Around nine-tenths of outdoor noise passes through a home’s glass rather than doors, roofing or walls. These sounds can become particularly bothersome if you live near a highway or airport. Many homeowners have to listen to neighbors’ lawnmowers, dogs, and loud parties from time to time. Fortunately, new windows can significantly reduce noise.
Multiple Panes
While older units may only have a single layer of glass, a replacement window typically has two or three layers. It’s harder for external sounds to pass through multiple panes. Some models provide better results than others; the distance between and thickness of the layers holds importance.
Tightly Sealed
Plenty of noise can travel through a tiny gap. New sashes shut more tightly than old wooden units. Likewise, the frames and individual panes are well-sealed. Locks work correctly, the glass is free of cracks, and the upper sash doesn’t slide down on its own. This saves energy while preventing the infiltration of pests.
Soundproofing
You’ll benefit from even more significant noise reduction if you purchase the latest acoustic or soundproofed windows. These products use lamination, heavy glass, and thick sashes to absorb around 70 to 95 percent of outdoor sounds. The downside is that they cost far more than conventional replacements.
More Privacy
If external noises can pass through your glass, indoor sounds probably do the same. New windows maximize privacy, making it harder for someone to overhear your conversations. This is a good reason to replace old units if you live within feet of a sidewalk, parking lot, or building.
Basically, new windows reduce noise because they’re tightly sealed and contain at least two layers of glass. Some models are designed to block louder sounds than others. However, it’s only possible to gain these benefits if you use well-made windows and install them correctly. Be sure to hire an experienced professional contractor.
