When mine need work I’ll install single pane e-glass or laminated single pane. Have Jeff at ETLC or The Fog Doctor in Searcy, AR fix you up. Here’s a link. If it doesn’t work? put the word “Sikaflex” in the search engine here.

We had the fogged double pane replaced with single pane on all 4 cockpit sliding windows. Had it done at The Fog Doctor in Searcy, AR. Be aware that the rubber slider seal strips (inside and outside) are no longer available from PrevostPrevost. When you go from the double pane to a single pane, the window contact angle of the seal changes, and has a tendency to bind when you slide the window open or closed. The rubber has increased friction on the glass because of the increased angle of the seal with only the single pane. The increased friction tends to stress the seating channel for the seal until the rubber seal looses some of its memory, and may cause the seals to come out of their seat. We had the replacement done about a year and a half ago, and still occasionally find one of the seals working out of the seating channels, depending on how much I open the window. You do not want to loose those seal strips…which you could easily do if you’re inattentive.

Had Prevost do mine (drivers slide window) in Houston right after they opened shop a few years ago. $1200 bucks. Seen me coming.

Thank you for the replies. I read the link to the previous conversations on the same subject. I am reading that the Prevost replacement is not a fix. 18 months and back to foggy windows is not a fix.

After reading what Peter Campbell (RIP) wrote, The best course of action, in my view, shall be going single pane. Peter stated he did the single pane fix on 2 of his previous coaches & neither had issues. Pam has us routed to Arkansas in December. We are going to see friends from Little Rock AFB. I’ll go to visit th RV Fog Dr in Searcy, which is right up the road. http://www.rvfogdr.com/

Thanks

Does going to single pane have any downsides? I would imagine that single pane windows are going to be more prone to condensation on the inside of the windows, especially in colder weather and lots of people in the coach (or when cooking the right stuff). But if one tends to minimize operating the coach in cold weather and minimizes the number number of people in the coach, that should reduce the condensation events.

Maybe I’ve talked myself out of the need for two pane/thermopane side windows in the coach and we should be able to live with single pane windows.

Does anyone have any insight into why there isn’t a good, working, reliable two pane/thermopane fix for these windows? Are the seals necessary to keep moisture out from between the two panes of glass forever doomed because of the movement and flexing as the coach goes down the road?

You boys and girls with relatively new coaches … say 2014 or 2015 or newer, I wonder how long the seals on your two pane/thermopane windows are going to last.

I have dual pane windows except for the windshields and toll windows.

On certain mornings the toll windows get condensation and unless I want to wipe them with a towel I am going to have to live with the fogging. I have the vents turned to the windows but once they fog it takes a lot of air to clear them.

It is frustrating we cannot expect to have dual plan glass that lasts.

Dick, Noise.

I talked about it in the link I provided in my previous post above.

[Doug]

the RV Fog doctor folks emailed me back. They will not work on Prevost bus windows due to the design,

back to square one. Where is a good place to get a single pane installed? IE: ditch the doubles and get a thicker single pane replacement?

[Dan]

i am currently having all 3 replaced at Prevost Mira loma. They should be finished tomorrow. I cannot wait to have clean windows again.

Clear glass whether it is single pane or double pane has the same amount of heat gain when cooling. It is the tint that lowers heat gain when cooling. In the winter it reverses and dual pane does make a difference when trying to heat coach.

I think those who are contemplating some action to deal with fogging window glass should consider a “do-it-yourself” option.

I have dealt with the issue a couple of times and it is not the big deal it seems to be. The glass is held in place with Sikaflex. It is an adhesive product that can be cut with a utility knife. But cutting around the glass from the outside of the bus, and then from the inside between the glass and the frame the glass can be removed.

At that point if the fogging has not been a long term problem it might be possible to separate the panes, clean them and reseal the panes. This an easy job for a local glass shop. If the fogging has etched the glass the shop can use the two panes as a pattern and remake a double pane replacement or a single pane replacement if that is what is desired.

Replacement of the glass just involves a bead of Sikaflex around the part of the frame the glass rests against, and then after the glass is in place a bead that fills the gap around the perimeter of the glass between the glass and frame from the outside.

I had the driver’s side window, only the fixed part, fog couple years ago. Did what Jon said, cut the sikaflex around the perimeter of the dual pane and removed it. Then separated the two panes by cutting the caulk between the panes. Once separated cleaned the remaining residue with 3M adhesive remover. Took one piece to the local residential glass shop who could use it as a pattern to make one out of laminated for eighty bucks. But decided to just put one of the original panes back in. So I ended up spending only twelve bucks for a tube of sikaflex, and Prevost was the cheapest place to get it.

Strange how the slider window does not fail. It’s always the stationary ones. Prevost Nashville replaced My drivers window. 18 mos later same sad looking window. Blocking the view of the mirror.

SAFETY HAZARD I SAY

after reading the replies, this will be a DIY job. A friend, former XL owner has done this on 2 of his previous buses. Pam & I will adjust our travels this winter and drive to Florida and visit them.

when we do this, i shall photograph the process and post the pics here for reference

I have replaced the fixed driver window with Prevost provided replacement double pane. 2 years later it too fogged. Doing it myself was easy but time consuming.

I have just redone the drivers fixed for the second and last time, this time using a replacement window made by Peninsula Glass in Vancouver, WA. It took them 3 days to make a duplicate of my double pane in solid 3/8 inch thick tinted tempered glass. Cost $56. A tube of Sikaflex from Prevost was all that was also needed.

It does not have the little dots along the edge, which actually makes the window look much bigger, a real benefit.

Now I need to do the sliding part of the door window. How does that thing come out of the tracks?
