Style Line® Series Radius Window is rated 4.4 out of 5 by 647.
Rated 5 out of 5 by from Beautiful Windows We purchased a 1970s home needing to have all the extremely large single-pane aluminum windows, along with the 6' and 8' Sliding Glass Doors replaced. These were the perfect option. Not only are they beautiful, and stylish, and secure - they fit our budget! Easy to install. Extremely happy with them.

Rated 5 out of 5 by from We have style line 'cottage' windows. Love them! We have Milgard throughout the house. We love how they match our 1937 house! Cottage style frames are perfect. They transformed how quiet & warm our home stays. They also allow a breeze when needed. Couldn't be happier!!

Rated 3 out of 5 by from 20% of windows were flawed We just completed the install of 32 Milgard windows in our home and while we are happy with the windows, we were not happy to find flaws in 7 of the windows....scratches in the middle section of the windows. Of course these are covered under the Milgard warranty, but after an install that took almost two weeks, the last thing we want is to have more installers in our home to replace seven windows. I would caution anyone buying these windows to examine each window very closely for flaws in the inner window section,

Rated 5 out of 5 by from Great quality at great price= Awesome value Combination of picture, single hung and slider windows. I am a Milgard loyalist both at work with my business and at home. The quality and service is always consistent. Milgard is my first choice everytime. Hundreds of installs every year.

Rated 5 out of 5 by from Excellent warranty I’m a General Contractors and I have been recommending Milgard Windows for over 30 years. I even installed them in my own house!

Rated 5 out of 5 by from Good Quality The windows appear to be very good quality, the screens fit good, and the windows slide easily. I was pleased to obtain a large window, 72" by 82", for my dining room. I look forward to see how the windows perform over time.

Rated 5 out of 5 by from Fantastic windows We ordered replacement Millard windows through Home Depot and used one of their installation companys. We could not be happier. The windows are top quality, they operate so smoothly and we can not believe how clear they are. Thank you so much for such an incredible product.

Rated 5 out of 5 by from PERFECTION! The quality of these windows are just phenomenal. The glass is exactly what I wanted. The sound they make & the feel when they close is fantastic. the house performs better with the outside temperatures. Couldn’t be happier!

Rated 5 out of 5 by from Nice Addition to Our Home Replaced 2 bedroom windows and 2 bathroom windows and we are extremely happy with these units. They slide and secure nicely and we noticed right away the noise reduction from what our old aluminum single pane windows allowed. We would recommend these windows to our friends and neighbors.

Rated 5 out of 5 by from Awesome windows! These windows replaced 70 year old aluminum framed windows. I am thrilled! They are cleanly styled, help with temperature maintenance and are easy to operate. Thank you!

Rated 4 out of 5 by from nice window & doors we had these installed in our new house,windows are great, doors were not so well fitted,hinges off and door strikes not in place with latches, not the american quality fit you would expect for us here.

Rated 5 out of 5 by from Awesome fit. I just stucco my house and while painting the trim I noticed one of my windows had moisture staining in between. So I “you tube” it and realize I could replace it myself. I went to Ganahl Lumber and order the window, and a month later I installed it. It fit like a glove, what a nice product. Very happy I purchased this product. Obviously it was a much superior product for what I replaced.

Rated 5 out of 5 by from Excellent Choice In this Texas heat the windows keep out a lot of the heat especially on these hot days. I am anxious to see in the winter when the cold wind blows.

Rated 4 out of 5 by from Great window The window we ordered is just what we expected. However, we were surprised to pick it up from the store without any protective wrapping on it. Luckily all of the marks on the glass and frame came off.

Rated 5 out of 5 by from Looks classy.! We just had them installed. Can already feel the difference in the diminished amount of outside heat that comes through.

Rated 5 out of 5 by from Excellent windows and price I'm upgrading my windows from single paned to these. It's night and day. I can't hear the cars drive by with the windows closed anymore. It's awesome.

Rated 4 out of 5 by from Nice windows Nice looking windows, easy replacement. Only thing is the screen is a little hard to pop in and out.

Rated 5 out of 5 by from Great windows We just had two windows replaced with Milgard. Very pleased with the windows and like the latches to open windows. They slide easily. The only thing I think would be nice if on the screens they had metal pulls instead of plastic. The plastic ones come out to easily and are hard to grasp and pull screen out.

Rated 2 out of 5 by from Good windows if they got it right! First off the windows are nice, but they came wrong size on one, one was broke, the rain glass on one is wrong and it is still in my bathroom. took 3 weeks to get the wrong sized one back. two weeks for the broke one fixed. some of the windows installed from the outside look like a two year old installed with holes in the caulking and the caulking looks like a two year old installed. not happy with what i am paying for.

Rated 5 out of 5 by from Really nice windows I've only had them a few months but I've already noticed how much they cut the street noise and insulate against cold and heat. The windows also work very smoothly.

Rated 5 out of 5 by from Very happy I received an estimate last year and I kept in touch with my rep until I was ready for my install this past April. I am very pleased and I am thrilled that I can sit in my front room during the hot summer months in Las Vegas.

Rated 5 out of 5 by from Awesome windows After having old aluminum single pane windows on my residence that didn’t lock anymore, I’m beyond thrilled with the 3 new windows. It is quieter, more energy efficient and they move so easily. As I am handicapped, this is important to me.

Rated 5 out of 5 by from Beautiful Windows! I had styleline series windows installed on my house and what a difference! They look great and are much more energy efficient than the previous windows. Also they were installed professionally by Jack who did an excellent job!

Rated 5 out of 5 by from Round two In 2018 I did my first floor backside of house windows (13) and the difference in sound / heat and cold transference was amazing. What I expected and appreciated. What impressed me the most is the installation crew was very diligent in making sure my interior remained clean and the install was of first quality. This most recent install was for the second floor backside of house windows (11). I requested the same crew (Rafael and crew) and was accommodated. Rafael and his crew are the best and I will be requesting them again if I replace my front of house windows with Milgard. My only issue at this time is the pricing I am receiving is very high when compared to what I was quoted before.

Rated 5 out of 5 by from 100% Satisfied They look and work great. Such an additional to the look of my old home.
