Energy Efficient Window Manufacturer Explains How a Good Window Can Promote Noise Reduction

Intus Windows, a leading manufacturer of noise reducing windows, says noise reduction is important for quality of life in commercial and educational buildings.

Online PR News – 14-September-2015 – New York, NY – According to Aurimas Sabulis, managing director of Intus Windows (, a worldwide leader in the manufacture of energy-efficient window products, unwanted outside noise can occur in buildings situated near highways, airports or even residential settings with barking dogs and lawn mowers. Sound problems can have a significant impact on the enjoyment of a home, but it can also have an impact on the way we work and learn.

“Windows are one of the biggest culprits in allowing noise to get into a structure, whether it is a residential home, a commercial building, or a school,” Sabulis says. “Single glass panes and wood window frames are generally the least resistant to noise. Conversely, a well-designed window can reduce noise and help create a more peaceful interior space.”

One of the most important elements for reducing sound penetration in windows is glass, according to Sabulis. Double glazed windows and a well-designed vinyl frame can help reduce noise infiltration, he explains.

“Another suggestion for reducing noise,” he says, “is to keep noise producing equipment such as generators and AC units away from windows and doors whenever possible.”

According to Sabulis, Sound Transmission Class, often referred to as STC, is used as a measure of a window’s ability to reduce sound. Generally, the higher the STC rating, the better sound control you can expect from a window and presumably the quieter the structure.

The typical STC rating of a single pane window is between 18 and 20, he says. By comparison, a typical double glazed window has an STC rating between 28 and 32.

“Some of our Intus windows,” he says, “have an STC rating of 45, allowing for exceptional sound control.”

While quality windows can be used as a sound barrier for outside noise, design factor is a major element to consider, Sabulis explains. The amount of space between panes of glass is called ‘airspace’.

“The closer window panes are to each other, the smaller the airspace and the more sound will pass through,” he says. “In addition, panes with varied thickness, rather than uniform thickness, help block sound transmission.”

These windows, Sabulis says, can decrease outside noise by up to 90 percent, as well as increase a home’s comfort level. They are also perfect for schools, hotels, and buildings in high-traffic areas.

“Our Intus windows have become the number one choice for school buildings across the country,” Sabulis says, “because it is a proven fact that noise reduction increases productivity and a student’s ability to learn.”
