Cool Air Infiltration around Kitchen Window Trim and Interstitial Air Flow in Adjacent Wall - Image Courtesy of Fluke Corp ©2011
This infrared image was a real eye-opener. It was of a nice, new (supposedly high-performance) window installed in a kitchen. Unfortunately, air infiltration was evident around all of the trim, and in the adjacent electrical outlet. The conductive inspection indicated a reasonable amount of insulation in the adjacent wall, but at 20 pascal depressurization, intersitial air movement in the cavities was quickly evident.
