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.

Beautiful quality! Very happy with the look and feel of the Ultra French Doors. We were able to get a custom size and love the hardware we chose. The style blends nicely with the rest of the house. Handle lock is a little tricky, but we're already getting used to it. Glad we made the decision to go with Milgard once again! December 30, 2013
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
My French style sliders doors are perfect! I am thrilled with my selection of the French Style slider. I replaced traditional wood French doors that were old and damaged by water. The look of my new doors has a much more open view. I highly recommend the Milgard doors, next will be replacing my windows. July 26, 2013
Form follows function Wonderful quality door, but that's not why I bought it....I bought it because of Milgard's reputation for service after the sale.....Beautifully balanced swing on each door. quality materials-stainless steel hinges and door handle...about the handle-it's a 5point locking mechanism which I appreciate for it's superior locking/security- and you need it in a french door....the door was factory painted-and the finish is indeed superb.... I had a problem with that door lock -it closed with difficulty after 6 months, so I called Milgard and they had a tech out quickly...he was professional, efficient and fixedthe issue.... I wish Milgard made single doors-they don't....the door is very expensive, but you do indeed get what you pay for when it comes to doors.... December 18, 2012
Amazing Door. This door is more solid that he solid door that we replaced. I didn't think that possible. We absolutely love it!! it looks perfect like it always belonged there. The added screen feature we are for sure going to love this summer! Everything came pre-installed, all we did was put it in the hole in the house, and poof it was perfect! My only problem was figuring out how to operate the handles. That was a learning curve, as we had no directions included with our door. When we figured this out, it was a very impressive door, with amazingly secure feel. Would order from Milgard over and over! Thanks!!! February 27, 2012
The Milgard ULTRA product and professional installation exceeded my expectations! Window replacement began as a stressful process until a contractor/friend recommended Milgard. We discussed in detail all factors important to me. I was able to narrow down the manufacturer and product line to Milgard ULTRA; I then decided on new window construction (nail fin). Next step was to find a "professional" company to order and install the 9 windows. Cunningham Doors & Windows (Santa Ana, CA) provided the best customer service. Their installers did an extraordinary job on every window. I have neighbors stop to admire and inquire about these new windows -- wow! My family is very pleased with the Milgard ULTRA windows.

Superb service on Warranty I'm fairly jaded when it comes to warranty repairs of anything: in fact I forgot my 1996 installed widows and doors had the "lifetime warranty" until a friend advised me of the fact. Still somewhat wary, I called the service representative, and have received competent, cordial, and effective repair of both two sliding doors and two fixed windows. I do not impress readily, but I AM impresssed.. Excellent product! September 27, 2014
Great windows I am a contractor in Arizona. When I went looking for windows for my own home I did alot of research about windows for a hot climate. Milgard Ultra came out on top. I installed twelve casement windows 8 years ago and have been exceptionally pleased with them. The 3D glass system is amazing, our home is radically more comfortable in the summer. We live on a busy street and the traffic noise reduction is probably 90% over our old aluminum sliders. The white fiberglass frames show little to no signs of aging after 8 years in full desert sun. The operating mechanisms have had no issues and the windows still operate fine. I have had only two minor issues with these windows; the screens have sliding retaining pins in the four corners, but they are a pain to install because the pins don't line up well with the window and the pins get sticky and won't slide. I believe the newer window screens have a better retaining system. The only service issue I have had in eight years was with the outermost weather stripping. It is exposed to the elements, and the original product failed ( became sticky, decomposed and retained dirt). I contacted Milgard and they came out and replaced all of it, no problem. Lifetime Warranty!! I highly recomend these windows, my only regret is that soon after I purchased them Milgard came out with an even BETTER glass system, 3D Maxx South. They have a HUGE list of available options with these windows, I have sold these windows to my customers since 2006 and the feedback from them has been equally positive. The price is competative with other premium windows, value is unbeatable in my opinion. June 26, 2014
