Ultra™ Series Windows

The Ultra™ Series, as the name implies, is the ultimate window frame material for new construction and fiberglass replacement windows.

Because it's made of glass fibers, it expands and contracts at the same rate as the insulated glass it holds. This puts less stress on the seals, reduces the chance for seal failure and results in a clear, fog-free window that lasts for years and years.

Milgard® Ultra™ Series fiberglass windows combine a traditional wood-frame profile with the strength, stability and low maintenance of fiberglass. Our fiberglass windows withstand the harsher sides of Mother Nature like no other window, yet look like traditional painted wood windows. In fact, you can choose any of our factory-painted exterior colors or paint the exterior yourself. And for multi-unit projects, Milgard offers the option of custom colors applied at the factory. Milgard fiberglass windows are custom made to your home's exact specifications at no extra charge or extended lead time. You can customize them with our wide selection of hardware finishes and virtually endless grid options. All Milgard fiberglass windows are covered by our Full Lifetime Warranty with Glass Breakage.

Outstanding Replacement Windows I have extensively researched my window selection for over two years. The windows are in our family home in Oregon built in 1925. I wanted period correct windows down to the exterior and interior look including the new fine scalloped grids. Our home has over 40 windows and they were very drafty. Our home feels so warm and comfortable and we are very happy with how the windows have enhanced the appearance of our classic craftsman two story family home. I wished I had made the decision years earlier. I have already recommended the Milgard fiberglass windows to others. February 18, 2013
Beautiful Window We bought a home recently that had a tiny 4' wide kitchen window facing a gorgeous view. We opened up that wall and got an 11' wide x 5' high set of Ultra fiberglass windows (2.5' casement + 6' fixed + 2.5' casement, mulled together) right at counter height. It looks beautiful, is a perfect match to the existing Milgard windows, and the price was very fair considering the quality. What that view adds to our kitchen is priceless. Thank you, Milgard!

The Ultra Series windows and Patio door have greatly improved the energy efficiency in my home. The Ultra Series windows and patio door have greatly improved the energy efficiency in my home.These products replaced single glazed aluminum framed windows so there was a noticeble improvemnet in cooling and heating costs as well as improving upon the level of quietness in my home. For the 12 month period post-installation there was almost a 30% decrease in energy consumption in my all electric home. My only criticism is in the quality of the trim work on the exterior frames. I have a brown-tone exterior frame and white interior. Though the interior finishes only have minor flaws, there are several to be found on the exterior, such as excess glue leakage at the joints which dust sticks to and chipped brown tone paint on several windows and on one window about 1/4' gap on a trim piece. Overall I am happy with the windows as my goal was to improve upon the comfort level in my home which these windows have accomplished. April 2, 2012
We love our Milgard Ultra Fiberglas Windows!!! We are very glad we had Milgard Ultra Fiberglas windows installed a few years ago. They are easy to open, easy to clean, beautiful, insulate well, and we're looking forward to enjoying them for years to come. The only thing of which I know that I would change is the fuzzy strip on the inside which is white on our white windows and shows grey in places. I'd recommend making that strip medium to dark grey to begin with since it obviously won't be staying white. My parents also had Milgard Ultra Fiberglas windows installed in their house and are enjoying them, as do we when we visit! April 1, 2012
This product function properly all the time. This product keeps the wind and heat out of the house. They look nices and operates correctly all the time. We can now set in our kitchen without being roasted out by the heat.. March 30, 2012
Operation difficulties and exterior paint issues Operational difficulties - the window comes with a fold-down operator which can easily interfere and mar the interior finish of the window. The operator and operation of the window makes opening of large (3'0"x5'0") casement windows from the fully closed position and to the fully closed position (for latching) forces intensive. It feels at times as if the mechanism will fail or the handle will strip. Experior paint issues - the exterior coating for the fibeglas frame is easily scratched, chipped or scuffed revealing the white fiberglas underneath. We have been unable to get a "touch up kit" to recover these issues. Having these these issues addressed for the next generation of windows would make them superlative. April 3, 2012
great windows I bought 27 windows for my remodel. They were put in by a contractor while I was away. Was bummed with a couple. The corner seams were a little sloppy. Had I noticed before I would have maybe asked for replacements. But overall I like them. March 31, 2012
