Products reviews

I bought my first batch of inserts in 2007; I have a c. 1790 cape in Maine, and I needed to stop drafts around and protect my ancient sashes from moisture. I did an addition in 2009 and bought more. I love this product! They are of high quality, are easy to handle and store, and absolutely work as advertised. I am now replacing foam on some of them, and I'm reminded of how helpful Eric was and is and feel compelled to comment again on the great product and customer service. Also, although most of my inserts are over 13 years old now, all are in perfect shape; they are as solid, clear and serviceable as the day I received them from Energy Savr. Thank you Eric and everyone else there at the company!

I love mine. Easy to install. Easy to remove. They really help regulate the temperature, and they’re attractive. No complaints here. It took about a week-maybe 10 days from ordering to delivery. I’m in Texas, where we’ve had 67 days above 100 degrees & my electric bill has been about $50 less each month from last year. I only did 2 rooms.

These are excellent. They work as advertised. Well built, sturdy, and make a good seal. I have purchased these for every window the house. They really do reduce heating costs.

I ordered one as a test to see how I would like it. WOW what a difference it makes. No more breeze coming in. I measured it and it fit like a glove. I am VERY impressed with the product. I ordered the tan and it matches perfectly. I just placed an order for 2 more and will see how these do. I am sure they will be as amazing as the first one. Thanks for a great product.

Good Afternoon
Just wanted to follow up on your outstanding window inserts.
We weren't worried about noise abatement, but it does cut it down some.
The drafts coming in our old windows are gone, which has helped cut back on the dust inside. What we were most interested in was the “R” value of our windows and that has improved dramatically.

Our monthly electric bill is down roughly a third of what it was, on average, and even more during the extreme temp periods of Dec. Jan. and July Aug.
Also very easy to remove when we want to open a window and goes right back in when we want them reinstalled.

Great product.

Thanks again.

I ordered two large window inserts for my living room floor to ceiling windows. Not only did Windows Inserts suggest that I get two window inserts for each window to save shipping charges but they manufactured the inserts to fit the openings perfectly and they look outstanding. I installed the inserts in approximately 30 minutes (took a 10 minute break between windows). These inserts appear to be well made and look very good installed. I highly recommend this company for energy efficient inserts to help save money on your energy bills. One of the best parts is that they can be removed as easily as they were installed. Great Job Windows Inserts! Love them. Memphis, TN.

Purchased inserts for six screened porch windows. The inserts arrived quickly and in perfect shape. Each were a perfect fit from my measurements, are well contructed and look great. They were easy to install and made an immediate difference to our porch. We had priced other ideas for adding seasons to our Vermont porch and the costs were going to be in the thousands. These window inserts are affordable and a better solution. We are thrilled with the purchase. Eric was extremely responsive to our questions and even called us to make a suggestion on our initial order which saved us significant money and gave us a better product. Awesome!

Could NOT be more pleased!! Can't quite believe how perfect the inserts are for this cabin (should have had them years ago), and every aspect of the order process deserves an A+ rating.
Thank you so much. You've got a great business and I hope to order more inserts for the rest of the windows soon.

For years I was not able to open the heavier curtain and enjoy the outdoors because as hard as I tried and as much money as I spent every fall on various window sealing products, I was never able to stop all the leaks, some because the bitter cold caused them to loosen.

I will have a much easier time getting through the winters and these will pay for themselves. Can't quite believe how great they are, and easy to install.

We received our window inserts today. The packaging was perfect. The inserts were numbered correctly. The first one was installed in a matter of seconds and the others immediately after. We ordered enough for our bedroom and bathroom. I look forward to seeing if they help with the drafts. So far the measuring, ordering, and installation has gone well.

Hi there,

Just letting you know that so far this winter we're saving about $100/month on our gas bill from the same months a year ago (December, January - haven't gotten February bill yet). My husband was a naysayer - not any more!

We have a new home in the CO mountains (you know where we are) at 8600 feet that we leave in the winter months, setting the thermostat on 55 when we leave, so the conditions are the same without much usage variance. In fact, the weather app tells me that on average our temps are 2 degrees warmer this year than last.... Amazing that even on a new build, with double pane, high altitude windows we had so much heat loss.

