No screws. No nails. No mounting bracket. Just a precise fit that pushes into place. Indow storm window inserts are custom-made for your window frames using a proprietary measuring system. Compression fit tubing lines the insert, allowing it to be pressed snugly into place.
Once they’re in, our storm window inserts make your windows perform like new double-panes. The performance benefits include:
Block out drafts & seal in comfort.
Reduce outside noise by 50-70%.
Save an average of 20% on your energy bills.
Indow inserts are interior storm windows, meaning they place inside the interior window frame. Made from 100% acrylic glaze, they blend in perfectly with the surrounding window frame – so well, you won’t even notice they’re there.
No permanent modifications. No ugly additions to your home. Just a sleek, simple design that allows your windows to shine, while letting them perform like new. If you live in an historic home? Even better – Indow window inserts are approved by historic guidelines, and are a more efficient, less expensive alternative to window replacement.
Pricing for Indow inserts will depend on the size of your windows and the grade type of your inserts (we have 7 different offerings). These will range from an average of $27-$36/sf, compared a vinyl window averaging $66-$87/sf and a wood window averaging $71-$109/sf! At a fraction of the price, this is a great solution to bring comfort and quiet to your home. To receive a free estimate, we will just need the width and height dimensions of your windows.
“I couldn’t be happier, I’m so pleased with the cost and the window cleaners got confused when they couldn’t touch the glass because you can’t see they’re there. I love them so much.” – Gerry Rice, McKinney, Texas.
Each insert has a tube that edges the clear acrylic. This tubing should blend into your window frame. It comes in three colors: white, brown, and black.
All our acrylic interior storm windows are durable, lightweight and made to blend seamlessly with the surrounding frame. Don't buy new windows. Make the ones you have just right with our precision measuring software, which will ensure a tight fit for your new window inserts. Just choose the grade you need and get started measuring. We're here to help at every step.

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.
