The AeroBarrier sealant is a 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, and tensile strength.
The sealant is low VOC and has no off-gassing.
The entire AeroBarrier process, from setup to completion, generally takes approximately 4-hours for a typical single-family home. When targeting reduced envelope leakage levels of Passive House or ZERH, additional time may be required.
Cost is variable and dependent upon several factors, including building size, the phase of construction for installation, how “leaky” the building is to start, and the targeted air tightness value. Once we determine your project specifications, we provide a quote. Note that costs very for AeroBarrier installations dependent upon where you are in the country. For an “expensive state” for materials, labor, and business operational costs, such as California, the cost of AeroBarrier installations is higher than in a state like Texas.
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.
AeroBarrier seals holes as large as ½”, 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.
If AeroBarrier is applied at insulation phase or at drywall phase, there in very minimal preparation required. Vertical surfaces like walls and windows require no covering. All designed openings, such as ducts, electrical and plumbing, will be covered prior to sealing. All finished horizontal surfaces will be covered.
The AeroBarrier process requires temperature control and pressurizing the areas to be sealed. Ideal conditions 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 not only safe to be used inside a home, but it meets the stricter certification requirements for use in schools and healthcare facilities as well.
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. But work can resume in the space as soon as the sealing equipment is removed and 30 min has passed.
The AeroBarrier system uses a standard blower door to measure envelope leakage during the process. The blower door calibrated to meet ASTM Standard E779, E1554, CGSB-149.10-M86, EN 13829, ATTMA Technical Standard 1, NFPA 2001, RESNET and USACE.
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 across the surface of leaks. Designed to deposit in leaks and not on vertical surfaces, the sealant is applied within 60-90 minutes and 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.
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.
AeroBarrier can meet whatever tightness requirements the space is designed to handle. The AeroBarrier technology provides real-time air tightness readings allowing air tightness 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.
