Dual pane windows.....add weight? Reduced CCC?
How much weight do dual pane windows add to a 5er over single pane? Seems to me that if they add quite a bit of weight that reduces your CCC.

It is not the energy saving that make dual pane windows valuable, it is the noise abatement and the absence of condensation on the inside of the windows. Single pane windows condensate badly in cool weather and one is always moping up the water and it could cause mold.
