Dual Pane Frameless Windows

[roadkingfl]

How can you tell if the windows are dual pane on these frameless windows?

[PolarBear]

Just like the glass doors I work with at work (HVAC) REFG, use a lighter or flashlight if you see One reflection, single pane, if two reflections then two panes of glass,,try it at your local store that has cold boxes, freezers will have 3 reflections,

That is COOL! Pun intended...

i wonder if they come with the winter/weatherguard package? I havent seen any info as to whether they do or not..only the insulation R factors really.

Dual pane window are definitely a stand alone option on all product lines. That's also true with most manufacturer's now making that option available.

I have seen where the cost of the dual pane windows is $1473. Does anyone know how much weight these windows add?

[RamGunner]

How much weight, and do they really make that much of a difference?
