What does a 70% reduction in noise sound like? Listen to how much the music is reduced even from inside the window!

Windows (even double paned) are notoriously bad insulators - especially against noise. Whether its dogs barking, cars driving by, construction, or any of the other noisy nuisances we encounter in our neighborhoods, windows can make it seem like the sound is coming from inside the house.
Soundproofing your home can be a challenge. Window replacement is an option for some, but can be a very costly and intrusive process and often only reduce noise by 25%. The total costs of window replacements (including labor) aren’t a great option for increasing your home’s resale value.

*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.
Other 'soundproof' options - like heavy blinds or 'sound absorbing' curtains - will only dampen outside noise, but also block out the things your windows do best - bathe your home in natural light. This is where window inserts really shine.
WIth our patented Snug Fit compression tubing and premium acrylic glazing, our Acoustic Grade Window Inserts can block up to 70% of the noise coming through your windows. That’s about as close as you can get to soundproofing your windows without building a wall over them.
But the best part? They blend in with your existing window frames and let light flow in freely. In fact, if it wasn’t for how much quieter they make your home - you’d forget they were there!
Our inserts are custom cut to your exact window dimensions and require no modifications to your windows or window frames. With a provided laser measure device and our proprietary measurement software, you can rest easy knowing your inserts will fit snugly and create an airtight pocket to seal out sound, as well as extreme temperatures!

“After moving in, we realized just how busy the street was because it was so noisy we could not sleep at all. Neither could our infant. (The inserts) came on time and were installed so easily, I couldn't believe it! The difference in sound was unbelievable.”
