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.

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
Great Product We researched for windows for over 5 months. We found the warranty to be great and the product was what we were looking for. We replaced 14 windows. Most of the windows were surrounded with stucco and brick. Care was taken to not damage either. We are very happy with how they look inside and out. The day they were installed there was a lot of wind and I couldn't feel any air leak. We are very pleased. April 3, 2013
Do not buy these I purchased 9 of these double hung tilt and wash window..Withen the first year I had the repair man out at least 4 times and could have had him out more, but scheduleing that was a pain in the neck. When he did show after a three week wait, he was terrible to deal with. The internal mechanisms of these windows are plastic. I did'nt know this before purchasing. I wanted a low maintenance window for tropical conditions, and better then vinyl. So fiberglass seemed like the choice. The frames cracked within 2 years and all the internal hardware CONSTANTLY stripped out because it was plastic. Additionally they are very hard to slide up and down. I'm in my 40"s and I was thinking if I were elderly it might be close to impossible if I had to get out in an emergency (glass was tempered). I even tried to spray them with silicone and other lubricants. Do not spend your money on these windows. They are terrible. Buy the way I sold the house they were in and am now in another remodel and will not buy these windows again. March 20, 2013
