HIGHLIGHTED REVIEW

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. - Seattle, WA

Customization options

A Frame for all Seasons

Ultra™ Series windows and patio doors stay true through almost any environment. Because it's made from glass fibers, the frame expands and contracts at approximately the same rate as the insulated glass it holds. This puts less stress on the seals, reduces the chance for seal failure while allowing for a clear, fog-free view.

Ultra™ Series Frame Colors

Milgard Ultra™ Series fiberglass window frames come in a palette of rich, designer colors. From warm 'harmony' to bold 'black bean', get inspired with all the possibilities.

Customer Reviews for Ultra™ Series Horizontal Slider

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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....

Rated 5 out of 5 by from 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!!!

Rated 5 out of 5 by from thrilled with the product! I am a senior citizen in a 1949 stucco home requiring 14 new windows. Tim Davis @ Agoura Sash & Door recommended Milgard to replace my existing windows. Excellent service, excellent turn around from time of order to final installation, thrilled with their perfect fit in my existing casings, could not be happier with the product. I highly recommend Milgard. It was a wonderful experience from start to finish! I feel that I got top quality with Milgrad at affordable prices. I am equally pleased with the Ultra Clad & the Wood Clad!

Rated 5 out of 5 by from The windows give us such good air flow now!!! The windows AND doors we purchased are just great. They allow us to get so much more air into the house now and the heaviness of the doors is very reassuring. The casement windows are beautiful too. We had two types of tinting put on the windows and got the fabulous screens that make it look like there are no screens on the windows! So clear and pretty to look at.
