Job was quoted for entire condo, but pricing seemed rather high. The old double pane wood windows were a little drafty in the middle of winter, but was looking for some noise control from outside. He said that the noise should be reduced greatly with the vinyl and the super spacer design and argon and low e. I wanted to make sure before spending the money for the whole unit, so just had them do the kitchen first to see if any noise reduction. I can tell you after 7 weeks, I actually can hear more noise than before, which was a surprise to me. I will not be able to tell what effect the windows will have on cold drafts until winter when you sit by it. The picture window portion was smaller than the opening once they removed the old window, they did not realize the the old window went back under a moulding further, so they shimmed it, and filled it will foam and let it set till Monday, and came back and added some more trim. I really do not think this is the cause of the extra noise, but not sure. I am so glad I did not do the entire condo for almost 12,000 dollars and have more noise. I am not sure it all vinyl windows have this issue. I went local thinking that I would get a better window, not true.I should have gone with a wood window and a name brand if I had to do it over. I had to purchase all new blinds since the way these fit in the opening and all the trim they use. Wish I had known that before.Would not recommend these windows for condo use at all, or a house with close neighbors.
