It all started with the search to find ways to improve indoor air quality…

We have continuously worked to learn more about indoor environmental quality since we first encountered EasyDECON® and began this journey of remediation of air quality issues in homes and commercial buildings. Our initial efforts were strictly around the issues of water-damaged buildings and mold growth impacting the occupants. Aeroseal Duct was our first expansion into the ventilation realm of building science. Aeroseal has been a tremendous asset in that area because it improves both the efficiency of HVAC systems and indoor air quality by reducing unintended particulate matter from entering the indoor air because of HVAC duct leakage.

AeroBarrier extends that effort by addressing the air infiltration through the building envelope in areas where traditional methods do not seal properly. Building codes have adjusted over the past few years mainly around the issue of energy usage. Less leakage and less energy is required to heat or cool a home or office. In addition, envelope leakage moves particulate in the other direction as well. Humidity from the exterior, insects from the exterior, and airborne particulate from the environment all impact indoor air quality. In June 2023, a rather unusual event occurred along the United States East Coast. Wildfires in Quebec, Canada, blanketed the Mid-Atlantic region with heavy smoke, reducing the air quality throughout the region and causing air quality alerts that forced some people to stay indoors where air could be filtered. We had a client who contacted us because they were experiencing repeated headaches they attributed to the resurfacing of hardwood floors and the installation of new wall-to-wall carpet. Investigation revealed that the problem was not the new surface on the hardwood or the installation of wall-to-wall carpet on the second floor. Instead, the Canadian Wild Fire smoke entered the house through the building envelope and its various small openings.

In new construction, this process can save time and money for the builder and provide superior sealing up to .6 ACH 50 (Passive House Standards).

In January 2023, after a full remediation due to a water event, we applied Aeroseal Envelope to this 1975-era residence. At the beginning it has over 9 ACH 50 (air changes per hour) or what would be the equivalent of 4000 basket balls per hour exiting the house through the envelope. When we finished, it had a new ACH of 2.65 or about 800 basketballs per hour in leakage.

For Builders…

The number one killer of buildings is water. Water in its many forms, from bulk water to water vapor. Our buildings, mostly homes, are built out of wood and paper, all of which are a great environment for molds, bacteria, and viruses. The builders’ main concern is how to control:

Bulk Moisture
Air Flow Control
Thermal Control
Moisture/vapor control
