Randy, I put in some Milgard (SP?) double pane with low e glass two years ago, they are sliders and really seal well. I got the energy rebate ones, (you know, one of those subsidies that I don't get (DoH!) You can get them with or without the "dividers" in between the glass, but since they are fake why not just get a nice open view. These things slide and lock like a bank vault door.
