If you’ve ever wielded a tube of icing to decorate a cake, you can certainly apply caulk to your windows. Similarly, if you’ve sealed an envelope with tape, you’re more than capable of installing weather-stripping. And if you’ve wrapped gifts, you can fashion a temporary double-pane window.
While these winterizing tasks may seem simplistic, they are among the most effective methods to control your electricity bill during the colder months. Ensuring your windows are airtight is crucial for home energy efficiency. According to the U.S. Department of Energy, up to 25 percent of the heat you’re paying for might be escaping through cracks, gaps, and holes in your windows.
Identify Problem Areas Approach your winterizing project systematically to maintain your sanity. Begin with a thorough inspection of each window, both inside and out. Look out for cracks, gaps, or holes by:
Using a feather, long-stemmed lighter, or smoke pen on a breezy day to detect movement. Sensitizing your hand with water on a breezy day and running it around the window casing. Examining the perimeter of the window with a flashlight in the dark to reveal problem areas. Mark any identified issues promptly with sticky notes to address them later.
Caulk or Weather-stripping? Before proceeding, consider whether to use caulk or weather-stripping. The Department of Energy offers a useful guideline: use weather-stripping for movable components and caulk for stationary ones.
Read the instructions on the caulk tube or weather-stripping package before starting. Gather necessary tools, such as rags, a putty knife, scissors, and a plastic bag for disposal. Clean and dry the window thoroughly before application.
Caulking Tips Apply caulk when humidity is low and the outdoor temperature is at least 45 degrees Fahrenheit. Maintain a consistent angle with the caulk gun to ensure even application. Apply caulk in one continuous stream rather than intermittently. Opt for a thicker layer of caulk for better sealing. Use a putty knife to guide excess caulk back into place if it spills. Weather-stripping Tips Apply weather-stripping when the outdoor temperature is at least 20 degrees Fahrenheit. Place weather-stripping between the sash and the frame without hindering window operation. Measure and cut weather-stripping to size before application. Create a Temporary Double-pane Window If replacing windows isn’t feasible, consider creating a temporary double-pane window using clear plastic or vinyl sheeting. Secure it with weatherproof tape, duct tape, or tacking strips.
Window Treatments Matter Maximize the efficiency of your windows by adjusting treatments accordingly:
- Keep them open on sunny days to let sunlight in.
- Close them on cloudy days and at night to retain heat.
- Consider using quilted drapes or insulating liners to minimize heat loss.
