Laboratory and field testing of an aerosol-based duct-sealing technology for large commercial buildings.

Author(s) : CARRIÉ F. R., LEVINSON R. M., XU T. T., et al.

Summary

Laboratory and field experiments were performed to evaluate the feasibility of sealing leaks in commercial duct systems with an aerosol sealant. The method involves blowing an aerosol through the duct system to seal the leaks from the inside, the principle being that the aerosol particles deposit in the cracks as they try to escape under pressure. Methods and devices specifically devised for this application proved to be very efficient at (a) increasing the sealing rate and (b) attaining state-of-the-art duct leakage classes.
