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.
Adding Indow inserts to an existing window can make your windows perform as well (or better!) than a replacement window, but at a fraction of the cost and without the hassle and disruption of installing new windows.

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!

Constant traffic noise made it hard for this family to sleep and almost forced them to move before they found Indow inserts.
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.

Our air-tight seal not only keeps noise out and your ideal temperature in, but it also reduces condensation and blocks dust, pollen, and other airborne particles.

These windows are great! They have improved the quality of our home with reduced thermal loss and reduced noise level! The temperature today is 93° outside, our split system is set at 73° and the inside house temperature is 74°! Before the install of these windows the inside temperature with these conditions would have been 76°! Last night I noticed an ambulance going by. Normally the first thing I recognize is the noise, but last night I didn't realize it was an ambulance until I saw the flashing light! Hannah did a wonderful job coordinating the measurements and the sale! I would recommend these windows to anyone!
