AeroBarrier FAQs

The AeroBarrier sealant is based on a water-borne 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, anti fungal properties, tensile strength, etc.

The sealant is low VOC and has no off-gassing. See the Material Safety Data Sheet for more information.

AeroBarrier can be applied at any time after the space can be pressurized. Rough-in or early stages of drywall is the most economical for application, but it can be applied to completely finished spaces as well. Contact Us today to see when AeroBarrier should be applied on your project.

The entire AeroBarrier process, from setup to completion, takes approximately 6-hours for a typical single-family home. Application times may vary depending on the size of the building and how leaky it is. Additional time may be required when targeting reduced envelope leakage levels to meet Passive House requirements. Contact Us to see how we can save you time on your next project.

Cost will vary depending on size of the building, phase of construction and desired tightness levels. Once we receive your job specifications, we can give you a quote for your project. Contact Us today for a quote.

Third-party lab testing reveals AeroBarrier withstands a simulated 50-year durability test, with little or no seal degradation. See the durability testing report for the 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 rough-in or right after drywall is installed, there in very minimal preparation required. Vertical surfaces like walls and windows require no covering. All designed openings, such as ducts, electrical and plumbing, need to be covered prior to sealing. All finished horizontal surfaces need to be protected. Contact Us if your project has special circumstances.

The AeroBarrier process requires temperature control and pressurizing the areas to be sealed. The ideal temperature for application is an outdoor temperature of ≥ 40˚F. Sealing can be done below 40˚F but may require additional steps for the preparation. Contact Us if it will be below 40˚F at the time of installation to discuss the additional steps necessary for a successful installation.

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. Since AeroBarrier does not produce any off-gassing, work can resume in the space as soon as the 30 minutes is up and the sealing equipment has been removed by the technicians.

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.
