Picking the Right Noise-Reducing Window

There are three things homeowners prioritize when selecting replacement windows or entry doors: beauty, energy efficiency and noise reduction capabilities. In today’s post, Renewal by Andersen® of San Antonio discusses the importance of noise reduction when it comes to windows and how the right windows can make your home a more peaceful environment, thus improving your quality of life.

Picking the Right Noise-Reducing Window


How Does Noise Reduction Work? 

To a certain extent, your entire home—including your windows, patio doors and walls—blocks outside noise by serving as a barrier between the sound waves and your ears. Your home can’t completely block all outside noise, however, which is why noise-reducing windows are important.

There are three ways window manufacturers enhance the noise-reduction capabilities of a window: by increasing the glass’ thickness, increasing the space between window panes or using laminated glass, which has a plastic layer placed between two panes.

STC Rating System 

Fortunately, you can easily gauge a window’s noise-reduction capability through the STC (Sound Transition Class) Rating System. A window’s STC value gives you an idea of its noise reduction capabilities, with a higher STC Rating indicating better noise reduction capabilities. To get the most value out of your money, you should pick a window with an STC rating that’s equal to or higher than the typical value for its type. For single- and double-pane windows, pick one with an STC value of at least 27 and 26, respectively.

If you’re looking for a stylish, energy-efficient window with above-average noise-reduction capabilities, it’s worth considering Renewal by Andersen’s 400 window series. The series’ impact-resistant High-Performance™ Low-E4® glass has a PVB interlayer that blocks sound waves. And with an STC value of 34, the 400 series is well within the upper range of double-pane windows when it comes to noise reduction.

"If I could heap more praise on Renewal by Andersen, I would have to buy a dump truck. They recently replaced 13 doors in my home in an exemplary fashion. Very professional, efficient and, in my estimation, worth every penny."
