Has anyone got or know where I can get polycarbonate glazing from, as kids keep breaking the glass. Its a bit of a vandalised problem.

B&Q have packs of poly glazing for their range of greenhouses.
AFAIK you can buy just the glazing.
If that's no good then look at the polycarbonate sheets that they also sell -pricey though.

i allways stop when an old bus stop gets vandelised and pick up theold perpex sheet up if someone slips on it it could be harmfull i doit for health and safety issuss and its good for my greenhouse

HI
WE did our greenhouse in polycarbonate sheets. we got them from a supplier on e bay.
It was around £150 for the whole greenhouse, but if you replace bits as they get broken, probably not be so bad.
