Trinsic™ Series Patio Door is rated 4.4 out of 5 by 36.
Rated 5 out of 5 by from ATTRACTIVE DESIGN & INSULATED TEMP MANAGMENT We purchased our Milgard Trinsic windows Feb. 8, 2019 from Andy's Glass & Window Co. The windows have been manufactured at the Milgard Factory in California and began installation on March 12, 2019. We immediately felt a reduction of solar heating as a result of the E Coating and inert gas captured between the panes. Our windows are so well designed and functional. We are Happy.

Rated 3 out of 5 by from took 2 months from the date of order for install The contemporary style window looks great and insulates sound and waether. Very happy with the product but something is wrong with the supply chain when it takes 2 months from date of the order from my installer.

Rated 5 out of 5 by from Impressed with these windows! Installed last week and absolutely love them. I was skeptical about how much sound they would keep out, as the rep said, and am so impressed with that characteristic. They look great too.

Rated 5 out of 5 by from Great for a rental property I bought this to install in my rental property from the old single pane windows and I know they will be more energy efficient and more quiet. Love the design.

Rated 5 out of 5 by from So far, so good! We have had these for about a week and so far they are terrific. We have an older home and the Trinsic Series windows look great with the look of the house. I love the smooth open and close operation of these windows.

Rated 3 out of 5 by from MISSED QUALITY CONTROL 2 - 18" x 42" UPPER PLASTIC LOCK CATCH TO LOW HAD TO USE GREAT FORCE TO OPEN AND THEN TRIMED THE PLASTIC CATCH IN ORDER TO CLOSE IT AFTER OPENING, OTHER 8 WERE OF GOOD QUALITY AND FUNCTIONED AS EXPECTED

Rated 1 out of 5 by from Poor quality windows The windows began to fail in our home at 10 years. The putty between the window panes is melting, running down between the panes and looks terrible. Per Milgard, since I am not the original owner, and it is outside of the limited warranty, I have to pay for all repairs on these windows. Be careful purchasing these windows!!

Rated 5 out of 5 by from Great looking windows The window quality is what I'd expected. Purchasing through Lowe's sucked. I ordered on October 8th, but it took until 1-31 to get installed due to Lowe's screw-ups.

Rated 2 out of 5 by from Smooth Operation But... Six of our 15 new construction windows have had issues. We are on our third service call. Issues range from gaps in vinyl framing, short cuts on mull and glazing blobs between panes.

Rated 5 out of 5 by from Great windows and doors I've replaced all my doors with Milgard doors and I'm in the process of replacing all my windows with Milgard windows. The doors and slider are more solid than anything else I've shopped and I'm very happy with the product. I'm staying with Milgard for every house I buy.

Rated 5 out of 5 by from Beautiful Windows went in yesterday, my views were already great and now the just look better! I almost don't want to put back up our blinds. They open and close so nice and love the locks. We can already tell the difference with noise and the heater doesn't turn in as much!! Love them

Rated 5 out of 5 by from Great sliding glass door This door is so great. We live in a very cold climate, in the mountain of Colorado, and you can't even feel the cold when standing next to this door, even in 20 below zero weather!! Looks great, slides easy.

Rated 4 out of 5 by from Great Window I bought Milgard because I know others that have it and I liked the look of the window. I was at a home show and they showed us how the window did not allow the heat from the lamp affect the temperature on the other side of the window. One room in my house faces the West and in the summer it was an oven from the direct sun and in the winter it is a freezer. This is why we bought a new window for that room. The room now has better temperature control but I wished they would have made the window closer to the size of the opening or old one. There is a 2 inch or so gap that was filled in because of the new window. Was this because there was an arch at the top of the window or is this how they normally do it? I don't know.

Rated 5 out of 5 by from Look good! Function smoothly! My Milgard Trinsic Series windows were just installed. It took me many years to replace my old windows. I wish I'd done this sooner. The new windows look so good and function so well! I particularly love the Pureview Mes screens. They almost disappear!

Rated 5 out of 5 by from Just replaced old window glass I called Milgard about our in window glass that went foggy between the glass panels. I was worried they couldn't replace it because so much time had lapsed. But the service department found our exact window and ordered the replacement form the original specs. Marco came today to replace the glass. It took 15 minutes and he was very knowledgeable and helpful. The new window is clear and was a perfect fit. Milgard is wise to make a product that last for a long time (10 years) and is easy to replace faulty parts.

Rated 1 out of 5 by from Milgard Trinsic Poor service 18 or 21 items received on 10/26/18 2 Weeks later stilling waiting for 3 back ordered windows. Milgard cannot even provide a delivery date. Screens were shipped with windows and show signs of poor handling at the factory 1 Awning will not close and lock One casement will need Milgard service to align properly.

Rated 5 out of 5 by from Guaranteed for life replacement We have had Milgard double pane final windows for 17 years and have been very pleased not only with the windows itself but with the guarantee for life policy. One of our windows developed a leak causing rust formation on the inner window. Milgard came out and replace it on time and very efficiently free of charge. Thank you Milgard!
