Experience the Benefits
of AeroSeal Envelope
AeroSeal Envelope is transforming the way residential, multifamily, and commercial builders seal the building envelope by simultaneously measuring and sealing the building envelope leaks allowing builders to “dial in” the precise level of leakage and performance quickly and easily.
Sealing the building envelope has never been easier

Four Steps to Advanced Envelope Air Sealing
Step 1: Prep and 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 sealed.
The equipment is then set up. This includes blower door, emitters, hoses and the AeroSeal Envelope machine.
Step 2: Pressurize and Apply
Using a blower door, the space is pressurized. After that, a computer controls the entire process including controlling the temperature, pressure, humidity and distribution of sealant within the space during the process.
Step 3: Seal and Monitor
With the AeroSeal Envelope process, you see results in real-time. You have complete control over your desired level of airtightness and can achieve any level of tightness required. At the end of the process, a final blower door test is run to verify the sealing results. AeroSeal Envelope then provides a Certificate of Completion that shows pre- and post-seal leakage.
Step 4: Cleanup
After the sealing is complete, work can resume in the space within 30 minutes. At that time, cleanup of all equipment and removal of all tape and coverings can occur.
How it works
AeroSeal Envelope 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, and 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. The sealant is applied within 60-90 minutes and dries before system clean-up 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.

Facts about AeroSeal Envelope
How does it work?
AeroSeal Envelope is an interior-applied air sealing system that seals building envelope leaks up to 1/2″. The waterborne sealant is aerosolized and injected into a pressurized home. The sealant is self-guided to the edges of visible and invisible leaks to create a seal by accumulating across the leak surface. The sealant is applied within 60-90 minutes and dries quickly before system cleanup is complete. This ensures construction can resume shortly after the process is complete with little to no impact on standard construction schedules. The AeroBarrier system measures envelope leakage in real-time, enabling the system to dial-in specific air leakage requirements with precision and guarantee the results.
How is leakage measured?
The AeroSeal Envelope system uses a modified 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.
What is a modified blower door?
AeroSeal Envelope 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.
What size leaks will this seal?
AeroSeal Envelope 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 to seal manually, or that are missed using manual sealing techniques.
Is the formula safe?
The 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.
How large of a space can this be used?
AeroSeal Envelope has been used in apartments as small as 500 sq ft and in homes over 10,000 sq ft. As long as the space can be pressurized, it can typically be sealed. Additional blower doors can be added to increase the pressure in larger spaces.
How tight can AeroSeal Envelope actually seal a home?
AeroSeal Envelope has sealed houses to as low as 0.19 ACH50. But the value is in the system’s ability to allow builders to seal a home to as tight as it is designed for. AeroBarrier can meet any IECC, Passive House, LEED, Well Standard, ENERY STAR or Net Zero requirement.
Is a home that is "too tight" a problem?
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 AeroSeal Envelope 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.