So - thank you for what you do!

Even though I'm pretty confident there is no actual air infiltration, we experienced an uncomfortable cold downdraft from the skylight tunnels in our kitchen and family room. I think it was just air being cooled up by the skylight and then rotating down into the room. I installed the inserts into the tunnels 12 inches below the skylights; I thought I might have to install some sort of support to keep them up, but they seem quite secure with just friction fit. The result is terrific, the downdraft has been reduced to almost nothing.

Living in far upstate NY near the Canadian border where we have winter. I received 14 window inserts yesterday for our year round sun room. The packaging was very good. Installation was easy and the fit is very tight. Immediately noticed that the room was quiet as it was a very windy day when I installed the inserts. I am quite sure I will use less electricity as a result but haven’t been able to assess that yet. I gave this review 5 stars but I would have given it 4.5 stars if I could have only because the windows are not crystal clear as glass giving a somewhat distorted appearance. The savings will offset this minor issue. Wonder if anyone else has noticed this. Very happy with the purchase and the windows are doing what I expected. Eric called prior to construction to check on some items with me which was great service. Happy with the purchase. Thanks

Just received my inserts and they fit perfectly! Great design and easy to install! The brown color matched my windows as well. I can already tell they are working . House is tighter and less drafty! Thanks for a great product!

I just had the first opportunity today to install the inserts. OMG, these are the nicest units I could have ever imagined. I'm a business owner along with be ultra picky about everything thing I do and buy. I can always find something wrong with every product, but

I'm have to say that I couldn't find anything wrong with your product, quality and craftsmanship. The inserts arrived right on time, the boxing method you used was just like I saw on the videos and couldn't be more perfect. Inside, the inserts were well packed and protected.

The inserts fit perfect. I felt an immediate change in room temperature, turned down the furnace right after installing them. I really impressed with your inserts. I all ready have been spreading your products to friends and my customers even before I received the inserts. Everyone has been waiting for the installation report, when I tell them how wonderful they fit a long with the quality, I'm sure that they will be ordering also. Due to my perfection standards people follow whatever I purchase.

I will be a full time salesman for your product for years to come.

Thank you and your team for building a quality product that they can be proud of right here in the USA. God Bless you. It actually took me longer to email you than it took to install my inserts. Thanks again.

I originally purchased 10 of these windows for the worst ones in my 1890's built house in Connecticut. First off, customer service was excellent, I called multiple times just to make sure I had the measurements correct and their people are great. Super helpful and they were able to figure out one thing which was causing me to have different measurements for every window. The first 10 arrived and made a HUGE difference in how comfortable my home is. The following month, I bought 10 more. We are currently spending about 1/2 as much money as we were on oil, keeping the house warmer by several degrees, and keeping doors open between rooms on the 1st floor which makes a huge difference our living space. At the holidays our guests noticed our house is much more comfortable than it has been previously. I've just purchased 7 more for the second floor and I can't wait for them to arrive. This is a great company with a great product. If you have questions, CALL! They are happy to help.

We live in Denver, in a poorly insulated 1950s home with single pane windows in several of the rooms. We originally tried 3 of the inserts out in our kitchen and immediately noticed the room stayed significantly warmer in the winter. Last year, we put inserts into 2 bedrooms and the office with similar results. We've also noticed a defininte reduction in drafts coming though those windows as well.

For the money, I don't think there's a better, more cost effective solution, than these window inserts.

Allow me to set the stage before raving about customer service and product quality.

The home is a high end custom built brick ranch constructed in 1968. The windows are Pella tilt-in double hung units. Originally they were single pane with clip-in storm windows. PIA and not very weather tight. Who cared when fuel oil was $.19 a gallon! We now have natural gas powering a base board hot water boiler system. About 8 years ago I found a antique window restorer that understood I had no intention of replacing our windows and actually listened to my idea. Short story is the ORIGINAL window sashes were routered to accommodate double pane argon filled inserts. TOUCH DOWN! Easy to clean and extremely efficient compared to the originals. But these tilt out Pellas leak air simply due to design and are still available today surprisingly.

