Horizontal Sliders

Horizontal slider windows slides to the left or right for easy-to-open capabilities allowing in natural light and fresh air.


Horizontal Slider windows open with the sash sliding left or right. Some people find sliding windows easier and faster to open than crank-style windows. Since they open and close without protruding, horizontal sliders are an excellent choice for rooms facing walkways, porches or patios. Horizontal sliders are a favorite for contemporary style homes and are also popular for satisfying bedroom egress requirements. In a single slider, one sash slides to open. In a double slider, both sashes open. Double sliders are great for providing air circulation, particularly if there is only one window in the room.

Rated 5 out of 5 by smooth operation Clean look, smooth and quiet operation, excellent fit into existing frames. May 28, 2016
Rated 5 out of 5 by Nice installation Great to work with Openclose in Tucson. Proposal and purchasing process was easy. Delivery was as promised. Installation crew was outstanding. Friendly, efficient, caring, and cleaned up the site. Just a couple of good guys. May 27, 2016
Rated 5 out of 5 by Great Product I highly recommend these windows for all your remodel or new construction projects. Excellent value and quality. May 24, 2016
Rated 5 out of 5 by So Quiet They Look so much brighter, and they kept out the neighborhood noise. Also the furnace did not turn on all night long. We are very pleased. And the installers were, clean, neat, timely, friendly and most of all, very professional. Overall, an exceptional experience. May 24, 2016
Rated 5 out of 5 by Great product for the price! We shopped around for two years for a replacement slider for our master bedroom. This product is affordable and looks beautiful. It exceeded our expectations, we love all the features and the door slides and locks easily. The product was on sale at Lowes, we had it installed by Lowes and are 100% pleased. Pella is way overpriced .... this is well worth the money and it has a lifetime warranty! May 23, 2016

Rated 5 out of 5 by Impressive I live next on a busy road. I can barely hear the traffic. Extremely quite and energy efficient. I love these windows. May 21, 2016
Rated 5 out of 5 by Sleeping better at night. We live off a rather busy street and have could really hear the traffic noise in our bedroom. We looked for a while for solutions and came across the Quiet Line series. After getting an estimate and contemplating if we wanted to spend that kind of money and take that chance we decided to go for it. Our windows have been in for almost a week now and we are so glad we went for it. We can still hear the traffic a little bit (I am sure because of older insulation in the walls) but it is so much better than it was and we are not getting woke up anymore in the middle of the night or early in the morning. Great window for sure and worth the expense. May 14, 2016
Rated 5 out of 5 by This product came in the exact size I ordered I had Milgard windows installed at my house in California and was very pleased. This time I was installing it myself so exact fit was crucial, and I got it! Installation was a snap! I would order again without reservation! May 7, 2016

Rated 4 out of 5 by Beautiful window - but some issues We chose Milgard Ultra fiberglass since we didn't want the maintenance requirements of wood, but didn't like the "cheap" look & feel of vinyl. Just installed today. Overall, we're very happy with the choice of fiberglass since the appearance of the frames both inside and out (we have the z-bar retrofit version over stucco) is simply stunning (looks like high-end wood trim.) Plus, we were able to choose an exterior color that coordinates with our paint scheme while having the inside white. However, there are some things to be aware of. First, you should plan on budgeting for extensive wood trim on the interior, as these windows do not come with trim pieces to "finish" the inside. Granted, this is a fantastic, rich look but cheaper vinyl windows often come with pieces to finish out the opening - these do not. Second, these windows do not have the ability to lock in a vented position meaning you'd have to put a wood stick if you want to leave your window cracked open. And lastly, since fiberglass is a heavier material the windows do take some effort to operate - but this is also a function of the tight seals. Overall a fantastic, beautiful window - just be sure to plan accordingly. March 29, 2016
Rated 5 out of 5 by New Windows We replaced our bedroom windows with the Montecito Triple Glazed - Tan (but it's more of a Taupe color) but we love the quietness of the triple pane & love the new color and the quality is great too, very happy and as we remodel the rest of the house will be replacing all the windows with them. March 27, 2016
Rated 3 out of 5 by overall product would receive a b+ Upon unpacking our window, our professional contractor with some 25 years experience pointed out that the spring loaded locking mechanism was not aligned properly. With further investigation we could see that the strike plate was not aligned so that the locking bar could not insert appropriately. I called Rafael Lumbar and no one called back (actually they did, after 7 days). Our contractor took it upon himself to access the problem area, file down the striker, and all worked well. The reason I choose Milgard was to avoid this type of poor manufacturing quality. March 24, 2016
Rated 5 out of 5 by Quick & easy installation The window is simple to use and provides an insulated alternative to the single pane window it replaced. It matches the other aluminum framed windows we already have. It fits perfectly into the existing decor of our apartment and allows us to inspect the back yard when the local coyotes and wild pigs make noises and need to be shooed away. We love our new window. March 21, 2016
Rated 5 out of 5 by A great product at a very reasonable price. This is our third Milgard window. They look great, but, more importantly, they work great! Our electric bills have lowered since installing them. The difference in the temperature in our western exposure living room is huge, especially June-August. We're in the Phoenix area, so it's imperative that the window do its job in keeping the heat out. Milgard delivers! The window gets only slightly warm to the touch, whereas our old single pane would practically burn your hand. They slide easily and we especially like the locking system - very easy to use.

