Spontaneous shattering of double glazed panels

Hi all,
We purchased an add-on conservatory from one of the large UK
suppliers about four years ago and since then we have really enjoyed all
of the benefits of a warm bright place to sit and relax even when the
weather outside is far from ideal.
However, our enjoyment has not been without its downside since one
morning about 18 months ago when we went into the conservatory we
noticed that the inner glass of one of the many double-glazed panels had
shattered into 'a million' pieces for no obvious reason.
Since our conservatory came with a 10 year warranty, we contacted the
company, explained the problem to them, which they accepted without any
fuss, and they then arranged for one of their fitters to come and
replace the panel, which they did a couple of weeks later.
All was fine for another six months then the inner glass of a
different double-glazed panel shattered overnight in a similar way. The
conmpany responded in exactly the same way and the new faulty panel was
replaced under warranty.
A couple of days ago we were sitting quietly in the conservatory when
there was a loud bang and the inner glass of one of the other
double-glazed roof panels exploded and loads of fragments of glass
showered down around us. Now, for a third time, we have had to contact
the company who, once again and without asking any questions, have
ordered a new panel which will be installed during the next couple of
weeks.
Wen I spoke to the company I asked if this was a very common
occurrence and was just told that 'yes, it happens'.
Should I be reassured with that casual answer? Why has it always been
the INNER of the panels that fails? Nothing can have dropped onto the
conservatory roof from above and we don't play any hard-ball sports in
the conservatory. All very strange.
I've done a very close inspection of the structure of the
conservatory, paying particular attention to the frames around the glass
panels to see if any of them have become distorted but I haven't seen
anything that could explain these three glass breakages.
I'm grateful that the faulty panels have been replaced (to date)
without any hassle from the company and at least I've got another seven
years of warranty remaining so can hope that any manufacturing faults in
the glass of the remaining panels will have come to light (pun
intended!), one way or another, before that warranty expires.
I've done a lot of Googling on the subject and discovered that
spontaneous shattering of toughened glass panels for no obvious reason
is very common, both in the UK and around the world. Sudden temperature
changes don't seem to be the cause - the general view seems to be that
it just happens sometimes. One explanation offered is that small
impurities were in the glass during the tempering process and these can
'grow' over time (months or years) to a point when they cause the glass
to shatter suddenly.
I'd be very interested to hear the comments of anyone else in this NG
who have experienced similar spontaneous shattering of double-glazed
panels and how the suppliers of the faulty panels have reacted.

no room for the glass to expand. Given your history of problems I think
you'd be justified in asking the company to inspect the fitting of all the
glass in the frames.

that is deep enough to act as a stress concentrator. The flexure of the
building with cyclic heating cooling and wind loading gradually makes
the crack grow until it becomes self sustaining and detonates.
It is even more alarming when it happens with a toughened glass jug of
water and the whole thing disintigrates into 5mm pieces.
If it happens too often then I would be inclined to blame either rough
handling by the installers, something you are doing or bad design.
I'm a bit surprised it is always the inside. At a guess the outside
cools faster and the frame is slightly too rigid so that the inner
surface is in tension. One of mine has a small chip caused by the lawn
mower flicking up a stone which so far has survived more than a decade.

That can't be right Martin. If the outer was cool and shrank faster,

it would put the outer in tension and the inner in compression.
(You may be thinking of a single sheet of toughened glass which is
made by cooling the surface rapidly. The surface layer shrinks and
deforms the inside plastically. Eventually the inside cools and
shrinks, but the outside is solid - so the inside ends up in tension
and the outside in compression.)

Fair point Martin. That makes it even more surprising that the inner

surface goes pop and consistently at night. I still think is is either
related to differential expansion or mistreatment/abuse of the panels.

I've had a car window do this after 10 years, the panel stayed together
though and the inclusion that initiated the breakage was still visible
(happened on a sudden frosty night).
Also, I've seen it happen to thick architectural glass panels in a high
profile building. Seem to be the luck of the draw - possibly a bad
batch of glass in this case.

