Clear Acoustic Panels for Windows
Enjoying the natural light through your window does not mean you have to sacrifice sound performance. Clear acoustic panels made by Indow are a simple and easy way for you to reduce sound coming in or out of your home.

Acoustic Window Insert Features
- High grade acrylic that has a higher transparency rating than glass
- Low profile design that blends in with your existing window
- Lightweight for its product class
Types of Soundproofing
First, a disclaimer: you can’t completely soundproof a space as long as there is air. Anywhere air goes, sound goes too. Check for air quality solutions while adding soundproofing to a space.
There are two main types of soundproofing:
Sound reduction, which stops sound from entering a space. Sound reduction will help keep your space free of outside noises such as weather, outdoor conversations, and traffic.
Sound absorption, which stops sound already inside a space from echoing and reverberating.

How Our Window Inserts Work
Soundproof window inserts fit onto existing windows to air seal. They are made from high-grade acrylic to both reduce and absorb sound.
Our Standard Grade inserts block sound by 50% and our Acoustic Grade inserts block more than 70% when placed over operable single-pane windows. When placed over operable double-panes, Acoustic Grade inserts reduce noise by up to 12 dBA – that’s more than a 50% reduction in noise and an STC rating of 42 to 45.

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
