Customization options

A Frame for all Seasons

Ultra™ & WoodClad™ 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.

WoodClad™ Series

All Ultra™ Series windows are available in WoodClad™ Series. The WoodClad™ Series option offers the benefits of fiberglass with the warmth of wood veneer on the interior. Milgard WoodClad™ Series windows feature the look of furniture-grade Douglas Fir without a nail hole or staple on them.

Seal with a clear sealant or stain the veneer to match existing woodwork. Choose from a palette of rich, deep colors for the exterior frame to express your unique style.

Ultra™ & WoodClad™ Series Frame Colors

Milgard Ultra™ & WoodClad™ 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.

Add warmth with a Clear Vertical Grain Douglas Fir veneer option on WoodClad™ Series windows.

Customer Reviews for Ultra™ & WoodClad™ Series Single Hung Window

Rated 5 out of 5 by A great replacement window My old window was rotting out so I needed a replacement. As I live in a apartment style condo I needed a paintable window. The sales man was very helpful in getting me what would work best for the size and new codes for the replacement window. Even though there was limited selection due to the original size and modern codes and not wanting vinyl, the window is very nice. Now I have a window that does not leak. And when the painters come I won't have to worry about them damaging the window with the paint. December 15, 2015
Rated 5 out of 5 by Great new windows for rainy side of house. I had 30 year old windows replaced on the weather beaten side of the house. The windows are attractive, maintenance free and very functional. December 9, 2015
Rated 2 out of 5 by good for summer bad for winter moisture on inside of all windows! The tabs on the screens are cheaply made. November 26, 2015
Rated 2 out of 5 by Very Frustrated We purchased 2 doors. One of them still doesn't close correctly it is out of alignment. The screens do not seal. The rubber seal is too short and the frames seemed warped. November 11, 2015
Rated 5 out of 5 by Exactly what we wanted We have casement black fiberglass windows. They refresh the look of the front of the house and the windows, themselves are beautiful. They appear well-built and the install process for the retrofits was painless and quick. We are happy with our purchase. November 1, 2015
Rated 4 out of 5 by These doors will make our house a lot more comfortable. I am shocked at the quality of product that made it out the factory door. I felt Milgards' standards would be higher. October 5, 2015
Rated 5 out of 5 by Great quality, value, and warranty. My wife and I seriously considered fiberglass windows from both Pella and Milgard. Both offer products of beauty and quality. We had quotes from both providers and Pella was willing to under cut the Milgard quote by 10%. However, Pella would not provide a Lifetime warranty. As warranty is a critical factor in the purchase decision for us, we selected Milgard. September 26, 2015
Rated 3 out of 5 by I like the doors, but the needed handle extenders are not available. The WoodClad patio doors work well. The rubber gasket on the sliding screen door doesn't seal and allows insects into the house. I showed that problem to the service tech. No help there. The wood(?) veneer on the inside of the door is extremely thin and with very light sanding to remove the soil left after the installation, I went through this veneer in a few place before I realized what was happening due to the sawdust obscuring the problem. Milgard should have had a warning on the door not to sand the veneer as it is not much more than paper thin. Of course bare wood gets dirty in shipping and handling. It now looks bad. The biggest problem with these patio doors is that I cannot fit my blinds on the door as the door handles are too close to the door. Only the narrowest of blinds would fit behind these door handles. The blinds need to drop down behind the door handle but there is not nearly enough clearance. I researched the problem and discovered that one can purchase "handle extenders." I emailed Milgard many months ago, twice, about which handle extenders would work with this door and they never replied to my emails. Most of my new Milgard windows wouldn't close due to a manufacturing error and after not being able to open or close the windows all summer I finally was able to use the windows after two tech visits, but a few still just barely close with more force on the latch than is normal. I can live with that. Back to the patio door problem. I took the door handle off the patio door and I don't see a handle extender that matches that handle, so after a few years we still don't have blinds on our patio doors. And Milgard hasn't answered any of my emails about this problem. If you sell patio doors you have to have handle extenders available for those doors, like other patio door manufacturers have.