The car is several years old, but it was in winter, although not in a
particular cold spell.
Whatever.
A colleague of mine in the US once had a similar event while crossing
the high bridge where the Interstate crosses the Rouge River outside
Detroit, but the cause was a large piece of metal that came in through
the back window, and landed behind his passenger seat. The puzzle was
how it got there at all, he was high above ground level, and there were
no lorries anywhere near him at the time.

As well as having the company inspect all the remaining panels, I would think about fitting an adhesive safety film to hold the pieces together if/when another panel fails.

Yes it happened to a smoked glass mug about a year ago. it was just sitting
there on the table with water in it. There was a dull thud then a dripping
sound, so I went in and found a miniflood with tiny bits of dark glass in
it. Most odd.
I've also had strange things happen in greenouses with plastic sheet going
bang, turning black and all scrumpled up and brittle. i assume this is some
kind of sun damage, which is not really welcome in a greenhouse!

I was just thinking that myself, but another thought struck me, is there
any gass put in these units that might expand, and is the inner glass the
same thickness and type as the outer one is?

it would have been about £200-£300 if I had paid myself, and it was a
hard to find piece of glass. I'm glad I didn't try to fit it myself, it
looks really complex, what with fitting into the slots, various power
connections, wiper motor and arm, and struts. Well worth the deductible.

of a bang and I discovered that a plastic trim piece behind the rear

from a hunter as the area was forested. Luckily it didn't hit any glass.

I lived and worked in Michigan, Ohio, Indiana, New Jersey, New York,
Illinois, Minnesota, California, Tennessee, Georgia, Kentucky,
Maine, Connecticut, Virginia, North and South Carolinas, and maybe
more, and visited many more. In none of them were the words 'fortnight'
or 'twice' ever used voluntarily by any American I met, and if I used
them, I got asked what I meant when using them.
Another oddity is the use of 'one-half' instead of 'a half', as in:
English: "He took the corner too fast, and rolled the car one and a
half times".
American: "He took the curve too fast, and rolled the car one and one
half times".
It always sounds odd to the English ear.

Hi Dave,
We have experienced exactly the same thing. We also have a conservatory
from a major supplier, fitted just under 4 years ago. Last June, we came
home to find the inside pane of one of the large glass side panels
completely shattered. No-one was in the house at the time. About two weeks
later another panel shattered in exactly the same fashion. Both panels
went on relatively cool days, so heat excessive heat expansion could not
be the cause.
To date the company has replaced the two panels without question. However;
last Sunday there was a terrific bang and we were horrified to find a
third panel has shattered - again the inside pane on another relatively
cool day and again, fortunately no-one was in the conservatory at the
time. This time the site manager visited and has quibbled about the
guarantee. He did not offer any kind of information, or have any idea as
to the cause, other than 'it happens' - more than that, he seemed
unwilling to undertake any investigation - not at all re-assuring. We are
pushing to get the panel replaced under the guarantee, as we think it is
down to impurities within the glass and is therefore clearly a
manufacturing fault.
We are not all reassured that it won't happen again. Each shattering has
left a fine carpet of very sharp glass fragments on the floor, even though
the panel has stayed intact in the frame. I am not reassured that it is
not potentially dangerous to either us, or our pet dog who likes to soak
up the warmth. We have asked for a full investigation, but it doesn't seem
as though this will be forthcoming.
I would be very interested to hear of other's experiences.
Kind regards,
Tony

You only have the doors to worry about.
I'm amazed about the roof panel.
Only the lower panels need to be toughened glass.
You might ask about this aspect.
They are here as a safety thing, ie if someone/child accidently breaks one,
less chnce of getting cut up.
They are allegedly harder to break than normal glass.

It turned out to be subsidence of the dwarf walls, and thus the frames
were distorting, placing the glass under stress and then shattering.

