I did a few back windows in my house with the triple pane due to noise issue. It actually did nothing for the noise issue. The windows are great, as there are no drafts, but the tint from the Low E is very dark, I guess especially with three pain windows. We are going to do the rest of our windows but definitely not doing the triple pane, just double so I know it wont be too dark, but do places do windows without Low E? My house is dark as is and I don't like the tint that new windows have. Also, most of the windows I am going to redo get no sun. I really want to use the place we got the back windows, but not sure if I should look elsewhere.
