    I have a 2005 Burstner with acrylic glass double glazed windows.

    I noticed after a particularly heavy downpour today that water had built up within the unit (i.e. between the inner and outer window panes) in one window (the main habitation window). Nothing is leaking in to the MH itself, but a fair bit of one corner of the outer glazing pane has become unstuck/de-bonded from the rest of the window.... nothing is cracked and there are no holes, so I'm thinking that I can stick it back on.

    If this is the best course of action, what's the best glue to use for these types of window repairs? Any other tips? Thanks.

    Everyone's obviously off on their holidays touring... if anyone's interested, my internet research reveals that this was a well established design issue with the Polyplastic double glazed windows used by most MH manufacturers at this time. Burstner chose to do a formal safety recall to fix the issue (though obviously they didn't get to ours). Other manufacturers appeared to leave it to the owners to argue the case direct with Polyplastic. Unfortunately Burstner's UK tech support person is on holiday as well, so I wait to see whether or not they still apply the recall...

    If you have a MH aged around 1998-2005 and Polyplastic double glazed windows, apparently the Burstner fix was to fit nylon bolts through both panes, one in each corner - the rationale being that this was a safety issue (the outer pane might fly off causing injury to others whilst driving along) and so simply using glue to reattach it wasn't considered enough security. The Polyplastic fix appeared to be to offer a complete set of replacement windows at cost, or with a small discount... which seems a bit naff if the problem was their design fault. At the time this was costing around £750 a van.

    Interestingly, I see that Polyplastic - even today - have issues with various makes/types of windows in more recent MHs (not Burstner anymore). Check out their support site...

    @The Lobster I have used this a few years ago on acrylic but not Windows, it's very thin and just sucks into the gap by capillary action.

    Sorry about the link size.

    We bought our '05 Burstner in 2010, it had already had the window mod carried out on it (small plastic rivet in each corner) but they've still sent us two recall notices since.

    Brilliant - it's going in to a MH garage for something else and they're going to see what they can recommend for the window repair... failing which, this looks ideal - thanks.

    From other threads Burstner seem to have been very good at sending out the recall notice - so disappointing that the two previous owners did nothing about it :( - do you get any leaks into the gap between the window panels with just the rivets, or was it re-glued as well?

    Not sure exactly when it was done, but up to now there's been no sign of leaks or condensation, pity the same can't be said of the fit of the hab door :(

    Thanks - that's useful. The hab door on ours needs a fair pull to get it to shut properly, otherwise the seal isn't complete, but if we do that we get no problems with leaks there (or anywhere else for that matter).

    @The Lobster, I tried adjusting the lock position on our door but when I took a good look at it, you can see that the actual sides of the van pull in about 10 mm near the door's middle, where the side fastens to the fridge housing. It's obviously happened when the van was being constructed and I can't imagine rectifying it would be anything but a major undertaking. I'm looking to get some deeper profile door seal to make up the gap, but most of the stuff online seems to be the type that clips onto an edge and not the kind that slots into a groove. :( May have to try bonding something in place ?

    Have you tried asking Burstner UK via their web contact page what they suggest? I've found their technical support person very helpful - even with our old van - and if you think this is an original construction fault they may be aware of it from others of that model/year.

    For anyone coming late to this thread, the outcome (for us) was that we got the Burstner-recommended safety fix applied to all the PolyPlastic windows (essentially a small nylon bolt in each corner of the double glazed pane) and had the main habitation window (which had partly delaminated) re-glued. We're still waiting to hear if Burstner will provide any recall compensation - apparently it was recalled 4 years ago but the then owners ignored the notice. Burstner also confirmed that they'd (just) run out of the nylon screws, or they'd have sent us some... which is impressive for a 10 year old MH.

    Given how simple the fix was - and how serious the implications of a delamination are (if you happen to be travelling at the time) - we'd recommend it to anyone with this vintage MH and PolyPlastic windows.
