A dirty male hand, holding a paintbrush, is spreading caulk over a house air duct joint with a paintbrush. The caulk has been applied from a tube with a caulk gun and the brush is evenly spreading it over the joint.  Caulking residential ducts prevents air-conditioned or heated air from escaping the duct and prevents ambient air from entering the system. This is a new practice in homebuilding to increase energy efficiency, eventually it may become standard or mandatory. This is a return air line running through OSB subfloor to the basement.
