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.

Best Windows ever! We installed new windows and a patio door unit from Milgard in our new home. They are well constructed and look very nice. Most important they are excellent energy savers. That is so important as we live in the Arizona desert. We did receive one of the windows damaged but Milgard sent a replacement immediately. Wonderful windows, wonderful company. Thank you Milgard.

Windows look great The 18 windows that our in our house are excellent, Milgard stands behind their product even 12+ years later. Would choose and recommend Milgard again. April 17, 2014
Sound reduction We purchased new windows to cut down on heat loss and lower noise levels from traffic. The Milgard Ultra windows achieved our purposes. Our home was much cheaper to heat. The noise levels were significantly reduced to a background level that was easily ignored. January 16, 2014
A strong, well made, full featured, quality product. 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. September 10, 2013
Excellent I couldn't be happier with these windows. They totally improved the appearance of my house. I had all my windows replaced; fifty total. I have single hung, casement, picture and awning. They are all fantastic! October 14, 2013
Great windows with exceptional customer service Installed 34 windows both sliders and single hung. Looks like I move to a new house. The low E glass is extremely effecient at block out the southern California heat and when these windows are closed they do a great job eliminating outside sounds. August 8, 2013
Superb performance and appearance We live in a now historically designated neighborhood in Oregon. Our 1919 Cape Cod has 53 windows on 3 stories. The windows on the upper 2 floors had in particular deteriorated over the years. We researched extensively replacement window options with a goal of respecting the architecture of the house, achieving energy savings and gaining functionality. In the end, these fiberglass windows best met al of our requirements. We replaced all the windows on the second and third floors, a combination of double hung and casement windows. All included grids that replicated those on the wood windows they were replacing. We are 4+ years with these 30+ new windows and could not be more satisfied. They substantially reduce noise, eliminated the prominent drafts we had previously, perform perfectly (up-down and in-out) and look great. Only if you are very close can you tell they are not wood.

Jammed the very first time I operated it. The very first time I operated this window, the sash jammed very solidly against each other. The window is stuck open and I cannot get it closed. May 10, 2013
