Rock door have gone downhill, at least the ones manufactured in Bury near me.
They stopped using a silicone seal around the edges of the glass and instead started using a foam tape, which doesn't do the job properly. We had a panel fail about 4 times, all due to water getting into the gap around the glass. So in the end we sealed it up ourselves (voiding the warranty) just so we wouldn't have to keep going back to the job.
Also, you have to go horrifically expensive to get the Rock door that is A rated and the highest security. They still put a fairly cheap barrel lock on it, for the price of the top rated model i'd have expected ABS cylinders.
