We had a conservatory built around 2 years ago and have had absolutely no problems with it until the other morning when I saw that the inside (toughened) glass of one of the double-glazed roofing panels had 'exploded' during the night and the floor was covered in glass granules.
Fortunately the outer of the (was) double-glazed roofing panel is intact so the conservatory is still 'waterproof' but I'm very puzzled about why this could suddenly happen for no apparent reason more than two years after completion.
I looked carefully to see if there are any structural cracks in the structure of the conservatory that could account for the problem but could see nothing.
Has anyone had any experience of this sort of problem with sealed glazing panels so long after installation and is able to offer any suggestions about why it might have happened?
Fortunately we have a 10 year warranty on the conservatory and a replacement sealed unit is due to be fitted during the next couple of weeks.
Any thoughts anyone?
TIA - Dave.
