Winterize Your Windows to Save Money and Energy

We’re on the cusp of winter, so now is the time to start prepping your home for cooler weather. According to, heating your home typically accounts for 42% of your utility bill, and windows can account for 10%-25% of your heating bill by letting heat out.

Check out these tips for your windows to stay warm AND reduce your energy costs this winter!

Consider Upgrading

If the single-pane windows in your home are drafty, consider upgrading to double-pane windows made with high-performance glass like low-e or special coatings to improve your home’s energy performance. Gas-filled windows with low-e coatings can reduce heat loss by reflecting heat back into the room and are a good option for especially cool climates.

If you’re not ready to upgrade your windows, there are plenty of other ways to weatherize your windows to decrease your energy bill.


According to the U.S. Department of Energy, American households collectively use about 22.5% of the country’s energy, and unfortunately, a lot of that energy is wasted through leaky windows. So, Regardless of how new your windows may be, it’s still a good idea to check them for drafts before winter hits. To check for drafts, you can simply hold a lit candle up to your window seams on a drafty day. Add new weatherstripping around windows where necessary to prevent cold air from blowing in.

Heavy Curtains and Shades

Heavy shades can help keep the heat inside your home. During the colder months of the year, keep the curtains closed at night to add an extra barrier to keep cold air out and warm air in. During the day, keep the south-facing windows in your home open to let sunlight in.

There are thermal curtains you can purchase to take this tip to the next level, but any thick curtain is better than nothing. For extra effectiveness, layer your curtains on top of cellular shades.

Window Film

Window film is an easy way to add an extra layer of insulation directly to your windows. You can find this product at stores like Lowes or Walmart. Simply stick the film to your windows, and use a blow dryer to seal it.

Your windows will not be perfectly clear with the film on top of them, so you may want to first apply to a less visible window in your home to make sure the look does not bother you.

Install Storm Windows

If you have single-pane windows that you aren’t ready to replace, covering them with an exterior or interior storm window can help improve the efficiency of your windows. Depending on what type of windows you have, adding a storm window can reduce heat loss through the windows by 10%-20%.
