That was one of my thoughts but there’s no feathers and all the broken glass was outside the vehicle. Not in the sun (this is England!) but one of my neighbours suggested thermal stress combined with a defect in the toughened glass
Both top and bottom righthand corners of the window appear damaged - as this is where the glass is at its weakest, that's where I suspect an impact has occurred. Have you recently p!ssed off a neighbour that access to an air pistol?
What happens is this: the glass gets a bit bigger when it shatters because there is a space (air gap) in all the cracks. It is fixed to the door all round the edge, and is curved outwards. Hence the center of the sheet is forced outwards on the convex side and bits drop out this relieves the stress so the rest stays in place. The actual origin of the failure may never be evident. But likely a stress issue such as a sudden change in temperature or a minor impact.
This just happened on my t5 today - exactly the same. Trade Glass UK. They are sending me a new one tomorrow hopefully - it was only installed a month ago. Today was the hottest so far this year, my sliding door was open at the time so it was not caused by a high temp inside the van. Must be the heating of the glass/metal direct from the sun. I was in the garden when I heard a loud pop, so I went to the van to find glass on the driveway, sprayed as far as 3 meters away, I then saw this huge hole where the window had literally exploded outwards. I’m just glad no one was behind the van at the time.
Yep, exactly the same as mine. The guy who came out and fitted my new glass suggested it was thermal but it did cross my mind that I have a towbar mounted bike rack and it's possible that the handlebars of the bike nearest to the back of the van could bang on the glass if there's a serious bump in the road.
