    I appreciate everything about the whole Indow window process.

    Scheduling and holding a consultation online was easy and seamless. I consultant with KAYA, and he provided a thorough easy-going no pressure to move forward until I was ready consultation.

    Incentives were clearly outlined if I decided to move forward and order to be able to make my inserts even more affordable if I acted in a timely manner with measuring and submitting my order as well as returning the measure kit.

    The Indow inserts arrived within the expected timeframe and installing them was very easy. One of my favorite parts was watching how to install video, because they used humor, and it really held my attention and put me at ease, allowing me to take in all the little details I needed to insert my Indows correctly.

    Within hours, I noticed a temperature shift in the room. It was cooler and more comfortable. The next day when I worked in my office with the Indows the landscaper was across the street with the leaf blower and there was considerable reduction in noise making it a low background buzz instead of a disturbance to the work I was doing. I’ve only had them installed for three weeks and I’ve been so happy with them. It was a great investment for that room in the house that I use for my office.

    A great product. Excellent fit. Greatly reduced outside noise. Easy to install. Very happy!! Match your frame color to your current frame color and they disappear. So glad I got them.

    Well it all starts with customer service. 10 out of 10. Brain McCracken did a great job. The waiting period wasn’t long considering they had to make the window inserts and measuring the window units with the laser was actually fun. Worth every penny!

    I purchased two Indow window inserts for two west-facing bedroom windows. These windows are exposed to the hot afternoon sun, making it difficult to cool the bedroom, and there is considerable outside noise. The Indow inserts work great at reducing the outside noise and keeping my bedroom cooler. I absolutely recommend Indow window inserts.

    Very professional from website to delivery and installation was well explained and easy.

    Noise reduction was quite noticeable and sealing from cold just as good if not better.

    Would recommend 100%.

    My husband and I can finally sleep all night without being woke up by outside noise! Indows are game changers if you live on a busy road, by a loud industrial business or just want a quieter inside environment. The customer service is pretty amazing too! Thanks Indow group for giving us back great sleep!!

    Easy DIY measuring, and an obvious immediate increase in warmth. Huge difference in a historic home with historic windows.

  • 4 Stars ⭐️⭐️⭐️⭐️⭐️

    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.
