Many of the modern window systems will perform well, and no matter how much you pay for a window package there is usually an issue with some parts of it. Our advice would be to check some references for each company so that you can get an idea of who has better customer support and service, because anything can be fixed if there is someone who will stand behind their products and take care of their customers. You can also look at the warranty for the specific systems you are considering to see if anyone is much better or worse than the other candidates.

We went with Western and are happy with them so far. They’ve been installed for about two weeks in our active job site. I can’t tell any quality difference between them and Fleetwood so far, although I wish they were shipped with more protection as they did get scratched at some point prior to installation (probably careless handling by the workers). The scratches look pretty easy to paint over and are in pretty hidden places so not too much of an issue.

Western Window Systems

From what I heard Western is Milgard, no?!

Sometimes they are found in the same homes, from the same dealers, but otherwise it looks like their ownership is different (Western v Milgard)..... both having very strong production (tract) builder programs. I've used Fleetwood and have a home ready to order the same. Will also consider Western for projects. Prices will vary widely depending on size, glass, thermal breaks, etc. Go to a factory showroom if you can. Local dealer/installer network is critical for me.

Not to my knowledge but I am not that update on the residential product market any longer.

Western makes a few of Milgards over sized sliders.
