Trinsic Series modern single hung vinyl window

Single Hung
Trinsic Series single hung windows open and close easily in an up and down motion with the redesigned SmartTouch® window lock and handle that is unique to this series. The new hardware practically disappears from view when closed, keeping the contemporary feel of the series intact.

Trinsic Series modern horizontal slider vinyl window

Horizontal Slider
Horizontal slider windows open and close easily without protruding into exterior walkways. The SmartTouch® window lock, specially redesigned for Trinsic Series, offers a new modern look with a squared-off profile that blends into the frame. SmartTouch makes it easy to unlock and open your window with a single motion.

Trinsic Series modern double horizontal slider vinyl window

Double Horizontal Slider
A double horizontal slider (also known as a double vent) allows you to open your window from both sides with a fixed sash in the middle. This operating style also utilizes the SmartTouch® window lock with a squared-off modern profile that practically disappears from view.

Trinsic Series modern casement vinyl window

Casement windows are hinged on one side and open outward like a door. They can provide ample ventilation in any room. The crank handle folds and nests when not in use for a clean look. This operating style works well on upper floors, or those with no exterior spaces without walkways.

Trinsic Series modern awning vinyl window

Awning windows are the perfect solution for hard to reach areas of your home. The window is hinged on top to open outward. This enables ventilation while keeping the weather outside. They open and close with the turn of a handle. Consider pairing them below Trinsic Series picture windows.

Trinsic Series modern picture vinyl window

Trinsic Series picture windows let you maximize your view with no obstructions. They do not open, so consider pairing them with operable windows to enjoy both daylight and ventilation in your home.

Trinsic Series modern radius vinyl window

Radius windows have a rounded top, which can break up the hard edges of a room and even add whimsy. Consider this window style for full circles, half circles or arch shapes. Radius windows can be operable or inoperable, to suit your exact needs.

Rated 5 out of 5 by from Beautiful windows Just purchased and had our Trinsic windows installed and WOW, what a huge difference!! Our home looks much more up to date and modernized. The windows allow so much light in and we love the simple lines of the series. The windows have such a clean and sleek look, no more grid lines! I'm extremely happy with the windows and know I will enjoy them for a lifetime!

Rated 5 out of 5 by from Seals up home well and helps keep afternoon sun co Main thing I notice is rooms maintain their ambient temperature much better. No more drafts when wind is blowing. The freeway noise is almost silenced when everything is closed. The locking/unlocking mechanism is smooth and out of sight line.

Rated 5 out of 5 by from Energy Savings We bought a well built home, but the previous owner had installed Vinyl windows with two panes of glass and no energy features, thus a negative affect on utility bills. We are very happy with the Milgard Trinsic Series, and have immediately noticed the difference in the household heating. We especially value the security features of the windows. We installed single hung and sliders. The windows finish is excellent. We also value the lifetime warranty. We would recommend this product of anyone who asks. The promotion offered by Milgard through Home Depot was also beneficial to our finances.

Rated 5 out of 5 by from Beautiful looking windows! We had these windows installed and they look great. The temperature in our home is already more regulated and outside noise is not as apparent. The details in the windows are lovely, including the beveled grid pattern and locks that function seamlessly.

Rated 5 out of 5 by from Great Installation Crew! After placing our order with the sales representative, our next contact was with Shaun, who came out and took measurements, stayed in contact regarding the installation date and, with a helper, saw to the removal of the old windows and the installation of the new windows. Shaun has been friendly, positive, and professional all along; today he impressed us with the alacrity with which he executed his responsibilities. Things were done quickly and professionally, and when he was done, the new windows looked and functioned great, and he left no mess. Color me impressed! I almost forgot to mention the windows themselves, which are terrific.

Rated 4 out of 5 by from Beautiful windows. Not so great customer service. We purchased the trinsic windows for our home and are super pleased with the look and feel of them! They are gorgeous and the crank to open the window is flush with the window and very visually pleasing. That being said, our windows took twice as long to ship as was estimated and there was no good way of finding out where they where. Once they did arrive we where missing almost half the order and what we did receive, most of the screens where damaged in shipping. They are sending us replacements but that will take time as well. I also wish the windows where more clearly labeled as to what each window was. We had a very hard time figuring out where each window was to go in the home. Over all we are still happy with our purchase, just would have liked to have been treated better as a customer.

Rated 5 out of 5 by from Just right... They’ve only been installed for 3 weeks, and so far....I love them! I did find 2 “etchings” on one window....I called today, but they haven’t returned my call yet. It’s only been 3 hours.... I love how easy they slide, and the “newness” of them....

Rated 5 out of 5 by from Great quality windows. We bought our new windows about a month ago. We are really impressed with the quality of the windows. Easy to open and close, the windows lock automatically and slide very easily. We are so pleased!

Rated 3 out of 5 by from Beautiful appearance Where I like the window, I don't care for the factory sending out a window pane with a foreign object encased between the dual panes. This requires another to be delivered and that pane to be replaced with one that is correctly finished.

Rated 5 out of 5 by from Perfect Contemporary Window Was looking for a modern thin stile window to compliment the look of my 1950's home...and the Trinsic series looks great. I went the tan color and in-glass flat grid to match my original windows. Especially appreciate the nicely integrated slider handle. My local installer Dee Jay's Glass was awesome as's like the windows were always there!

Rated 5 out of 5 by from Great Windows Windows are great. Installers were professional. Do I still get my Amazon rebate?

Rated 5 out of 5 by from Great features We bought both Trinsic and the pricier Ultra windows (and a Trinsic door). We love both. We went with the Ultra for most of the house where the sun is vicious - they seemed more durable and (I think) have a better rating for solar heat gain. The Trinsic we installed downstairs are really nice - a thinner frame and frankly I like those closures/locks much better. They are very attractive, streamlined and flush with the frame, whereas the Ultra have closures which are more prominent. For us, that doesn't really matter as much as they are behind plantation shutters. The Trinsic door is a dream! Slides so easily.

Rated 5 out of 5 by from Wow, I can hardly beleive the difference! They finished installing the windows today and they shed a whole new light in the house. They are easy to use and the explanation provided by the installer was very thouough. The team cleaned up and removed all debris. I'm even looking forward to winter this year. What a difference! Thank you.

Rated 5 out of 5 by from I am able to open windows in my house. Fresh air! My previous windows were taped shut because they fell out of the casings. They make my home more open, appealing and update the kitchen area. I will order 3 more windows in November. This will make the house weatherproof for the winter.

Rated 5 out of 5 by from great Features The windows are have reduced the incoming heat but not the light. They open up very wide for awning windows and allow a a strong breeze. I am very impressed with the way they function they turned out much better than I expected.

Rated 5 out of 5 by from Savings!! A week ago my windows were replaced with R.O.I. windows. That was one of the best decisions I ever made. They not only look great but will save on electricity now that the leaks are gone. They are so easy to open I will enjoy the cooler fall days with the windows open! Thanks R.O.I. for a job well done.
