Replacing dual pane with single pane?

Has anyone replace fogged dual pane windows with thicker single pane windows? I have a dual pane that is fogging and just wonder if it's worth the price of replacing it with another dual pane or just put in a single pane? I wonder how much difference their really is between the two in a motorhome?

    Well Sir,

    I'll have to disagree with you. And to the OP, YES, YOU CAN REPLACE IT WITH A SINGLE PANE WINDOW/GLASS. I know 'cause we did it. Our '99 Fleetwood Bounder, 34V on the F-53 Chassis and V-10, developed fogging in all four, forward windows. Both the sliders and the stationaries on the passenger and drivers sides. So, I went to a friends glass shop and we discussed changing them out to Single Pane windows. He said: "No problem".

    What we did was install "Laminated" glass in place of the Dual pane window glass. The Laminated that we used was equally as thick and, even had the same exact, "built-in" window tint as the rest of the coaches windows. All he had to do was install the correct window channel/butyl rubber that held it in place to the original window frame.

    Now, here's the kicker. I was told I'd get some serious wetness and sweating on the inside on that new glass. There was never, ever any sweating or, extra loud noise or, extra heat or cold due to the lack of the insulation factor of the original windows. Nope, never happened! Those new, Laminated glass windows worked flawlessly.

    But, here's some advice. The cost was very, very close to the same as it was going to be to purchase new dual pane windows. But, the true benefit was, NEVER TO HAVE THEM FOG AGAIN! Would I do it again, yep, in a heartbeat. Your choice.

    I base my statement on EXPERIANCE with both single and dual pane windows as a TECH that sees all kinds. Single pane windows have a tendency to rattle more than dual pane. I have had LOTS or arguments with various OEM's that install driver and pass side single panes and the customers that complain of rattle. Installing a single pane in the same width as a dual pane will cause MORE rattle/noise unless that single pane makes up the thickness of the dual pane. Dual panes are heavier and fit tighter and hence they do not have as many rattles as single pane windows. Doug
  • The benefits of dual paned windows simply outweigh the occasional problems. Quicker heating/cooling of the interior, less condensation when there's a large differential in inside/outside temp, less noise inside, are all benefits to dual paned windows.

    The OP could check on-line for companies that repair the windows, for a price, there are several companies around the country that do that now at a considerable savings over new windows.

    And if the OP has an older RV, and is a DIY'er, he could follow my instructions on repairing your own. It's fairly easy and only takes an hour or two.

    Agree with the above. Tiffin uses single pane glass, but it is much thicker than your typical single pane glass. No chance for fogging.


    Yeah, like your very thick laminated windshield never fogs up. :R

  • We have dual pane and will never have single pane. All I have to do is compare the amount of condensation on the single pane cab area windows to the dual pane in cold weather and the amount of cold that comes thru the windshield to the dual pane. That convinces me.

  • Go by your local glass shop and check the price to have your window repaired. Dual pane windows are used on a lot of residential properties and most glass shops can replace or repair your windows. You may find that the cost is not that high.
    Having had both, I will never have a coach without dual pane windows, for either Summer or Winter travel.
