Hi David,
I used an aquarium calculator to calculate the glass thickness, so the piece of glass going in will be 290cm x 60cm.
The glass will have water 15cm from the top so the area underwater will be 290cm x 60cm. For this it seems that 12mm is enough to do the job.
I saw that toughened strengthens the glass by 5 times which is why I thought it would be safer however having read more on that front now the thought that if damaged the window could shatter into thousands of pieces I am definitely agreeing with you and staying away from that!
However with the laminated option it does mean that if the glass broke/cracked for some reason it would hold in place and then you would have a slow leak maybe instead of the water just gushing out in one fall. When I have visions of dead fish all over the lawn this feels like a safer option to me?
I have contacted the glass manufacturors regarding the safety and load difference between a normal glass sheet and laminted to see what they say. I would pay the extra if it was safer. I am surprised there is not more information about this kind of thing online or maybe I am not using good search terms on google! lol
I appreciate anybody's input and advice into this - past and future. Thank you all!
