Air Infiltration: The amount of air that passes between a sash and a frame; Measure in terms of cubic feet of air per minute per lineal foot of crack (margin).
Air infiltration is the major cause of heat loss or gain in a home. A reduction in air leaks will provide a more comfortable environment and improve energy efficiency in the home. Some ways to prevent air from leaking through windows include using caulking or weatherstripping and replacing glazing compounds. One of the best solutions for historic homes is to have failing windows restored; windows can also be replaced. Restored windows can last many years with proper maintenance.
