Escaped heat from windows can account for 10 to 25 percent of your heating bill.
Whether you’re a renter or a homeowner, drafty windows can waste energy and cost money. Some window treatments—like blinds, shades or shutters—can help, but weather stripping is even more effective. It keeps air out by creating a tight seal around doors and windows.
Weather stripping can wear out over time, so make sure yours is in top shape by checking for cracks, tears or loose pieces. You can purchase new weather stripping at your local home-improvement store. Remember to take a piece of the old weather stripping along, so you can find its match.
For a simpler, more affordable option, pick up weather-sealing tape or a home insulation kit. For just a few dollars, you can seal windows and glass doors with transparent film to keep the cold air out, saving energy and heating costs in the winter. The wrinkle-free film fits tight against your window, so it won’t affect your view.
