Fogged Double Pane Window

Suncoast Designer in Hudson, FL repairs them. Also, RVFogDr in Searcy, AR. Are they frameless? RVFogDr told me they don't do frameless but Suncoast does

One of my double pane windows has fogged up. Has anyone had this problem and is it something that can be fixed without replacing the entire window? If so, any idea of the cost? The potrion that is fogged is about 15"x15".

We had all of the dual pane windows “Repaired” on our 2004 5th wheel! The window panes are separated, cleaned, and resealed. We even had our rear “picture” (quite large) window. Very pleased....so far!They were not filled with an inert gas....just done in a very low humidity (Mesa, Az.) environment! We had ours done at APR-RV. I’m sure there are other places that perform this as well.

They can be separated, cleaned and re sealed no problem!

Do a search on this site...Lots of threads about fogged windows here...

Thanks for all the info.

I've been working with glass for 40 plus years:

No need to replace the whole window. You can replace or repair just the glass.

In RVs, the hardest thing can sometimes be getting the durned thing out of there.

Being the part that opens is a bonus. Easier to remove.
I'll assume you can figure out how to remove it.

I've repaired a ton of fogged units over the years. Repair vs replace depends on how long it's been fogged up. If it's been a while, a few years, the fogging inside will typically etch the glass permanently. Then the whole unit has to be replaced.

Both sides of the sealed unit should be tempered glass.

If it hasn't been too long, there is a chance you can repair it.

The glass shop (or yourself) can cut the unit apart with a sharp utility knife. The spacer bar should be replaced always. There is a desiccant inside the spacer bar. Cut the unit apart, wash the fogging off the glass thoroughly, if it will in fact wash off. Razor blade the old seal off too. New spacer bar, reassemble and properly seal it. It takes a special compound to seal it with, and specialized equipment to apply it. Polysulphide or silicone are 2 common sealants used. In a glass window application, silicone glazing is better than polysulphide. It is more resistant to UV and vibration issues.

Worse case scenario, you take the unit in to them and they have to order a new one. It takes a place with a glass line to produce a new one. Most typical glass shops don't have that. Window manufacturing plants do.

I have actually done these repairs on a piece of cardboard on the tailgate of my truck. Not the best, but when you're stuck, you improvise!

Don't let anyone tell you it's a vacuum between the panes. It isn't.

Yes. Fogged dual pane RV windows is very common. All of mine failed in my 05 Fleetwood. If you can’t find a local guy you could ship the window or plan a vacation in Elkhart In next summer.

I got mine repaired at Suncoast in Florida. In the winter they have 20 coaches at a time in their lot.

Thanks, good news. Will they be able to keep the double pane?

You shouls be able to take the crank out window off, take it to a glass shop and have them replace it.

I guess I wasn't real clear. This fogged window is a portion of the rear picture window. It is one of the small lower windows that opens. I hope this makes sense. I am wondering if the whole picture window has to be replaced or just the one piece.
