This guide discusses the practice of weatherizing your home through weatherstripping. Selection of materials, types of weatherstripping and buying and installing these products are discussed.
Insulation is not the whole story for energy conservation! Even if your home is well-insulated, energy may be wasted through air infiltration. Air can leak around doors and windows, foundations, chimneys, exterior plumbing, etc. In the winter, air heated by your furnace is lost to the outside; in summer, hot outdoor air puts an extra load on your air conditioner. If your home is typical, one-half to three-quarters of your fuel bill is the result of air infiltration.
Weatherizing your home by caulking and weatherstripping can effectively reduce energy waste. In fact, the cost of caulking and weatherstripping can usually be paid back in energy savings in less than one year. This makes weatherizing one of your best investments in energy conservation. Even better, it is something that you, the homeowner, can do!
