Product reviews: Easy Order Window Inserts Online

I ordered 4 custom window inserts of all slightly different sizes due to living in an older house. The inserts were received in on time and perfectly wrapped to prevent any damage. All the inserts were numbered 1 through 4 as prescribed and fit perfectly! I cannot even tell that they are in because they are so clear and fit so nicely. Also, and just as important, I can already feel the difference in the room temperature. I would highly recommend WindowInserts and would definitely order from them again.

Thanks You!

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 bought three sets of inserts for original Andersen single pane casement windows as I did not like any of the options for replacement windows, That was 2019. They have held up just fine, cut down on drafts. I only remove them for cleaning as our NEW heat pump is either heating or cooling, no need to open windows

We received the inserts late this afternoon and have installed them. They were perfect! Thanks for being so speedy. We will be passing on information to friends and neighbors, hoping they will order some, too.

The inserts are holding up really well. I have used them each season for the last three winters. Although the material appears light-weight, it is actually quite sturdy. The temperature difference at the windows with the inserts is very noticeable, and the room stays much warmer than it would be otherwise.

I've had my Windowinserts for a year now and can now give an honest review of the product. Working for a utility company, I'm always looking for energy efficient ideas and products. From my first contact with Eric, to delivery and fit, Windowinserts have surpassed my expectations. Living in a 2 story house, there used to be a distinct temperature change when walking from the kitchen into the living/dining area. Both areas have large double pane windows, and used to feel the cold radiating from the glass, but no more. We recently had a cold snap, with temperatures dropping below zero, and there's still wasn't any cold radiating from the windows. What a difference! Upon Eric's recommendation, I left the inserts in during the summer, finding it easier to cool the house as well. I highly recommend Windowinserts for anyone frustrated with cold, drafty windows, as a cost effective alternative over replacing existing windows. Thanks so much and keep up the good work.

We received and installed our 18 window inserts back in October and installed them just before the cold winter hit Downeast Maine in November. Since mid-November, it has been unusually cold here, average temperatures in December at least 5 degrees below normal. The inserts have performed wonderfully; indeed, I don't know how we could have survived in our old, un-insulated farm house without them. You have a great product, and you handled our order and delivery with a very high degree of competence. Many thanks!

I recently ordered 5 of your window inserts for my basement egress windows that are “exposed” to daylight. I received them today and installed them. They fit perfectly and were very easy to install. I could tell a difference as soon as I put them in! The drafty air stopped immediately! We will be ordering more for some of our “West” facing windows in the upstairs. Thanks for a great product, lightning fast shipment and saving us money on our heating bill!

My wife and I recently received 30 inserts, and we are delighted by them. Each one fitted easily in the space it was made for, and we could instantly feel their effectiveness. The service you provided was excellent, and we can highly recommend these interior storm windows to anyone living in a cold climate!!

Eric, you’re a genius, man! Your shipment arrived damage free, and the installation was a piece of cake. I just installed 13 window inserts in under and hour, and most of that time was devoted to working around the shades and curtains to gain access to the window openings. Many thanks for a great engineered product and your fine customer service.

Amazing!!! My daily power usage was $24.00.
After the inserts, it is $10.00
They just paid for themselves.

I installed 57 window inserts in my home a year ago.

I have been in my home 50 years. In winter the north wind would blow thru cracks around windows.

After installing window inserts fitted perfectly to each window my house has no drafts. It is like being in a warm nice cave.

I received the window inserts today and have already installed them. Our home is in a historic section of Beacon Hill in Boston so we are restricted as to what we can install. These window inserts cannot be seen at all and have really cut down on the drafts through the old window sash. I would recommend this product.

Very pleased with our new window inserts—no more chipping ice off the steel window frames, no more pools of water on wood window sills, not to mention the dramatic drop in cold air coming off the windows.
Thanks,
Syd

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.

I purchased these inserts without my husband's knowledge and this was the BEST money I ever spent. I have had the inserts in for only 3 days, put them in myself, and the difference in temperature near my huge bay windows , each 93 inches wide, is barely perceptible, I came home to a power outage, temps in the teens, and my house was still warm. I intend to purchase inserts for the rest of the windows in my home. Thanks for such a wonderful product!

I live in Northern Ontario, Canada and as I could not find a similar product in Canada, I decided to purchase inserts from Energysavr. I did a trial of 11 windows. Unbelievable product! -45 celcius and no drafts. House nice and warm. Excellent product. Received personal phone call as well. Customer service above and beyond. Thank you for making a great product
