the windows I bought had 3 panes of glass with u.v protection.was replaced with 2 panes no u,v protection hot cold comes in bad. I have told them several times they did not replace with what I had they give me the runaround the 3 panes a big blue spot came in them that why they replaced with the 2 panes that I did not buy.
they did not have u.v or inferred protection I would not recommend window world to anyone. The windows I bought were the guarantee for life and were not replaced with the same quality I bought.
the inferred kept the hot and cold out or in. the windows I got now hot out side heats the inside cold is cold inside