What annoys me about postings from this portal is that for those reading in
the normal traditional way, ie not on the web but via a news client, unless
the poster specifically adds it, there is no indication of how old the
thread/topic is. I doubt anyone wants to go on the web to read it on there
to find out the true context or whatever they say, actually is.
Anyway, this thread topic seems to come up on newsgroups quite often. I
suspect it has something to do with some stress on the panel, and with
temperature cycling and the brittleness of glass, sooner or later something
breaks.

That's odd. For you to have 4 failures makes me suspect that there is
some underlying cause, and it isn't just coincidence. But 10 years is
long enough that the local vandals should have grown out of it.

they declared bankruptcy and then start trading under the same name

Yes and watch out for hidden or missing dates.
However if i had a quid for everyone who seems to get this spontaneous
shattering normally of the inside pane and often in conservatories a few
years in, I'd actually make more than what I make having money in the
building society. My guess is that sometimes there are stresses when these
units are fitted and eventually something has to give.

Even I have heard of this. They normally put it down to stresses in the
fixing or the assembly of the unit. You then only need a tiny flaw and
stress and temperature tend to make it fail.

slight damage during assembly; stresses due to how it is installed;
nickel inclusions from manufacture, among others.

Yes this query comes up with amazing regularity. I wonder if the panels are
under some stress and eventually the glass simply gives up and fractures.
I wonder how long one can assume a double glazed unit can last. Most of mine
have been extremely long lasting, indeed some from the middle 1970s! Yes
they are narrow gap, but are still good. One has a tine crack and I suspect
moisture is inside by now.
The modern ones though do seem less robust.
I guess if they last too long though, nobody would buy a new one... grin.

them and then with heating and cooling the crack elongates. The sort of
thing that a stone thrown up by a lawnmower might inflict. You will
never find it after the thing has gone pop you you can sometimes see
such damage when cleaning the windows (or car windscreen). I do have one
window with a visible stone chip but so far it has held out.
One of mine in normal glass double glazing has failed about a decade
after someone broke into the house by forcing the adjacent opening
window. I presume the stresses cause by deforming the aluminium frame
and steel reinforcing eventually got to the glass and it went ping in
the hot sunshine. If the frame itself is being deformed by the building
moving then all bets are off. Glass is not really very flexible (though
it bends by more than you might think). My greenhouse failed that way.

unit has (at least) some water vapour in it and isn't therefore an ideal
gas. The better ones are often filled with some inert gas when new, or
at least dry air. However, if the the seal has failed, chances are water
/ water vapour had got in and a this is causing the problem. (Water
vapour is a polarised molecule and that stops it being an ideal gas, if
I remember my Physics.)

The concept of an ideal gas is based on theory.

gasses, whether they have water vapour in them or not. However, some
might approach ideal behaviour depending on the circumstances.

Hi, we have just had the same problem. Inside window of double glazed roof panel blew and shattered everywhere. I was sitting under it, luckily was agile enough to move quickly, but if a child, elderly person or my animals were sitting underneath it could have killed them! The conservatory’s only 2 and a half years old, Creative View who built it all say ‘it’s common’ and say our 10 year guarantees and insurances don’t cover this (?) and want £1200 to fit a new panel!! Given there are lots of panels and they give no explanation of why or would even visit to check, I’m to scared to use the conservatory again, or let anyone else in there.
Anyone know how to prevent this happening again? Do I not use heating in there (though it wasn’t on as it was 9.30am on a sunny morning and the doors were open).
Or where to get protective film (as a previous post suggests).
Or some sort of netting to catch the glass?
Thank You

I had a Velux roof window (double-glazed glass panel) spontaneously
shatter earlier this year (one of four in the kitchen) that was
installed 2002-3 time-frame. It turns out this is a known problem and
Velux have a formal recall programme
https://www.velux.co.uk/safety-warning-new . A contractor came out
within a day to make the panel safe and a few weeks later all the panels
had been replaced. I was very impressed with how Velux handled this.
As an aside, the serial nos of our glass panels weren't flagged by the
website checker as being covered by the recall but I sent photos to
Velux who promptly decided we were eligible.

