Winterize Your Windows with Thermal Curtains


I know that during the winter, it’s not ideal to have the thermostat set in the 70s.  But my husband and I both grew up in tropical climates, and as a result, we like the house to feel a little — well — tropical. Not to mention the fact that I get chilled to my bones really easily. Of course, that typically leads to a much higher natural gas bill during the winter when we’re trying to keep the house warm and cozy. Not great for our pockets.

We’ve been keeping the thermostat as low as we can bear, but we’ve also been trying to find other ways to minimize our heating costs. So when Walmart gave us the opportunity to winterize something in or around our home or car, we saw it as an opportunity to finally make a dent in that pesky gas usage.

As apartment renters, we can’t make any permanent changes to building structure, and our community’s maintenance team handles a lot of other tasks as well. In other words, we couldn’t install a programmable thermostat or new custom screens aluminium windows, and I didn’t think they’d take too kindly to us shrink-wrapping the windows. So what could we do?


Simple. We headed to Walmart and picked up some Eclipse energy saving curtains. These “therma-back” curtains are lined to help keep cold out during the winter and keep heat out during the summer. And we have a 10″ wide glass door in the living room that was begging for something warmer than just ugly vertical blinds. We got a new beautiful door, click on this link to see it. As a bonus, these curtains also block out 99% of light and help reduce noise, which will make for some awesome movie nights and hopefully make our neighbor’s howling dog a little more bearable.

We opted for the Eclipse Kids Dayton curtains for two reasons: We needed three curtains to cover the great expanse that is our glass door, and they were more affordable than some of the other Eclipse options at $12.96 a pop. We also liked the grommet top style, rather than rod pocket, which I hate. We grabbed three panels in navy, a great choice since they’ll mirror the dining room, which has navy painted walls. (aff)

The curtains were a great first step, but 84″ was the longest option available in store, and I knew they wouldn’t be long enough. Using an old decorator’s trick to make ceilings feel taller, I like to hang curtains high above the window (or door) line, which means I usually buy 92-108″ curtains. I couldn’t go all the way to the ceiling in this case, but even so, we still had those hideous vertical blinds to cover. When we hung the curtains, as is, we were left with an almost 10″ gap between the bottom of the curtains and the floor.


Not a good look, especially because you could see the ugly blinds. Time for plan B.

I found an old white curtain panel that we haven’t used in years and cut it to add a 10″ white panel to the bottom of each curtain so they just graze the floor.


Perfection! We love the nautical look of the navy and white, and they look amazing next to our red sofa and orange lamp.

While the white bottom panels are not lined, the fabric I used is really thick, and we can already feel the difference.  In weeks past, walking past the glass door first thing in the morning or at night meant an instant chill. Now, the temperature in front of the door feels the same as the rest of the room.

Not bad for $39 worth of curtains. I’m hoping to see a difference in our heating bill over the next month or two. And now, we need to get some lined curtains for the sunroom/office space, because I am usually freezing during the day while I work.

Hi! I'm Jennae Petersen and I'm the eco diva who had the bright idea to share my journey toward green living with the blogosphere. Some of you may know me as the founder of Green Your Decor, my blog about eco-friendly home decor, as a Walmart Mom, from Twitter or from my organic cotton t-shirt line Differently Clothing. Stick around for a while!


  1. I love your site and often tweet from your blog, though I just do a manual copy and paste. I love this idea. It is freezing downstairs and I believe this is going to be my next project! I like the way you handled the bottom not being quite long enough. Very creative. Please feel free to visit my site. I make handcrafted jewelry featuring natural gemstones and am having a monthly free jewelry drawing, starting this month. Keep up the good work. Oh, BTW, your husband has great taste, love the colorful Toms 🙂

    1. Thanks Jacqueline! The curtains have already made a big difference, so we’re planning to get more thermal curtains for other rooms. And I will absolutely check out your work!

  2. My wife and I added these same curtains to our bedroom and add a similar setup in our office during the winter. It really has made quite a difference in terms of taking out the cold chill in the air and keeping it easier to keep our place in the mid-70’s. The Eclipse curtains seem to be the way to go. Thanks for the reminder of what it was like withOUT these curtains!

  3. That’s such a great idea! I have the same issues with legnth–my house is old and has these gorgeous huge windows–but I need 96 inches! Ack–nothing is made that long unless it’s special order. I never thought of having a band of another color on the bottom. You just made my day!

    1. Jenn, I don’t know anyone who sells pre-made thermal curtains that long, but if you want regular curtains, West Elm and Pottery Barn both make them up to 108″ long, as does Ikea 🙂 You can always put thermal backing panels behind them. Or if you don’t want to use a contrasting color, buy a third (or fourth) curtain in the same style and cut it in pieces to add to the length of the others. I’ve done that before too!

  4. Love this post. From choice of curtains to your excellent fix for short curtains with the NAVY style navy/white colors. Awesome.

    I have recently started curating a site on soundproof curtains, and came across this post looking for info on thermal insulated curtains.

    Keep up the great work!


  5. As the winter months are starting to arrive, I’ve been looking for ways to winterize my windows (far too much heat loss). This is a much cheaper option then replacing the windows so I’ll have to give it a shot. Hopefully they give a bit of soundproofing too.
