I want to know if a window can explode out due to normal Perth,
Western Australian weather, even if it was 35 to 37 degrees celsius?
The room is 5m by 3m. It has two windows and a sliding door and it was
the sliding door that supposedly blew out. I f any body knows the
answer, please reply.


Windows are different than doors and so is the glass. A window did not
break, but a light of glass did. There are many reasons a sliding door will
blow out.

In the US, at least, door glass must be tempered. Tempered glass does not
break in shards like regular glass, but it fractures into tiny pieces when
broken. This makes it safer if a person or animal should fall against the
glass.

It may have been damaged weeks ago and finally, excessive or extreme
temperature of a good bang closing will cause the problem. It was not
necessarily the kids having a party.

I once found my favorite coffee cup shattered in pieces on my desk at
work. Very odd. Who would borrow my cup, break it, and then pick up all
the pieces and leave them on my desk? Inquiring around, I pieced
together the story.

Seems the previous evening, I had left the cup sitting on the back of my
car as I drove out of the parking lot. A coworker ran shouting after me,
but I didn't hear him. Miraculously, when the cup fell in the street, it
appeared totally intact and undamaged, so he put it on my desk. Perhaps
it was time, or a very minor change in temperature through the night,
that finished it off.

Before you shout irrelevant, I'm aware that glass and ceramic are two
different materials. I'm just trying to amuse myself over here until the
sun comes up.
