Window Soundproofing

At Soundproof Chicago, we help you take control of your indoor environment by dramatically reducing intrusive noise—by up to 95%. Whether it's honking horns, roaring trains, low-flying airplanes, or loud conversations from nearby neighbors, you deserve a space that feels truly private and serene.

Most people don’t realize that standard windows and sliding glass doors are the biggest culprits when it comes to letting outside noise inside. Unlike your walls, which offer natural insulation, windows are thin, unsealed, and poorly constructed for sound control. That’s where we come in.

Window Soundproof FAQs

How do soundproof windows work?

Our soundproof windows do not require you to replace or remove your existing windows. They are custom designed and fabricated to match the look and function of your existing windows while creating an effective barrier against noise. Adding a secondary window is by far a better solution than replacing your existing windows with a “soundproof replacement window”. Our windows are made from aluminum frames, and laminated glass in different thicknesses depending on your specific noise problem.

How much noise reduction can I expect with soundproof windows?

Overall noise reduction depends on a few factors; the type of noise, your proximity to the noise, and the construction of your exterior walls. When dealing with street or highway noise, we can reduce the noise by 75-95%. If you live next to the elevated rail or freight train, we can reduce the noise by 50-95%, Airplane noise can be reduced by 75-95%. Again, there are a few factors that come into play when dealing with exterior noise. If you contact us with a description of your noise problem, one of our soundproofing experts can let you know how much reduction can be achieved.

Are there more benefits to adding soundproof windows?

In addition to their ability to block sound, there are more benefits to adding soundproof windows. Since our windows double as an interior storm window, most of our clients notice a difference right away in the amount of heat, cold, dust and draft that enters their home. To be exact, our windows block 99% of dust and draft. Pollutants and allergens will be greatly reduced if not completely eliminated as well.

How do I know my windows need soundproofing, and not my walls?

Noise travels the path of weakest resistance. Of all the materials your house is constructed from, whether your home is wood frame, or brick, the windows are the weakest part of the wall and should be addressed first when dealing with exterior noise. A typical window’s primary function is to block elements like heat, and cold; not sound. In most cases, our soundproof windows are all it takes to remedy the noise problem. In some cases, walls may need soundproof treatment.
