Window and Door Replacements
Window and door replacements are usually part of an energy retrofit. When looking at a heat loss calculation air infiltration and windows and doors are the two largest losses of heat in a home. If the windows and doors are old, they are usually contributing to both heat loss through their lack of insulative capacity, and are contributing to air infiltration through their installation or structure. If you have old leaky windows and doors, replacing them can make a substantial impact on your energy bills and comfort.
