Product reviews: Easy Order Window Inserts Online

Have inserts in all my windows, can tell the difference already. I changed my furnace filters so I should know on my next utility bill if there is a big difference. Will post again towards the end of December.

WOW! I am THRILLED with the inserts. They arrived yesterday and were easily installed on my screen porch in a half hour. They are clear, don’t distort the view and keep my porch at least 10 degrees warmer and with a space heater, 20+ degrees warmer.
Everything about this transaction has been spot on. It is little wonder the reviews are all so positive. Thank you so much for your fine product and personal attention. This has been the best decision I’ve made lately.

In December of 2018 I ordered 9 Window Inserts for my old oak windows that were streaming cold air into my home. I waited two winters before leaving a performance review because I wanted to see how effective they were. I am amazed at the difference in energy savings & the warmth of my home. We recently had a wicked wind storm that downed trees and I was shocked that my Window Inserts were not blown out across the room! I love the fact that once installed, I barely even notice that they are there. I have very deep window sills and collect crackle glass, so I can arrange my collection on my window sills and encase them with the Window Inserts for a dust free display! One insert is over my kitchen sink, which gets splashed on occasion, but it is easy to wipe clean with a cotton cloth...just like new! I love these Window Inserts as they work well when using the central air conditioning, as well. The Window Inserts paid for themselves in just one winter of fuel savings. Absolutely amazing! I priced glass inserts and these, by far, are an economically wise choice! I highly recommend the Window Inserts and I only wish I bought them many years ago!

I already have great thermopane windows with argon gas, etc, so it made no sense to get these inserts and possibly a waste of $$. I have no regrets. The heat feels more even throughout the house, and I don't worry I'm wasting energy when I punch up the thermostat another degree to be comfortable. This is the cheapest way to get the effect of triple pane glass. And they go in and come out so easily!

I just wanted to drop you a note saying how happy I am with the window inserts. They fit great, and the drafty kitchen is now cozy. So easy to measure and install.

Thank you and happy holidays!

Just WOW! I started my project last winter and added the last 2 windows this week. My first purchase is already paid for from my energy savings and these will complete my home. This products performance is amazing. This product along with my wood blinds are saving 25-30% on my energy cost. Money very well spent!

We purchased these last year for our log cabin. Order #28409. They are totally awesome and no drafts coming in. We just put them in again today which reminded me that we didn't leave a review last year. Fabulous company, fast shipping, great customer service. We had one larger window and they called us and told us we had an option that would cost less if we ordered two inserts for the large window instead of one large insert. A+++++++ Company and great product and we love being able to see clearly out of the windows with the window inserts installed.

I received my Windowinserts on December 10, 2021. I installed them in about 15 minutes on two windows that I believed were leaking cold air. The feeling is much warmer now, They were a breeze to install, no tools needed, and almost disappear into my brown windows. They were well packed and I will save the packaging to store them in the summer months.

I got the 3 window inserts this morning and all 3 installed easily. Thank you very much.

I am super happy with this product! I installed them the moment they arrived, which by the way was faster than I expected. They were well packaged and fit perfectly into my 6 living room windows. That night happened to be an unexpected cold snap, and I was so shocked at how comfortable I was in my living room. I had to check the outside temp a few times because I was so used to cranking up my heat on days like this. They look great too. Like they've always been there. Not to mention that I checked around and the price was great, and they are all-season which other brands aren't necessarily. Customer service is great. Eric had a question for me and I'm glad I got to talk to him as he gave me even more confidence in this product. It has saved me so much money and was so easy! I'm going to be recommending these to my neighbors who were complaining about their windows too!

Amazing customer service!
Great product! We bought 5, two of which went into skylights! We called after measuring and the gentleman helped us. They arrived and were well packaged and wrapped nicely so they didn't get damaged in transport. Install was easy and you can't even tell they are in the window- much better than the plastic and tape we had up before! I only wish I knew about this before we moved!!! Would have helped with our drafty windows! Definitely highly recommend them!

