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:

Sound Reduction

Sound Absorption

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 Reduction | How to Increase Sound Absorption |
---|---|
Seal gaps in window (caulk, weatherstrips) | Add furniture |
Sound-dampening curtains | Hang acoustic panels |
Install sound-reducing blinds | Lay plush rugs |
Install interior storm window inserts | Purchase 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.

*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.

Working with Indow has been a great experience from start to finish. They answered all our questions & guided us through the whole process. We ordered 15 inserts & they have reduced the Highway noise that we were experiencing after buying our house. A great product & innovative company.

I live 20 feet from a busy road with lots of trucks. We almost didn't buy the house because of the noise. my house is the perfect candidate for indows. After installing them (myself. .. directions were so easy) we can barely hear any trucks noise at all. Indies live up to their claim and has made a huge difference.

I am very pleased with the noise reduction and heat-trapping effects of my Indow inserts. I bought three small inserts as an experiment for the noisiest part of the house all year round, and where it's cold in winter. They have done beautifully well in sealing out both noise and heat. My only issue has been to get one of them installed perfectly straightly on one side, but it was done in a difficult location and isn't that important. They are also quiet expensive, but I may get a federal tax rebate on them.

It could have been better if the pallet was collected after the delivery. Also the inserts are more beneficial for picture/fixed windows rather than open windows. The price of insert are expensive.
Larry S
I was pleasantly surprised how well the appearance after installation, perfectly clear, plus reduce the noise from the outside more than I expected. I would definitely recommend anyone looking for noise reduction to consider these. I will be purchasing more as time goes on, thank you Indow

Called about price $1000.00 For 2 small windows asked about energy savings? They said no guarantees depending on location and almost other factors, why would I spend that money w no guarantees
Christie R
It has cut down noise tremendously and is definitely more efficient with keeping our cooling in and heat out this summer.

Indow is a trendsetter in eCommerce. They make the entire process of ordering, purchasing, and installing their product very easy for any walk of life; and, their communication processes are excellent. The inserts I purchased and installed were just as described. They are effectively blocking soundwaves, but not vibration, which was discussed during my initial call with an Indow Representative. I would recommend Indow window inserts to a friend.

Our window inserts have decreased road noise in our bedroom by 75 percent which we are very pleased with. The whole process was extremely simple and organized. Everyone we dealt with was professional and helpful. The inserts were simple to install and I would recommend to others.

They make it easy to measure and install and it does reduce the noise as I live next to a busy highway. I am happy with the purchase.
Ivan L
We have a multi-story building construction next block that starts at 7 a.m. daily and a busy street a few blocks away. Before the insert was in place in our bedroom, we heard every piece of construction equipment there, including the obnoxious beeps from vehicles backing down in the lot, and all of the emergency vehicles passing by on the avenue. Now, this sounds like something happening twenty blocks away, barely noticeable. This is a huge quality-of-life improvement from day one of the insert installation.
Stan B
All fit as planned and are good
Cassie M
Overall very easy process from ordering to install. Was just hoping that the sound dampening would have been a little better.
Dan C
Effective and frequent communication from Indo Window starting with the order process, through production and post-delivery. The insert fit was excellent, fitting snuggly. The panel is quite effective in reducing noise. My wife was sleeping in the basement due to traffic noise. She is able to sleep in her bedroom again. Overall an excellent experience!
Lynett P
Great product. Arrived a bit dirty.
