Thermally Improved Aluminum Windows

Milgard® thermally improved aluminum windows have a light commercial rating.

This means in addition to being excellent for use in homes, they can be used in schools, restaurants, government buildings and other light commercial applications. Their high-performance thermal-break frame design and higher thermal rating means greater energy efficiency. Milgard's sealed, mechanically joined corners stay square and true over years of use.

Our thermally improved aluminum windows feature Milgard's SunCoat® Low-E high-performance insulating glass (standard in all Milgard windows and doors). They also include the Positive Action™ lock on sliding and single hung windows. When your window is closed, it's locked. No more wondering if you left a window unlocked in your home or business. For salt-air climates, Milgard offers an optional stainless steel hardware system to minimize corrosion. Like all our windows, our thermally improved aluminum windows are custom made to your home's exact specifications at no extra charge or extended lead time. What's more, they include our industry-leading Full Lifetime Warranty.

The appearance and quality of Aluminum Thermal Break Windows exceeds windows of other materials I researched replacement windows of various manufacturers and materials prior to selecting Milgards Thermal Break Alumimun Frame Window. After seeing a Milgard sample window and cut through a frame member my lifetime of experience in the design and construction field convinced me this was an excellent product and my choice for my 30 year old home.

I specified Thermally improved but-- I have had several glass units replaced because of internal leaks and all of the frames get ice on the inside November 30, 2014
I'm impressed by the product. I was not interested in Milgard windows in the past. Had seen them installed in new constructions and they seemed a low quality product. I went in and viewed the aluminum series. I bought 28 windows and sliders. I was happy to see what the quality of the product received upon delivery. My building is looking so much better with these new windows and sliders. As we are in very close proximity to a freeway, the improved sound control in the units, is very much appreciated. I highly recommend Milgard's thermally improved aluminum windows. November 22, 2014
Looks great but beware if you ever plan to open your windows The positive: These windows are beautiful architecturally. I'm a professional architect and have used these in my own modern home. The negative: The screens must be removed or opened via hinge every single time you want to open your window. It is a huge hassle and the tiny plastic clips that hold your screen frame to the window frame break very easily (mine snapped off after just opening my windows three times. The window mechanism should be designed so that opening via crank, etc. can be done without having to first open the screen. October 28, 2014
Horrible Product! I moved into my house when it was barely 5 years old and the windows have been terrible since day one! They have broken seals and I am forced to put plastic coverings on all my windows in the winter because you can feel a breeze when sitting on the couch. The company refuses to fix the broken seals because I am not the original homeowner. These windows were obviously defective when put in or the material is such poor quality that all their products function in this manner. I will be sure to never purchase or recommend this compant to anyone. August 6, 2014
HARD TO OPEN AND CLOSE We have great milgard vynil windows in our current home. We decided to go with the aluminum for more of a modern look for a new house we are building. BIG takes me a long time to open these windows. Sometimes I can't even do it. I have to wait for my husband to help me.Be warned! April 1, 2014
Terrific windows We replaced all of our single-pane aluminum windows with Milgard's Thermally-Improved Aluminum windows with SunCoat Max glass. The windows are terrific! Our Phoenix, AZ, home is much more comfortable - so much that we no longer need sun screens. On some of the larger picture windows, we've even left the blinds off! The interior glass and frame get only slightly warm to the touch, and only when hit by direct sunlight (which is pretty intense during AZ summers). The windows were installed by TrueView Glass and Windows of Phoenix, AZ. They were terrific throughout the entire process! Now for the negative. We ordered new-construction windows for the entire house. Four of the windows sent by Milgard were incorrect - 1 was 8 inches too short, two were missing grids, and 1 had the incorrect obscured glass. Upon reviewing the paperwork with TrueView, we concluded that Milgard simply sent the wrong products - likely a data-entry error. All measurements and options on the order were correct. Fortunately, Milgard corrected the problems by sending replacements, however, it added about 6 weeks to the project. I am giving the product 5 stars because the windows are absolutely terrific - they look fantastic, they are incredibly sturdy, and they improve the comfort of our home - these were our objectives with this project. Despite the delay, the final result was worth the hassle. August 1, 2013
Durable, well made, fair price. I added Milgard windows to a living room addition and they performed well. I have a bay window with a horizontal slide in the middle and side picture windows. Two more horizontal sliding windows further back in the room complete this addition. After twenty years they havent broken, or fell apart, though they are becoming a bit difficult to open now.
