How Do I Soundproof my Windows?

Actually, with one of our windows, it’s a piece of cake.

Soundproof Windows has been in the soundproofing game for a few decades, and because of this, we’ve pretty much mastered our soundproofing technology. We tried and failed, worked with a variety of technicians (what great things don’t come with failure?), but eventually, reached our perfect patent to answer the question, “How Do I Soundproof My Windows?”

So, what is it? Well, we can show you, here, but we’re happy to explain it. Soundproof Windows does not remove or replace your existing windows, and that was the goal. We wanted to create a product that was easy to install, easy to operate, and of course, functional. We know our customers were already annoyed by the noise, fiddling with a window to stop it all that was overly complicated would have just sent everyone over the edge – it did for us anyway while we were fiddling with prototypes.


Anyway, we found out that windows and doors were the noise problem, plain and simple. It wasn’t coming from the walls, or otherwise, windows and doors were the culprit, so what did we do? We developed an easy-to-use soundproof window installation, as well as soundproof door (sliding glass or our studio doors, if you’re a rocker or maybe a yogi), and started explaining our findings to people using STC ratings.

For many, STC Rating is a term they’ve never heard before or didn’t know it was associated with sound, but it is. The maximum amount of noise is stopped by Soundproof Windows and we have the tests to prove it.

Our tests show up to, if not higher, than an STC of 53 after installing Soundproof Windows. We know we can get STC ratings in the 60’s. Present us a noise problem requiring higher STC ratings and we will create the window that can solve it! We’re confident in that.

An STC Rating is a Sound Transmission Class rating. The STC rating is the average amount of noise stopped at 18 different frequencies, measured in decibels. STC ratings are on a logarithmic scale similar to the earthquake Richter Scale, which means each number is significantly higher than the one before.

Basically, STC ratings are an established way to average how much sound is stopped by something. STC ratings are used for windows, doors, walls, and most building materials. For windows, STC ratings range from 18 to 38. (See above, how we get in the 50s, even 60s.)

*An increase from 28 to 38 means 90% of the noise is reduced. A change from 28 to 43 represents a noise reduction of over 95%. Small increases can mean a lot of extra noise reduction. The increase from 38 to 43 mentioned above does not sound like much (90% versus 95+% in reductions) – but going from 90% to over 95% means that 60% of the remaining noise was removed; every number represents a large amount of noise*
