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 vinyl window averages $66-$87/sf. A wood window averages $71-$109/sf. With Indow inserts averaging between $31-$44/sf MSRP, your window project can cost a fraction of other options.

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.

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.

How Much Do Indow Window Inserts Cost?

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.

    Excellent product, support, and very clear instructions. We look forward to installing these on all our windows.

    I ordered the "acoustic grade inserts" for my bedroom to reduce road noise. They work exactly as advertised. Are they soundproofing? NO. Do they reduce noise to acceptable levels? YES. Compared to other solutions on the market (replacement windows, glass inserts etc) this is much more affordable. However, if you are looking for actual soundproofing, you need to spend more money and get something else. As a bonus, the inserts are tight fitting and have reduced drafts.

    We have single pane historic windows in our house in Newport RI. I was looking for a great solution to both temperature and noise. I decided to try the acoustic indow product.

    I am thrilled with the process and the product. James from Indow was super helpful in answering questions. The laser measuring kit was easy to use and gave you confidence in your own measuring ability as it checks your work. The 4 indow products i ordered came well packaged and were easy to put in.

    Finally, the indow inserts look great and work great. We can no longer hear every conversation outside and the birds don't wake us up every morning. My wife didn't even know they were there. They blend in and can't see them unless you look.

    I highly recommend these. More cost effective than custom storm windows, they look better and you can easily install or remove them as you need.

    Fantastic product and service.

    Indow has established the complete breadth of custom service, from initial enquiry to being very responsive to "after-sales" questions. Ours was and out-of-the ordinary project involving casement windows in a solarium and the end result turned out quite perfectly. Access to information online, instructions arriving with the delivered windows, and answers by phone insured we "enthusiastic amateurs" completed the job to satisfaction.

    I am very pleased with my Indow window inserts. I have a very old house and am near a busy road. I wanted to reduce the noise. I've just installed them and find a considerable reduction in traffic noise. They definitely were worth the cost. The measuring process is quite detailed but easy to follow and my inserts fit perfectly in crooked, 265 year old openings. The company representative Hannah Hendrickson

    was very professional, knowledgeable, and courteous. I highly recommend the Indow

    company.

    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.

  • 5 Stars ⭐️⭐️⭐️⭐️⭐️

    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!

    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.
