HIGHLIGHTED REVIEW

We replaced 31 windows of various types with Milgard Ultra products and have superb noise and harmful ray reduction. They open and shut with the precision of a bank vault and are clearly built to last a very long time. The physical strength was important to our selection and we are well satisfied. Our house has received numerous compliments regarding both inside and outside appearance. - Seattle, WA

A Frame for all Seasons

Ultra Series windows and patio doors stay true through almost any environment. Because it is made from glass fibers, the frame expands and contracts at approximately the same rate as the insulated glass it holds. This puts less stress on the seals, reducing the chance for seal failure while allowing for a clear, fog-free view. 

Ultra™ Series Frame Colors

Milgard Ultra™ Series fiberglass window frames come in a palette of rich, designer colors. From warm 'harmony' to bold 'black bean', get inspired with all 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.
