How Do They Work?

The air gap that is created between the soundproof window insert and the existing window produces an insulated sound trap, where sound waves are absorbed, reflected and cancelled. The result is a much lower volume of sound that makes it through the sound trap into the room. The air gap also reduces energy loss by 60% per window.

The seal of our soundproof window inserts is important because sound can act like water, seeping through openings. Our infiltration rate is less than .01 cfm/lineal foot, which far exceeds the International Energy Conservation Code (IECC). Please note that "soundproof" drapes or curtains typically do not have a seal around them, allowing sound to enter the edges of drapes or curtains unabated.

PRICING & INSTALLATION

Soundproof Window Cost

Our soundproof window cost depends on your number of windows, sizes, shapes, window treatments and ease of installation. Residential soundproof window inserts usually cost between $22 and $58 per square foot, including installation and tax. For example, buying three six-foot by three-foot inserts costs approximately 25% less per insert than buying one. Arched windows are about 15% more expensive than rectangular windows because they take more time to cut and install.

Prices for commercial soundproof window inserts vary even more (both lower and higher). For example, having more, larger windows will lower the cost of each insert; however, having windows that are difficult to access will raise installation costs. Our hotel installations are a good example of this – they have many large windows, yet limited access to rooms.

Installation and Timing

In most cases, we can install your soundproof window inserts within two to three weeks of receiving your 50% down payment. We usually install in one to two days, depending on volume and accessibility.
