ABOUT THE ENERGY EFFICIENT HOME IMPROVEMENT CREDIT
Indow is a certified manufacturer of “eligible building envelope components” (window inserts) that may qualify for the Inflation Reduction Act tax credit pursuant Section 25C of IRS Notice 2022-48.
To qualify for this credit, your window inserts must be installed in a dwelling unit located in the United States and the order must be shipped in the tax year you are claiming the credit for. $1,200 is the maximum allowable credit for all qualified energy efficiency improvements in a single tax year.
Due to the complexity and uniqueness of tax law, we recommend consulting a tax advisor if you are uncertain about your eligibility for this credit.

WE just took delivery of the two window inserts we ordered. they both fit perfectly. The most difficult part of the process was me trying to hold the laser measuring device still while taking the diaginal measurment! The Indow team was helpful and the ordering process was catch free. the finished product is just as they described. once installed, you can not even tell that they are there. I will warn you, if you have larger sizes they will come in a pretty large packing crate/box to protect them so be prepared. The only reason for 4 stars insted of 5 is they have just been istalled and we shall see how effective they are at reducing cold air, but they fit so snug that I anticipate they will be very effective. Just in time too, because our area is in a low temp/low wind chill pattern at the moment.

The Indow I ordered was a perfect fit. It looks great and is an extremely well made product. The ordering process was seamless.

Noise reduction by at least 50%! I cannot hear most car that drives by now. My bedroom is so quiet! Thank you!

Easy to order and install.

Window inserts help with sound since I live facing the street and the highway

This is a 5 star company from beginning to end. I purchased the I inserts in 2017 because the bedroom on the second story faced the street. These are very effective for street noise. Noticed a problem on one of the windows recently and they quickly took care of it due to their warranty. Customer service personnel are very helpful. The price of the windows was acceptable for top quality of sleep and less noise during the day

Recently purchased the acoustic window inserts for a couple of old windows facing a busy street and they've made a huge difference in terms of noise reduction! The measuring process was relatively easy with the laser measuring tool that Indow sent and the windows were delivered faster than expected. Martin was easy to work with and we would highly recommend Indow to those looking for window inserts.

Installed noise canceling acrylic Indow window inserts to deal with the road noise at my condo, 4 lane state road is 40 feet from the condo. Expensive custom fit, but oh my gosh, they cut the noise by 75%! Decibel meter app I trust shows a 6 Decibel noise reduction, average Db over 30 minutes. Turns out 6 Db is letting only 25% of noise through! I am one happy camper…

The Indow team was great from start to finish! They were very clear about each step. After installing the inserts my home has been significantly while still preserving the fabulous city views. For anyone who lives in a noisy street or city like NYC I would highly recommend it. Leave the chaos outside and come home to piece and quiet.

From start to finish, we were very pleased with our rep, Reed, and the other staff at the PDX will call! The inserts themselves are stupendous! We purchased six total for the noisiest, road side(s) of our home. The outcome was beyond our expectations! Not only did the three rooms that bordered the road become at least 70% quieter, the other end of our home did as well! I cannot recommend Indow inserts more! The technology makes sense to add the inserts rather than purchasing new windows. Great results and thank you! Paul and Paula Spilsbury

Brian was very helpful & informative. He helped me order the correct windows for my needs. They were shipped with the utmost of care & arrived ahead of schedule. Ultimately, the Indow Windows have been very helpful in muffling unwanted noises & they have helped save on our energy costs. Thank you, Indow Window!

We are thrilled with our Indow window inserts! I'd been on the lookout for a more permanent solution to leaky windows in our third floor living space. I discovered Indow on social media but since then have learned of friends who'd had Indow recommended to them by their rennovation contractor. The entire process went smoothly with friendly reps at hand to talk through questions during measuring, etc. They fit perfectly and help us to maintain the beautiful design of the windows on our 100 year old home! Highly recommend!!

Worth the money!

For townhouse living, this solved my problem with noise from my neighbor's with my kitchen window. A considerable decrease of noise indeed! Measurements were a bit frustrating so I recommend using a laser measurement device and following directions to use a string for the diagonal. They look great and were easy to push into place. I highly recommend as an alternative to buying a new window.
