Frequently Asked Questions

At what stage of construction is AeroBarrrier applied?

AeroBarrier may be applied at any time between rough-in and prior to occupancy. Although, the ideal time to apply AeroBarrier is rough-in or post-drywall. Other factors that effect install is build process and climate zone.

Is it safe to breathe during application?

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.

What’s in the stuff being sprayed?

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.

How long does it take to apply?

The entire AeroBarrier process, from setup to completion, 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.

How much does AeroBarrier cost?

Cost will depend on the construction phase and targeted air tightness levels. Once we have your job specifications, we provide a written quote within 24 hours. Call us at 385.243.0395 or email us at [email protected] to talk about your project.

What is the lifecycle of the product, or how long does the tight seal last?

Third-party lab testing reveals AeroBarrier withstands a simulated 50-year durability test, with little or no seal degradation.

What size leaks will this seal?

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.

What surfaces need to be protected?

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 covered.

Can the sealing be performed in cold weather?

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.

Is the sealant safe to use inside the home?

Yes, the AeroBarrier sealant is GreenGuard Gold Certified, meaning that it is both safe to be used inside a home, and also meets the stricter certification requirements for use in schools and healthcare facilities as well.

How long after the sealing process can work resume in the space?

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.

How is Leakage Measured?

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.
