AeroBarrier is an interior applied air sealing system that seals all building envelope leaks up to 1/2″.
The waterborne acrylic sealant is applied by pressuring a targeted building area, then spraying the aerosolized sealant into the pressurized space. The sealant is self-guided to the edges of visible and invisible leaks creating a seal not by packing the gap but by accumulating a crossed surface of leaks.
Designed to deposit in leaks and not on vertical surfaces, the sealant is applied within 60-90 minutes. It dries before system cleanup is complete, allowing construction to resume shortly after the process is complete with little to no impact on standard construction schedules.
The system measures the envelope leakage in real-time, enabling the system to dial-in specific requirements for air leakage and guarantee the results.
AeroBarrier may be applied at any time between rough-in and before occupancy. Although, the ideal time to apply AeroBarrier is rough-in or post-drywall. Other factors that affect installation are the build process and climate zone.
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, the area is safe to enter without protective gear within 20 to 30 minutes.
The AeroBarrier sealant is based on waterborne acrylic that has been used as a fluid-applied permeable air barrier for many years. 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, tensile strength, etc.
The sealant is low VOC and has no off-gassing.
The entire AeroBarrier process, from setup to completion, takes approximately 4-hours for a typical single-family home. Additional time may be required when targeting reduced envelope leakage levels of Passive House or ZERH.
The cost will depend on the construction phase and targeted air tightness levels.

AeroBarrier seals holes as large as ½” and as tiny as human hair. Aerosol sealing is extremely effective at sealing narrow gaps and small holes that are typically not cost-effective or are missed during manual sealing.
If AeroBarrier is applied at rough-in or right after drywall is installed, very minimal preparation is required. Vertical surfaces like walls and windows require no covering. All designed openings, such as ducts, electrical and plumbing, must be covered before sealing. All finished horizontal surfaces need to be covered.
The AeroBarrier process requires temperature control and pressurizing of the areas to be sealed. The ideal condition is an outdoor temperature of ≥ 40˚F. Sealing can be done below 40˚F but may require additional steps for the preparation.
Yes, the AeroBarrier sealant is GreenGuard Gold Certified, meaning that it’s safe to be used inside a home and meets the stricter certification requirements for use in schools and healthcare facilities.
How long after the sealing process can work resume in the space?
The area must be aired for 30 minutes after the sealing is complete. This is done by opening doors and windows while running the fan. But work can resume in the space as soon as the sealing equipment is removed and 30 minutes have passed.
The AeroBarrier system uses a standard 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.
AeroBarrier modifies its blower door by adding a heater onto the fan. This allows the system to achieve optimal room temperature and humidity during sealing, allowing more sealant to be sprayed into the space for a faster, more efficient sealing process.
How large of a space (square footage) can this be used?
AeroBarrier has been used in apartments as small as 500 sq ft and 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.
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 as tight as it is designed for. AeroBarrier can meet any IECC, Passive House, LEED, Well Standard, ENERGY STAR or Net Zero requirement.
A too-tight home can be bad 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 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 it is designed for.
