Trinsic™ Series Patio Door is rated 4.2 out of 5 by 118.
Rated 5 out of 5 by from So clear This was purchased and installed by a volunteer group, working on my home. Cannot believe how clear the view is from a new modern design window, over the old aluminum that was replaced. Latch and lock work so smooth, and unit slides open and closed very easily. Just what I need being disabled.

Rated 2 out of 5 by from Doesn't slide well I bought 2 standard Z-Bar and 2 new construction single hung windows for our bathrooms. The sliding windows fit loosely, causing the windows to not slide well. Something in the rail even fell out. Not sure what's wrong. They do look beautiful though.

Rated 3 out of 5 by from Frustrated (2nd purchase) I just went to dry fit the window in the rough opening, and there is a crack in the window frame in the lower left corner. Now I have to install it so we can sleep in our bedroom until Monday, and probably wait another week or more to get warranty service. Very frustrating.

Rated 2 out of 5 by from Poor Quality Control on Painted Windows After returning the windows three times for quality control issues with the paint, welds and finish I reluctantly ordered a the second story of windows for the home we are remodeling. I am hoping that they can manage their finishes better and get some quality control in place or they are going to loose business and money doing rework on a product that costs more than the competitors.

Rated 5 out of 5 by from Excellent dealer! Was looking to replace older windows and patio doors in our house. Clayton Glass was the choice in Flagstaff! Installers were on-time and efficient.

Rated 2 out of 5 by from Nice clear glass but... I bought 13 windows, various configurations, and 3 sliding glass doors. The glass is beautiful and very clear and we love the color of the vinyl. However, if you are buying Trinsic with a 'jump frame' install, be prepared to lose a LOT of total glass area!! Trinsic is supposed to maximize glass area, however they do not work with the retailer and installer to ensure you keep this glass area maximized so you will lose greatly. Also, according to the installer, Milgard does not wrap ANY windows, so damage is frequent. Multiple units have to be buffed out and at least 5 screens have to be replaced due to scratches. Also multiple batches of flat trim was warped (again not protected in any way) and a new batch from the factory has to be ordered -- meaning my windows likely won't b e complete for another three weeks. Lastly, they don't feel as cool as they should so I am now left wondering if multiple Argon seals have been compromised because none of the window and doors are protected in any way. This has been an extraordinary pain and I'm sorry now that I replaced my originals because of all of the above hassels.

Rated 5 out of 5 by from Beautiful Sliders Ordered windows after closing on house. Moved in May 11. Windows were installed July. I am very pleased with how windows keep the heat from coming inside as well as the harsh sun rays. Outside noise is greatly muted.

Rated 5 out of 5 by from Great Value, Design and Installation! We just had US Window and Door of Carlsbad, CA replace 25 windows and 2 sliders with the new Milgard Trinisic series and we couldn't be happier! We first did extensive online research and learned that Milgard is by far the best quality and value. We then began searching for a Milgard dealer near us and found US Window and Door in Carlsbad, CA (just 10 min. from our home)! We learned that they've been in business since 1987 and are the #1 Milgard dealer in San Diego County, so our choice was easy. We visited their showroom and met Martin, the owner, who educated us on the unique features and benefits that make Milgard the best. He then came to our home, saw what we needed, and provided a quote that was surprisingly fair and affordable. Within 5 weeks, all the windows and sliders were manufactured and delivered. Then the US Door installation team arrived and installed it all in just 4 days! They have their own employees do the installation, not subcontractors. Their expertise, courtesy and work ethic was incomparable. And the windows are amazing … our home is much quieter, the windows and doors slide so easy and the exterior of our home now looks brand new. And when the installation was complete, our home was cleaner than before. Best of all, they are a local company (not way over in Arizona), so we know they stand behind their work. And the Milgard lifetime guarantee is unbeatable! If you are considering new windows, we strongly recommend Milgard and US Door and Window ... and we will be happy to chat with you personally if you want to hear more. Just ask Martin to put you in touch!

Rated 3 out of 5 by from Nice but The performance of the product seems fine but the construction of the corner joints are a bit sloppy. There were not enough screw caps included. I would recommend the product for a rental vs a home. Would probably upgrade for a home. Price works.

Rated 1 out of 5 by from Shattered after 6 weeks Six weeks after being installed the Milgard sliding glass door shattered when I was out of the house. I looked on the internet and saw where spontaneous glass breakage can happen with double pane tempered glass. The house project is not even completed yet. My previous sliding door lasted over 28 years. The door has direct southern exposure and it was 88 degrees that day. The contractor has left a message for them and I have notified Milgard online of this. It's a headache.

Rated 4 out of 5 by from So far so good. Only two days into having them installed but so far so good. The house is a bit quieter and seems to be a few degrees cooler on a typical hot day. The action on the double hung windows is a bit stiff but I'm hoping they will loosen up a bit with use. They look is great.

Rated 5 out of 5 by from Great value! My Trinsic series were installed a month ago. They are a great product at a very affordable price point. I did my research and had several companies come and give me quotes from different manufacturers. By far, I got the most reasonable quote for Milgard Trinsic. Also, they have one of the best warranties in the market!! The windows look beautiful, have all the bells and whistles that I needed. I highly recommend the product.

Rated 3 out of 5 by from Expected better I heard good things about Milgard windows so I bought one and installed it myself. Milgard refers installers to the AAMA 2400-10, which is an industry standard that explicitly says it is not intended to supersede the manufacturer's installation instructions. I think Milgard's lack of manufacturer instructions is a bit of a cop out, leaving the installer to do careful research into a wide variety of issues (e.g., compatibility of materials, etc.). The window itself (Trinsic) had some smudges and glue still stuck to it when I picked it up from the factory, as well as some other imperfections that suggest a lack of quality control. I expected a better product for the money.

Rated 3 out of 5 by from Acceptable window but not what I expected I just completed the install of 3 windows and a sliding door. One of the windows arrived with an exterior paint scratch and the door handle has a paint chip. One of the windows was out of square by 3/16 of an inch so a major pain fitting into a perfectly square opening. The patio door install tolerance was so tight we could barely wrestle this monster in. The patio sliding door arrived without the decorative plug to hide the adjustment screws. Having said that, the opening mullions are much beefier than expected so the viewing area seems restricted, I paid for the slimline Trinsic series so expected better. The latch system is acceptable and slides easily and once I get over the frustration of the install I expect the windows will function well.
