Frequently Asked Questions

AeroBarrier Arizona services all counties in Arizona. Contact us and we'll confirm service for your specific location — and if we don't service your area, we'll connect you with someone who does.

Air Barrier at Exterior: AeroBarrier is installed right before insulating, unless the insulation is spray foam — in which case it is best installed after spray foam.

Air Barrier at Drywall: AeroBarrier is installed at any stage between drywall taping and drywall priming.

No. AeroBarrier is not appropriate for occupied residences or buildings. We only apply in new construction or gut-remodels before any finishes are installed.

No. Technicians entering the space during application wear personal protective equipment (PPE). After sealing is complete, the area is safe to enter without protective gear within 20 to 30 minutes.

The AeroBarrier sealant is a water-borne acrylic that has been used as a fluid-applied permeable air barrier for years. It is GREENGUARD Gold certified, low VOC with no off-gassing, and has been tested to ASTM standards for fire spread, smoke production, adhesion, antifungal properties, and tensile strength. It is also non-flammable and Red List Free.

The entire process — from setup to completion — generally takes about 4 hours for a typical single-family home. Targeting reduced leakage levels such as Passive House or Zero Energy Ready may require additional time.

Cost varies based on building size, the phase of construction at install, how leaky the building is initially, and your target air tightness value. Once we understand your project specs, we provide a quote. Contact us to get started.

Third-party lab testing shows AeroBarrier withstands a simulated 50-year durability test with little or no seal degradation. See the full durability test results (PDF).

AeroBarrier seals holes as large as ½ inch and as tiny as a human hair. It is especially effective at sealing narrow gaps and extremely small holes that are typically not cost-effective or are missed entirely during manual sealing.

Preparation is minimal. Vertical surfaces like walls and windows need no covering. All designed openings — ducts, electrical, and plumbing — are covered prior to sealing. All finished horizontal surfaces will be covered.

Ideal conditions are an outdoor temperature of 40°F or above. Sealing can be done below 40°F but may require additional preparation steps.

Yes. The sealant is GREENGUARD Gold certified — meeting the strictest certification requirements for use in schools and healthcare facilities, not just homes.

Open doors and windows to air out the space for 30 minutes while running a fan. Work can resume as soon as the sealing equipment is removed and those 30 minutes have passed.

AeroBarrier uses a standard 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. The space is pressurized with a blower door, then the aerosolized sealant is sprayed in. The sealant is self-guided to the edges of every leak — visible and invisible — accumulating across gap surfaces until sealed. It does not deposit on vertical surfaces. The computer monitors envelope leakage in real time and stops when your target is reached. The sealant is applied within 60–90 minutes and dries before cleanup is complete, so construction can resume with little to no schedule impact.
