Frequently asked questions

Do soundproof windows work?

Soundproof windows can block up to 90 to 95% of sound transmission. They are more effective in blocking sounds with higher frequencies than lower ones. High-frequency sounds include birds chirping, whistling, glass breaking, and some voices. Low-frequency sounds include diesel engines, airplanes, or thunder.

Can any soundproofing methods block 100% of the noise?

There are currently no residential windows that can block all sound. Instead, a material's noise-reducing effectiveness is indicated by its sound transmission class (STC) rating. The higher the rating, the more effective the window is at blocking sound.

An STC rating of 25 indicates no soundproofing, while a rating of 65 indicates complete soundproofing.

A standard, non-soundproof window has an average STC rating of 26 to 28, while ratings for soundproof windows range from 48 to 54.

Are soundproof windows energy efficient?

Soundproof windows with specific features can provide energy efficiency:

Efficiency of soundproof windows
Feature Benefit
Laminated glass Laminated glass blocks 99% of ultraviolet rays, decreasing the heat they cause and lowering air conditioning costs.
Frames Well-built frames stop air from entering or exiting through or around the window.
Low emissivity (low-E) glass Low-E glass has a thin, transparent coating that reflects energy. Instead of hot/cold air leaving through the window, it hits it and bounces back.
Spacers Spacers separate each pane of glass and insulate the edges, helping to reduce the transfer of heat from inside to outside and vice versa.

Is it better to install new soundproof windows or soundproof existing windows?

Soundproofing existing windows is typically cheaper than installing new windows. Most of the materials are less expensive, and many of the options are DIY-friendly. However, these solutions may not be long-lasting or as effective as replacing the entire window.

Replacing current windows with entirely new soundproof ones can be a costly upgrade. Yet, they are a long-term solution for blocking out noise and often have the added benefit of making the space more energy efficient.

Getting quotes from soundproof window installers

Consider the following when choosing a professional window installer:

  • Decide between replacing old windows vs. soundproofing existing ones.
