Shattered double glazed window

At the origin point of the failure can you see what appears to be a ‘butterfly’ or figure of eight as below? If so the failure is probably caused by a nickel sulphide inclusion which can expand spontaneously and crack the glass. If not, it sounds like an glass edge defect.

it’s a child’s room -

So, to what kinds of toys, including other things in the house, does the child have access…? The inner pane only, in a child’s bedroom, does suggest a possible mishap, with the child too terrified of consequences to admit to doing.

Please note, this is offered as a genuine thought, and not in any way intended to reflect in any way on your child, or your parenting etc, just aware from my own experiences both as a child and as a parent that all sorts of things can happen, whether entirely accidental or simply out of lack of awareness of possible effect.

Thanks.

I’ll check at some point in coming days - I’ve covered it over for now in case it collapses.

That went through my mind, I think it’s unlikely though I did ask.

Absolutely - as a lad when we had a big snowfall and dad’s glasshouse roof was covered in snow, I decided it would be a good wheeze for a friend to a lob a snowball onto the roof causing an ensuing avalanche to cover me, stood by the glasshouse close to the roof. The plan was for another friend to film it (super 8 film). Not sure what I did but somehow managed to smash several panes with my foot as the snow fell - lucky I was wearing ‘wellies’ I suspect. When we processed the film the spontaneous expletives from me were a bit of a surprise to the family.

I did the lawnmower/stone thing to a window in the kitchen door. My Insurance company sent a glazier out that day who put a film over it to stabilise the glass while they made up a new unit. There was no subsequent loading of my premium.
