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
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 outside noises such as weather, outdoor conversations, and traffic.
Sound absorption, which stops sound already inside a space from echoing and reverberating.

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.
