Is Window Heat Loss Leaving You Cold?
Are there rooms in your home that feel drafty or have cold spots? The problem could be cold air coming in through your windows. That cold air not only makes you less comfortable but can also cost you on your energy bills. Heat loss through windows is responsible for up to 30% of home heating energy use, according to the U.S. Department of Energy.
Reducing heat loss through windows can make your home cozier and save you money. Here are steps you can take.
Seal air leaks
Cracked or peeling caulk can create a poor seal on the outside of your windows. Examine the caulking on windows and replace it if needed. Visit https://www.energy.gov/energysaver/caulking from the U.S. Department of Energy for directions on selecting caulk and properly applying it to your windows.
Drafts around windows could also result from leaks between the wall and the framing. Carefully remove the indoor trimming around the window. Lack of insulation or a gap between the wall framing and the jamb indicates poor sealing. This project can be DIY, or you may feel more comfortable contacting a qualified professional.

Install storm windows
Storm windows save energy by reducing air leakage. They can be installed on the inside or outside of windows and are available in plastic or glass. Interior storm windows are more convenient and easier to install and maintain, while glass units offer better visibility and longer life. Plastic panes cost less and are easier to install and remove.
Attach window film
Window films are available as a simple DIY project for reducing winter heat loss. The film is typically sold in sheets that you can cut to fit each window. Attach the film to the window frame with double-sided tape, then use a hair dryer to shrink it, creating a tight seal. Low-emissivity (low-e) window film is made from a nearly invisible metallic coating that is more effective at reducing heat loss.
Use window treatments
Install tight-filling insulating curtains or cellular shades on windows that feel drafty. Cellular shades are made of pleated fabric folded to create “cells” that trap air, which helps reduce nighttime heat loss through windows and minimize cold drafts near windows.
If you have older, single-pane windows, consider replacing them with high-performance ENERGY STAR-certified models. ENERGY STAR windows are more efficient than standard models and can significantly reduce your heating costs and improve the comfort of your home.
