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. 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.
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. Caulking seals cracks and joints in the house. Weatherstripping reduces air infiltration around moving parts of the house, such as doors and windows.
