There are several options available to help you soundproof your windows to prevent noise problems like traffic and street noise and other noise pollution issues that vary in affordability.
Seal Gaps: Gaps between the window frame and wall can allow noise to enter your home. One of the easiest and most inexpensive ways to mitigate traffic noise is to seal any gaps around your windows. There are acoustic caulks available which are designed for this purpose to help reduce traffic and other street noise.
Window Inserts: These glass inserts are installed in the window frame in front of the existing glass of the window. This creates an air gap between the window and the insert to stop sound vibrations from making their way in. Window inserts are best used to increase the noise prevention of single-pane windows rather than double-pane, since double-pane windows are already designed to reduce noise.
Soundproof Windows: These windows are manufactured with very thick glass which prevents sound waves from penetrating them. They also employ the use of air space in between window panes and are typically made of several sheets of glass which has a layer of plastic or acoustic interlayers in the middle to minimize sound transmission.
Replacing your existing windows with soundproof windows is one of the most effective solutions to reduce noise, but it is much more expensive and can be a major inconvenience.
Polycarbonate Panels: DefenseLite polycarbonate noise-reducing panels can reduce traffic noise by up to 40% because they are much thicker than glass windows. These panels are a retrofit solution, so you don’t need to replace all of your windows. DefenseLite is applied on the exterior of the existing window and door glass, creating an air gap that reduces noise. However, unlike competitors, DefenseLite utilizes an engineered ventilation system to eliminate condensation and moisture buildup, ensuring the glazing stays clear.
Not only does DefenseLite create a sound barrier, but it also can slow and prevent criminals from gaining entry and improve energy efficiency. These polycarbonate panels can be installed over both single and double pane window options, and don’t require routine maintenance like traditional, more expensive laminated glass.
Soundproof glass, also called acoustic glass or soundproof glazing, isn’t cheap and varies in cost depending on the specifications. However, you can expect to spend around $950 for a double-pane laminated glass window, plus the labor needed to install it.
In contrast, soundproof polycarbonate panels like DefenseLite typically cost about $30-$75 per square foot to install. All DefenseLite panels are installed by trained and certified dealers and are covered under manufacturer warranty. Depending on the system, warranties range from a minimum of 2 years to up to 15 years.
While many people believe that they need double or triple pane, laminated glass to make their windows soundproof, the best way to reduce noise in your home is with polycarbonate panels. Polycarbonate is much thicker and stronger than glass, but still retains the same amount of visibility, so it offers a great option for noise reduction in your home, retail space, or office building.
Noise-canceling windows and sound reduction inserts may work in many scenarios, but the best solution, DefenseLite, also offers security and insulation. It provides a nearly invisible layer of protection that can reduce noise by up to 40%.
Generally, the thicker the glass, the more noise reduction. Since soundproof windows typically have two layers of glass in them, each one can vary in thickness depending on your needs and the source of the noise. Additionally, the air gap between the two panes of glass can also vary in thickness, increasing the window’s overall noise reduction. Typically each pane of glass will fall between ⅛” and ¼” thickness.
DefenseLite polycarbonate is ⅜” thick, but it is applied on the exterior of existing windows and is nearly invisible upon installation. Since our polycarbonate is so thick, in many cases it offers superior noise reduction over thinner glass solutions.
