FAQs

Western AeroBarrier services the west coast from the San Francisco Bay Area through to San Diego,  and easterly from Las Vegas down to Yuma.

AIR BARRIER AT EXTERIOR: AeroBarrier is installed right before insulating unless the insulation is to be spray foam, in which case it is best to install after spray foam.  AIR BARRIER AT DRYWALL:  AeroBarrier is installed at any stage between drywall taping and drywall priming.

AeroBarrier application is not appropriate for occupied residences/buildings.  We will only apply in new construction or in gut-remodels before any “finishes” are installed.

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.

The AeroBarrier sealant is based on 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, tensile strength, etc..

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. Schedule a time to speak with an AeroBarrier representative here. 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.
