Soundproof Your Home: Window Inserts & The Basics

Soundproofing windows depends on how sound is coming into your home and what noise is disturbing you. Soundproof windows work against traffic noise, barking dogs, & noisy neighbors – and they do this with window insulation. Soundproofing window inserts provide inside window insulation that both reduces and absorbs sound. Find out if they'll work for you:

Types of Window Soundproofing

Sound Reduction — Decreasing noise from its original level by blocking it. Sound-reducing products prevent noise from entering a space.

Sound Absorption — Decreasing noise from its original level by stopping its movement within a space. Sound-absorbing products stop noise from bouncing off surfaces.

How to Increase Sound ReductionHow to Increase Sound Absorption
Seal gaps in window (caulk, weatherstrips)Add furniture
Sound-dampening curtainsHang acoustic panels
Install sound-reducing blindsLay plush rugs
Install interior storm window insertsPurchase plants

Now that you know the difference, decide whether you need sound reducing or sound absorbing products.
Don't know which product you need? Noise generated outside calls for sound reducing products to stop noise from traveling through windows, ceilings, doors, and walls. Noise generated inside requires sound absorption products to reduce echo.

If outside noise is your issue, Indow is here for you. Noise travels via vibrations in the air and insulating, air sealing inserts block that noise from entering your space. Can't decide? You may need both.

Indow products can be used to block outside noise from entering while sound absorbing materials inside can minimize reverberation. Keep in mind, sound reducing products, like inserts, will provide a more noticeable difference in noise than sound absorbing products.

How to Soundproof a Window with Inserts

Installing window inserts is an easy and effective way of soundproofing windows. Indow Acoustic Grade window inserts can reduce and cancel noise – up to 70% of outside noise when placed over single-pane windows and up to 50% of noise coming through double-pane windows. In an office or home, soundproofing windows is easy with our inserts that press into your existing window frame—no hassle, nails, or adhesives required. But how much does it cost to soundproof windows?

Indow inserts are edged with silicone compression tubing to create a seal for your soundproof window. Getting an exact fit is essential in soundproofing a window, since gaps and spaces allow sound to seep inside. This precise fit also creates a more comfortable, energy efficient space while the low profile practically disappears into your window frame. Our custom-made inserts offer simple soundproofing for any window shape.

Watch this 2 minute demo by window expert, The Craftsman Blog:

*We want to ensure our inserts help solve your noise problem. Overall noise reduction depends on the amount of noise coming through your walls, ceilings, floors, doors, and existing windows. Noise reduction will be less when placed over double-pane windows. Read our full Noise Reduction Sheet to learn more.

Sound Absorbing Treatments

Despite your best room soundproofing efforts, the sound that does penetrate can be absorbed once it's in the room to minimize reverberation. It's best to avoid minimalist style of exposed brick and wood floors. Consider hanging Acoustic panels. Also, plush rugs with sound dampening rug pads, wall hangings, upholstered furniture and plants will help absorb sound.

    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.

    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.

  • 5 Stars ⭐️⭐️⭐️⭐️⭐️

    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%.
