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.
We produce our own vinyl formula and extrude the vinyl components ourselves to ensure quality. The result is a structurally strong vinyl frame with optimized insulation performance that is weather resistant.
You may only need Quiet Line Series for the noisiest part of your house, so we designed these windows to complement our Tuscany® Series and Montecito® Series product lines which provides a uniform look throughout your home.
Milgard guarantees to the original purchaser of Quiet Line Series windows that we will replace any windows that are found to be defective in materials or workmanship during the ten year warranty period, from the install date.
