Like many other reviewers, I am a repeat customer! Go figure! The windows are way too expensive for me, but on a whim, because I was so curious about their effectiveness after the sales pitch, I tried them for the living room of my trailer home. I had originally called to for a siding estimate, but the verdict was siding wouldn't work because I didn't have enough overhang. I was told windows would give me as much, if not more, insulating value because of my large window area.
Well, I was very pleased with the end result. Quick and flawless installation. Quick response to a sliding problem I had in the beginning on one window. Very handsome windows, easy to open and clean. They really clean up beautifully (I live right next to a railroad track), more sparking than my older windows when they are cleaned.
I am convinced the materials used in these windows are superior to the usual vinyl insulated windows. And their effectiveness is easily proved with a heat gun (what a great invention that is!). I have 3 different versions of double-paned windows in my trailer at the moment, and the NewPro 4000 windows outstrip the others in heat retention - only a couple of degrees cooler than the adjacent walls compared to the other windows 5-6 degrees cooler than the adjacent walls.
So, long story short, I am returning to NewPro for yet a few more windows despite the price being 2-3 times what I would think an insulated window with installation should be. I figure I am paying for peace of mind as well as for a quality product. I know NewPro won't damage my rather fragile home when they install the windows, and I know the windows will last me a lifetime, that if I have any problem with the windows whatsoever, it will be promptly fixed at no additional cost. I still feel like a fool, but a happy fool!
