Reducing Outdoor Noise With New Windows

Published on

Nothing can be more annoying than the dog barking next door or a lawn mower running, especially if you are trying to have some quiet time for yourself. Whether you live in the city itself or the suburbs, outdoor noise can be a problem. Fortunately, there are ways you can deal with the issue, one of which involves a new window installation.

The Windows’ STC

Like other building components such as the wall or ceiling, windows are rated with a sound transmission coefficient (STC). This measures the ability of a material to block sound waves. The windows’ design and installation are two vital factors that affect their STC.

Typical double-pane windows have an STC rating of about 28 to 32, provided that they have 2.5-millimeter single-strength glass. The higher the STC value, the better the windows are in blocking sound waves. Airports and other areas with high noise levels often have windows with an STC rating of up to 40.

Energy Efficiency Is the Key

As it turns out, excellent acoustic control coincides with high energy efficiency. The air in which sound travels is the same one that makes the indoors uncomfortable. Selecting energy-efficient casement windows not only lowers energy costs but also provides the added benefit of less noise intrusion.

During installation, the pros must use high-quality weatherstripping on the frames and sashes to reduce the infiltration of sound, as well as dust, moisture, and air. Taking the thickness of the glass into account is also important. Different thicknesses create different vibrations that deflect sound waves.
