what area of the country are you from? what do you think the best windows are? Force V, GORELL,OKNA? ect...

north east. any one of those companies are good. Schuco is a great window but i am concerned with them (force v) being a start up in this sort of economy. i have heard that schuco was backing them;whether there is truth to that is anyone;s guess. we will find out about their viability soon enough.
Gorell is a great window,particularly their "armor glass".
Okna is a great winodw with some great numbers,this company has really caught my eye and i will investigate their products more closely.
TI also have their exclusive brand called Park Avenue. also a good window. then you have elements by a company called soft lite. great numbers as well. you need to see each window and compare specs and decide which is best for you.can't go wrong with either one in my opinion.

Any more info on Okna Windows? I need about 50 replacement windows in a large home in central NJ? Anyone interested?

Okna is one of the best windows available both from a performance and engineering standpoint. you will pay a bit more for Okna or any of the other top of the line windows but it is well worth it in the long run. with windows,cheaper is always more expensive.
many home owners try to play the "lets make a deal" game and wind up sacrificing quality and craftsmanship.
