I have a 6 month old Swift Sprite Major 6. On returning from only our 3rd trip in the new van, today, the front window cracked about 15 minutes into the journey.  My first thoughts are that something had hit it but on closer inspection there are no signs
of any impact.  My theory is this:  It's a sinlge piece front window, the double glazing unit is bonded at the rim all the way round. We have been away for 3 days with the thermostatic heating on 24 hours a day.  When we left the site the air in the cavity
and the temprature of the perpex reduced so quickly that it caused it to shatter. The main crack is from where the two panes bond at the top but the perpsex is shattered in a few places.  I would love to hear your thoughts and any proposed courses of action.
 I could start an insurance claim but I'm not sure if it's an accident or a manufacturing defect? 

Any advice would be much appreciated.
