Exceptional Air Sealing
In Napa Valley, CA

Our Process
Whether the building we are sealing is 500 square feet or over 10,000 square feet, our three-step process remains the same.

Our Three-Step Process

  1. The first step is taping off all of the surfaces that do not need the sealant, all non-sealing joints, and setting up the equipment for sealing.
  2. The second step is the pressurization of the building and the introduction of the sealant into the space. This is when the building envelope begins to become sealed.
  3. The final step is cleaning up the home, removing all of the equipment, removing the masking, and certifying the home’s ACH50 level.

Frequently Asked Questions

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 leaking 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.