Myself I'd query the warranty not covering it. After all if it is known to
be a problem then are they supplying dangerous products?When mass producing
units the cost of the proper glass for the inside would be minimal I'd have
thought. Besides it would be nice to know what eye mechanism for it is.

That sounds like a great service, well done Velux. I’d definitely look into their products in future.
Sadly the company I used (Creative View in Clacton) have no interest in helping us, or customer service with reassurance if it will, or might happen again.
We have tried to challenge the warranty /guarantees to no avail. Their only comment is we can get another glass unit, but it won’t be the same colour, it’ll cost £1200, take 2-3 months and they want 75% payment up front!!!!
I’ve asked other glazers (we’ve been quoted approx £280 - £300 by four different ones), but using someone else will probably invalidate our original 10 year warranty, and guarantees, if there’s any other issues (not that the guarantees seem worth the paper they are written on!!).

Hi Dave yes this happened to us yesterday . Luckily we were out or we would have been hurt . A window in the roof blew our security camera filmed it .So nothing had hit it .

Hi Linda, let us know how you get on with your installers and the guarantee and what they say. My guarantee was for ten years, but they won't honour it as they said /"our guarantee does not cover the natural phenomenon of Nickel Sulphide", but we have had an independent report and the panel came out, exposing a screw that was badly fitted, sticking outward of the frame and into the side of the glass panel. We have been told the settling of the build and the glass panel can only take so much stress and this is the cause. Our installer are adamant this would have happened instantly, not two years later and won't help us in anyway.
If anyone else can shed an opinion on this screw, we would be grateful to hear it and also from you Linda on the findings of your installation company and what they do about it.

Hi I have just found your message about shattering internal conservatory glass roof panels. This morning we have woken to this experience and we are wondering if the company may be the same. Have rang them this morning and been told not covered by insurance. The company fitted 4 years ago. With live in Nottingham area.

Hi PJS, firstly sorry to hear it's happened to you. I doubt it's the same company, mine was Creative View Clacton, Essex.
I had an independent person look at mine as the company weren't interested, and it turns out to be a wayward screw (shoddy workmanship), but I still haven't got anywhere.
I think these companies get out of having to honour their guarantees/insurance, by blaming "Nickel Sulphide" inclusions, without even checking their installation or going to their glass manufacturer for advice.
My understanding from all the 'homework' I've done is it's usually a bad batch of glass or bad fitting, either way it's possible it could happen again if it's the same batch of glass or the same fitter!
Good luck, keep me posted on how you get on, I'm still trying to fight it because on our guarantees there are no 'exclusions' stated, so assumed we would be covered. We had 17 panels in our roof, I don't want to keep paying £1200 (plus all the damaged furniture) every time one explodes!!

Today 19 September 2021. This has just happened to us. A loud bang when my wife was in the conservatory and I was in the adjoining kitchen. The end inner pane of a double glazed roof panel suddenly shattered. Within about 15 minutes the shattered crystals of broken glass started to fall. The hard wood conservatory was constructed and installed in 2005 which is 16 years ago so no guarantee on the windows. The outer pane appears to be OK for now and there does not appear to be any impact evidence either inside or out.

I'd think there was a tiny crack and the pane was under some uneven stress,
and then just like windscreens the thing just went.
I'm rather surprised that in roofing units they do not have a layer of
plastic film over them to stop the dangerous chards from falling on
somebody.

2005 so nothing to do with Brexit or covid at least, so must be global warming. :-)

At first I thought you meant that the inside and outside panes had both

shattered, which would have suggested an object striking the window from
outside and penetrating both panes.

Toughened glass breaks into thousands of small pieces when broken. It
would be very unlikely to cause anything other than a few minor cuts or
scratches.
FWIW our conservatory has been up nearly 9 years. None of the glass
panels have broken. In addition, some are unusual shapes (including
three and five sided), so stresses might be higher on those.

This problem seems to have been going on for many years. Has anyone come up
with a cause, or is it that the weight of the pane if used as a roof just
cracks and falls in?I'd have thought a glass coated in a plastic film might
have stopped this.
