about

The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is closed.The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, whose Indoor Air Quality scientists tested it. The research was funded by US Environmental protection agency, US dept. of Energy, Electric Power Research Institute and California Institute of Energy and Environment.

The University of California was granted initial patents in 1996 and 1999, and Aeroseal holds an exclusive license to the technology.

Taitem and Aeroseal

For years, Taitem has encountered high performance ventilation systems (such as ERVs) which did not perform well due to duct leakage. We recommended reducing over-ventilation in energy audits and found that reducing duct leakage was essential for this to be achieved. Through our ventilation research, we found that reducing duct leakage was the most important factor in the performance of ventilation systems.

With our understanding of duct leakage and a desire to help address this issue for our clients, we decided to become an Aeroseal contractor. Taitem‘s Aeroseal services launched in June, 2011. Previously known as “Aeroseal of Ithaca”, we now provide services directly under Taitem.
