Your questions, answered

At what stage of construction can AeroBarrier be applied?

In Newfoundland and Labrador, the ideal time to use AeroBarrier is after dry wall or first mud. The building must be capable of being pressurized (exterior doors and windows installed) and, below 15 C, the building must be pre-heated.

How tight can AeroBarrier actually seal a home?

AeroBarrier 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.

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 to seal manually, or that are missed using manual sealing techniques.

How large of a space (square footage) can this be used?

AeroBarrier 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 does it work?

AeroBarrier 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.

“Transfer Energy has been a game changer when it comes to energy efficiency in homebuilding. As a builder who specializes in high performance homes, air sealing is always our number one priority and a difficult aspect to get right. From the first experience with Steve and the AeroBarrier technology, I realized this was the way of the future. I decided at that moment that we would change the way we build going forward. Steve's involvement with the CHBA, tireless advocacy for better building practices, and his genuine commitment to help builders and homeowners, shows me that Transfer Energy is a company that I want to align myself with in our community. There's no question I'd recommend Transfer Energy to anyone looking for those types of services.”

After a few conversations back and forth trying to understand the AeroBarrier air sealing technology we were intrigued, excited and very hopeful for this “new to us process”. Steve provided impeccable customer service - he is so personable, super knowledgeable and full of enthusiasm for his role.
