i am responding to the Atrimu review at city search. I am a 2 time customer of Tri State window factory first time i purchased from tri state was in the early 90's and it was ther weld tech 2000 window.This window was ther first generation vinyl window which was a standard window.Today Tri state manufactures a 5th generation window.Which means this window has been upgraded 5 times weld tech-2000 had 1/16 glass,metal spacer in between the glass which causes condensation because metal is highly conductive.This window also does not have low-e glass,and argon gas the window was sealed with one glazing sealed .The windows i purchased for my home in march 2010 was ther super high performance line Triple glass model 4200 series with a non metallic spacer in between the glass.This window is sealed with 2 glazing seals and filled with argon gas and foam filled frames.This window comes with a lifetime guarantee on labor and materials.I am a very satisfied customer i love my product.The windows that you have are ancient and need to be replaced.Also this new window has 1/8 glass double the thickness than the old ancient windows.cost more than the 20 year old window technology from 1990 that you referring and comes with life time warranty not the 10 year that you have which means you comparing apples with oranges
