slamming patio doors
 

With all the regulations to comply with, one would have thought the
issue of upvc patio doors slamming might have been addressed.
You can hook them back in fine weather (assuming you know where to put
the fixing to avoid fouling the hardware inside, and are confident that
self tappers into a single thickness of plastic is sufficient) but what
about weather like we're having now? Kids never close doors behind them
so either the doors or the kids are likely to suffer.
Does anyone know if there are "soft close" hinges available or a door
closer suitable for upvc doors?
