My son has just phoned me asking for advice. He went into his conservatory to find it covered in pieces of glass, the inner sheet of the glass roof had shattered. extremely puzzled has to why the outer sheet is still intact. Any suggestions has to what has happened.
Brother in law put a new light fitting up on his new conservatory it it was full of dangling glass parts and fairly heavy. I did say to him is that not to heavy for a conservatory as they are only made of plastic.
Sure enough the first day of heavy rain there was a puddle on the floor and water dripping of his new light fitting.
Has your son got any heavy type fittings on his conservatory that may add pressure to other parts of the roof.
My theory and only mine so probably wrong. But downward pressure on the glass would probably result on the bottom sheet of glass breaking first. And upward pressure would probably cause the top pane of glass to break first.
Or possibly toughened glass on the Top may stop that breaking so easy.
Maybe something falling of the roof of the house hits the toughened glass and bounces off but the vibration cracks and breaks the bottom part.
Did your son ever find out what actually caused it to break.
Update. Have just been on the phone to my son. It certainly appears to be a temperature problem, as he informs me the conservatory door was left open and he switched on his heating as he was on his way home.
Cymro. Sorry I missed your post. the major difference between the two conservatories is my son has a glass roof not polycarbonate and no there are no fittings of any discription attached the the roofing.
