A simple test for finding air leaks in your home is to pass a butane lighter slowly around the edges of doors and windows. If the flame bends or flickers, it indicates that an air leak is present, and you should repair or replace the weather stripping. Be sure to keep the flame away from curtains or other flammable materials.
