When unwanted noise from the outdoors invades your home, it can feel anything but peaceful. Old, leaky windows or builder-grade windows can allow the noise from your street, heavy equipment, airplanes, and barking neighborhood dogs to permeate your home interior, making it tough to relax and hard to sleep.
Your home was meant to be an oasis where you can reboot, unwind, and enjoy family and friends. And Andersen Windows replacement windows can reduce noise infiltration in your interior so you can enjoy a stress-free, restful atmosphere. Let’s dive into how this is accomplished!
What Does Soundproof Windows Mean?
Sound penetrates homes through leaky window seals and gaps in window frames. Soundproof windows are engineered with noise-blocking features that help create a more relaxing indoor atmosphere in your home. Noise-reducing windows don’t block all outdoor sounds, but they increase your home’s sound resistance, lowering the amount of noise pollution you hear from trains, highways, and more.
Effective noise-lowering windows are made with a variety of features that slow the transmission of soundwaves. Noise moves quicker through solids than air, so you want multiple barriers included in your new windows that inhibit soundwaves from invading your home.
How Replacement Windows Decrease Noise Intrusion in Your Home
1. Thicker Glass to Combat Outdoor Noise
Manufacturers engineer windows to be more sound-resistant by making the glass thicker and using laminated glass. Your roof, walls, insulation, and windows all contribute to lowering noise infiltration in your home, and the thicker your window glass, the greater your home is shielded from unwanted sound pollution.
2. Gas Spacers Between Panes
When you have double-pane or triple-pane windows installed with noise decreasing features, gas is placed between each pane, improving energy efficiency and lowering noise infiltration in your home. Gas like argon or krypton can help muffle or cushion soundwaves, making your house a more peaceful place to be.
3. Multiple Glass Windowpanes
While single-pane windows were popular years ago, today’s modern window systems deliver more protection from outdoor noise with double- or triple-panes, decreasing the amount of noise that can infiltrate your house. Think of each pane as another layer of protection from the outdoor noises in your area. While single is good, double is better, and triple is best if you’re desiring optimal shielding from noise pollution.
The Added Perks You Get with Windows That Lower Noise Infiltration
When you decrease the noise that can permeate your home through your windows, you get the added bonus of lower energy costs. The extra layer of protection will help insulate your home from outdoor temperatures, so you won’t need to use your heating and air conditioning unit as often (lengthening its lifespan!), saving you on utilities each month.
Decreasing noise infiltration in your home can also help fix the problem of window condensation. With double- or triple-pane windows, you’ll seal the air gap between your glass panes, lowering the amount of condensation on your windows.
