Superior Sound Control

Sound Transmission Class (STC) is a rating system used to communicate how well a product blocks sound. A typical double glazed window provides an STC rating of 28-32. Quiet Line Series can provide a rating of up to 48, for superior noise reduction. Talk to your Milgard Certified Dealer about all noise dampening options.
