Ultra™ & WoodClad™ Series Fiberglass Windows

Beautiful to look at ---- with little upkeep required, Ultra™ Series fiberglass windows are built to last. Through a careful design process, Milgard introduces a window more resistant to heat, bugs and rot to help withstand the harsher sides of Mother Nature. A WoodClad™ Series option offers the warmth of a wood veneer interior.



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

Customization options

A Frame for all Seasons

Ultra™ & WoodClad™ Series windows and patio doors stay true through almost any environment. Because it's 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, reduces the chance for seal failure while allowing for a clear, fog-free view.

WoodClad™ Series

All Ultra™ Series windows are available in WoodClad™ Series. The WoodClad™ Series option offers the benefits of fiberglass with the warmth of wood veneer on the interior. Milgard WoodClad™ Series windows feature the look of furniture-grade Douglas Fir without a nail hole or staple on them.

Seal with a clear sealant or stain the veneer to match existing woodwork. Choose from a palette of rich, deep colors for the exterior frame to express your unique style.

Glass Breakage Coverage

Ultra™ & WoodClad™ Series windows are designed to be worry-free.

In addition to Milgard's standard Full Lifetime Warranty that includes parts and labor, Ultra Series/WoodClad Series windows come with glass breakage coverage for added peace of mind.
