Are Your Walls and Ceilings Ghosting?
Periodically, you will see faint dark lines in ceilings (sometimes walls) that correspond to the hidden framing. This is a condition called "ghosting" or "thermal bridging" and is caused by a difference in temperatures among the framing members and the insulated space. The cooler surface causes moisture to condense which collects dirt particles from the air. This is especially prominent when candles are burned because of the carbon by products of combustion. The easiest solution is to reduce the moisture in the air. Other options are to repair the insulation, reduce the particulate in the air and adjust fuel burning appliances.
