I'm looking to get new windows for my house and some people have different spacing between windows like 7/8quot; to 1quot; and one says one is better than the otherBut which one is?

The distance between panes is a function of insulationInsulation works by trapping air and causing slower heat/cold transferA larger space is better you can also have the space filled with low E Argon gas or a reflective UV membraneChoose a reputable manufacturer and do some research online the time invested now will be cost effective later.
