13 years with single pane windows and no dissatisfaction with the experience.
Of course we have no experience with double panes. So no means to compare. Just blissfully ignorant.
Putting a mask on the windshield exterior seems to be the best way to reduce interior heat from the sun.
All of our non-cockpit single pane windows are heavily tinted and the tint acts as a exterior visual reflector.

puff puff pass? LOL
glass has 200 times the thermal resistance as aluminum does. Cold temps are felt inside the rv on the frames nearly at the same temp as the outside temp. Aluminum conducts temp very readily.
Any ME's on board? You guys are always in the thick of thermodynamics.

I think the message comes down to what size screen mesh stops the most breeze. Glass is a poor insulator, aluminum worse. Double pane glass is slightly less bad but the inner pane often does not frost as much because the temperature differential gets the inner pane above the dew point. Given the amount of Aluminum vs Glass most of that cold cloud around the window is the result of heat exiting through the glass.
Anyone who is stuck in cold weather can do a lot of good with some structural foam and a duck tape over any exposed glass they do not need to see out of.

There is no space between the panes. The stone did not break the inside pane.

As far as I know every vehical windshield is dual pane laminated safety glass, (witch has "no space between the panes".
See: Laminated glass - Wikipedia, the free encyclopedia

I would say that dual pane windows, because they are thicker do cut down on the outside noise a bit more.....
Once I have cooled the coach to desired temp, I can keep the thermostat a couple of degrees higher than the last coach with single pane.

It's not the fact that they're thicker, it's the pocket of air between the panes. JMHO!

Shouldn't be any "air" between the panes, if there is the seals have failed.

Look at this cross-sectionial view. Sure looks like air space to me.

Wouldn't 2 pieces of something be thicker than one?...........whether it has a vacuum , air, or laminate, it would make "thicker".
I would also add with the single pane, we had a lot of moisture....with dual, we haven't had any except around the windshield frame.

Two pieces would certainly be thicker (and better) than one, but if you add an air space between those same two pieces then you've got even more insulation!

The Double Pane Sealed RV windows have a vacuum pulled on the dead air space between the two panes prior to them being completely sealed up.
That's why DP windows FOG up once that seal has been broken and it then requires the window to be rebuilt and resealed.
Double Pane Windows are the ONLY type of windows I will ever have. They provide better insulation and sound control.
I just wished that they would develop a self-cleaning DP window.
