Product reviews: Easy Order Window Inserts Online

These window inserts are great! We initially ordered 26 inserts to winterize our screened-in-porch and screen door. (There was a minor issue with a couple of the inserts that was quickly corrected. This is a great company to work with!)

Since our screened-in-porch is on the north side of the house here in Iowa, we added storm window clips and some wood trim pieces for extra stability for strong winter winds. We've had our share of winter weather and everything is staying in place nice and tight. These have made an area with no glass panes quite comfortable on mild winter days and have increased our living space.

We love these so much we ordered a few more for some drafty casement and double hung windows in the house.

They are easy to install and look great!

Hello from a satisfied customer. We bought storm window inserts from you year ago for our summer cottage in Castine, Maine. Our application was a little unusual and a tough test for your windows. We wanted to turn a screened in porch into a 4 season room. The problem was we only had ancient, large wooden frames holding screens, each custom built to fit non-standard openings, and we weren’t ready for a major overhaul to install permanent windows. Instead we ordered nine window inserts from you to fit inside the screen frames for winter use. Although they felt fragile, the window inserts have held up to everything a Maine winter can throw at them… below zero temps and gusts over 50 mph!. The only modification we made was for the wind. Since frame tension wasn’t enough to hold them in place, we mechanically held them in place with storm window type clips screwed into the wooden frames.

This arrangement has worked perfectly for two winters. At first I was amazed that they stayed in place in the harsh weather, and had started to take them for granted when I was reminded how tough they actually are. After a particularly windy snow storm one of the window inserts blew into the porch when a gust bent the aluminum frame and the insert escaped the clips I use. Once that panel came down, the gusts blew one of the screen panels completely off the cottage and into a field twenty feet below us.

When we visited the cottage we found the wreckage and started repairs. I was amazed (again) to find both inserts intact and ready to be replaced! The first one with the bent frame had bounced off of porch furniture but was not ripped or damaged. I simply straightened the frame and reinstalled.

The second one was still attached to the screen panel, out in the field and covered in snow and ice. After repairing the hooks and eyes that had been ripped out of the screen panel, I reinstalled the panel with the intact window insert still attached! After a day most of the ice has melted off the window insert and everything is fine.

EnergySavr window inserts are tougher than a Maine winter! Here is a picture of the installation showing two of nine window inserts. Note the size of the panels and imagine the force of the wind gusts.

Thank you for an excellent product.

I bought window inserts from you about a year ago and am very happy with them and wanted to let you know. We have a large sun porch on our house that was built in 1910. The windows are single pane and it used to be unusable in winter. Today is very cold starting at 10 degrees with a wind chill that is below zero. I just opened the French doors and cautiously stepped into the room. Much to my surprise, it was very warm and comfortable to sit in. We also insulated the floor, but I attribute most of the change to your inserts.

Thank you for dramatically expanding the useable space in our home. The inserts provide great insulation and are attractive too.

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!

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

Just a quick note to tell you how much we're enjoying our new window inserts! They have transformed our older home's ability to hold in heat and keep the winter winds out. We've never experienced a cozier start to the deep winter.

Thank You, Thank You, Thank YOU!

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 WHOLEHEARTEDLY RECOMMEND THESE WINDOWS AND COMPANY

I've had my window inserts for over 2 Michigan Winters. They are used in a screened in 3 season room WITHOUT GLASS WINDOWS.

These windows are AMAZING! The windows perform better than expected, or advertised. My non-heated space is normally 20 to 30 degrees WARMER than the outside, and goes as warm as 80 when I use the hot tub. These windows have withstood artic blasts of wind over 50mph without failing, they are incredibly light, and beyond easy to put into place thanks to the company numbering them.

You can NOT go wrong with these windows! The company is amazing to work with, attentive, and honest. The product is top notch, even if your initial impression is, like mine was, "no way this is working".. order them, put them in.. I promise you won't regret it!

I ordered and installed 21 inserts in a 113-year-old county Museum and another 15 in a restored railroad station of equal age as the Museum. The savings for both buildings have been in the hundreds if not thousands of dollars. The installation was quick and easy. Only one has been wrong and it was my error, as I forgot the double-hung window was not split in the middle. I have recommended this company and their product to many people.

Hey Eric! I just wanted to drop a quick note that I received in my inserts and I also have already some of the Indow window inserts and OMG you guys are phenomenal. Outstanding job, the white is actually White, they are not 8 ft by 8 ft so I can take them out myself and clean them when the time comes. You guys BLOW Indow out the window. LOL THANK YOU

My only regret so far is that I did not know of you guys first and that I did not trust in the fact to order for my entire house this first time!