Rated 5 out of 5 by Great Windows I just had two new Milgard windows custom made for my newly remodeled kitchen. They were made to match the other Milgard windows I had installed 5 years ago. They are exactly what I wanted. The noise reduction and heat retention is great. Highly recommend these windows. September 5, 2015
Rated 3 out of 5 by Not thrilled We had to send it back before installation because of two defects, one being a bottom sill runner that was peeling. A couple of months have passed and I already notice that the tan color is starting to come off this same runner. We spent a lot of time sealing, installing and framing the window so I am not about to take it out. Glad I have some warranty for down the line if it looks to bad. August 7, 2015
Rated 4 out of 5 by Beautiful windows, but finishing single-hungs is problematic. Installed casement and single-hung windows. Everything is fine except instructions that are on the window labels say to finish with a water-based polyurethane, which is fine for the casements, but the the bottom rail of the fixed pane is only partially accessible. No instructions are provided as to how to disassemble (and re-assemble) the window to be able to do a complete job. With the movable pane open, the entire bottom rail of the non-movable pane is visible and will be, at best, half finished. At worst, and likely, it will have drips of the polyurethane, which will definitely show. Is there a trick to taking out the movable pane so complete access to the hidden rail is available? I think this would also allow removal of at least some of the hardware for a neater job. I would like to apply the finish as suggested but feel stymied. July 25, 2015
Rated 1 out of 5 by Worst customer service Had a brand new house built and the builder raved about the warranty on Milgard windows. I live in Southern California where it rains abhout 3 times a year. The first storm came and two windows leaked. They sent their "most experienced" technician out who tinkered around and they leaked again the next time it rained. Now the customer service rep: Robin is telling me that excessive water runs down the side of the house and that is out of the ordinary for their windows. It might have rained an eighth of an inch last night and they leaked again. There is no way excessive water could run against my window with that little rain. They are just cheap poorly constructed windows. It appears the company is taking no responsibility. June 11, 2015
Rated 5 out of 5 by Great look - nice operation Our Ultra Series in-swing French Doors look great and the way they operate is second to none! The locking mechanism it easy to use and gives you a feeling your real secure when all locked up. Further, when you want booth doors open, it's easy to unlatch the stationary door. Great, well thought out product that looks good. May 24, 2015
Rated 2 out of 5 by Overly Complicated Door Hardware Very happy with the design of the doors and the look of the hardware, but the door hardware and deadlock are awful and poorly function. Easily able to shut door, but unable to lock door and feel confident door is locked properly when leaving. Went to showroom to see if it was our installation or a pour design and had the same issues trying to lock door at showroom. May 18, 2015
Rated 1 out of 5 by WoodClad windows use fake wood SGK sold me Milgard windows to match the Marvin windows installed by the previous owner. The WoodClad is a joke. It is "wood" is actually contact paper over a vinyl window. The advertising says, "Milgard windows feature furniture-grade, clear, vertical-grain Douglas fir." There is no way the frames are furniture-grade. They also say, "have a beautiful vertical grain Douglas Fir interior that is ready to take your stain or seal coat." Other than paint, you really cannot change the color of coating, as you can with real wood. Clear coating makes the 'wood' look fake. May 14, 2015
Rated 3 out of 5 by Doors The reason that I would not recommend this company is the customer service. Have to wait months for an appointment. Then have to wait months for a part and more waiting to get the part installed. The handles chip. The hardware for side lights on a French door are impossible to open. The screens were made to big and wouldn't slide. Could not get resolved so had screens made through a screen company. May 14, 2015
Rated 5 out of 5 by Screen latch replacement I am not sure of the specific product name because we installed the doors and windows 25 years ago. My concern is with the follow up service on the door rollers and screen door latches. The door rollers needed to be be replaced. I could not get an appointment for more than three weeks after I called. I also could not get the latches repaired even though I made 4 phone calls and sent photos of the broken latches. I was sent latches on two different occasions but they were the wrong size. I finally had to get replacements from Orchard Supply Hardware. The service person did not have the necessary parts to repair both doors even though I advised the order taker that both doors needed to be serviced. April 21, 2015
Rated 4 out of 5 by It's a very will constructed product and Milgard stands behind it's warranty great. The only reason I never gave this product a perfect review is after about 10 yrs (2) of my windows and (1) sliding door lost their seal and had moisture between the glass panels. Milgard was great about sendinding their repair crew out immediately and replaced the panels. I'm a retired General Contractor and these windows were in my own home. February 19, 2015
Rated 5 out of 5 by The Ultra Series is a good series purchase We installed 3 Ultra Series Sliding Glass Doors and 1 French Double Door and 4 Ultra Series Windows as well at this point. We did this thru a program with Home Depot which has allowed us to install these great windows and doors from Milgard. We installed the doors this past Fall of 14 and the the new windows in Dec. 14. At this point we truly pleased!!! I have had small issues that needed addressed with the doors and Milgard Customer Service was great!!! We still need to install several more windows and we plan on doing this still with Home Depot and the Milgard Ultra Series line. February 18, 2015
Rated 3 out of 5 by Solid product and great name brand Although I am pleased with the product, I am disappointed at the fact they do not service any issues regarding replacement of glass or screen frames to match the windows. If they are not a service company they should be able to refer experienced companies who do to back up their product. February 18, 2015

