QCondensation inside double gkazing

[Jofang]

Our 2016 Hymer has developed condensation inside the double glazing during winter. I was hoping this would rectify itself during sumner but it hasn't. Is there a cure fir this or must we replace the window?

Normally the double glazed plastic windows have a plastic bung towards the top corners as arrowed, and if you pop these out and heat the window with a hair dryer the moisture will evaporate off and you can then put the bungs back in.

It looks like the areas I have circled maybe bungs in your window.

As above. Or get Everest to replace the whole lot in their Autumn Sales

Acrylic is microporous which means moisture will penitate it, all vans get it nothing to worry about. As Paul says take the bungs out and either warm the window or just leave then out on a sunny day.

On a nice sunny day, remove the plastic bung that seals the window and let it dry out. You could also gently warm it with a hair dryer but that comes with risks if you don't spread the heat effectively. Then replace the bung with the tiniest smear of silicone grease and it may solve the problem. However before you do that look carefully right round the edges to see if there are any cracks etc. because the moisture must have got in somehow. Any cracks, its almost certainly a new window I believe.

Make sure you use 'silicone grease' and not silicone sealant though.

Interesting. We have had three vans used all year round and only ever had the problem with one window. On closer inspection it had obviously taken a swipe and had cracked on the top front corner. Hope I am not setting myself up here!

Every van we have had has had it in at lest one window from new. Tends to be when parked at home on the side facing north. Acrylic is microporous so water vapour will penitate it.

I Wish it was so simple, but our windows are glass not plastic.

In that case, I hope you have deep pockets.

If they are glass look for a local domestic window doctor. They specialise in sorting out sealed units.

I was fearing that it was a cab window. We had one go in the Le Voyageur and were lucky to get away with £500 bill and a 4 month wait for the window. Hymer windows can be eye wateringly expensive so best of luck getting it fixed

Everest came banging on my door ages back demanding payment for the double glazing they fitted almost a year before.
Said I hadnt paid them a penny in almost a year.

I said you told me they'd pay for themselves in a year...boom boom.

Cheers Bernard.

Common problem on the glass ones the seal goes. There are a couple of people in the UK that can repair them failing that cheaper to buy new units from Germany.

CN glass at Banbury repair double glazed units for motorhomes but you would have to get some one to remove your old unit and refit new one.

 

[Jofang]

As the window is effectively scrap I was considering drilling a 3mn hole top and bottom on the inner pane to allow a through flow of air and wondered if anyone had done this before?

 

[KUSKUS]

think it would shatter as its toughened.

Ditto, a right big bang and glass everywhere.

On our Hymer, I had both the static cab double glazed windows replaced with laminated glass, without experiencing any noticeable difference at all.

For the Flair, I have 2 x 11mm toughened glass replacements awaiting installation, in place of the 2 x 12mm double glazed units, which have also blown.

Cheers,

Jock.

Hi Jock
Can I ask where did you get tge glass and who did the work for you?

Hi Jock

For the Hymer, (many years ago though), I had to go to a chap over Telford way who specialised in ARV window replacement. I paid £250 per window back then.

For the Flair, a friend of a local glazing merchant, was instrumental in the supply of glass.
I just need a hand to remove the frames and replace the units.

My enquiries re having the windows removed, split open, cleaned, and re vacuumed, were to cost just as much as getting replacements made up.............but a damn sight cheaper than Hymer or Travelworld themselves.
Have a chat with your local glass merchant.

Does your insurance policy cover glass replacement?

Cheers,

Jock.

 

[Jofang]

Thank you JockandRita, this is good information. I like the idea of 1 piece glass rather than a double glazed unit so no chance of it ever happening again.

Our Hymer d/g units failed within 2 years of buying not really fit for purpose they were all changed under warranty.
we now have a Carthago and are about to have the front cab window changed under warranty due to moisture inside the glass they all seem to fail at some point, Lenny HB hope your new Carthago has not got double glazed cab windows but being a light chassis it probably won’t due to weight result

Jofang, purely as a temporary measure to clear the condensation, turn that side of the cab facing the sun, then put a black bin liner on the inside of the condensed unit, and trap it with the concertina blind. The heat will dry out the condensation, but for how long is the big question.

I successfully did this to enable an MOT pass, and to get by until I could replace with single glazing.

Cheers,

Jock.

What a star, thank you Jock. Getting through the test is my biggest concern, as the amount of condensation is not enough to be a hazard to safe driving.

Hi Jofang

Good advice from Jock, you might find that it is pretty easy to get the frame out then all you have to do is split it and use your old window as a template for the new one be it either double or single laminated, I know Jocks experience would suggest that double is more trouble than it's worth and can't argue with that.

I have a thread on here somewhere detailing how to remove split and replace a frame but every van and install is a little bit different so you need to make it us as you go on a little.
