Energy Efficiency

Milgard SunCoat® Low-e glass is used in our Standard Aluminum windows for energy efficiency and comfort. It also helps protect against fabric and carpet fading inside your home.

Aluminum windows have an extremely long life and are highly resistant to outside weather elements. Because of their rigidity and durability, aluminum windows can be configured into combinations with a large glazing area for maximum views. They beautifully accentuate the clean, thin lines of contemporary design.

Aluminum Single Hung Window

Single Hung
With the Aluminum Series single hung window, the lower panel slides vertically upward when opened and it overlays into the stationary top panel. You can close and lock the window securely, in one motion, with the spring action lock. If the window is closed, it's locked.

Aluminum Horizontal Slider

Horizontal Slider
Horizontal sliders are one of the most common aluminum window styles seen in homes today. You can select which side opens, either left or right. The spring action lock lets you easily see if your window is closed and locked.

Aluminum Casement Windows

All Milgard aluminum windows are built to your exact specifications. Aluminum casement windows can be easily combined with other casements or operating styles for a dramatic effect. Casement windows open to the exterior of the home with a side hinge, similar to a door.

Aluminum Awning Windows

Aluminum Series awning windows are durable with clean lines and a modern look. This window opens outward from the bottom using a crank handle. This provides excellent ventilation in your home. 

Aluminum Picture Windows

Because of their clean, narrow sightlines, Aluminum Series picture windows make a beautiful wall of windows when used in combinations. These metal windows do not open, or have any rails to obstruct their view, making them ideal for large walls and high ceilings. 

Aluminum Radius Windows

The soft curves of radius windows make them very visually appealing. Try a full round, quarter round, half round or arch top. Combine a radius window with casements, pictures, awnings or single hungs for endless design possibilities.

Bay and Bow Aluminum Windows

Bay windows are commonly used for window seats and often have three separate panels. Generally shown with one large unit in the center flanked by a smaller unit on either side that opens for ventilation.

Rated 5 out of 5 by from Do it, you won’t be disappointed! I have lived in my condo for 27 years, and the windows were old when I moved in. Finally decided to get new ones, and I highly recommend the Milgard windows. They work beautifully, are well constructed, and I’m not afraid that they’re going to fall out if I try to take them out to clean them. What a difference clean windows and screens make. Very satisfied customer.

Rated 5 out of 5 by from Milgard had exactly what we wanted Of all the choices of replacement sliding door companies, Milgard was the only one that had exactly what we were looking for, aluminum bronze, to match our windows. The pricing was fair and the install excellent. A great team of installers did a superb job. Very happy with the results.

Rated 5 out of 5 by from Exactly what we were looking for 1960's Eichler style home with aluminum sliding doors, needed replaced along with 9 pieces of frameless full-hgt. glass units. Doors worked perfectly style-wise, ease and quietness of operation is a plus. Retained look of home, noticeable change in keeping cold out.

Rated 1 out of 5 by from *WARNING* WATER DAMAGE If you want dripping wet windows and water damage to your home- these windows are for you. For us this has been the worst product experience we've ever had. We moved into a brand new home in October and with the cold weather shift our windows were drenched in water (condensation) leaving puddles on the sills. I have to leave towels near all windows and wipe them dry every morning, but they drip all night long and I cannot keep up with it. I wish I could show the many photos and videos of this problem on here, but I will have to do that on other platforms. A rep from the company finally graced us with his presence to inspect the problem only to say it was a "normal and known problem for these windows but people still buy them." He was condescending, arrogant, and woefully uninterested in even looking at the windows and damages while in our home. He said it was an environmental issue - to which I pointed out that my neighbor's across the street had the exact same product and didn't have this problem, which means there is something VERY WRONG with our specific windows. He told us we would need to get them replaced, but that it wouldn't be covered by Milgard's warranty. He also referenced my concerns about the potential for mold and health issues if it wasn't taken care as the reason to have them replaced. This is because the widow is not separating from the sill, warping, leaving massive gaps for water to drip down into the wall. I'm not being dramatic when I say this is a serious problem! We will not stop sharing our experience, we will be posting this on as many websites as possible until Milgard makes this right on all fronts- windows, damages, and all. It's completely unacceptable and they should be ashamed for knowingly putting customers through this.
