Aluminum Window Durability

Strength
These patio doors are designed with clean, narrow sight lines that only the strength and stability of aluminum can provide. Milgard Aluminum Series patio doors are built with high quality components that start with our rollers and go all the way to the frame itself.

Contemporary Frame 
Aluminum patio doors provide narrow frames and clean lines offering a very contemporary look in any home. When a modern architectural style is desired, these patio doors can achieve a variety of contemporary design requirements.

Energy Efficiency
Milgard Thermally Improved Aluminum patio doors are equipped with a thermal barrier that makes them more energy efficient. Polyurethane is placed between the frame to create a thermal break reducing the flow of heat and improving insulating ability. (Not available in all areas.)

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.
