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
