What is AeroBarrier?

Efficiency First Air Sealing is operated by experienced PEI contractor Robert MacLeod. He is using innovative new technology from Aerobarrier to transform the air sealing process in new construction, renovations, and retro fit housing.

Historically, energy savings derived from building envelope enhancements have been challenging to achieve. At the same time, standards for envelope tightness are escalating. AeroBarrier, a new and innovative envelope sealing technology is transforming the way residential, multifamily, and commercial buildings seal the building envelope.

AeroBarrier can help builders meet any IECC, Energy Star, or passive house requirement more consistently and more importantly, more cost-effectively than traditional envelope sealing methods.

AeroBarrier is an interior applied air sealing system that seals all building envelope leaks up to 1/2. The safe, waterborne acrylic sealant is applied by pressuring a targeted building area, then spraying the aerosolized sealant into the pressurized space. The sealant is applied in as little as 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.

How It Works

1. Setup

Equipment is set up at the job site. Conveniently transported by trailer, AeroBarrier install equipment is mobile and portable. The equipment includes a compressor, generator, blower door, emitters, hoses, and the AeroBarrier machine.

2. Prep

Prep the space. This includes taping or covering any areas that won’t be sealed. Emitters are then set up throughout the area to be sealed.

3. Pressurize

Pressurize the space with the use of a blower door. A computer does the rest, including the control of temperature, pressure, humidity, and distribution of sealant during the process.

4. Seal

See the results in real-time. Throughout the application process, the computer monitor displays the ACH improvement, allowing you full control over your desired level of envelope tightness and the leakage reduction.

5. Certify

Run a final blower door test to verify the sealing results. At the end of the process, receive an AeroBarrier Certificate, with a pre and post leakage report.

Guaranteed Results

Measurable Results

As AeroBarrier is applied, the results are displayed in real-time. By incorporating a blower door, the AeroBarrier system is able to dial in your desired leakage. It’s that easy and verified upon completion.

Fast & Easy to Apply

From start to finish, the sealing process takes as little as 90 minutes. In new construction applications, prep and clean up time is minimal – typically taking less than an hour. Once set up, the AeroBarrier machine takes over and manages the sealing process through completion.


No more caulking needed to weatherize a space pre-drywall. Meet and verify air tightness requirements in real-time, avoid sealing guesswork, and save on time, material and labor.


Sealant achieves durability performance in 3 key areas: flexing, aging and compatibility in tests simulating 50 years of service.


GreenGuard Gold certified with ultra-low VOC content and no off-gassing. Work can resume in the home within 30 minutes.
