How Does it Work?
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 a crossed 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.
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.
What size leaks will this seal?
AeroBarrier seals holes as large as 1⁄2”, 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 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. Click here to see the durability test results.
Whatʼs 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.
Is the sealant safe to use inside the home?
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.
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.
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 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.
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.
How is Leakage Measured?
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.
