Not sure what state you are in, but uou may want to look into the following brands: Okna , Soft Lite, Gorell, and Sunrise. Each have a good, better, best in order to meet a budget. A solid mid grade will start around the
$450 per opening area depending on the scope of the install as well as options.
Stay away from places like Window World, home depot, or lowes. You will get low end garbage.

Thanks

+1 to mmarse's advice.

anyone hear of Eco-shield 2000 series? opinions?

thanks.

Never heard of it.

Do you have a CPD (Certified Products Directory) number or Structural test report?

Both should be available from your vendor.

Thanks fire the reply.

This is what I was given when I asked the person about the info.

They are made by Kasson and Keller who if I remember correctly were very much a builders grade product so I may be wrong but I do not think they would be considered a high quality product but more of a lumberyard type window (average at best).

thanks!

Btw, finding dealers for the recommended Windows had been really hard! For each one, there is one installer whose name I'm given and that's it!

Makes tough to compare apples to apples
