Just had Quiet Line window installed in our bedroom that faces busy road in The Woodlands, TX. Window significantly reduced the noise, enough that I no Ionger have to run sound machine or house fan to block the noise and can sleep soundly. Very happy with window. I was concerned about how double, double pane window would look, but it looks fantastic. I looked for several years for the best solution for the traffic noise and glad I picked Milgard. - The Woodlands, TX

Combinations and Mulling

All Milgard windows and doors are built to your specifications. So while we're showing a few sample combinations, there are literally hundreds of products to combine and ways to combine them. A Milgard Certified Dealer can help you explore the possibilities.


Energy Calculator

The Milgard Energy Calculator provides a quick and easy way to help you select windows and doors that can meet local energy codes and project requirements. This tool gives you the flexibility to select the required ENERGY STAR® zone, u-factor, SHGC or VT, and determine which Milgard window and door products meet the selected requirements. Additional selections can also be made based on product series, operating style, glass type, grids and spacer type.

Engineered for Superior Sound Control

Every Quiet Line Series window is double glazed with a built-in sound panel, essentially two windows combined into one. But rather than gluing together two separate components, we carefully design each quality window through single-extrusion construction for superior sound control and better weather protection.  

Sound Transmission Class (STC) is the main rating system used to communicate how well products block sound. A typical double glazed window provides an STC rating of 28-32. Quiet Line Series can provide a rating of up to 48 --- better protecting against the noise pollution that may keep families up at night. 

Designed to Complement Other Vinyl Lines

While developing the components that contribute to the performance of Quiet Line, we were also sensitive to the design. When you install Quiet Line Series, you're probably only doing so for the noisiest part of the house. To keep a uniform look throughout, you can match Quiet Line with the window styles from Montecito® Series and Tuscany® Series.