I purchased my Window Inserts last year and love them. They help reduced my heating and cooling cost and are barely noticeable.

The team at Window Inserts is considerate and responsive, I enjoyed working with them. Would definitely recommend.

Great product and great customer service!

Windows Inserts are a great product! They are easy to order and install. Above everything else they do there job. They look good and keep the drafts out. Having a townhome in the northern part of New Jersey on top of a mountain called for help and I got it from Window inserts. I highly recommend the product. I have ordered 7 so far and I am very happy with the whole process.

I just installed the 3 window inserts that I ordered, so easy to put in and the tan color matched my windows . Love them will be ordering more before next fall.

ordered windows very easily thru customer service they were very helpful the product is very nice they are working excellent i would buy more without hesitation if i needed more, they really work period don't wait to order winter is coming to an end and why should you not be comfortable !!!

I ordered the window inserts based on other reviews and agree with everyone. These are a wonderful energy saver, we noticed an immediate improvement. In spite of having newer double pane windows, we had noticeable cold air coming in around the bottom of our windows. That was virtually eliminated with the very easy to set in place inserts. Eric called to review our order, made a couple of changes and ensured they were delivered on a tight line we had. A builder visited our home and was very impressed, he had not seen anything like these before. We are very pleased.

Extremely pleased with the performance of these inserts on a 70 year old house! Even during single digits in the North Georgia mountains snow storm the house remained toasty warm and no draft. The difference is remarkable.

I would rate you 10 stars if that was an option! From initial ordering to the finished product, I am extremely pleased. (updated)

Very happy with your inserts. Fit perfect and look great. I mistakenly ordered the wrong size and they sent me replacements without charging me for the inserts or shipping. A great company to do business with and a great product. Thank you so much.

These are fantastic. Overnight was minus 10 oF. Saved money right out of the box. Thanks. No drafts.

The window inserts make the windows look as if nothing has been added to them; and they do keep the cold draft out in MN winter time. Thanks for the great product.

I’m really happy with the window inserts. I had to delay the delivery and it was delivered perfectly in time, just as promised. All window inserts fitted well and checking my electricity bill I found out that energy consumption went down 40%. I’m curious to see how much it will be in winter.

I cannot express how highly we regard this company and their window inserts. The quality and quick service was great!!
We were concerned about the inserts not working because our windows have a lot of quarter round that might prevent a tight seal. After trying out one window we found the inserts still fit great! We ordered 11 more for the rest of our windows. They are so easy to install and made a difference right away!!! Can't express how great these are. We could not afford new windows and our heating and cooling bills were very high. The value is fantastic. We can check our energy usage online and have already seen a reduction. Be sure to measure carefully. We measured one window incorrectly and had to re-order. The customer service was far above what we even expected. They worked on getting us a replacement insert as quickly as possible and were very understanding about our mistake and didn't make us feel bad for not measuring correctly. Again we would highly recommend the company and the window inserts.

Customer service is outstanding. Received my order of six large inserts in 8 days. They all fit snug. Have a skylight in kitchen and placed one there as well as the window over the sink. The kitchen not only felt warmer but the thermometer showed a 2 degree increase in temperature within three hours. Follow the on-line instructions and you should have no problems. Only drawback are the color choices. Maybe an almond or beige color to cover all the bases. Fantastic product.

I live on a lake approx. 90 miles north of Houston, Tx. My house faces north and has 12
single pane windows across the front that give me an unrestricted view of the lake.
Natural gas is not available where I live, so I have electric heating.

In 2009, I experienced several "blue northers" (cold fronts from the north) that resulted in very high electric bills (over $500 a month for three months)
I considered double pane windows to replace the existing windows, but every cost estimate I got was in excess of $3500.00

I searched the internet and found the window inserts and purchased 12 inserts in 2010.
Since installing the inserts, my heating bills have been reduced by approx. 50%.

I highly recommend using these inserts to lower your heating costs.
