Quiet Line™ Sound Control Windows

Noise pollution is a fact of modern life. But that doesn't mean you can't give clients quiet homes even in noisy locations. One solution is Milgard® Quiet Line™ insulated windows.

Poorly performing windows are a major culprit when it comes to exterior noises making their way into a home. Sound transmits through vibrations that spread out in all directions and penetrate wherever there is air space. Many sound-reducing glazing systems are rendered ineffective if there are air leaks around the glass or frame.
