AeroBarrier ELITE Dealer

The Leader in AeroBarrier on the East Coast. Results Guaranteed.

Watch AeroBarrier in Action:

AeroBarrier is the only method to reach any level of air tightness, the first time, every time.

We connect our patented technology to your home via a modified blower to pressurize and distribute the sealing formula.The pressure carries our non-toxic, water-based formula throughout the home and effectively seals any leak by using the very air that is leaking out of the home, thereby finding any leak point; visible or not.

Have peace of mind monitoring the seal and seeing real-time result. You’ll even get a certificate of completion showing the before and after results.

Air Sealing in Four Easy Steps


Pressurize & Apply

Using a blower door, the space is pressurized. After that, a computer controls the entire process including the temperature, pressure, humidity, and distribution of sealant within sealant within the space during the process.


Seal & Monitor

With the AeroBarrier process, you see results in real time. You have complete control over your desired level of air tightness and can achieve any level required. At the end of the process, a final blower door test is run to verify the air sealing results. AeroBarrier then provides a Certificate of Completion that shows pre and post leakage.


Clean Up

After the air sealing is complete, work can resume in the space within 30 minutes. At that time, clean up of all equipment and removal of all tape and coverings can occur.


Prep & Setup

Prep the area by covering any openings that won’t be sealed. This includes taping or covering any designed openings or finished horizontal surfaces within the space. Emitters are then set up throughout the area to be air sealed.

The equipment is then set up. This includes blower door, emitters, hoses, and the AeroBarrier machine.

AeroBarrier FAQs

How does AeroBarrier 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.

Is AeroBarrier safe for the environment?

Our formula is a water-soluble organic compound and is proven safe. The sealant is ultra-low VOC and because it is inert there is no chemical reaction needed to form a seal meaning there is no off-gassing. With more than 150,000 projects sealed to date, we’ve helped hospitals, surgery centers, schools, and public buildings make sure their air is clean, healthy and comfortable – and saved them energy and money in the process.In fact, our sealant is GreenGuard Gold Certified, meeting the stricter certification requirements used in schools and healthcare facilities.

What size leak will AeroBarrier 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.

Can I be inside the house while AeroBarrier is being 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.

How long does the install process take?

This depends on the size of the home and your desired ACH50 goals, but most projects are completed in 4-6 hours. This includes the time from arrival on site, through prep and installation of AeroBarrier sealant, to clean up and completion.

How soon can I re-enter the house after AeroBarrier?

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.

What prep work is required prior to installing AeroBarrier?

The key thing to consider when preparing a home for AeroBarrier is to determine if the house can be pressurized. This means all the windows and doors must be installed and any other openings in the home can be closed or otherwise sealed shut to perform the test. Our technicians will then tape over all any portions of the windows and doors that we do not want to seal shut. We will also protect mechanical equipment by taping over supply and return grills so no sealant enters the HVAC ductwork. Lastly, we will cover over any exhaust vents to the exterior of the house. This could include bath fans, range hood exhaust, fireplace flues and your dryer vents.

Does weather affect the install process?

Although the sealing equipment can heat the air as it seals, there are practical limits to aerosol sealing when it comes to weather conditions. Ideal outdoor temperature is 40˚F or higher. Sealing can be done when the temperature is below 40˚F, but additional steps may be required.

How is leakage measured with AeroBarrier?

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.

What is AeroBarrier made of?

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 AeroBarrier 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.

What is a modified blower door?

AeroBarrier modifies its blower door by adding a heater onto the fan. This allows the system to achieve optimal room temperature and humidity during the sealing process, allowing more sealant to be sprayed into the space for a faster, more efficient sealing process.

At what stage of construction can AeroBarrier be installed?

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 affect install is the build process (i.e. vented or unvented attics) and the site’s climate zone.

What is ACH50?

ACH50 is the abbreviation for air changes per hour at 50 pascals (Pa) pressure differential. This is the most common metric used to determine the air tightness and energy efficiency of a home. It represents that total number of times the full volume of air inside a building can be sucked out (or pushed out) of the house at 50 pascals of pressure. In most climates zones where we install AeroBarrier, a decent ACH50 is between 3.0 and 5.0 with the lower number representing a tighter envelope. We often seal below 3.0 for our customers that want greatly improved efficiency. Once you get to 0.6 ACH50, you have reached Passive House certification levels that represent truly remarkable energy efficiency.

I heard a home can be too tight. Is this a bad thing?

A home that is too tight can be a bad thing if the space isn’t designed for that level of tightness. The popular saying “build tight, ventilate right” applies here and works both ways. Building tight without proper ventilation could cause issues with indoor air quality (IAQ) in the space. On the flip side, a leaky home with proper ventilation could cause the mechanical system to not work as it is designed. Because AeroBarrier can dial in the desired tightness of the space it removes the guesswork and ensures that the home is only as tight as the space is designed for.

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. Most of our applications are in the range of $1.25 per heated square foot.
