Arched Windows? We’ve Got You Covered.

Specialty shape inserts for the arched, round and otherwise odd-shaped window.

Acrylic opens up all kinds of possibilities. It’s lightweight, more transparent than glass and can be made into just about any shape imaginable. Which is why people with odd-shaped windows, from arched windows to those resembling batwings, have sought us out to make them interior storms.

Often people with unusually-shaped windows didn’t think they were ever going to be able to block drafts on that funky little round window on the second-floor landing.

And then they found us.

How do we make custom-shaped window inserts?

We ask people to make a template by tracing their window onto paper. Tyvek is the best, because it’s strong and light still shows through. On occasion, people will trace their odd-shaped windows onto tissue paper, but that’s prone to ripping. We don’t always need a template. Every window is different – we just try to keep the process as simple as possible.

Here’s a picture of our Operations Manager Brianna, reviewing some window templates on our conference room floor.

After we trace the shape onto acrylic, we use a circular hand saw to cut it.

The circular saw cuts in small straight lines, kind of faceting it a little like a diamond. Then we sand that edge smooth, forming it into an arch or round, or the dips and peak of a window that resembles a fancy badge.

This is a big departure from most of the inserts we make. For normal rectangular window inserts, we input measurements into a software program that tells our Computer Numeric Control (CNC) machine how to cut the acrylic.

Also, for normal, rectangular window inserts, we use a rigid ABS (Acrylonitrile Butadiene Styrene) plastic carrier with a silicone edge. But that won’t work for shapes that dip, peak, half-round and full circle!

For custom-shaped funky windows, we have to use pure silicone tubing all around the edge, like we used to for all inserts in the old days (which was just a few years ago!) It bends and molds nicely to the edge of round window inserts.

Some other shapes we can make inserts for:

  • Half-round
  • Oval
  • Gothic
  • Eyebrow
  • Bell-top

Indow vs. other odd-shaped window solutions

It’s hard to find companies that make exterior or interior storms for odd-shaped windows. It’s labor-intensive to craft them of metal or wood, which makes them expensive. Plus, they’re hard to remove and put in.

“People are just generally surprised to find we do it at all,” said Brianna. “A lot of companies don’t. People tend to be surprised by how nicely they fit. They disappear into the frame.”

    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.