So next I did the plastic and hair dryer trick. The argon was gone after 5 years anyway. The plastic wrap worked quite well actually but another major installation/removal PIA and grand kids love to test its durability.

In comes WINDOW INSERTS. Sure I nosed around a lot and even tested a major competitor. The bang for the buck is absolutely WINDOW INSERTS! These folks were a pleasure to work with. They are very professional and suggested shipping methods that were very cost effective. Quality is outstanding.

As the weather has turned really cold I can comfortably sit by our windows in total comfort!

Growing up, I watched my father apply spray adhesive and plastic film to our home's windows. So when my husband and I renovated a c. 1884 home that came with beautiful, but extremely drafty windows, I was eager to research new technology. EnergySavr Window Inserts were the perfect solution. Our windows are varied dimensions, and the custom measuring guide was easy to follow. Ordering, turnaround and delivery all seamless. We are extremely happy with our return on investment!

I wanted to thank you for the 5 panels. Every one was a perfect fit. It made me think how unusual it is in today's age to have anything be done exactly right, ever, instead of always messed up in some way but you're expected to be happy with it nevertheless. Either a lot of people don't care, or they just don't know the difference. These are beautiful, and there were a lot of ways a product like this could have gone wrong. Thank you so much.

Easy, Efficient, Effective - Windowinserts.com is a Winner!

I'm absolutely thrilled with my experience with Windowinserts.com! From the very beginning, the entire process was smooth and stress-free. All I had to do was take some measurements (their customer service was fantastic and helped answer any questions I had!), and within 10 days, my custom window inserts arrived at my doorstep!

The turnaround time was incredibly impressive, but it doesn't even compare to the amazing quality of the inserts themselves. They fit perfectly in my windows, creating a noticeable difference in the comfort of my home, without affecting the beauty of it. I can already feel a draft-free environment, and I'm excited to see the impact on my energy bills!
I can rest more easily knowing I'm ready for the next brutal Ohio winter.

If you're looking for a way to improve your home's insulation and comfort, look no further than Windowinserts.com. Their custom-made inserts are the perfect solution, and their customer service is top-notch. Highly recommend - 5 out of 5 stars!

Thank you for this great product! I have the inserts in all my windows and have noticed that the heater kicks on half as much as it did before. It seems quieter and much cozier! Very pleased with this investment.

I have had the window inserts for over five years, they have added to my older homes comfort, took them out this past fall to clean them and reinstalled. The ordering process is simple and deliver was as promised. I would highly recommend them if you want a cost effective alternative to replacing your windows. Scale of 1/10 I would give them a 10.

Wish I ordered years ago. I'll echo others with the quality and fit. Shipping packaging was A+ After installing, immediately noticed a marked increase in warmth! Furnace runs less too.

Measured window openings and again the next day to make sure no mistakes.

My house was built in 1920 and had many old-style storm windows that were broken when I bought it, which caused a ton of draftiness especially on windy days. Nobody makes storms anymore, and I didn't want to do the huge splurge of fully replacing windows, so I got these inserts and I could not be more pleased. They're very lightweight and surprisingly flexible, and fit snugly but not painfully tight in my windows. As I write this review, it's an extremely cold and windy day with gusts over 40mph and there is a massive difference in the draftiness-- and by difference, I mean barely any draft at all! I am beyond pleased and can't wait to see how much lower my heating bill will be this month.

If you need a cost effective, custom-sized option to help with draftiness or efficiency, I cannot recommend these inserts enough. They ship quickly, are incredibly easy to install, and have made a huge difference in my old home. My furnace kicks on less, there's little to no draftiness in my house, and the brown trim makes the inserts blend very nicely with the rest of the home. You wouldn't even notice them if you weren't looking for them.

Cannot recommend these enough!

We own a historic 1833 plantation home that we’ve renovated into a charming B&B. With many original (and old) windows, preserving the home's character was a top priority for us. While we updated the windows, it was the Window Inserts from windowinserts.com that truly completed the transformation. The best part? You can’t even tell they’re there—they’re invisible, yet so effective. Our guests consistently praise how these inserts maintain the authentic charm of the home.

windowinserts.com went above and beyond to assist us, providing exceptional communication and a delightful experience throughout the process. Highly recommended!
