I am replacing over 30 windows in a 1924 2000-sq.ft. two-story house in Berkeley, California. Because I want a window that will last forever, and will never fade or yellow or warp, without maintenance, I have decided on fiberglass.
While I appreciate your decision criteria, do you think that vinyl will not last as long? There is no data to indicate that premium vinyl will not last just as long as Fiberglass. I do like Fiberglass, however, the folks that market it as lasting forever where vinyl will fade, yellow, or warp are not speaking the truth if they are using that same argument against very nice vinyl. If so, why would Milgard offer that same lifetime warranty on their vinyl windows?
I have received bids on Marvin Integrity and Milgard Ultra. So far I see two significant differences between the windows:
-- Milgard offers a full lifetime warranty on everything, whereas Marvin offers only a limited 10-year defects/20-year glass warranty.
-- Milgard is a lot more expensive (as much as 50% more, I think).
Have you looked at the Marvin Infinity? Marvin Infinity also comes with a lifetime warranty and is more aimed at the retrofit market.
Given this, here are my questions:
1) Why is the Milgard window so much more expensive? Is it because Milgard offers a better warranty, or also because Milgard is better quality? I read that generally Marvin is a higher-end window than Milgard, and read good reviews of Marvin Integrity, so I was surprised that Milgard Ultra is more expensive. Can anyone explain this?
Not sure. Commenting on pricing is difficult because you never know what it cost a particular vendor to "do" business. I will say that the Integrity is often aimed at the new construction market and in doing so, probably makes sure that they are even in the running by keeping their price reasonable. You don't see to many Milgard Ultras in new construction. Again, if you are concerned about the warranty, look at the Infinity.
2) I have read that fiberglass windows will last much longer than vinyl, without fading, yellowing, or warping, and with essentially no maintenance. Does the experience with fiberglass to date support this?
Fiberglass has some advantages to it as a material but there is not much data to support the idea that well engineered, proper materials, and built vinyl will last any shorter than Fiberglass.
3) I read on this site about a fiberglass-window company called Inline, but haven't been able to locate a dealer in California. Does anyone know anything about the price and quality of Inline compared with Marvin and Milgard?
Impossible to comment on price but I can call Inline and see if they ship to CA.
Of course, I welcome any other comments on the price and quality of fiberblass windows.
What type of windows are you replacing? What type of construction?