Rated 5 out of 5 by Outstanding Products; Outstanding Service! Twenty years ago we had Milgard windows installed in our home - twenty in all. They have withstood the test of time. A few developed vapor between the two panes of glass. I called Milgard. After 20 years, I was expecting a runaround. I sent Milgard an email describing the problem. I received a call the next day, but was unable to respond to it due to a business trip. The Salt Lake City office called consistently to arrange a service call. Needless to say, I was astounded. The extraordinarily courteous and polite service person arrived at my home as promised, and on time. He inspected the windows and measured the defective ones. He promised to return in two weeks and replace the windows. Another surprise; two weeks later an installation technician arrived on time, and replaced the defective windows. While doing the work he pointed out that his colleague had overlooked one of the windows; one could hardly see the vapor. He returned two weeks later to replace that window. There are few companies in America, that will enthusiastically service their products, under warrantee, after two decades of service. I will never use any window or door products in the future other than Milgard. Competitors products may be less expensive, but wait until there is a problem. You will quickly wish you had invested a few more dollars in Milgard's product. Milgard's products and service, are , in my very strong opinion, the standard by which all other window companies should be judged. Well done Milgard for coming through on your warrantee after two decades, without hesitation. When Milgard says "lifetime warrantee," they mean it! That's why I will be a "lifetime" supporter of Milgard. March 8, 2016
Rated 5 out of 5 by This product has great features. This products has great features. It has the best design and quality. Most people like this brand because of good reputation and the warranty. My daughter uses this brand windows at her home and she recommends me to use Milgard windows for my home. March 6, 2016
Rated 5 out of 5 by Amazing look and quality! Had been dealing with draft from our son's room from pre-existing window installed incorrectly. Didn't want to deal with the issue again and skimp on quality. Milgard Tuscany slider window looks absolutely fantastic! Love it! March 4, 2016
Rated 5 out of 5 by Very nice windows These windows are very attractive and easy to open and close. Movement is smooth and they are air tight. I would recommend them. February 20, 2016
Rated 5 out of 5 by Such an Improvement It's only been one day, but the windows look Great and I'm excited to see just how energy efficient they are. If there is one small thing to be aware of, that should only affect your decision if you're a Crazy cat person; the retrofit windows took away about 2"-3" of our inside window sill, where our cats like to sit. I think they'll figure it out and get use to it. February 17, 2016
Rated 5 out of 5 by Thank you I couldn't be happier, after installing all the windows and two sliders in my house with help from a friend. They were very easy to install and had fun doing it. I saved myself quite a bit of money . Thanks Milgard Windows ! February 16, 2016
Rated 4 out of 5 by Very, very good windows My Milgard windows, both sliders and casement, were replacement windows, and they are good looking and work well. I used "new construction" windows and they have greatly improved the appearance of my kitchen and baths. They operate smoothly and for the cost, you can't go wrong with these windows. February 12, 2016
Rated 5 out of 5 by Excellent product After years with single pane windows I installed double pane, low e ones. The difference in heat transmission and noise from the street was immediately obvious. I'm not fond of the reflectiveness, but that is part of the trade off. The frame color bronze is actually black. All told though, the windows are an excellent product, extremely well made and will likely save money in cooling costs over the next seven months. February 11, 2016
Rated 4 out of 5 by Great Value Replacing windows was something I waited on for some time, right at the edge of what I felt comfortable doing myself. After getting shocked at quotes for installation, I tackled this myself, replacing 6 old steel single pane sliders with Milgard style line sliders. In general the installation was easy, with the only knock on Milgard being that I wish they took the extra few minutes to clean off the glazing and consistenly put the windows on bumpers so I didn't have to worry about scratching the vinyl setting the windows down. In operation they work tremendously better than the replaced windows, no duh, but they look pretty good, which for cheap replacement windows gave a good bang for the buck. I was looking for the slimmest vinyl product, and the Style line seemed like a good fit. We'll see if they hold up and if the seals last on the dual panes. In the end this was a simple and satisfying DIY project, with a cost comparable to to replacing say 500 SF of carpet with laminate (for the 6 windows I did). The renters did appreciate the new windows a lot. I felt this was worth it and the Milgard product worked well for me. Buying it at Lowe's, with their customer service worked very well in addition.

Rated 5 out of 5 by This window has ease of operation Horizontal slider slides very easily, has great sealing. Great energy efficiency 100% Guaranteed for life is finally what sold me. February 9, 2016
