Welcome to the Bunnings Workshop community Chris (@Cwdl). It's fantastic to have you join us, and many thanks for your question.
Was it the glass panel system or the aluminium?
If it was the glass panel system, it is due to their compliance and usage regulations. The balustrade panels are not only toughened but have gone through an additional heat soaking process to ensure they are safe to use on balconies. The pool fencing is not compliant as it is only toughened glass.
