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.
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.

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
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.
