Double-glazed conservatory glass shattered

We had a conservatory built around 2 years ago and have had absolutely
no problems with it until the other morning when I saw that the inside
(toughened) glass of one of the double-glazed roofing panels had
'exploded' during the night and the floor was covered in glass granules.

Fortunately the outer of the (was) double-glazed roofing panel is
intact so the conservatory is still 'waterproof' but I'm very puzzled
about why this could suddenly happen for no apparent reason more than
two years after completion.

I looked carefully to see if there are any structural cracks in the
structure of the conservatory that could account for the problem but
could see nothing.

Has anyone had any experience of this sort of problem with sealed
glazing panels so long after installation and is able to offer any
suggestions about why it might have happened?

Fortunately we have a 10 year warranty on the conservatory and a
replacement sealed unit is due to be fitted during the next couple of
weeks.

Any thoughts anyone?

TIA - Dave.

Toughened glass does that sometimes. To do with the internal stresses
caused by heating it to toughen it.

Sometimes when a DG unit gets struck by something the reverse side of
the panel can fail rather than the one that got hit. With conservatory
roof panels it only takes a bird dropping something on it from a height.

Possible glass fault? I had a new DG panel (not toughended) sprout a crack
out of nowhere about a year down the line.

Next door neighbour had a side-panel in their door "go" after 20+ years,
just happened one evening when they were in the house, nobody near it ...

I had exactly the same thing with a conservatory roof panel about 20 years
old. The insurance company wouldn't cover it because they said it was due to
"atmospheric conditions" (temperature) causing the panel to expand against a
glazing bar and subject itself to stress. Needless to say I changed insurers
at the next renewal.

Hi Dave,
I have just had the same problem only I have had 2 roof panels and 1 side glass shatter 2 1/2 years after completion, with no apparent reason.
Would love to discuss this with you.

It can be caused by subsidence gradually twisting the conservatory roof and putting an increasing stress on the glass until one day a pane goes 'pop'.

I could have written this post since exactly the same thing happened to
me. We are under a 10-year guarantee so that was OK but I was very
concerned that my grandchildren might have been playing in there at the
time. The company concerned was defensive when I sought compensation for
distress and inconvenience (it took over a month to check and put right),
implying (I think) that this does not happen without some kind of impact.
The weather had been extremely hot that day so I imagine thermal stress
could have been the cause. Clearly it can, and does, happen.

Its usually a chip like you get in windscreens that due to vibration or
other effect suddenly breaches the toughened outer layer and the rest just
falls to bits. it happened on the inside pane of a door in a room we rent a
couple of years ago. We think some kids kicking a ball might have finished
it off. the outer pane was untouched though, which does seem a little
peculiar.

It would be impractical if they couldn't.

I hope that doesn't mean all the other panels in my conservatory are
going to spontaneously craze!

Edit: having read the article, it probably doesn't.

This might assist you with posting to a newsgroup, albeit through a website:
https://tools.ietf.org/html/rfc1855

- If you are sending a reply to a message or a posting be sure you
summarize the original at the top of the message, or include just
enough text of the original to give a context.


It will be a true miracle if 'Brian', assuming he's a real person, that
he actually replies to this thread!

Its a common theme to see just first names from the 'dark side'.

Hey you folks are improving, that post was from only 5 years ago.
