And the colors of the frames are nice too. We got an off white color called Canvas, very neutral and somewhat off the beaten track.
OF COURSE we got Low E for energy efficiency. Our heating bills should be really small... and you can shine a huge light and feel NOTHING on our side of the windows.
Our local Anderson Windows contractors in Las Vegas were ok, the sales person was really straight, but the contract writer made a few mistakes and inverted a few windows... but the windows themselves are so nice we were not at all concerned.
For comparison, I have a funny story: We saw some replacement windows at my husband's sister's place and they were terrible... they were cold and rickety to the touch. We are SO GLAD we sprung for the top of the line windows.
Sun City Windows is the local subcontractor where we live in sunny Las Vegas. No relation, just happy customers.