Immediate difference once installed. Ordered for 8 windows but 3 were wrong sizes. Customer service was great and had replacements in about a week. Even refunded initial shipping for the incorrect inserts. I have 14 ft of windows for my main living area and it is always colder and drafty. Now it feels like the rest of the house. I put in my BRs as well and huge improvement at night now that its getting colder (low 40s). I will be ordering more for my back rooms. Highly recommend especially if you have older windows like I do (casement).

These are a fantastic product. The custom fitting according to my measurements is absolutely PERFECT.
It seals my drafty sunroom which has eight storm two-pane windows and nothing else for insulation. I put these in and presto! No more draft. It allows the sun to heat up the room nicely.
I made an error in measurements for one window, and Jessica solved my problem immediately. Not only that, she came up with a two-insert solution for the storm door, and saved me a lot of money for the item AND the shipping.
I really love it when things exceed my expectations. Both the window inserts and the customer service do just that.
Thank you Windowonserts!

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.

Love, love, love my Window Inserts! I have 2 large drafty old windows in my historic home. For years I have wanted to get storm windows but the cost was prohibitive. These inserts installed in a snap and they look great. Eric and his team are the BEST! Their customer service is second to none. They are very responsive and helpful. And my order was in my house in a week from my placing my order!! Thank you!

I love these storm windows! We have an old house that had triple track storms on the house when we bought it. They were so difficult to operate, that our windows were always dirty because we did not want to go through the hassle of moving all the sections of the storm and the difficulty of getting to the outside of the primary window. I took them all off to do maintenance and paint. When they were off, we couldn't help but see how much better the house looked with the windows visible. It was also obvious how much easier it was to clean the outside of the windows. We decided to look for inside storms and after much research decided on Window Inserts. They are really a great product. They install easily and look great from the inside. They seal better than our old triple tracks as well. So, it seems to be the best solution. Good sealing against our NE winters, good looks from inside and outside. Light weight and easy to install and remove for cleaning. If that wasn't enough, the customer service is also terrific. We are sold!!!!

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!

After 3 years installed, these windows are still wonderful! They paid for themselves after one year in utility savings alone. Easy to install/uninstall, clear, and air tight, what more could you want. I have a historic home and while I love my original windows, I don’t love the drafts. No more window film, no more temporary fixes. They look as great as the day I got them.

Hi from Northern Michigan where the wind drives our weather here right off from Lake Michigan. 15 years ago I bought window inserts to stop the draft in my 50's ranch house. Original Anderson windows in beautiful condition, but SINGLE PANES! Wow!! These inserts have been the best investment. They make my house cozy in the winter, stop the wicked North wind and DROP my energy bill!
I can't recommend this company enough. There hasn't been a singe disappointing thing about the experience. Measuring was easy. My window inserts arrived in perfect condition and went in beautifully. They look great too! I give customer service a 5 star review all on it's own!

We cannot say enough about this company. We have had these Windowinserts for over 10 years and they are great. We use them in the winter and they make a big difference in warmth and still look great. Nice folks too and excellent customer service..

What a great product and company! I bought 9 inserts in Oct of 2015. I live in cold northern Vermont, and a house with very good insulation. These inserts are 100^% as advertised. Great looking, fit, quality of frame and plastic are Top Notch. Always have great interaction with customer service! Thanks for providing a great solution.

The inserts function exactly as advertised, and they earn very high marks, along with your excellent customer service.

Many thanks!

My second set of inserts just arrived and were installed within minutes and fit perfectly. These were for a screened in porch which has the afternoon sun and the inserts make it so much warmer. The first set were for the main house windows and believe it or not the electric bill just arrived and is $80.00 less. A true believer that proper insulation helps control the heat loss during the colder days. Just buying this home in late September and trying to find ways to cut the drafts I looked at many ways and found Window Inserts and decided to try them and know it was the best purchase ever made. I will recommend doing this to anyone that has issues with drafts, heat loss or even to help with sound blockage as these inserts have done it all !!!! Great Job and Thank You...

Ordered these for a screened in back porch. They fit great, look great and keep the porch so much cleaner and warmer in the winter. We are able to use our back porch so much more now. Great product! Easy to install and remove. Great service! Nice doing business with this company.

WindowInserts has made a tremendous difference in the comfort of our home. No more drafts! And the energy savings is very significant - at least $50/month. Best home improvement investment we’ve ever made.

I live in a house built in 1870. The windows are original and not the best at keeping the cold out. Luckily I ordered these window inserts and they arrived just a few days before the big temperature drop. Even with the temperature drop of more than 30 degrees down to -5F, my house feels warmer. Best money I have spent on my home! I just did the first floor this time around - ready to do the second floor now!!!
