimal cleanup is finished as the job has come to a close. The space is now sealed.

Our Process


  • How does it work?
    AeroBarrier is an interior applied air sealing system that seals building envelope leaks up to 1/2″. The waterborne sealant is aerosolized and injected into a pressurized home. The sealant is self-guided to the edges of visible and invisible leaks to create a seal by accumulating across the leak surface. The sealant is applied within 60-90 minutes and dries quickly, before system cleanup is complete. This ensures construction can resume shortly after the process is complete with little to no impact on standard construction schedules. The AeroBarrier system measures envelope leakage in real-time, enabling the system to dial-in specific air leakage requirements with precision and guarantee the results.
  • How long does it take to apply?
    The entire AeroBarrier process, from setup to completion, takes approximately four-hours for a typical single-family home. When targeting reduced envelope leakage levels of Passive House or ZERH, additional time may be required.
  • How long does the seal last?
    Third-party lab testing reveals AeroBarrier withstands a simulated 50-year durability test, with little or no seal degradation. Click here to see the durability test results.
  • Is your formula safe?
    Our formula is a water-soluble organic compound and is proven safe. The sealant is ultra-low VOC and because it is inert there is no chemical reaction needed to form a seal meaning there is no off-gassing. With more than 150,000 projects sealed to date, we’ve helped hospitals, surgery centers, schools, and public buildings make sure their air is clean, healthy and comfortable – and saved them energy and money in the process. In fact, our sealant is GreenGuard Gold Certified, meeting the stricter certification requirements used in schools and healthcare facilities.
  • How much does AeroBarrier cost?
    Cost depends on the construction phase and targeted air tightness levels. Once we have your job specifications, we provide a written quote within 24 hours.
  • What size leaks will this seal?
    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 to seal manually, or that are missed using manual sealing techniques.
  • How large of a space (square footage) can this be used on?
    AeroBarrier has been used in apartments as small as 500 sq ft and in homes over 10,000 sq ft. As long as the space can be pressurized, it can typically be sealed. Additional blower doors can be added to increase the pressure in larger spaces.
  • How tight can AeroBarrier actually seal a home?
    AeroBarrier has sealed houses to as low as 0.19 ACH50. But the value is in the system’s ability to allow builders to seal a home to as tight as it is designed for. AeroBarrier can meet any IECC, Passive House, LEED, Well Standard, ENERY STAR or Net Zero requirement.
  • How is leakage measured?
    The AeroBarrier system uses a modified blower door to measure envelope leakage during the process. The blower door is calibrated to meet ASTM Standard E779, E1554, CGSB-149.10-M86, EN 13829, ATTMA Technical Standard 1, NFPA 2001, RESNET and USACE.
  • I heard that too tight of a home is actually a bad thing.
    A home that is too tight can be a bad thing if the space isn’t designed for that level of tightness. The popular saying “build tight, ventilate right” applies here and works both ways. Building tight without proper ventilation could cause issues with indoor air quality (IAQ) in the space. On the flip side, a leaky home with proper ventilation could cause the mechanical system to not work as it is designed. Because AeroBarrier can dial in the desired tightness of the space it removes the guesswork and ensures that the home is only as tight as the space is designed for.
  • What would happen if the sealant were to attach to something undesired?
    AeroBarrier can be cleaned off surfaces. We recommend using a standard citrus based cleaner as soon as possible.
  • Is it safe to breathe during application?
    No. During application, if a technician has to enter the space while it is being sealed, they wear personal protective equipment (PPE). After the sealing is complete, the area is safe to enter without protective gear within 20 to 30 minutes.
  • How long after the sealing has been done can work resume in the space?
    The area needs to be aired out for 30 minutes after the sealing is complete. This is done by opening doors and windows while running the fan. During this time, the sealing equipment and coverings are removed.
  • Can AeroBarrier be used as a vapor barrier?
    No, the AeroBarrier sealant is considered vapor open, allowing water vapor to pass through the sealant. AeroBarrier is not a primary air or vapor barrier.
