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 To Get A Custom Specialty Shape Window Insert
First we'll help you determine if inserts are the best solution for you. Next, we'll guide you step-by-step through measuring & tracing your odd-shaped windows and then custom-cut your inserts for a perfect fit. Get a free estimate today to discuss pricing and begin your order!
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.”

Oh, and did we mention that these odd-shaped windows come in all our grade types, from Privacy to our UV-blocking Museum Grade? Check out our product pages to customize your order.

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.

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.

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
