Indow Pricing
Indow window inserts block drafts, reduce noise, and save on your bills. We've made tens of thousands since opening for business, and we're proud to offer a premium, custom-made, & high-performance product for an accessible price.
Indow pricing is by the square foot and the grade type you select. Indow makes three high-performance window insert grade types. Each provides special benefits and all press into place without the disruption or added cost of construction.
What Do They Cost?
Consider the cost and disruption of replacing your windows. A
Standard Grade
$31/sf or just $372 for an average window
Our workhorse interior storm window insert blocks drafts and reduces outside noise.
Performance Grade
$40/sf or just $480 for an average window
Our 4 options in performance grade inserts provide superior protection against noise and light.
Commercial Grade
$44/sf or just $588 for an average window
Industrial strength inserts with a scratch-resistant coating can be cleaned with common products.
When you measure your windows, you’ll have help at every step. First, we have a library of video and written tutorials available. Second, our amazing team is always ready to take your call if you need assistance. Third, our proprietary measurement software will automatically check your measurements as you enter them to ensure a tight, snug fit for your custom window insert.
*Sales tax & shipping charges not included. Shipping charges vary by region and order size – talk to a Fit Specialist to get our best pricing.
Better Than Your Average Window Insert
Custom Made. Snug Fit Guaranteed.
Our proprietary technology ensures a perfect fit whether you have odd-shaped windows or out-of-square windows. Unless you have a new house, your windows aren't perfectly square (and even that doesn't guarantee it). Homes settle, and create slanted windows—even if the window looks rectangular.
This is why most “out of the box” window inserts available at hardware stores won't fit your windows. Even if they seem to, a few millimeters gap allows drafts and noise to penetrate.
Aren't They Just Plastic?
We use high-quality acrylic and silicone to build an insert that creates an air seal and has better optical clarity and thermal properties than glass. Our acrylic doesn't yellow over time, and our silicone doesn't lose its spring force—even exposed to the sun.

Indow Inserts vs Replacement Windows
- Compared to full replacement windows, Indow inserts cost on average 75% less than wood & 50% less than vinyl.
- Instead of ripping a hole in your wall, simply press an insert into place.
- Meet historic guidelines with an insert that practically disappears vs thousands of dollars on replicas.

Other Add Ons
Odd-shaped windows can be accommodated with special geometry window inserts for an added 25%.
Large windows, up to 6' x 8' or 5' x 10' do not require mullions. Windows larger than that do require mullions with the insert split into smaller panels.
Guarantee & Warranties
All window measurements are checked by our software and window experts before the first cut is made. Because of this, our inserts come with a Residential Warranty, which protects your investment for as long as you live in your home. Our Commercial Warranty protects your investment 10 years from the date of purchase. Our Snug Fit guarantee is included in all self-measure orders.
Included in your order is: a cleaning kit, care guide, & installation support with a dedicated case manager in the event of an issue.

They are working great! Very happy with the purchase.
I'm enjoying the units, however will need to wait until next year's colder weather to get a truer feel or read on how well they work - thanks
They work very well for my 3 Bedroom windows.easy to install.
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%.
Wonderful product
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!!
fit perfect, weny in easyand make a diffrence with noise ,thank norbert
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.
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