Rated 4 out of 5 by value for money These are great value for money and I don't know why you need more words then these. December 5, 2014
Rated 1 out of 5 by This product is not suitable for Southwest Arizona Chronic leaks, poor quality. avoid these if you can. December 5, 2014
Rated 1 out of 5 by Not Weather Tight I ordered two french doors with fixed side lights. Despite the side lights being fixed, they leaked and I could hear and feel the wind coming through both the side lights and the door frame. December 4, 2014
Rated 4 out of 5 by A decent window for the price. The screen is a little difficult to get out and the paint on exterior frame gets faded. November 29, 2014
Rated 2 out of 5 by The lock and closure mechanism is defective. I have had this door a month and it is still is not fixed. It was very expensive. It was defective when it arrived and I cant really open and close it without a lot of difficulty. After a month someone finally came to repair it but it is still defective. November 25, 2014
Rated 1 out of 5 by Don't waste your money We ordered the Ultra series out-swing french doors with sidelights and screen. The sidelights feature is very poorly designed because the screens are on the inside instead of the outside as one would expect. It is awkward to have to push the screen to open it, then unlatch the sidelight door, which is placed way to close to the inside of the frame, making it extremely difficult to open. Then you would shut the screen again to keep the bugs out. Despite asking several vendors about the outswing french doors, not one person mentioned this flaw in design for the sidelights. In fact, they sold us on the feature that the sidelights would open in (therefore, the screens would be on the outside, which is reasonable). I hope Milgard will change this bad feature of the door so that the sidelights open in--and make it easier to unlatch the door by not placing the handle so close to the frame. I was told that because we ordered the Ultra Series, the sidelights only open in the direction the french doors open. Also, paint on the hinges easily chipped off exposing an unprimed hinge underneath. I was highly disappointed in this product and wish we had been given proper information from the vendors.

Rated 5 out of 5 by Years of use and not a single problem! This is the second house I've used Milgard windows in. In the year 2002, I put Milgard windows in my 7th house, located in Durango, CO. That house is now a rental of mine. Not a single problem with any of them in all that time. There are some sliders, some casements and one awning. They all open, close and lock like new to this day. Interior screens, low-e double paned glass were what drew me to them originally. Some were replacements for insecure, old aluminum windows that were terribly inefficient, had a lot of solar gain in the summer, and many had failing seals. Others were casement and awning styles for the additional rooms created with a remodel, and replacements for the upper floor rooms. What a huge difference they made in sound transmission (so little afterwards) and no more air leakage. The energy bills really dropped for both winter and summer. When it came time to redo my current personal home in 2011 (which is house #6 for me), I had 4 casement Ultra windows, with low-e triple panes, put into a new addition (my new office) on the 2nd floor, over the living room. Two windows face directly east, one south and one north. They are perfect! I've never had any issues with them at all either. Love that the screens are inside mounted as it makes cleaning the windows so easy. There is virtually no outside noise from the backyard and neighbors anymore, when they are closed, and no solar gain either. The room is very quiet and very comfortable temperature-wise too. With the summer sun shining on them, if you put your hand on the glass, there is very little heat passing through. Keeps the office cool in the summer and warm in the winter. I also had an awning Ultra window installed on the west side of the house in another new addition I call the nook. It's actually an extension across the hall from my new office space, and is above the front foyer of the house. Currently, the room is used as another office space for my child and has bookshelves too. I also use the nook myself for non-work reading (cookbooks, travel books, art books) and file storage. The awning window faces due west. It's also triple paned low-e, and an inside mounted screen. When I sit at the nook desk, I hear almost no street noise at all, and there's very little solar gain. This nook also stays warm in the winter and cool in the summer, so no air leaking at all. So, after witnessing the wonderful virtues of the new windows, I decided to change out ALL my other windows on the first floor of the house to the Ultra series. In the basement I went with a different series from Milgard that are side sliders. What a difference they have all made in the noise coming in, the security of my house, and best of all, the energy efficiency. No more drafty rooms! I haven't had any issues with any of them. I still have more to install on the 2nd floor in the bedrooms, but these aren't going in until 2015, due to circumstances that prevented me from changing all of them earlier. I've had family members, some friends and many neighbors came over to see my whole house remodeling since I started it in 2011. They always notice how comfortable it is inside, and how quiet my house is too. I tell them it's the windows! It's why I chose these. Two sets of friends, one family member, and 3 neighbors have now switched out their old drafty windows to Milgard Ultras too. They have all said they too were very happy with the results. In general, fiberglass window frames have fewer problems than any other style of window I've ever lived with. They are far less likely to react to exterior and/or interior environmental changes. And, by the way, I've lived in no less than 16 different homes and apartments in my lifetime. I think some other people here maybe have issues for various reason. Often it's the fault of the installer, and not the windows themselves. They might have soil movement and/or house shifting issues, or more humidity where they live, which can make a big difference in performance too. When I start building my next house in 3 years, a straw bale one, I'm going to use Milgard Fiberglass windows again, and likely their doors too. October 28, 2014
